Abstract. Hazardous Waste Management is a special course offered to students whose major is
Environmental Engineering. It is offered to let students know basic knowledge and technologies of
hazardous waste (HW processing and disposal! so that the" can solve problems on HW processing
and disposal. With increasing development of processing and s"nthesis of substances! lots of
hazardous waste is generated as side#products. $s more importance was attached on environment!
re%uirement on hazardous waste management is more stringent than ever before. In order to
enhance the competitiveness of undergraduates in using English! it is necessar" to develop this
course as a bilingual course. &his paper first anal"zes the basic conditions of this course. &hen it
proposes a developing plan for the course from the following aspects' adjustment of the course!
reorganization of the te(tbook! teaching method! teaching mode! test database and e(ercise database
and wa"s to increase teaching %ualit" of this course.
Introduction
Hazardous Waste Management is a basic discipline of Environmental Engineering. &his course
presents an introduction to the general principals of hazardous waste management including the
following sections' definition of solid waste and hazardous solid waste! characteristics of hazardous
waste) basic knowledge of hazardous waste' paths! fates and disposition of hazardous! to(icit"!
sources! generators and transportation of hazardous waste) processing of hazardous waste'
introduction to processing methods! incineration! other processing methods of hazardous waste)
disposal of hazardous waste' general introduction! landfill gas management! leachate management)
reuse and rec"cling of hazardous waste and site remedial) medical*biomedical* infectious waste
management.
&his course targets undergraduate students! whose major is Environmental Engineering. &he
teaching mode is class teaching and discussion. &hrough the course the student can master the basic
theor" and principle of hazardous waste management. Meanwhile students also can master the basic
e(perimental hazardous waste treatment and disposal skills! including incineration! chemical
stabilization and solidification! landfilling! and etc. +" the theor" and practice students la" the
professional knowledge base in the future work on management of hazardous wste field and related
fields. In the teaching process! we pa" more attention to combination theor" with practice in order
to improve the abilit" of students to appl" knowledge to practical problems. In addition! we also
introduce the development direction and achievement of this subject during our teaching.
&o cultivate graduates of inter#disciplinar" talent! the Ministr" of Education began to promote
bilingual courses in higher education colleges and universities in ,--.! ,--/ and ,--0 1.!,2.
+ilingual course! teaching in both 3hinese and English! is promoted to provide a bilingual language
environment for students to promote their English proficienc" 142.
&his paper first anal"zes the basic conditions of this course. &hen it proposes a developing plan
for the course from the following aspects' adjustment of the course! reorganization of the te(tbook!
teaching method! teaching mode! test database and e(ercise database and wa"s to increase teaching

Construction of the course
Adjustment of the content of Hazardous Waste Management. +efore construction of this
course! major contents of the course involves ten sections' section one! basic introduction of this
course) section two! definition of solid waste and hazardous solid waste) section three!
characteristics of hazardous waste) section four! basic knowledge of hazardous waste' paths! fates
and disposition of hazardous) section five! to(icit") section si(! sources! generators and
transportation of hazardous waste) section seven! processing of hazardous waste) section eight!
disposal of hazardous waste) section nine! reuse and rec"cling of hazardous waste and site remedial)
section ten! medical* biomedical*infectious.
5iven actual English proficienc" of the students and their understanding abilit" of English
course! the content of the course was simplified to seven sections through the construction. In
section one (general introduction to this course! basic knowledge on hazardous waste is introduced!
involving aims of this course! development of hazardous waste management! current conditions of
hazardous waste management! major content of this course. 6ection two! basic knowledge of
hazardous waste! involves basic definitions on hazardous waste! wa"s and disposition of hazardous
waste releasing! to(icit" and standard#setting process! transportation. 6ection three! processing of
hazardous waste! includes basic introduction to processing methods! treatment method of
incineration and other methods for treatment of hazardous waste. 6ection four! disposal of
hazardous waste! includes landfill basic definitions! landfill gas management! leachate management
and cover maintenance. 6ection five! reuse and rec"cling of hazardous waste! involves pollution
prevention! waste minimization! reuse and rec"cling. 6ection si( is a case stud" of M6WI
(municipal solid waste incineration fl" ash.
Reorganization of the textbook. 5iven the fact that there isn7t a bilingual te(tbook on hazardous
waste management! it is necessar" to compile one. &he te(tbook was re#organized based on English
teaching materials +asic Hazardous Waste Management written b" +lackman! William 3 and +asic
Environmental &echnolog" written b" 8err" $. 9athanson. 3onsidering that special word is %uite
important for learning the course! special word sheet is involved in the te(tbook.
Each section involves five parts! purposes and objectives of the section! major bod" of section!
vocabular" of special words! %uestions and discussion and major reference. :urposes and objectives
of the section let the students know wh" this section is given and what the students should know or
learn through learning this section. Major bod" of the section is the most important part of the
section! which uses lots of pictures and charts to make it eas" to understand. &he vocabular"
includes the special words appeared in the section to make it eas" to understand. ;uestions are
promoted for discussion among students. <iscussion is re%uired each class to enhance
understanding of the teaching. =eference offered at the end of the section can tell students where to
get the knowledge if the" are interested in the part.
Teaching method. Hazardous waste Management is taught through multimedia! including ppt
(power point and 3$I (3omputing $ided Instruction. 3ompared with common courses taught in
3hinese! the bilingual course needs vivid teaching methods to make it much easier to understand.
$s the human knowledge is not e(plicitl" saved in the digital librar"! but is implicitl" e(pressed in
different media such as te(t! image! audio and video. &herefore! it is necessar" to effectivel" e(tract
the re%uired knowledge and information from multimedia resources 1>2.
Multimedia refers to combination of a variet" of media#te(t! graphics! sound! animations! video
and other visual information to make up an application s"stem. Multi involves multisensor"
function! multi#facilities and multi#field. It involves all aids that ma" be used b" teachers and
students to attain certain educational objective 1/2. :pt and 3$I are two important wa"s of
multimedia.
3$I courseware is one of modern interesting teaching methods. It has aroused general concern
of schools at different levels and related computer software developers 1/2. 3$I is a good choice for
teachers to make the class attractive. ?or e(ample! microwave digestion of hazardous waste in
measurement of heav" metals and other components can be easil" understand using the 3$I of
3EM microwave description video. It is clear through the 3$I! how microwave is released! how
microwave works and wh" microwave is much better than other means! e.g. traditional heating.

:pt is used in multimedia teaching. &o make it vivid! diagrams or pictures are used to describe
some definitions or phenomenon. ?or e(ample! the structure of a landfill is clear in ?ig. .. It is
apparent that a landfill involves liner s"stem! landfilled waste and covers. In addition! students can
easil" understand differences among dail" cover (covers used after operation each da"!
intermediate cover (cover used on a lift and final cover (cover used after landfiling operation is
finished.

?ig. . 6tructure of a landfill
Teaching mode. ?irstl"! both 3hinese and English are used in class. &e(tbook is in English. :pt is
offered in English! While 3hinese is allowed if it is necessar" to make a much clear e(planation in
3hinese. ?or e(ample! 3hinese meaning of some special word can be provided in ppt to make it
much easier for student to understand and make notes. 5enerall" speaking! English covers no less
than /-@ of the class. 6tudents are encouraged to answer %uestions in English. However! the" can
also use 3hinese if it is difficult in English.
6econdl"! teaching and participating of students are both important for understanding of this
course. &eaching with ppt or 3$I is re%uired to e(plain the knowledge to let students understand.
<iscussion and presentation are two wa"s for students to participate in the teaching of this course!
which are active learning and have better effects than passive learning. <iscussion is a good wa" to
enhance understanding of the course. <iscussion is fle(ible. &he students are encouraged to sa"
an"thing on the problems promoted for discussion. In addition! the students are re%uired to make a
short#term presentation! which is a good wa" to have a deeper understanding on some subjects.
Test paper database and exercise database. &est paper database and e(ercise database are
necessar" to check if the students grasp what is taught in the class. +oth the test paper database and
e(ercise database cover all content of the course. E(ercise database involves special word
translation database! definition database! diagram e(planation database! simple e(planation
database! paragraph translation database and computation database.
&est paper involves si( of the following seven t"pes of subjects! translation of special words!
making choice! filling close! e(planation of definition! answering %uestions! computation and
translation of paragraphs. &ranslation of special words is made based on vocabular" in the te(tbook.
Making choice involves single choice and multiple choices! which is based on discussion in class
and is much fle(ible. 3lose is based on basic knowledge that the students should remember.
3omputation comes mainl" from incineration and landfilling of hazardous waste. :aragraph
translation comes from translation of te(tbook in class.

Was to impro!e teaching effect. &o improve teaching effect! the following aspects are %uite
important. ?irstl"! choosing an appropriate te(tbook is the first step to a better understanding of the
course. &he te(tbook should meet the actual English level of the students. Hence! a difficult
description is not appropriate. 6econdl"! improvement of the bilingual course teacher English level
is an important guarantee for a good presentation of the course and an good understanding of
students on what is taught. &hirdl"! providing a bilingual course environment where students can
communicate both in English and 3hinese! but mainl" in English! to practice oral English. ?ourthl"!
participation of students in class should be encouraged to enhance understanding of what is taught
in class.
Conc"usions
&his course targets undergraduate students! whose major is Environmental Engineering. &he
teaching mode is class teaching and discussion. In order to maintain the competitiveness of
undergraduates! it is necessar" to give the course in bilingual language! especiall" those who stud"
in Environmental Engineering. &hrough leaning this course! the students should know basic
knowledge of hazardous waste! hazardous waste treatment and disposal technologies and how to
reuse and rec"cle hazardous waste.
5iven actual English proficienc" of the students and their understanding abilit" of English
course! the content of the course was simplified to seven sections through the construction.
Hazardous waste Management is taught through multimedia! including ppt (power point and 3$I
(computing aided instruction. &eaching and participating of students are both important for
understanding of this course and improvement of the teaching effect.
