A new process has been developed in treating train laundry wastewater for recycling. In the work, the process of coagulation-sedimentation and SBR has been researched, the results has shown that the characters of the wastewater was great improved by coagulation-sedimentation under the conditions of 80mg/L of PAC as coagulant and 30mg/L of APAM as coagulant aid, and then by SBR under the conditions of 2.0h of anaerobic time, the effluent concentration could achieve the reuse standard of GBT18920-2002, and it could be applied for miscellaneous use.

Recently, the light materials have been applied in order to reduce the cost of construction. Since its soundproofing is generally poor, it presented a new problem of noise pollution for office building during our noise control projects. Based on “Acoustics - Specifications for the Design of Sound Insulation in Civilian Structure” （GBJ118-88）and taken an office and meeting room for examples in a building, the good soundproofing material was selected and researched and its performance met the noise requirement of various rooms through compared with performance of soundproofing for various wall material. As a result, the noise of office and meeting room reduced from 67.2 dB (A) and 57.3dB(A) to below 55dB(A) and 50dB(A) separately.

Industrial Wastewater Treatment is one of the main special courses offered to undergraduate students whose major is Environmental Engineering. It aims to let students know basic knowledge and control technologies of industrial wastewater pollution, so that they can solve problems arising from industrial wastewater. With development of nowadays industrial wastewater treatment technology, it requires to be constructed to keep the teaching content up-to-date with current industrial wastewater treatment. Based on analysis of the current conditions of this course, it describes construction process, including revision of the teaching content, improvement of teaching methods and class mode, compiling of test database and exercise database.

The world is witness pollution of environment and depletion of resources with fast development of economy and growth of population. Mankind are facing the problems that the earth is revenging mankind for destroying the nature balance, which requires proper environmental management to maintain balance between economic development and environment. To cultivate graduates with knowledge on maintenance of balance between economy and environment, Environmental Economics and Management is offered to undergraduates whose major is Environmental Engineering. Due to development of environmental management, this course requires construction to keep class teaching up-to-date with current environmental economics and management. This paper firstly analyzes conditions of this course prior to construction, and then provides a construction plan in terms of revision of teaching content, improvement of teaching methods and class modes, compiling of exercise database and test paper database.

Promotion of cleaner technology could be aided by Environmental Management Systems (EMSs), in which business and industry can implement a system of self-regulation on their processes. Core idea of cleaner production is pollution prevention and processing, which is quite different in production modes with traditional production of final processing of pollution. The course cleaner production is offered to undergraduates majoring in Environmental Engineering to cultivate students familiar and special in idea and performance of cleaner production. To keep up with its development nowadays, it requires construction to develop teaching content, teaching methods, class mode and etc. which are more appropriate for the students. In this paper, conditions of this course prior to construction were described, and then a construction plan was given for improvement of teaching effect.
