tailieunhanh - Hazardous Industrial Waste Treatment - Chapter 5

Chúng tôi đang chứng kiến sự phát triển của một thế giới hoàn toàn công nghiệp, sản xuất công nghiệp toàn cầu, thị trường toàn cầu, viễn thông toàn cầu, vận chuyển toàn cầu, và sự thịnh vượng toàn cầu. Khách hàng tiềm năng này mang lại với việc thực hiện mô hình hiện tại của công nghiệp sẽ không đủ để duy trì tăng trưởng môi trường an toàn và do đó cần cải thiện mạnh mẽ. Là rất cấp thiết là một phương pháp tiếp cận hệ thống quản lý hoàn toàn với nền văn minh hiện đại. | 5 Pollution Prevention J. Paul Chen National University of Singapore Singapore Thomas T.

INTRODUCTION We are witnessing the evolution of a fully industrialized world with global industrial production global markets global telecommunication global transportation and global prosperity. This prospect brings with it the realization that current patterns of industrialization will not be adequate to sustain environmentally safe growth and therefore needs drastic improvement. What is urgently needed is a total management systems approach to modern civilization by focusing on pollution prevention activities as the first step. In the past pollution control by media-specific control technologies has improved environmental quality to a certain extent. Generally however it not only fails to eliminate pollutants but waste treatment processes have produced a large amount of sludge and residue that require further treatment prior to disposal so that they will not create secondary pollution. Waste treatment systems require investment in design installation operation and maintenance but these systems contribute no financial benefit to the industrial production. Pollution control technologies may also transfer pollutants from one environmental medium air water or land to another causing potential secondary pollution problems that require further treatment and disposal. Pollution control technologies address only short-term problems rather than eliminate pollutants. Costs of pollution control cleanup and liability have risen every year as have the costs of resource inputs energy and raw materials. Through many years of research we are beginning to understand the complexities of pollution management problems 1-10 . Some .
