摘要：

环境污染是当今人类面临最大的危害之一,特别是工业生产的发展,排出了大量的废水,这些废水如直接排放或处理不当,将影响水体的自净,因而使水质恶化。人们日益意识到环境污染带来的危害,现在污水必须通过处理才能排放已成为人们的共识。本文概括了应用于工业废水处理的化学法、物理化学法和生物法的一般原理和最新进展,由于废水的组成复杂,往往需要由几种方法组成一个处理系统,才能完成所要求的处理功能,因此指出不能认为某种方法是最好的,最先进的。同时提出 :尽管化学方法有其自身的缺点,但在某些方面仍然有不可替代的作用 ;研究开发高效、经济的应用于工业废水处理新技术已成为环保工作者的热点。

Abstract:

The pollution of our environment is one of the biggest hazards that human being s face today.More wastewater result ing f rom the development of indust ry is discharged especially.If the w astew ater is discharged direct ly or treated improperly, it can interfere w ith the self-cleaning mechanism of water bodies, thus the water quality becomes permenently deg raded.People are becoming increasing ly aw are of the problems posed by pollution, realizing the w astew ater must be t reated befo re discharging.The methods summarized in this paper can be applied to industrial w astew ater t reatment, including chemical processes, phy siochemical processes and biological processes.Because of the complex ity of wastewater, the treatment processes consists of a series of unit operat ion in order to meet the acceptable quality standards.It is not right to consider w hich ty pes are the best or the most advanced.Although the chemical processes have their shortcomings, other processes cannot substitute them in some aspects.One of the environmentalists' pursuits is to develop the new, highly effective and economic technology applied to industrial w astew ater.

Key words: industrial w astew ater treatment, chemical processes, physic-chemical processes, biological processes
