工业废水污染控制方法的新进展

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。同时指出：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；研究开放高效、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。

New development of the industrial wastewater pollution control

The pollution of our environment is one of the biggest hazards that human beings face today. More wastewater resulting from the development of industry is discharged especially. If the wastewater is discharged directly or treated improperly, it can interfere with the self cleaning mechanism of water bodies, thus the water quality becomes permenently degraded. People are becoming increasingly aware of the problems posed by pollution, realizing the wastewater must be treated before discharging. The methods summarized in this paper can be applied to industrial wastewater treatment, including chemical processes, physiochemical processes and biological processes. Because of the complexity of wastewater, the treatment processes consists of a series of unit operation in order to meet the acceptable quality standards. It is not right to consider which types 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 wastewater.
