化工废水处理技术及其进展

Research Progress of the Chemical Wastewater Treatment Technology

我国水污染现象十分严重,工业废水处理达标率低。化工废水占据工业废水排放的较大部分,引进新技术对化工废水进行处理意义重大。化工废水中污染物种类繁多、水质变化大,处理困难。随着科技的发展,大量的新技术被引进到化工废水的处理中,对新兴的化工废水处理技术进行了综述,针对研发方向提出了建议。

The water pollution problem in China is very serious. Most of discharged wastewater cannot reach to the national standard. The wastewater from chemical industry occupies a large part of the industrial effluent. Therefore, developing new technology to treat the wastewater from chemical industry is very important. As the wastewater from chemical industry has many types of pollutants and unstable quality, so it is hard to treat chemical industry wastewater. With development of the science and technology, a lot of new technologies are introduced into the treatment of the wastewater from chemical industry. In this paper, some new technologies for chemical industry wastewater treatment were introduced, and suggestions for further development of chemical industry wastewater treatment technology were put forward.
