生物强化技术在废水治理中的应用研究

Study on the Application of Biological Technology in Wastewater Treatment

生物强化技术是为了提高废水处理系统的处理能力,而向该系统中投加从自然界中筛选的优势菌种或通过基因组合技术产生的高效菌种,以去除某一种或某一类有害物质的方法。这种处理方法通过微生物的新陈代谢作用,将废物分解、吸收,从而达到治理污染的目的。生物强化技术因能在不扩充现有的水处理设施基础上,提高其水处理的范围和能力,因此近年来在难降解、高毒性废水治理中的应用日益受到重视。

Biological enhancement technology is to increase the waste water processing and the processing capacity of the system, and to the system of investment and dominant strains screened from nature or produced by gene combination technology of high efficient strains to remove one or a kind of harmful substances. This treatment method through the metabolism of microorganisms, the waste decomposition,absorption, so as to achieve the purpose of pollution control. In recent years, the application of biological technology in the treatment of coking wastewater has been paid more and more attention because it can not expand the existing water treatment facilities and improve the scope and capacity of water treatment.
