摘要：焦化厂废水中酚、氰浓度较高，如直接排放会对环境造成一定的污染。本设计则以应用活性污泥法为主体处理这类高浓度含酚废水。利用微生物的新陈代谢来降解废水中酚等生物可降解的物质。废水经过除油、生化作用、沉淀作用和沸石吸附等过程的处理，从而使出水达到工业排放的标准。60021

本设计主要内容包括：工艺流程的选择，主要构筑物的选型与设计计算，处理站构筑物的安排及管路计算，部分辅助构筑物。

另外，本设计还对国内外焦化废水处理技术及活性污泥的有关知识做了阐述。

Abstract:：The phenol wastewater from coring factory is always of high concentration . It will cause a lot of pollution without treatment. In this design, the activated sludge is used to treat this kind of high concentration of phenol wastewater. The concentration of phenol and other biodegradable organisms are degraded by microbial metabolism. After the waste water is disposed by the process of oil bas removal. Biochemical action, coagulate precipitation, the zeolite adsorption column and so on, the quality of effluent can meet the emission control regulations of those industry wastewater.

The design includes: selection of technological process, the type choosing and calculation of the main parts of the plant, plane arrangement and pipe calculation of the treatment station, design of the supplementary parts of the plant, estimation of economy of the plant etc.

Moreover, the domestic and international relevant knowledge with the phenol wastewater processing technique and live and dirty mires are also expatiated in this article.

Keywords: waste water with phenol, the activated sludge system, A/O secondary biological treatment system, the zeolite adsorption column
