高效生化反应器处理焦化废水研究进展

A Study on High Efficient Bio-reactor treating coke wastewater

焦化污水是在煤的高温干馏、煤气净化以及化工产品精制过程中所产生的废水,是一种含高氨氮、高有机污染物、难处理的工业废水,因此焦化废水的处理一直是国内外废水处理的一个难点。本文把焦点集中在处理焦化废水的生化反应器上,对传统反应器概况作了简述,并介绍了新型反应器和传统反应器的改进在焦化废水处理中的应用。

Coke-plant wastewater comes from high-temperature pyrolysis, coal-gas purification and the refining process of chemical product. It is a sort of industry wastewater which contains high concentration of NH3-N ,organic pollutants and other hard-removal matters. So the treatment of coke-plant wastewater is always a difficult topic either in china or in other country. This article mainly focuses on the bio-reactor which is used in the coke-plant wastewater treatment. Introductions of traditional bio-reactor are given out . Besides, the improvement of traditional bio-reactor and new type bio-reactor used in the filed are also introduced.
