摘要:

焦化废水是一种氨氮和有机物浓度较高的难生化降解有机废水。系统地介绍了国内外近年来在焦化废水处理方面的研究进展。生物强化技术可以在原有设施基础上提高处理范围和处理能力,比较适合我国焦化废水处理的现状 ;固定化微生物技术、生物脱氮技术及生物流化床技术对传统生化处理技术进行了有效的改进,在焦化废水处理中将有良好的应用前景 ;与生化技术相比,化学技术的工艺简单、反应速度快、净化率高,但缺点是投资与处理费用较高。

Abstract:

Waste water from coke plants is a kind of ref ractory organic one with high concent ration of ammonia and organisms.Advances in coke plant wastew ater treatment in recent years in China and overseas are systemat ically introduced.Bioaugmentat ion technique can greatly increase the treatment applicability and capability of the existing treatment equipment and is more suitable for wastew ater treatment of the coke plants in China.Biological fluidized bed technique, immobilized technique and ammonia removal by biological method have made great improvements over traditional biological method and will find wider applications to the treatment of wastewater from coke plants.Compared with biological methods, chemical methods are simpler in treatment process, higher in reaction rate and removal ef ficiency.However, the investment and treatment cost of the chemical methods are higher than those of the former.

Key words: coke plant waste water, biological treatment method, chemical treatment method, advancements
