焦化废水的强化处理技术

Intensification Technology of Coking Wastewater Treatment

焦化废水成分复杂,含有毒难降解有机物种类多、浓度高采用普通活性污泥法处理焦化废水,出水很难达到国家排放标准。提出利用生物强化技术对活性污泥工艺进行强化,提高焦化废水中难降解有机物的可生化性与可处理性。

There are many toxic and non-degradable organic matters in coking wastewater. Their compositions are very complex and have high concentrations. Most coking plants presently use common activated sludge process to treat coking wastewaters. Water quality in effluent doesn't meet nation's discharge criterion. To let COD in effluent of coking wastewater biologic treatment discharge under criterion, this paper puts forward that activated sludge process can be intensified by biologic intensification technology. This technology can raise biochemicalablity and treatablity of non-degradable organic matters in coking wastewaters.
