降低焦化废水总氰浓度的方法

摘要

This paper introduces the three methods of reducing total cyanide concentration in coke plant wastewater. The test shows that the methods of coke absorption and flocculant dosing to oil re-moval tank are both effective. Coke absorption method will increase labor intensity,so it is not a good option;while the method of dosing flocculant to oil removal tank with self-pressure blowdown system could not only reduce the total cyanide concentration and also benefit the biochemical treatment process.%介绍了降低焦化废水总氰浓度的3种方法。试验表明，采用焦炭吸附和在除油池投加絮凝剂的方法都是有效的。焦炭吸附法会增加劳动强度，不宜采用；在有自压式排污系统的除油池内投加絮凝剂，不但降低了总氰浓度，而且有利于生化处理工序。
