摘要
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。
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.
