摘要
染料中间体二硝基氯化苯废水对生物具有毒性,是目前最难处理的废水之一,本研究采用铁屑-煤渣法对废水进行预处理,以改善它的可生化性,降低废水COD和色度。研究结果表明,经铁屑-煤渣处理之后,出水可生化性好,对生化过程无明显的抑制作用;同时废水COD和色度的去除率也很高。
Dyeing inteninediate dinitrotchlorobenzene is toxic for microorganism and is one of the most difficulty-treated watewater. A pretreatment method for improving the bio- logical treatability and removing the (30D and colorization using combined iron scrap-coal cin- der has been studied . The research results show that the effluents after pretreatment using iron scrap-coal cinder become hetter bindegradabi lity without obvious inhibition to biological process; on the other hand , the removal ratio of COD and colonization is also very high .
