摘要
本文介绍了采用水解-气浮-接触氧化法对某草浆造纸废水原有废水处理工艺改造,经过一年多的运行监测,结果表明:处理后出水COD、BOD5、SS等各项指标均优于《造纸工业污染物排放标准》(GWPB2-1999)的要求。
This paper introduces the implication of hydrolysis - air floatation - bio-contact oxidation process to replace the former process for the treatment of wastewater generated from wheat straw pulping in a paper-making mill. It is shown that indexes {COD, BOD5 and SS） of the effluent are better than the demand of discharge standard, GWPB2-1999, through monitoring for over one-year＇s operation.
