摘要
根据某印染废水的特点 ,在原有传统处理工艺的基础上进行了工艺改造 ,将调节池改为水解酸化池 ,将活性污泥曝气池改为接触氧化池 ,在池内形成了合理的微生物分布 ,大大地改善了出水水质 ,使 COD、SS、硫化物、色度的去除率分别提高了 2 2 %、10 %、36 .4%、2 5 %。既满足废水排放标准 ,又节约了土建资金。
A traditional printing and dyeing wastewater treatment process was improved.The regulation tank was changed into the hydrolysis acidification tank and the aeration tank was changed into contact oxidation tank,in which the different function of micro bacteria was formed along the vertical of the aeration tank.The removal ratios of COD、SS、S 2- and chromaticity were increased 22%、10%、36.4% and 25% respectively,which fit the discharge standard.
