摘要
皮革废水经物化和普通接触氧化处理后往往因为氨氮高而难以达标排放,本文探讨了采用曝气生物滤池(BAF)进一步降解经物化和普通接触氧化后出水中氨氮污染物的可行性及处理效果.研究结果表明,在BAF进水CODcr为200～250 mg·L-1、氨氮为80～100 mg·L-1时,经BAF曝气4 h处理后出水的CODcr和氨氮分别达到86 mg·L-1、10 mg·L-1以下.
In this paper, effluent ammonium of tannery waste can not reach the discharge standard after secondary treatments, its biodegradation possibility and effect of removal by biological aerated filters (BAF) were discussed. The results show that, when the COD crof the waste water of secondary treatments, the mass concentration of ammonium are respectively 200～250 mg·L -1,80～120 mg·L -1,the BAF process(4h) can help decrease the corresponding values of the effluent by less 86 mg·L -1and 10 mg·L -1.
