Abstract
分别向按A/O方式运行的Sbr反应器中投加一定量氯化铁、硫酸铝、聚合氯化铝,考察这3种金属盐混凝剂强化活性污泥系统处理生活污水的效果。结果表明,这3种混凝剂的化学辅助除磷效果较好,其中,在100Mg/l(以进水量计)的投加量下,投加氯化铁和硫酸铝的强化处理系统对TP的平均去除率比空白组分别提高了65.52%和69.95%。对有机物的去除也有一定强化作用,对氮的强化处理效果不明显,但可提高活性污泥沉降性能。
 
Based on the SBR reactor running with the A/O process,the effect of enhancing activated sludge system adding coagulants(ferric chloride,aluminum sulfate and poly-aluminum chloride)on treating domestic sewage has been studied.Results showed that the three coagulants were efficient in chemical-aid phosphorus removal.The groups separately adding ferric chloride and aluminum sulfate in dose of 100 mg/L(in influent)gained the additional average removal rates of TP about 65.52% and 69.95%.The three coagulants also strengthened the removal of organic matter and had no great influence on the removal of nitrogen,but could improve the performance of sludge settlement.
