摘要
对缺氧变速生物滤池 (ABF)处理城市污水出水的混凝强化处理效果进行了试验研究。试验中选用聚合氯化铝 (PAC)、聚合硫酸铁 (PFS)、聚合硅酸铁 (PFSS)为絮凝剂 ,聚丙烯酰胺 (PAM )为助凝剂。结果表明 ,在不调整 pH的条件下 ,处理后的出水主要水质指标可达到国家《污水综合排放标准》(GB8978- 96 )
A jar test experimental study was conducted to improve the effect of anoxic velocity variable bio filter (ABF) treating municipal wastewater by coagulation enhancement measure. The poly aluminum chloride (PAC), poly ferric sulfate (PFS) and poly ferric sulfate silicate (PFSS) were used as coagulants and polyacrylamide (PAM) was dosed as coagulant aid into the wastewater. The results showed that under condition of no pH adjustment the quality of the effluent after coagulation was improved greatly and could meet the requirement of national wastewater discharge standard (GB8978 96).
