聚合氯化铝(PAC)和聚合氯化铁(PFC)对活性污泥的影响

Influence of Poly-aluminium Chloride and Poly-ferric Chloride on Activated Sludge

阐述了化学絮凝的反应机理 ,论述了在活性污泥污水处理系统中加入聚合氯化铝 (PAC)和聚合氯化铁 (PFC)絮凝剂后 ,对污水的生物处理系统有无影响 ,确定了影响范围 ,实验结果表明在一定的污泥浓度和pH值范围内 ,适当的絮凝剂投加量可以提高CODCr的去除率 ,为城市污水厂中水絮凝处理产生的污泥找到了出路。

The paper introduces the reactive mechanism of chemical flocculation.Main research focuses on the influence of the sewage trea- ting system by plunging into varies amount of polyaluminium chloride(PAC) and polyferric chloride(PFC) and the determination of influence range.The theoretic results confirm that administering proper amount of PAC and PFC can enhance the remove ratio of chemical oxygen demand ( COD ),thus finds an outlet of flocculent sludge for wastewater reuse.
