污泥循环在低浊微污染源水水质处理中的影响

The Effection of Sludge Circulating in Processing the Micro-polluted Source Water with Low Turbidity

高密度澄清池处理水质工艺利用污泥循环加速絮凝能力,具有占地面积小,处理效率高等优势,但在运行过程中发现出口水质恶化现象,文章通过对污泥循环系统的研究,发现低浊微污染源水水质处理过程中,循环的污泥在高温季节会对水质产生二次污染,经过实验,采取预氯化和粉末活性炭联合使用的工艺可有效保证水质安全,并用于生产,效果显著。

The effection of s I u d g e circulating in high-density clarifier on water quality was anylyzed in the paper in processing the micro-polluted source water with low turbidity, and the experiment results indicated that the utility of prechlorination and PAC had valuable effect and could ensure the water security.
