新型无机高分子絮凝剂对废水中的细菌除菌能力研究

STUDY ON REMOVAL ABILITY OF A NEW INORGANIC HIGH POLYMER COAGULANT TO BACTERIA IN WASTE WATER

本文介绍了一种新型无机高分子絮凝剂──硅钙复合型聚合氧化铝铁（SCPAFC）在含菌废水处理中的应用。结果表明，该产品对含菌废水的COD去除率为95％，浊度去除率在95％左右，同时对细菌去除率达到60％以上。最佳使用pH仅为7左右，最佳投药量为40mg／L，在该条件下处理效果优良。但在实际处理过程中需进一步做放大试验。

The article introduced the application of a new inorganic high Polymer coagu lant - Silicon-Calcium PolyAluminum-Ferric Chloride(SCPAFC)in treatment of waste water contained bacteria. The experimental results showthat the SCPAFC for waste water contained bacteria, the removal rates of the COD, the turbid degree and bacteriareached 95 %, 95% and 60% respectively. The best PH vaIue is 7,and the best amount of SCPAFC is 40mg/L,whichmakes the effect quite good. The auther indicates that it needs further amplification experiment in practical treatingprocess.
