摘要
磷的生物法去除很难达到污水排放标准,通常要结合化学絮凝的方法。因此,试验采用氯化钙、硅酸钠、聚丙烯酰胺对含磷废水进行处理,考察了氯化钙投加量、硅酸钠投加量、溶液pH值等因素对除磷效果的影响。结果表明,在一定条件下,磷去除效果较好,去除率可达99%。
Biological process of phosphorus removal from wastewater can hardly satisfy the national regulation, so such water still needed chemical precipitation. The treatment of wastewater containing phosphorous by CaC12, Na2SiO3 and PAM was studied. The effects of CaCI2 dose, Na2 SiO3 dose and pH value on phosphorus removal were investigated. The results showed that the removal rate reached 99% under some conditions.
