HPAM复配混凝剂处理生活污水的试验研究

摘要

The experiment was carried out in a residential area of domestic sewage outfall sewage coagulation pretreatment, the use of HPAM and PDM to reduce the subsequent processing load.The study found that has a certain effect on treatment of domestic sewage by two, but HPAM alone adding turbidity removal effect is not obvious, can again confirm the two combination is significantly better on the sewage treatment effect by microscopic observation of floc structure.This data provides a basis for the future use of coagulants.%试验通过对某居民小区生活污水排放口污水进行混凝预处理,采用HPAM与PDM联用以此减小后续工艺处理负荷.研究发现二者联用对生活污水具有一定处理效果,但HPAM单独投加时去浊效果不明显,通过显微镜观察絮体结构,可以再次印证二者联用对污水的处理效果更加明显.此数据为以后混凝剂复配使用提供了一定依据.
