碱度对混凝效果影响及调节方式浅析——以铝系混凝剂为例

Analysis of the Influence of Alkalinity on the Coagulation Effect and Its Adjustment——Taking Aluminum Coagulant as the Example

混凝是净水工艺的重要环节,对提高污水处理厂出水水质有重要意义。碱度是影响铝盐混凝剂混凝效果和出水余铝含量的重要因素,合理的碱度调节方式可以在提高混凝效果、减少出水余铝的同时节省经济成本,为实际的工程应用提供参考。

Coagulation is an important part of the water purification process,which is of great significance for improving the quality of effluent water from sewage treatment plants.Alkalinity is an important factor affecting the coagulation effect of aluminum salt coagulant and the residual aluminum content in the effluent.The reasonable alkalinity adjustment method can improve the coagulation effect and reduce the residual aluminum in the water,and save economic costs,and it also can provide some reference for practical engineering applications.
