摘　　要：混凝效果在整个自来水生产工艺中至关重要,出厂水铝的控制逐渐成为研究重点。为指导实际生产,采用正交试验,研究混凝试验过程中混凝剂总投量、铁铝混凝剂投加比例、聚氯化铝(PAC)盐基度、pH等因素对混凝后出水浊度及余铝的影响。结果表明:铁铝混配试验组余浊指标的影响因素顺序为混凝剂总投量>PAC盐基度>铁铝混凝剂投加比例,余铝指标的影响因素顺序为PAC盐基度>铁铝混凝剂投加比例>混凝剂总投量;单铝运行试验组余浊指标影响因素顺序为PAC盐基度>PAC投量>pH,余铝指标影响因素顺序为PAC盐基度>pH>PAC投量。The coagulation effect is crucial in the entire production process of tap water,and the control of aluminum in the factory water is increasingly becoming a research focus.In order to guide actual production,orthogonal experiments were used to study the effects of factors such as the total dosage of coagulant,the proportion of iron aluminum coagulant,the basicity of polyaluminum chloride,pH,etc.on the turbidity and residual aluminum of the coagulated effluent during the coagulation test process.The results show that the main and secondary order of factors affecting the residual turbidity index in the iron aluminum mixed test group is total dosage of chemicals>basicity>iron aluminum ratio.The main and secondary order of factors affecting the residual aluminum index is basicity>iron aluminum ratio>total dosage of chemicals.The main and secondary order of factors affecting the residual turbidity index in the single aluminum operation test group is salinity>PAC dosage>pH.The main and secondary order of factors affecting the residual aluminum index is salinity>pH>PAC dosage.
