摘　　要：为回收利用校园洗浴废水,选用不同的混凝剂,通过六联搅拌器进行搅拌,对洗浴废水浊度和色度的去除进行了试验研究。通过试验得出:在试验条件下三氯化铁混凝效果最好,其矶花形成快,絮体稳定,沉降迅速。当投加量为14 mg/L时,浊度去除率为92.76%,色度去除率为93.33%;当投加量为18 mg/L时,浊度去除率为95.54%,色度去除率达到97.78%,能够满足回用水浊度和色度的指标要求。in order to recover and utilize the campus bathing wastewater,different coagulants were selected and stirred by six connected aaitators to remove the turbidity of the bathing wastewater.The results show that the coagulation effect of ferric chloride is the best under the test conditions,with fast alum formation,stable floc,rapid sedimentation.When the dosage is 14 mg/L,the turbidity removai rate is 92.76%,and the color removai rate is 93.33%;when the dosaae is 18 mg/L,the turbidity removal rate is 95.54%,and the color removal rate is 97.78%.It meets the requirements of turbidith and chroma of reuse water.
