| 摘 要： | 通过混凝试验考察不同配比的混凝剂聚合氯化铝(PAC)和硫酸铝(AS)对王小郢污水厂二沉池出水中磷的去除效果,同时研究了在固定配比下不同投加量对磷的去除效果。结果表明,最后得PAC 30%+AS 70%为最佳投药配比。当原水总磷质量浓度低于0.8 mg/L时,保证出水中TP的质量浓度低于0.2 mg/L的最佳投药量为6 mg/L;当进水中TP的质量浓度为0.8～1.25 mg/L时,最佳投药量为8 mg/L;若进水TP质量浓度为1.3～1.5 mg/L时,最佳投药量即为10 mg/L。 |

| Abstract: | Phosphorus removal by coagulation with different proportion PAC and AS has been studied.The effluent of Wang xiaoyin Wastewater Treatment Plant secondary sedimentation tank is for raw water.Then Phosphorus removal at same proportion PAC and AS with different dosage has been studied.In the end we get the best strategy PAC 30%,AS 70%.PAC and AS are used to do the best dosage of the trial,when the TP of raw water is under 0.8 mg/L,the best dosage is the 6 mg/L,to ensure that the water TP <0.2 mg/L range of fluctuation;when TP is 0.8～1.25 mg/L,the best dosage is 8 mg/L;when TP >1.3 mg/L,the best dosage is 10 mg/L. |
