水库水处理效果分析

Analysis on Treatment Effect of Reservoir Water by Integrated Flotation and Sedimentation Unit

研究了XX市某水厂新型气浮-沉淀工艺对水库水处理效果。通过改变PAC投加量和进水量负荷来确定各个影响因素的最优值,考察工艺运行效果。运行气浮工艺时,最适PAC投加量及进水量范围分别为1.5 mg/L、和210~270 m^3/h。运行沉淀工艺时,最适PAC投加量和进水量范围分别为5.0~5.4mg/L和180~270 m^3/h。新型气浮-沉淀工艺可提高不同季节水库水出水效果。

The treatment effect of reservoir water by integrated flotation and sedimentation unit（IFSU） was studied. Through changing the PAC dosage and the inflow load, the optimal values of every influence factors were determined. The results showed that, when running DAF, optimum PAC dosage and inflow load were 1.5 mg/L and 210-270 m^3/h,respectively; When running sedimentation process, optimum PAC dosage and inflow load were 5.0-5.4 mg/L and 180 -270 m^3/h, respectively. The test result proved that SFIPS can be used to treat reservoir water in different seasons.
