摘　　要：该文考察了浅层气浮工艺除藻效能。结果表明浅层气浮工艺除藻的最佳工艺参数：PAC投加量为2～3mg／L，PAM投加量为0．1mg／L，溶气罐进口压力为0．30～0．4MPa，回流比为16％，水力负荷小于7．6m^3／m^2h，进气量大于0．2m^3／min。在此适宜工况下，除藻率大于80％。The effect of shallow dissolving air-floatation on algae removal was investigated in this paper. The results show the optimal conditions are as follows： dosage of PAC is 2 -3 mg/L, dosage of PAM is 0.1 mg/L, inlet pressure is 0.30 -0.4 MPa, reflux ratio is 16%, hydraulic loading is below 7.6 m^3/m^2 · h and inlet volume is above 0.2 m^3/min. Under such optimal condition, removal rate of algae is more than 80%.
