【摘要】：新型气浮—沉淀工艺是给水处理的新型组合工艺之一,珠海三灶水厂(2×10~4m~3/d)的改造工程采用了该工艺。在水厂调试运行过程中,新型气浮—沉淀池切换运行气浮或沉淀工艺,分析了其出水水质。结果表明,在原水高浊度情况下,沉淀+过滤工艺的出水浊度稳定在0.5NTU以下;在原水低浊度、高铁浓度或高藻类的情况下,气浮工艺较沉淀工艺出水水质好,气浮出水浊度绝大部分稳定在0.5 NTU以下、铁稳定在0.05 mg/L以下、藻类数稳定在3×10~5个/L以下;而在原水高锰浓度(0.1 mg/L)情况下,运行气浮工艺和沉淀工艺出水效果都不理想,但后续的锰砂滤池可以有效去除多余的铁、锰。
[Abstract]:The new air floatation-sedimentation process is one of the new combined processes for water supply treatment, which has been adopted in the revamping project of 2 脳 10 ~ 4 m ~ (3 / d) of Zhuhai Sanzao Waterworks. During the commissioning and operation of the water plant, a new type of air floating-sedimentation tank was used to switch the operation air floatation or sedimentation process, and the effluent quality was analyzed. The results show that under the condition of high turbidity of raw water, the turbidity of effluent of precipitation filtration process is below 0.5NTU, and that of air floatation process is better than that of sedimentation process when the turbidity of raw water is low, the concentration of high iron or algae is high. Most of the turbidity of air floatation effluent is below 0. 5 NTU, iron is below 0. 05 mg/L, algae number is below 3 脳 10 ~ 5 / L, but under the condition of high manganese concentration of raw water (0. 1 mg / L), the effluent effect of air flotation process and precipitation process is not ideal. But the subsequent manganese sand filter can effectively remove excess iron and manganese.
