摘　　要：针对温州某供水厂原有平流沉淀池沉淀效果较差,双阀滤池过滤周期短、反冲洗效果不佳,出水浊度不能满足要求等问题,进行了技术改造。在平流沉淀池内增设侧向流斜板沉淀,将双阀滤池改造为整体滤板小阻力长柄滤头配水、石英砂均质滤料、气水反冲洗滤池,并完善了滤池的自动控制系统。运行结果表明,改造后沉淀池出水浊度大大降低,滤池出水水质提高,反冲洗效果明显改善。Technical renovation was conducted to solve the problems occurring in a waterworks in Wenzhou City, such as poor sedimentation effect in original horizontal flow sedimentation tank, short filtration cycle and poor backwash efficiency of dual valve filter and high filtrated water turbidity. The lateral flow inclined plate was added in the horizontal flow sedimentation tank. Besides, the small resistance filter plate and long-handled filter head distribution system was installed in the original double valve filter, the uniform silica sand media and the air-water backwash system were utilized, and the automatic control system was perfected. The operational results showed that after renovation, the treated water turbidity of the sedimentation tank was significantly reduced, the filtrated water quality and backwash efficiency of the filter were improved.
