佛山高明水厂单轨式水下刮泥机的应用与改进

Application and Improvement of Monorail Underwater Mud Scraper in Gaoming Water Treatment Plant

佛山高明水厂三期沉淀池采用单轨式水下刮泥机。实际运行效果表明,与虹吸排泥车相比,单轨式刮泥机的排泥水含固量提高了4~10倍,排泥水含量大大减小,且排泥过程中对沉淀池中水流扰动小,排泥彻底,无死角。针对单轨式刮泥机在运行中存在的问题,对其结构进行了改造,对其电气和控制系统进行了升级,改进后的单轨式刮泥机整体运行效果得到了提升,而且操作、维护和管理更方便。

Monorail underwater mud scraper （MUMS） was applied in sedimentation tank of the third-phase project in Gaoming Water Treatment Plant. The operation results showed that the solid content in muddy water produced by MUMS increased by 4 to 10 times compared with that produced by siphon mud machine （SMM）, and the muddy water was reduced greatly. MUMS showed small flow disturbance in the sedimentation tank when draining muddy water, and could dredge mud thoroughly without dead angle. In order to solve the problems in the operation of MUMS, the structure was reformed, and the electrical and control systems were upgraded. The operation effect of the improved MUMS system was improved. The operation, maintenance and management of the improved MUMS system became more convenient than SMM.
