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。
The phase III sedimentation tank of Foshan Gaoming Water Plant adopts a monorail underwater scraper. The actual operation results show that compared with siphon and mud dump trucks, the sludge solids content of the monorail scraper increases by 4 to 10 times, the sludge water content is greatly reduced, and the disturbance of the water flow in the sedimentation tank during the mud discharge process is small. The mud is completely drained and there are no dead ends. Concerning the problems existing in the operation of the monorail scraper, its structure was modified and its electrical and control systems were upgraded. The overall operation effect of the improved monorail scraper was improved, and its operation and maintenance were improved. Management is more convenient.
