    Yixing Equipment Technical Transformation

    release time:2020-03-16

    A domestic sewage treatment plant was built in 2017, and its design scale is 20,000 cubic meters per day. The post-standardization advanced treatment process is a high-efficiency sedimentation tank + fiber disc filter, using two Yixing equipment with a diameter of 2 meters each. 12 rounds of equipment. The equipment backwash system is paralyzed, the filter cloth has low water flux, the equipment is frequently backwashed, and is in an overflow state. After on-site inspection and maintenance, the equipment has the following problems: 1. The design of the backwash system is unreasonable, the filter disc and the suction port cannot be fully fitted, and the equipment has a poor backwash effect. 2. The equipment uses ordinary polyester filter cloth. The base cloth is dense, the fiber is crimped, and the flux and filter cloth regeneration performance are poor.

    In response to the above problems, our company signed a turntable filter overhaul contract with the water plant to comprehensively repair the equipment, rectify the backwash system, replace the filter cloth, and commission the whole machine. Iron anchor new filter cloth. The entire project is overhauled, the equipment backwash interval is longer, and the overall energy consumption is reduced, which effectively solves the problem for the owner.
