The maintenance of sewage treatment equipment is an objective requirement for the movement of the equipment itself. The purpose of equipment maintenance is to promptly deal with a large number of common problems caused by changes in the technical status of the equipment during operation and to improve them at any time. The technical status of sewage treatment equipment ensures the normal operation of the equipment and extends the service life of the equipment. Equipment damage often leads to operation failure, so the wsz integrated sewage treatment equipment of the water treatment system needs to be regularly inspected, maintained and repaired. Operators should generally spend more than one-third of their working time on maintenance. For example, durable equipment such as grilles and gearboxes that are not damaged in time also need to be shut down regularly for thorough overhaul. All types of pumps need to be disassembled and cleaned regularly. Bearings should be checked and refueled regularly. The main sewage treatment equipment should have special cards to record the place of origin, price, operating status, number of repairs, maintenance personnel, etc.
