Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a multi-tank shared intelligent wastewater recycling system. Background Technology

[0002] The pretreatment of plastic parts is divided into pre-degreasing, degreasing, water washing, second water washing, and pure water washing spray stations according to different workstations. Separate tanks and related spray pipeline circulation systems are set up, and water pumps draw liquid from the lower tank for workpiece cleaning. The cleaned water flows into the lower water tank. During production, wastewater is continuously discharged into the line's collection pit. When the water level in the collection pit rises, it is automatically discharged to the wastewater treatment plant by a sewage pump. Existing technologies suffer from significant energy waste and high fresh water consumption. Traditional pipeline mixing and reuse causes cross-contamination of water quality, and membrane treatment systems are prone to scaling (silicate deposition leads to a reduction in membrane flux of over 60%). Existing technologies, such as the multi-tank centralized wastewater treatment system disclosed in prior art document CN110127768A, suffer from unstable recycled water quality (COD fluctuation ±30%) and low automation.
