Description

Technical Field

[0001] The utility model relates to the technical field of industrial wastewater treatment, in particular to an automatic wastewater collection system. Background Art

[0002] Industrial wastewater generated in the production of general chemical enterprises may contain high-concentration organic pollutants and high-concentration ammonia wastewater and phosphorus wastewater. Usually, the main treatment method for single high-ammonia wastewater is physical and chemical method, including stripping, ion exchange, chemical precipitation, membrane separation, etc. However, the ammonia nitrogen in the effluent of physical and chemical method generally cannot meet the discharge standards, and further biochemical treatment is required to ensure that the treatment meets the discharge standards. Phosphorus wastewater is generally divided into biochemical method and chemical method. The biochemical method is mainly used for low-concentration organic phosphorus wastewater, and the chemical method is mainly used for high-concentration inorganic phosphorus wastewater. The high-concentration wastewater of chemical enterprises, when high ammonia or high phosphorus exists, usually affects the treatment effect of its organic pollutants, so the ammonia or phosphorus concentration will be reduced to a lower level before the next step of wastewater treatment. The first step in the treatment process includes: first, after mixing high-ammonia and high-phosphorus wastewater in proportion, adding a certain amount of magnesium salt, and controlling the pH to form struvite (magnesium ammonium phosphate) precipitation to remove most of the ammonia nitrogen and orthophosphate contained in the wastewater. Magnesium ammonium phosphate is an excellent slow-release fertilizer in agricultural production. Therefore, the struvite precipitate can be recycled and sold to phosphate fertilizer manufacturers, generating economic benefits and reducing sewage treatment costs.

[0003] The patent document with announcement number: CN217708920U discloses "a high-ammonia and high-phosphorus industrial wastewater pretreatment system", which involves driving a reciprocating screw in a cleaning frame to rotate by a motor, thereby causing a movable block on the outside of the reciprocating screw to reciprocate in the cleaning frame, and cleaning the struvite precipitates at the bottom of the sedimentation reaction tank by a scraper at the bottom of the movable block. During the movement of the movable block, the gear plate on the outside engages with the gear rail on the outside of the cleaning frame to rotate the rotating shaft, and cleaning the struvite precipitates on the inner wall of the sedimentation reaction tank by a cleaning plate and bristles on the outside of the rotating shaft.

[0004] Although the device achieves the purpose of cleaning struvite, it continuously pushes the struvite into the slag discharge pipe, which easily causes accumulation, thereby causing the slag discharge pipe to become blocked, which is not conducive to use. Therefore, it is necessary to provide an automated wastewater collection system that is easy to discharge to solve the above technical problems. Utility Model Content
