Description

Technical Field

[0001] The utility model relates to the technical field of cleaning wastewater treatment, and more specifically to cleaning wastewater treatment equipment. Background Art

[0002] Wastewater used in industrial production needs to be treated to meet the standards before it can be discharged. When treating cleaning wastewater with high COD (chemical oxygen demand) values, alkalinity, and high nitrogen and phosphorus pollutant content, the generally required process is to collect the cleaning wastewater, balance the water quality and quantity, and then lift it to the low-temperature evaporation equipment for evaporation treatment. The treated wastewater undergoes Fenton pretreatment to remove CDD in the wastewater. The pretreated wastewater undergoes reverse osmosis treatment, and finally the treated water undergoes low-temperature evaporation treatment, and the evaporated water is used for reuse.

[0003] When the Fontan reactor equipment cleans wastewater, it can generate hydroxyl radicals with strong oxidizing ability by using a chain reaction between divalent iron ions and hydrogen peroxide in the reactor. The oxidation potential of this hydroxyl radical is second only to fluorine, and it has extremely strong addition reaction characteristics, and can non-selectively oxidize most organic matter in the wastewater. It is used to treat industrial wastewater with high COD that is difficult to biodegrade or difficult for general chemical oxidation to work. After the Fontan reactor reacts with the cleaning wastewater, precipitated impurities will form at the bottom of the reaction tank after the reaction, and the precipitated impurities need to be cleaned regularly. However, it is not convenient to clean the impurities precipitated and accumulated at the bottom of the reaction tank. The staff needs to go down to the bottom of the reaction tank for manual cleaning, which is cumbersome. Therefore, a cleaning wastewater treatment equipment that can clean the precipitated impurities formed in the cleaning wastewater is needed.

[0004] In view of this, the utility model provides a cleaning wastewater treatment device. Utility Model Content

[0007] As a further improvement of the technical solution, a blocking plate for blocking impurities accumulated in the collecting frame is fixedly installed on the top of the collecting frame, and an air outlet mesh plate is installed on the top of the collecting frame.

[0008] As a further improvement of the present technical solution, the lifting assembly includes a fixed column fixedly installed on the top of the reaction pool body, a screw rod is rotatably installed inside the fixed column, a driving motor is installed on the top of the screw rod passing through the fixed column, and the outer surface of the screw rod is threadedly connected to a connecting plate fixedly connected to the top of the collection frame.
