Description

TECHNICAL FIELD

[0001] The utility model relates to wastewater treatment technical field, concretely is a scouring waste water pretreatment device. BACKGROUND

[0002] The main source of scouring industrial wastewater is the wastewater produced in the scouring process of wool spinning enterprises. A large amount of water is used to clean wool in the scouring process, and impurities such as lanolin, sheep sweat, sheep manure, grass clippings, short hair and silt are mixed in the cleaning water, forming high-concentration organic sewage. If the floating matter, meat and wool in the wastewater are not treated before entering the subsequent treatment process, the booster pump will be blocked and a large amount of wool will accumulate in the adjusting tank, which will seriously affect the normal operation of the sewage treatment system. Therefore, a pretreatment device must be provided before the wastewater enters the adjusting tank. In recent years, some scouring factories and design and research units in China have carried out a lot of experimental research on the treatment of scouring wastewater, and have achieved some research results, but there is still a lack of ideal treatment scheme for popularization in actual production.

[0003] The most commonly used solution at present is to set a grid before the wastewater enters the adjusting tank to intercept the suspended solids and floating matter in the wastewater to ensure the normal operation of the subsequent treatment process. This method can effectively remove suspended solids and floating matter in wastewater, but animal hair in wastewater can still pass through the grid gap and cannot be effectively removed. If a smaller grid gap is set to block the hair, it is easy to cause the grid gap to be blocked and affect the filtration.

[0004] Therefore, it is necessary to provide a scouring wastewater pretreatment device to solve the above problems. CONTENT OF THE UTILITY MODEL
