Problems solved by technology

Laundry wastewater from large laundries is often doped with a lot of garbage (such as leftovers in clothing pockets, rags, knitted fibers, etc.), which will easily cause siltation after entering the pipeline with the wastewater, which is not easy to degrade, resulting in pipeline blockage and wastewater overflow. Increasing the difficulty of maintenance and polluting the environment

Abstract

The invention discloses a multi-stage filter tank for drainage pretreatment of a large laundry room. The multi-stage filter tank is suitable for gravity drainage and mechanical lifting drainage. According to the invention, a stainless steel sewage interception hanging basket is hung on a tank wall via a hook and can be regularly taken down for cleaning or replacement, so garbage and sundries doped in drainage of the large laundry room are intercepted and filtered, solid impurities are effectively reduced, the quality of discharged water is optimized, blockage and pollution of the impurities to a municipal sewage pipe network are reduced, and the environment is protected; and the multi-stage filter tank is suitable for various environments such as hotels, hospitals, nursing homes, dormitories and bath centers and worthy of wide popularization.

Description

Technical field [0001] The present invention relates to the field of sewage treatment, and specifically, a multi-stage filtering pool for a large laundry room drainage pretreatment. Background technique [0002] The filtration pool refers to a water treatment structure of the raw water or wastewater by filter media to remove suspended insoluble substances in the solution. It is often divided into two types of gravity filtration pools that flow downward, and two types of pressure-type filters, and the work cycle generally includes two processes for filtration and anti-flush. The filtration is often used in the water treatment and wastewater treatment after precipitation, and is also used in depth treatment of water. Large laundry room laundry wastewater is often doped with many garbage debriss (such as legs in the pocket, the buckle, knitting fiber, etc.) Increased maintenance difficulty, polluting the environment. Therefore, a multi-level filtration pool for a large laundry room ...
