Sewage treatment system with segmental ceramic membrane filters

Abstract

The invention discloses a sewage treatment system with segmental ceramic membrane filters. The sewage treatment system comprises a sewage tank, a clean water tank, a water pump and connecting pipelines. The sewage tank is connected with the water pump through the corresponding pipeline, the water pump is connected with one or more segmental ceramic membrane filters through the corresponding pipelines, and the segmental ceramic membrane filters are connected with the swage tank through the corresponding pipelines. The segmental ceramic membrane filters are formed by arranging ceramic membrane pipes in sealed shells, the two ends of each sealed shell serve as a sewage inlet and a sewage outlet respectively and are connected with the corresponding pipelines, and the sealed shells are provided with clean water outlets which are connected with the clean water tank through the corresponding pipelines. The adopted segmental ceramic membrane filters can effectively prevent overall breakage of ceramic membranes and are convenient to replace and maintain, and the sewage treatment system can be widely applied to sewage treatment of environmental sanitation vehicles, reduce clean water supplementing frequency, prolong the effective time of cleaning and sweeping work and lower maintenance cost.

Description

technical field [0001] The invention belongs to the technical field of special sanitation vehicles, and in particular relates to a sewage treatment system with a segmented ceramic membrane filter, which is mainly used for the sewage filtration and recovery work of sanitation cleaning and sweeping vehicles. Background technique [0002] With the wide application of road cleaning vehicles in the sanitation industry, how to improve the effective operating time of cleaning vehicles and reduce the purchase and use costs of cleaning vehicles per unit operating area has become a new research topic. At present, the sewage collected by conventional vehicles on the market after washing the road surface is generally discharged directly, which not only causes waste of water resources, but also needs to repeatedly go to the water station to fill with clean water and discharge sewage to the garbage station, which greatly limits cleaning. Effective operating time of the vehicle. Therefore...

AI Technical Summary

Problems solved by technology

The conventional filtration system currently used in the market is not only huge in size, seriously occupying the limited space of the cleaning vehicle, but also has low sewage treatment efficiency, and the filter screen is easily blocked and difficult to clean. It has the characteristics of short working cycle and high maintenance cost.

[0003] Since ceramics are brittle materials, especially when they are applied to cleaning vehicles, bumpy road conditions can easily cause damage to the ceramic membrane, which not only requires high maintenance costs but is also difficult to disassemble and maintain

[0004] The patent No. CN203899295U applied by Fujian Longma Environmental Sanitation Equipment Co., Ltd. is a "recycled water recycling device for washing and sweeping vehicles". Segmented filters, but in parallel mode, when working, one part of the filter is in the working state, and the other part of the filter is in the cleaning state, which cannot fully exert the maximum performance of the filter

Zoomlion’s patent No. CN102561241A “Control method, device and system for washing and sweeping vehicles” adopts the method of pumping out the air and water in the filtration membrane for pressure filtration. The biggest disadvantage of this filtration method is The pressure difference inside and outside the membrane is small, the filtration efficiency is low, and the filter membrane is easy to clog, difficult to clean, and difficult to maintain
