Integrated water treatment equipment combining bio-membrane with electric filter and water treatment process

Abstract

The invention provides an integrated water treatment equipment combining a bio-membrane with an electric filter. The integrated water treatment equipment comprises a sewage regulation chamber, a bio-membrane method sewage treatment chamber and an electric filtration treatment chamber, wherein a screen mesh is respectively arranged at a water inlet and a water outlet of the sewage regulation chamber; bio-membrane fillers are laid in the bio-membrane method sewage treatment chamber; an aeration head is laid at the bottom of the bio-membrane method sewage treatment chamber; multiple sets of electric filtration devices arranged in parallel are arranged in the electric filtration treatment chamber; an inclined flow mud fender is arranged at the water inlet of each set of the electric filtration device; a micron reticulated ruthenium titanium anode and a stainless steel microporous cathode are arranged in each set of the electric filtration device. The integrated water treatment equipment provided by the invention removes pollutants with a bio-membrane method; the membrane method has characteristics of relatively large biomass, long sludge age and less residual sludge; the electric filtration treatment chamber is mainly used for sludge-water separation; each electric filtration device is composed of a microporous anode and cathode, and has effects of filtration, gas electrolysis self-cleaning, microorganism killing and the like after application of voltage.

Description

Technical field [0001] The invention relates to a water treatment process suitable for the treatment of rural dispersed sewage and urban black and odorous water bodies, and specifically mainly integrates biological membranes, electric filtration, and auxiliary units including power, energy storage and pretreatment. Background technique [0002] The integrated sewage treatment equipment integrates the grid, primary sedimentation tank, biochemical tank and secondary sedimentation tank into one equipment. The integrated equipment has been assembled and debugged as a whole in the factory, with a small amount of on-site construction and flexible deployment. It is mainly suitable for sewage treatment in rural towns, residential areas, schools, and large shopping malls. However, the traditional secondary sedimentation tank uses the sedimentation properties of particulates to achieve mud-water separation, and its residence time is longer and the tank body is larger. Therefore, more integ...

Problems solved by technology

However, the traditional secondary sedimentation tank uses the sedimentation of particles to separate mud and water. Its residence time is longer and the tank volume is larger. Therefore, more integrated equipment currently uses membrane methods to improve the separation efficiency of mud and water, that is, membrane bioreactors. (bio-membrane reactor, BMR), reduce the size of the integrated equipment, and improve the water quality at the same time

However, when the membrane bioreactor treats
