Description
Technical field:
The present invention relates to a kind of waste disposal plant, be specifically related to a kind of board-like film film biochemical reactor based on particle scouring technology.
Background technology:
The film biochemical reactor is the biochemical reaction system that is combined with bio-reactor by membrane separation technique, in using, sewage treatment process usually formed by biological reaction tank and membrane cisterna, membrane cisterna replaces the second pond in the traditional activated sludge process, greatly improved the ability of system's solid-liquid separation, thereby system's effluent quality and volumetric loading all are greatly improved.
Difference according to the membrane module arrangement form, the film biochemical reactor is divided into two kinds of immersion and external placed types, submerged membrane biochemical reactor energy consumption is low, be widely used in municipal wastewater, particularly small-sized decentralized type sewage is processed in the engineering, the membrane module that the submerged membrane biochemical reactor is commonly used has two kinds of hollow fiber ultrafiltration membrane and plate-type hyperfiltration membranes, these two kinds of films respectively have relative merits, the hollow-fibre membrane low price, volume is high, but the film silk easily pollutes, and cleans trouble after polluting, and board-like film plot ratio is slightly high, price is slightly expensive, but no matter be the film biochemical reactor of hollow-fibre membrane or board-like film, film is easy to contaminated, all is the pollutent that the friction on film surface is washed away the film surface by air pocket generally, the effect of this cleaning film is not ideal enough, therefore uses pretty troublesome.
Summary of the invention:
The purpose of this invention is to provide a kind of board-like film film biochemical reactor based on particle scouring technology, it is simple in structure, and low price can self-cleaning internal membrane sheet devices, and cleaning performance is good, easy to use.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises scrub particle 1, membrane module framework 2, flat plate ultrafiltration diaphragm 3, micropore aeration pipe 4 and membrane cisterna 5, membrane cisterna 5 inside are provided with membrane module framework 2, membrane module framework 2 inside evenly are provided with several flat plate ultrafiltration diaphragms 3, and the inboard of membrane module framework 2 and outer lateral suspension are distributed with several scrub particles 1, and the below of flat plate ultrafiltration diaphragm 3 evenly is provided with several micropore aeration pipes 4.
Described scrub particle 1 is gel particle, adopts water to drive gel particle and constantly moves, and cleans membrane surface, reaches the effect of cleaning.
When the present invention used, there was pollution layer 3-1 on flat plate ultrafiltration diaphragm 3 surfaces, cleaned flat plate ultrafiltration diaphragm 3 surfaces by scrub particle 1, and pollution layer 3-1 is come off.
The present invention has following beneficial effect: it is simple in structure, and low price can self-cleaning internal membrane sheet devices, and cleaning performance is good, easy to use.
