Breeding sewage purification device based on biological membrane separation technology and cross-flow warm brushing

Abstract

The invention discloses a breeding sewage purification device based on a biological membrane separation technology and cross-flow warm brush. The device structurally comprises supporting vertical plates, a horizontal tank shell seat, a top cover arc groove shell, traction handle blocks, a biological membrane roller tank, a bearing disc frame tank and a three-phase electrifying groove. The biological membrane roller tank is matched with the bearing disc frame tank to a built-in separation overturning partition plate and a built-in cross flow bracket, so it is ensured that an electric heating transverse plate is inserted into heat and sterilize water; then the water is brushed in a sliding manner, so that the warm brushing operation forms coverage of paddling water with hot air flow, the pressure in the water is increased, organic impurities accumulated by a given mass form sinking operation to keep the dialysis performance of a biological membrane panel, avoid accumulation and avoid thewater level difference in order to achieve advection transition; and vertical air flow is formed for the biological membrane panel through an air blowing ladder groove for downward irrigation and scouring, so maintenance and turnover of the biological membrane surface are guaranteed, the filtering and purifying effects of aquaculture sewage are improved, and the stability of ecological sewage treatment is guaranteed.

Description

Technical field [0001] The invention is a breeding sewage purification equipment based on the cross-flow warm brush of the biofilm separation technology, and belongs to the field of biofilm separation. Background technique [0002] Most of the aquaculture wastewater is wastewater mixed with microorganisms, and it is also a water body with a high organic content. It is necessary to filter and clean the flocs in the water. At this time, the working efficiency of the biofilm is to separate and filter, and promote the accumulation and precipitation of organic impurities to ensure In the purification and purification of sewage, the disadvantages of the current technology to be optimized are: [0003] Aquaculture wastewater is often mixed with excreta such as fry manure. The use of biofilm to filter and precipitate is an ecological isolation operation for organic impurities, but the superimposed use of biofilms will cause the water flow to be less active in dialysis and have greater perm...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a breeding sewage purification equipment based on biofilm separation technology cross-flow warm brush, to solve the problem that aquaculture sewage is often mixed with excrement such as fish feces, and the use of biofilm to filter precipitation is Ecological isolation of organic impurities, but the superimposed use of biofilms will result in less fluid dialysis activity and greater permeability, and gradually allow organic impurities to block the slots and make it difficult for water to seep out and purify, resulting in a difference in water level in the inner pool, thus It directly causes the falling potential energy of the water body to impact the low surface and cause sputtering, causing the diaphragm to be deformed by the inertial impact of water droplets, causing the membrane surface to loosen and collapse for the next aquaculture sewage filtration, allowing organic impurities to penetrate through large gaps and interfere with the progress of water purification , resulting in the need for refluxing secondary filtration operations
