Description
Technical field
The present invention relates to a kind of circulating filtration sewage water treatment method capable of washing.
Background technology
At present, the water pollution being on the rise not only reduces the use function of water body, has been further exacerbated by shortage of water resources
Contradiction, the strategy of sustainable development that China is implementing is brought and had a strong impact on, but also seriously threatens city dweller
Safe drinking water and the people health.Substantial amounts of sewage is needed badly carries out processing recovery by effectively processing method.
Carrying out processing to sewage by the method for permeation filtration has high treating effect, can automate continuous operation, not shadow
The advantages of ringing the water quality of product water, is used widely in sewage-treatment plant at home.But it penetrates filter membrane and is using one
Section time caudacoria surface can be contaminated causing Pore Blocking, and the permeability rate of film declines.And the contamination and plugging of film mainly due to
Film surface impurity accumulate and the growing of microorganism caused by.Wherein microbial growth is not merely blocked by film, but also can have to film
Erosion damage is acted on.If these pollutants on film surface periodically remove the destruction that will result in film unrepairable not in time, and
Have influence on the normal aquifer yield and water quality of film.
Chinese patent 201621068555.0 disclose it is a kind of rapidly and efficiently and environmental protection sewage filter device, including this
Body, the inside terminals of the body are provided with dividing plate, and the body is arranged with two processing storehouses by dividing plate, and is set inside processing storehouse
There are the first hydraulic stem and the second hydraulic stem, the top of the first hydraulic stem and the second hydraulic stem is connected with the lower surface of filter,
The both sides of filter are equipped with chute, and the top of dividing plate is provided with first through hole, and the left side of first through hole is provided with permeable membrane, infiltration
The right side of film is provided with magnetic valve, and the top of body is provided with the second through hole, and the other end of efferent duct is extended by interspersed second through hole
To the inside of body, processing is exported in the middle part of the lower end of storehouse provided with pollutant.
Chinese patent 201110316462.0 disclose it is a kind of can realize the cartridge filter of on-line automatic backwash, its wrap
