Technical field
The utility model discloses a kind of new exclusive strainer head that is used for the aeration in sewage treatment biological filter.
Background technology
In the BAF of sewage disposal, carry out water distribution uniformity when guaranteeing the filter tank works better and when back flushing is carried out in the filter tank water distribution uniformity, gas distribution, generally all adopt strainer head to reach this purpose.But because the biological aerated filter process time of occurrence is not long, so also not at this kind filter tank characteristic and custom-designed special-purpose strainer head, at present generally all be select for use to use in the water treatment rapid filter to the water treatment strainer head, but owing to give the process object of water treatment and sewage disposal different with purpose, the water quality situation is also different, has many defectives so use to be in operation with strainer head to water treatment in BAF.
Because the object that water-feeding leaching pool is handled is clean earth surface water source, only contain tiny suspended substance in the water source, and the water that arrives the strainer head place is by the water purification behind the filtering layer, filtrate in the filter tank is the quartz sand about the about 1mm of diameter simultaneously, run off in order to stop sand grains to pass filter, so it is narrower to play the bar hole seam of water or mistake water, gas effect excessively on the filter of strainer head, is generally 0.2～0.5mm.
For BAF, the object of its processing is with different to water treatment, and main process object is for containing a large amount of suspension dirts and organic sewage.Because the suspension dirt is all with tiny bulk or cotton-shaped the existence in the sewage, its size is generally at 1～2mm, the overwhelming majority is all greater than the seam of the bar hole on the filter of feedwater strainer head width, so when adopting the feedwater strainer head to be used for BAF to carry out water distribution, suspension dirt in the sewage enters the filter inner chamber with sewage from the filter bar inner chamber of strainer head, being easy at the filter inner chamber water seam to be crossed in bar shaped stops up, can make on the cross section, filter tank water distribution inhomogeneous so on the one hand, simultaneously the head loss of filter is increased greatly, finally increase operation energy consumption; When the filter big area on the cross section, filter tank is stopped up, finally can cause the filter tank cisco unity malfunction because the cloth water electrode is inhomogeneous; In addition, owing to contain microorganism in the treatment sewage, microorganism exists in sewage under oxygen branch and the organic condition, be easy to be trapped at very narrow bar hole seam place, and utilize this place as the carrier of its growth and breed rapidly, thereby water bar hole seam is stopped up, and the viscosity of microorganism is very big, sticking power is stronger, in backwash process, also be difficult for microorganism is rinsed out, so prolific over time microorganism will be stopped up whole filter, influence the normal operation in filter tank; In addition, because the filter of feedwater strainer head partly is a dome-type, sphere upwards stretches in the filter material layer, vertically have narrower bar hole seam on the dome-type filter sphere, when BAF is stopped using, a large amount of suspended substances in the sewage and microorganism are deposited on owing to the natural subsidence effect on the sphere of dome-type filter, and the time has been grown the strip hole of more easily hardening and stopping up on the filter and stitched.In order to address the above problem, must adopt the special-purpose strainer head of BAF of novel texture.
Summary of the invention
The purpose of this utility model just provides and a kind ofly can play water distribution uniformity, gas distribution and be difficult for being stopped up by suspended substance in the sewage and being difficult for by the special-purpose strainer head of attached growth of microorganisms.
The special-purpose strainer head of the utility model BAF is that integral molded plastic forms, top is filter, the bottom is the filter bar, its principal feature is that filter is the hollow round table bodily form, form by filter top (1), bar hole seam (2), vertical flow deflector (3), horizontal flow deflector (4), filter base plate (9), vertical flow deflector (3) and horizontal flow deflector (4) are symmetricly set on the filter side, and form some bar holes seams in the filter side by them; Filter bar (6) is a tubulose, and filter bar inner chamber communicates with the filter inner chamber, and filter bar (6) middle and lower part has circular air inlet port (7) and bar shaped air inlet seam (8), and filter bar (6) bottom is not sealed; With filter base plate joint outside screw (5) is arranged on the filter bar, be convenient to use when strainer head is installed.
Since on the filter of the utility model strainer head bar hole seam width greater than the size of most suspension dirts in the water inlet less than the minimum grain size of ceramic grain filter, so suspension dirt in service can not stop up the bar hole seam on the filter during by filter with sewage, ceramic grain filter can not stop up the bar hole seam yet or pass the bar hole seam and fall in the distributing water room and run off simultaneously; Because the air water of the utility model strainer head outflow bar hole seam width is bigger, can not hold back the microorganism that contains in the raw waste water, does not breed in a large number at bar hole seam place so worry microorganism yet, thereby can not stop up the bar hole seam yet; Because the filter part profile of the utility model strainer head does not resemble the semisphere of feedwater strainer head, but cone cylinder body shape, the bar hole seam neither be opened on the ball surface of semisphere filter, but open on the sidewall of cone cylinder body shape filter, so when BAF is stopped using, a large amount of suspended substances in the sewage and microorganism be because natural subsidence effect and can directly not drop on bar hole and sew on, thereby do not have to stop up because of hardening the sorrow of the bar hole seam of filter.
