Abstract
The utility model relates to a membrane filtering drainer, which comprises a water filtering and collecting system, a water draining system, a filter membrane automatic back flushing system, wherein, the water filtering and collecting system can be directly arranged in a biochemistry pool for directly filtering and draining physiochemical sewerage. The utility model has a double function for replacing a sedimentation tank and a filtering tank of the traditional technology, and the utility model can make physiochemical and industrial equipment very simple. The utility model not only can greatly raise physiochemical biochemistry efficiency but also can efficiently reduce the construction cost of sewage treatment works.
Description
The present invention is a sewage disposal device.
In the sewage biochemical processing process, no matter be aerobic process or anaerobic technique, the sewage behind the biochemistry all will enter settling tank post precipitation supernatant liquor and could discharge, even also needs to increase filter plant and dosing flocculation apparatus, and construction costs is improved.
In view of the existing deficiency of above-mentioned existing sewage biochemical process, the objective of the invention is to design a kind of membrane filtering drainage device, replacing settling tank and the filter plant in the existing biochemical process, with reach the water that improves the sewage biochemical efficiency and reduce construction costs and discharge can be directly as the purpose of industrial reuse water use.
According to design concept, membrane filtering drainage device of the present invention mainly comprises membrane filtration water gathering system, water exhaust system and filtering membrane automatic backwash system.
In order to be described in detail implementation detail of the present invention, provide most preferred embodiment of the present invention below in conjunction with accompanying drawing.
Accompanying drawing 1 is the membrane filtering drainage device.
Shown in accompanying drawing 1, accompanying drawing 2, membrane filtering drainage device of the present invention by many groups membrane filtration module 1 be fixed in the membrane filtration water gathering system formed on the ring-type header 2 equably, the water exhaust system be made up of discharge pipe line 5 and wet-pit 6 and the filtering membrane automatic backwash system that is made up of water level sensor 11, electrically operated valve 7, electrically operated valve 8, electrically operated valve 9, electrically operated valve 10 and controlling board 12 constitute.Wherein membrane filtration module 1 is to be placed on the support 4 that voidage makes greater than 50% tubing and with lock ring 13 filter bag 3 to be fixed on it with the filter bag 3 that the filtration membrane material is made.Support 4 tops are union 14, utilize the flare connection mode to be fixed on the header 2.
Implement the present invention, can directly the filtration water gathering system of described membrane filtering drainage device be put into biochemistry pool, under the draft effect of wet-pit 6, biochemical good sewage sees through filter bag 3 and enters in the header 2, send into clean water basin by discharge pipe line 5 again, because the pore size filter of filtering membrane all below 2 μ m, so can make the water turbidity of being discharged be no more than 5mg/l, directly can be used as industrial reuse water and uses.Filtering membrane can very all be retained in active sludge in the biochemistry pool on this on the other hand, makes the biomass in the pond keep higher rate, and biochemical efficiency is improved significantly.In a single day the flco amount that is adsorbed on the filter bag 3 in drainage procedure is bigger, the filtered water flux reduces, being directed at drainage efficiency reduces, must cause that then the water level in the biochemistry pool rises, reach behind the limit value water level sensor 11 at once instruction control dish 12 close electrically operated valve 7, electrically operated valve 8, open electrically operated valve 9, electrically operated valve 10, then make water in the clean water basin by wet-pit 6 by discharge pipe line 5 reverse sending in header 2 and the filtering film component 1, filter bag 3 is carried out back flushing, make the mud flco that is attached on the filter bag 3 break away from membranous wall, the filtered water flux is recovered, this moment, controlling board 12 was closed electrically operated valve 9 at once, electrically operated valve 10, open electrically operated valve 7, electrically operated valve 8 recovers normal draining.
Implement the present invention, can cancel the settling tank of biochemical process, filtering basin etc.Construction costs is reduced, and the processing efficiency of processing unit increase substantially, draining water quality is good.
