Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model domestic sewage in rural areas by using integrated equipment for wastewater treatment.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be emphasized that, following explanation is only exemplary, rather than in order to limit scope of the present utility model and application thereof.
Consult Fig. 1, according to embodiment of the present utility model, domestic sewage in rural areas by using integrated equipment for wastewater treatment comprises hydrolysis acidification pool, contact-oxidation pool, MBR membrane bioreactor and sterilization pool, the entrance of hydrolysis acidification pool is connected to septic tank, septic tank receives the sewage from sewage discharge point, the sewage of septic tank output is delivered to hydrolysis acidification pool through mechanical filter screen, the outlet of hydrolysis acidification pool connects the entrance of contact-oxidation pool, the outlet of contact-oxidation pool connects the entrance of MBR membrane bioreactor, the outlet of MBR membrane bioreactor connects the entrance of sterilization pool, the outlet of sterilization pool is as the water outlet of equipment.Wherein, from septic tank out sanitary sewage first after mechanical strainer filtering, with pump, pump into the hydrolysis acidification pool acidification that is hydrolyzed, then flow to contact-oxidation pool and carry out aerobic treatment, water after finishing dealing with flows to MBR membrane bioreactor again and processes, and finally enters sterilization pool disinfection.
Sanitary sewage is collected into after septic tank by each sewage point, can effectively destroy the larger molecular organics in waste water, obviously improves the biochemical property of water.Entering before hydrolysis acidification pool carries out biochemical treatment, mechanical filter screen can be tackled larger suspended substance and foreign material.
In hydrolysis acidification pool, by biological bacteria effect, the larger molecular organics in sewage obtains clearing up to a certain extent, becomes the micromolecular organism that acid, alcohol etc. are conducive to the aerobic treatment of back segment.It is a kind of technique between aerobic and anaerobic treatment that acidication is processed, and can reduce processing cost and improve processing efficiency.Hydrolysis acidification pool is different from the hydrolysis acid-producing bacteria speed of growth according to methanogen, anaerobic treatment is controlled to the first and second stages of shorter anaerobic treatment of reaction times, under a large amount of hydrolytic bacterias, the effect of acidifying bacterium, by insoluble hydrolysis of organic matter, be dissolved organic matter, the macromolecular substance of difficult for biological degradation is converted into the process of the small-molecule substance of readily biodegradable, thereby improve the biodegradability of waste water, for subsequent disposal is established good basis.
Preferably, adopt perforated pipe water distributor, water distributing pipe arm in hydrolysis acidification pool, water outlet is apart from 150mm-200mm at the bottom of pond.Controlling hydraulic detention time is 5 hours, controls current lift velocity 0.5-0.8m/h.
Hydrolysis acidification pool water outlet can be flow automatically and be entered contact-oxidation pool.Bio-contact oxidation is that waste water aerobic is processed, the further oxygenolysis of micromolecular organism that it produces acidication by being attached to filling surface microorganism, thereby removal organism, bio-contact oxidation is also fine on the tolerance of the impact of the impact load in system simultaneously, and the water quality of processing like this water outlet will keep stable.
In contact-oxidation pool, adopt fixed type biological filler as microorganism carrier, growth has microorganism carrier to be submerged in water, and aerating system is the microorganism oxygen supply in reactor.Because microorganism fixed growth in catalytic oxidation is on biologic packing material, overcome suspension active sludge and be easy to the shortcoming running off, in reactor, can keep very high biomass.It is high that catalytic oxidation has volumetric loading, and the residence time is short, and organic matter removal is effective, and operational management is simple, and the little grade of floor space a little.Preferably, in contact-oxidation pool, filler volumetric loading is pressed 1500gBOD
5/ m
3d, 1.5 meters of bed stuffing heights, 0.4 meter of filler headwater depth, the superelevation of pond body (pond body exceeds the height of the highest permission liquid level) is 0.3 meter, contact-oxidation pool total height is controlled at 2.5-3 rice.Above-mentioned design can obtain good catalytic oxidation effect when obtaining higher processing speed.In addition, be 3h preferred effectively duration of contact, and gas-water ratio is 16:1.
Preferably, contact-oxidation pool connects hydrolysis acidification pool by sludge reflux system, and contact-oxidation pool water outlet part sludge reflux, to hydrolysis acidification pool, to guarantee hydrolysis acidification pool activated sludge concentration, and improves processing efficiency.Preferred reflux ratio is 1-2:1.
The water outlet of biological contact oxidation pond enters MBR membrane bioreactor, in MBR membrane bioreactor, keep high reactivity sludge concentration, can improve biological treatment organic loading, thereby reduce sewage treatment facility floor space, and by keeping low sludge loading to reduce surplus sludge volume.MBR membrane bioreactor mainly utilizes active sludge and the larger molecular organics in the membrane separation plant entrapping tank of being immersed in aerobe pond.Active sludge in MBR membrane bioreactor system (MLSS) concentration can be promoted to 8000～10,000mg/L, even higher; Sludge age (SRT) can extend to more than 30 days.MBR membrane bioreactor, because of its effective crown_interception, can retain longer microorganism of generation cycle, can realize deep purification of waste water, and Simultaneous Nitrification bacterium can fully breed in system, and its nitrification effect is obvious, and to deep phosphorous removal, denitrogenation provides possibility.
Water outlet flows into sterilization pool, qualified discharge after sterilization, also can reuse as flushed the toilet, greening etc.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
