Sewage water treatment method commonly used now comprises physical method, chemical process, biological method etc., and wherein bioremediation generally comprises aerobic method and anaerobic process, and it is by active sludge the organism in the sewage to be carried out digestion process.Utilizing in the device that activated sludge process handles sewage of adopting at present, generally the mud refluxing unit need be set separately, so that will be by the activity sludge reflux of settlement of sewage to the biological sewage treatment pond, thereby facility investment be big, running cost is high, maintenance rate is high; Though the intermittent activated sludge treatment unit does not need to be provided with the mud refluxing unit, owing to its automatic control degree is had relatively high expectations, and water outlet can not be continuous, thereby cause the processing of investing greatly and being not suitable for big yield.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of facility investment little, the integrated self-refluxing multi-stage biochemical sewage treatment device that processing cost is low.
The technical scheme that its technical problem that solves the utility model adopts is:
Integrated self-refluxing multi-stage biochemical sewage treatment device is characterized in that this waste disposal plant comprises anaerobic zone, is provided with the sewage import in the bottom of anaerobic zone; The oxygen-starved area, itself and anaerobic zone are provided with partition wall; Aerobic zone, the bottom of aerobic zone is connected with the oxygen-starved area, in the bottom of aerobic zone aerating apparatus is installed; The settling region, the bottom of settling region is provided with oblique bucket, and tiltedly bucket communicates with aerobic zone, and tiltedly bucket is arranged to rely on the mud self gravitation that mud is glided to the aerobic zone bottom, and the top of settling region is provided with and overflows tank.
As the utility model improvement of the technical scheme, the bottom of anaerobic zone is provided with the sewage water inlet water distributor that connects with the sewage import.
As the utility model further improvement in the technical proposal, aerobic zone top is provided with the overflow weir that is connected with the oxygen-starved area.
Separating effect for the sewage after guaranteeing active sludge and handling is provided with the tube settling district in the above-mentioned settling region.
Above-mentioned aerating apparatus can adopt the aeration head that communicates with extraneous source of the gas.
As the further improvement of the utility model technique scheme, anaerobic zone, oxygen-starved area, aerobic zone and settling region circularize setting.
The beneficial effects of the utility model are: waste disposal plant of the present utility model is provided with anaerobic zone, oxygen-starved area, aerobic zone and settling region, also can cancel anaerobism, anaerobic treatment operation simultaneously according to the needs of actual treatment, mutability is strong, thereby can adapt to various sewage quality; The utility model need not the mud refluxing unit, also need not to be provided with automation control appliance, thereby can reduce facility investment, reduces processing cost; Aerobic zone top is provided with the overflow port that is connected with the oxygen-starved area, can realize that aerobic biochemical is handled and the alternately conversion of anoxic biochemical treatment; Sewage import of the present utility model is connected with sewage water inlet water distributor, thereby the sewage that enters waste disposal plant is evenly distributed, and helps stablizing sewage treatment effect; Partition wall bottom UNICOM between oxygen-starved area, aerobic zone and the settling region makes body of wall need not to bear too big pressure, thereby makes construction costs low; Anaerobic zone, oxygen-starved area, aerobic zone and settling region circularize setting, so its compact construction, and floor space is little.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the plot plan of Fig. 1;
Fig. 3 is the plot plan of the another kind of embodiment of the utility model;
Fig. 4 is the plot plan of the third embodiment of the utility model.
Embodiment
With reference to Fig. 1, Fig. 2, integrated self-refluxing multi-stage biochemical sewage treatment device disclosed in the utility model, comprise anaerobic zone 1, oxygen-starved area 2, aerobic zone 3 and settling region 4, be provided with sewage import 5 in the bottom of anaerobic zone, be provided with partition wall between anaerobic zone 1 and the oxygen-starved area 2, the sewage of anaerobic zone can be by the partition wall overflow to the oxygen-starved area.The bottom of aerobic zone 3 is connected with oxygen-starved area 2, in the bottom of aerobic zone 3 aerating apparatus is installed, the aeration head 6 of aerating apparatus for communicating with extraneous source of the gas; 4 bottom is provided with oblique bucket 7 in the settling region, tiltedly bucket 7 communicates with aerobic zone 3, tiltedly bucket 7 is arranged to make mud to rely on self gravitation can glide to the shape of aerobic zone 3 bottoms, and the top of settling region 4 is provided with and overflows tank 8 simultaneously, and it roughly is provided with tube settling district 11 in the mid-way.
Principle of work of the present utility model is such: sewage enters anaerobic zone from the bottom of anaerobic zone, and from it portion's overflow to the oxygen-starved area, handle by anaerobic biological at anaerobic zone and oxygen-starved area, sewage after the processing enters aerobic zone by the bottom of oxygen-starved area again, carries out aerobic biochemical and handle under the effect of active sludge.When the aeration head aeration, gas rises, drive on the current direction and flow, and enter the oxygen-starved area by aerobic top overflow weir, the water of bottom, oxygen-starved area replenishes to aerobic zone simultaneously, formation circulates, sewage and the active sludge intermixture handled through aerobic biochemical flow into the settling region with extremely slow speed from the break joint between aerobic zone and the settling region, inclined tube through the settling region separates, clear water flows out through overflowing tank, mud sinks down into sludge bucket, and tiltedly the mud in the bucket relies on the mud self gravitation to glide to the aerobic zone bottom, stirs at quilt under the effect of aerating apparatus and is with the aerobic zone top to enter the waterpower circulation.
Waste disposal plant of the present utility model is provided with anaerobic zone, oxygen-starved area, aerobic zone and settling region, can handle industrial sewage and sanitary sewage, particularly industrial ammonia-containing water.Wherein anaerobic zone can carry out degradation treatment to macromolecular organic pollutant, also organic acid can be resolved into methane by methanobacteria; And the oxygen-starved area both can be used as denitrification zone, also can be used as general aerobic area, when its during as denitrification zone, itself and aerobic zone have formed denitrification-nitrated recycle system, eliminate ammonia nitrogen and nitrate in the water effectively; And, can interrupt the long chain molecule that aerobic zone can't decompose as general aerobic area, its final aerobic sigestion is fallen.
The utility model also can be cancelled anaerobism, anaerobic treatment operation according to the needs of actual treatment, thereby mutability is strong, can adapt to various sewage quality.
As shown in the figure, also be provided with the sewage water inlet water distributor 9 that connects with the sewage import in the bottom of anaerobic zone, thereby the sewage that enters waste disposal plant is evenly distributed, help stablizing sewage treatment effect.
Be provided with the overflow weir 10 that is connected with the oxygen-starved area on aerobic zone top, can form like this from aerobic biochemical treatment and handle, handle the water treatment circulation that aerobic biochemical is handled from anaerobic biological again to anaerobic biological.
