Description

Integrated sewage treating apparatus

The utility model relates to a kind of device of disposing of sewage, and especially relates to a kind of incorporate waste disposal plant.

At present, aggravation along with environmental pollution, water body in large eutrophication and red tide take place, cause the extreme of water resources in short supply, the strict legislation of control that pollute water countries in the world, to remove organism, nitrogen, the phosphorus of removing the arch-criminal who causes body eutrophication when removing organic pollutant change by original.Nitrogen, phosphorus are being removed, most bioremediations that adopt, in numerous denitrogenation dephosphorizing treatment process, its essence is anaerobism, anoxic, aerobic various combination.The subject matter that exists, on mechanism, denitrogenation requires the mud of biological treatment long age, and the mud that dephosphorization requires is short age; Nitrate is back to anaerobic zone has detrimentally affect to the anaerobic phosphorus release that gathers bacterium, anaerobic phosphorus release, and anoxic denitrification exerts an adverse impact; The problems such as sequencing of anaerobic phosphorus release and anti-digestion.From design or be to need the vast scale of the mixed solution (A that refluxes ₂O, UCT technology etc.), auxiliary facility is more, or is that structures are more, flow process is very long, take up an area of many, investment is big.Adopt more denitrification dephosphorization technique that oxidation ditch, SBR etc. are arranged at present on using, bigger but oxidation ditch takes up an area of, SBR requires self-con-tained unit preferably, and investment is big, and domestic electrical equipment self controlled element is prone to problem.

The purpose of this utility model provides that a kind of sludge yield is low, auxiliary facility is few, incorporate waste disposal plant.For achieving the above object, the utility model is made of preliminary sedimentation tank, adsorption tank, second pond, sterilization pool, biological contact oxidation pond, and link together by certain rule, become as a whole, in preliminary sedimentation tank, have by the bottom and lead to the mud return line that top communicates with equalizing tank outside this device, have in the second pond by the bottom and lead to the mud return line that top communicates with adsorption tank, mud return line is all set up the gas-adding pipe that air feed is carried spoil disposal usefulness gas.Owing to adopt above structure, this device reaches higher denitrogenation ability and certain phosphor-removing effect in efficient removal BOD, COD, SS.And the home and abroad like product has advantages such as investment is low, auxiliary facility is few, working cost is low, the operation operational management is simple at present.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is the section plan of the utility model integrated sewage treating apparatus.

Fig. 2 is the I-I face sectional view of integrated sewage treating apparatus shown in Figure 1.

Fig. 3 is the II-II face sectional view of integrated sewage treating apparatus shown in Figure 1.

Fig. 4 is the process flow sheet of the utility model integrated sewage treating apparatus.

From Fig. 1 to Fig. 3 as can be seen, the utility model integrated sewage treating apparatus is made up of preliminary sedimentation tank 1, adsorption tank 2, second pond 3, sterilization pool 4 and biological contact oxidation pond 5, and link together and be included in the casing according to certain rule, partition between each pond and shell are the steel plate manufacturing.From Fig. 4 process flow sheet as can be seen, also have equalizing tank beyond this device, be generally concrete basin, the capacity of equalizing tank must be determined according to factors such as drainage period, production technique.On the balanced water quality function of traditional regulating pondage basis, by technical measures, keep higher microorganism concn therein, its operation is operated than the higher SBR method with while denitrogenation dephosphorizing at present according to the home and abroad.Sewage is isolated in wherein sheet, block object beyond the equalizing tank earlier by grid, taking-up mummification outward transport, in order to avoid in equalizing tank, stop up water pump, pass through water pump, sewage is promoted in the adsorption tank 2 of this device, adsorption tank 2 is between preliminary sedimentation tank 1 and second pond 3, be provided with an aeration tube 11 from top to bottom in the adsorption tank 2, top communicates with other aeration tubes, the bottom communicates with the horizontal aeration tube that has some openings above, so that fully aeration carries out abundant oxidizing reaction, increase aerobic bacteria content in the water.The top of adsorption tank 2 communicates with the mud return line 7 of second pond 3, so that the sludge stream in the second pond 3 is returned in the adsorption tank 2, carries out recycling.Adsorption tank 2 tops one side, have serriform groove formula overflow port, communicate with the center water inlet pipe 9 of preliminary sedimentation tank 1 by pipe connecting 14, preliminary sedimentation tank 1 bottom becomes funnel structure, sewage in preliminary sedimentation tank 1 through the precipitation, mud by one arise from preliminary sedimentation tank 1 bottom, top is flowed back in the equalizing tank with the mud return line 6 that the outer equalizing tank of this device communicates, to carry out recycling, mud return line 6 one sides have been set up air-supply duct 18, and air feed is carried spoil disposal gas.Preliminary sedimentation tank 1 top sewage links to each other by the pipe connecting 13 that serriform groove formula overflow port and biological contact oxidation pond 5 communicate, and sewage flows into biological contact oxidation pond 5, and 5 fens A of biological contact oxidation pond, B two-stage adopt elastic solid filler, filler specific surface area 200M ²/ M ³, two-stage biological pond bottom communicates, and every grade of center is equipped with aeration tube from top to bottom, and top communicates with other aeration tubes, and bottom and two is arranged parallel aeration tube and is communicated, with abundant aeration, increase oxygen supply amount.Sewage is through behind the biological contact oxidation pond 5, communicate with second pond center water inlet pipe 10 by pipe connecting 15, be provided with in the second pond 3 two make progress the end of from, mud return line 7 that top communicates with adsorption tank 2, mud return line 7 one sides are set up the air-supply duct 18 that air feed is carried spoil disposal usefulness gas, flow back in the adsorption tank 2 by mud return line 7 through sedimentary mud, carry out recycling.Second pond 3 top sewage flow in the sterilization pool 4 by serriform groove formula overflow port.Be provided with aeration tube in the sterilization pool, and communicate, in the pond and be provided with automatic medicine adding apparatus with other aeration tubes, in disinfectant is housed, that disinfectant can adopt is solid-state, bleaching smart (sheet), Losantin, and after sterilization, the blow-off pipe 16 of sewage through being located at the sterilization pool middle and lower part discharges.Preliminary sedimentation tank 1, adsorption tank 2, second pond 3, sterilization pool 4, biological contact oxidation pond 5 tops all have manhole, so that observe and keep in repair.

How many big I of the present utility model is determined according to the amount of disposing of sewage.The capacity of preliminary sedimentation tank, adsorption tank, second pond, sterilization pool, biological contact oxidation pond also carries out the increase of corresponding proportion according to what of sewage quantity or reduces, and the thickness of each pipeline is also carried out the variation of corresponding proportion.
