Below in conjunction with accompanying drawing and embodiment the utility model is further described.
As shown in Figure 1: a kind of integrated sewage treating apparatus, comprise the hydrolysis acidification pool 1 that is wholely set successively, biological contact oxidation pond 2, settling tank 3 and sludge digestion tank 4, adopt dividing plate 5 to separate between four, the downside of the packing layer 12 in hydrolysis acidification pool 1 and the biological contact oxidation pond 2 all is provided with the boring aeration pipe 13 that links to each other with extraneous source of the gas, wherein be provided with water-in 6 on the top of hydrolysis acidification pool 1, the bottom of hydrolysis acidification pool 1 links to each other with biological contact oxidation pond 2 by the through hole 7 that arranges on the dividing plate 5, boring aeration pipe 13 in the biological contact oxidation pond 2 is provided with equally distributed aeration head 14, the top of biological contact oxidation pond 2 is provided with sluice groove 8, sluice groove 8 is connected by the water inlet pipe in sluice pipe 9 and the settling tank 3, settling tank 3 adopts the bottom of vertical sedimentation basin and settling tank 3 to be connected by the through hole 7 on the dividing plate 5 and sludge digestion tank 4, sludge digestion tank 4 is provided with the mud return line that is connected with biological contact oxidation pond 2, is provided with the supernatant liquor refluxing opening 16 that links to each other with hydrolysis acidification pool 1 by pipeline on the top of sludge digestion tank 4; The top of settling tank 3 is provided with the overflow weir 11 that is connected with clear water sterilization pool 10 in addition, and clear water sterilization pool 10 is provided with water outlet 15.All be provided with in addition the manhole 17 for maintenance on hydrolysis acidification pool 1, biological contact oxidation pond 2, settling tank 3 and the sludge digestion tank 4.
The action principle of the utility model each several part is as follows.
Hydrolysis acidification pool 1 mainly carries out pre-treatment to sewage exactly, waste water in the water is carried out certain anaerobically fermenting, the biodegradability of sewage is improved, this is to step important before the sewage disposal, can directly affect efficient and the treatment time of the sewage disposal in later stage, can farthest improve the efficient of sewage disposal and reduce consumption.Sewage has reduced the concentration of suspended substance, organic pollutant and nitrogen after hydrolysis acidification pool 1 is processed, also reduced the load of follow-up contact-oxidation pool.Hydrolysis acidification pool has following several effects:
1), filteration: filler is held back large particulate matter and the suspended substance in the filtered water inlet;
2), hydrolytic action: the material that anaerobion can be micromolecular solubility with macromolecular insoluble material hydrolysis;
3), sorption: the organic pollutant in anaerobion absorption, the absorption water, a part are for the growth and breeding of self, and a part is discharged with the form of biogas;
4), denitrogenation: to hydrolysis acidification pool, the denitrifying bacteria in the anaerobion can utilize the nitric nitrogen in the recirculation water and be translated into nitrogen with the contact-oxidation pool effluent recycling, to remove the nitrogen material in the sewage.
Biological contact oxidation pond 2 is divided into several grades according to the pollution level difference of water treatment, and coventional type and reinforced is generally judged according to the time of processing.Treatment time is not more than four hours just uses medium-sized oxidation pond, the reinforced oxidation pond of the use for the treatment of time between 4-6 hour.Mainly be to use acidication 1 water outlet to carry out biochemical treatment from flowing to biological contact oxidation pond 2, most of organism obtains degraded and purification at this in the raw waste water, aerobic bacteria is take filler as carrier, utilize the organism in the sewage to be foodstuff, the organic substance decomposing in the sewage is become inorganic salts, thereby reach the purification purpose, the existence of aerobic bacteria, enough oxygen must be arranged, enough dissolved oxygens are namely arranged in the sewage, to reach the purpose of biochemical treatment.Biological contact oxidation pond 2 air are provided by blower fan, biological contact oxidation pond 2 interior employing novel elastic 3-D fillers, this filling surface is long-pending than large, long service life, easy to be filmed, corrosion-resistant, adopt aeration head 14 aerations at the bottom of the pond, make the rate of transform of dissolved oxygen high, the advantages such as lightweight, aging, difficult obstruction, long service life are arranged simultaneously.Biological contact oxidation pond 2 further reduces the organic contamination substrate concentration in the sewage, and water outlet CODcr, BOD5 clearance reach more than 80%, can reach state secondary effluent standard.Biological contact oxidation pond has following several effects:
1) adsorption: aerobic microbiological on filler in the growth and breeding process mutually section's knot form surface-area microbial film larger, that concentration is higher, most organic pollutant in the planar water makes the Pollutant levels reduction in a large number;
2) picked-up, Decomposition: in the situation of continuous blowing air in reactor, aerobic microbiological can be taken the photograph the organic pollutant of absorption in the human body as nutritive substance, carry out metabolism, a part is used for the growth and breeding of self, and a part is converted into carbonic acid gas and water.
At the bottom of settling tank 3 utilizes action of gravity to make proportion in biological contact oxidation pond 2 water outlets sink down into the pond greater than the suspended sludge of water, thereby make it from water, to remove, guarantee preferably effluent quality; A mud part that is settled down to the bottom is back to biological contact oxidation pond 2, and to keep the sludge concentration of catalytic oxidation bed, another part effluxes and carries out sludge treatment.
Clear water sterilization pool 10 is by adopting solid chlorine that water outlet is carried out disinfection, can effectively kill the pathogenic microorganisms such as bacterium in the water, intestinal bacteria, virus, so that the water after processing is limpid transparent, odorless, bacterial count and coliform count can meet state sewage emission standard.
The utility model has been given full play to hydrolysis acidification pool 1, the biological density that biological contact oxidation pond 2 biofilm reactors such as grade have is large, durability against pollution is strong, power consumption is low, operate stable, characteristics easy to maintenance, the ability of hydrolysis acidification pool 1 anti-shock loading is strong and have a denitrogenation dephosphorizing ability, filler in the biological contact oxidation pond 2 mostly is the combination wadding, light weight, high-strength, physicochemical property are stable, specific surface area is large, the microbial film adhesive ability is strong, sewage and biomembranous contact efficiency are high, biological contact oxidation pond 2 interior employing aeration heads carry out blast aeration simultaneously, fibrous bundle is constantly floated, aeration is even, microorganism growth is ripe, has the feature of activated sludge process.The stable effluent quality of this integrated sewage treating apparatus, sludge yield is few and be easy to process; Whole plant can be located on the ground, also can be embedded in underground, be easy to automatic control and management, simple to operate and less investment, the scope of application is in the situations such as the water yield is less, Pollutant levels are little, composition is uncomplicated, the place is limited, need consideration surrounding environment is beautified factor, is applicable to simultaneously hotel, restaurant, sanatorium, hospital, school, market.The sanitary sewage disposals such as residential quarter, villages and small towns, vessel harbour, station, airport, factory, mine, landscaped area or with the processing of the similar various industrial organic sewages of sanitary sewage.
Above embodiment only is explanation technological thought of the present utility model, can not limit protection domain of the present utility model with this, every technological thought according to the utility model proposes, any change of doing on the technical scheme basis all falls within the utility model protection domain; The technology that the utility model does not relate to all can be realized by prior art.
