Description
Technical field
The present invention relates to waste disposal plant, especially a kind of pressure type integrated biological treatment apparatus for sewage.
Background technology
In existing life and industrial organic waste water, the biological sewage treatment device, as adopt the swash plate preliminary sedimentation tank, the press contacts oxidation pond arranged, many ponds being combined into one biological sewage treatment device such as spontaneous flotation settling tank, sludge digestion tank, sterilization pool, all be difficult to reach the zero release of organic sludge, particularly the cleaning of the mud in device difficulty is big, directly has influence on the continuous operation of device.
Summary of the invention
Purpose of the present invention just provides that a kind of volume is little, efficient is high, energy consumption is low, the amount of disposing of sewage is big, anti impulsion load capacity height, operation are reliable continuously, and can realize the pressure type integrated biological treatment apparatus for sewage of inorganic mud gravity flow discharging, organic sludge zero release.
Pressure type integrated biological treatment apparatus for sewage of the present invention comprises hydrolyzing regulation pond, sewage pump, Aeration fan, chlorine dioxide generator, electrical control cabinet and close-coupled processing jar, be divided into water distributing area successively in close-coupled processing jar, preliminary sedimentation tank, contact-oxidation pool, sludge digestion tank, spontaneous flotation settling tank and sterilization pool, be provided with dividing plate between each pond, hydrolyzing regulation pond passes through pipe connecting, sewage pump and water intaking valve link to each other with close-coupled processing jar of interior water distributing area, on the sterilization pool of close-coupled processing jar the other end end water outlet exhaust-control valve is housed, dividing plate bottom between water distributing area and preliminary sedimentation tank has cavity, dividing plate top between preliminary sedimentation tank and contact-oxidation pool is grille network, the chamber is opened in the bottom, dividing plate bottom between contact-oxidation pool and sludge digestion tank has cavity, dividing plate top and bottom between sludge digestion tank and spontaneous flotation settling tank all have cavity, and the dividing plate top between spontaneous flotation settling tank and sterilization pool has through hole; Contact-oxidation pool can adopt plural contact-oxidation pool serial connection, the chamber is opened in the employing bottom therebetween, the bottom is the dividing plate separation of grille network, place filling carrier in the contact-oxidation pool, the contact-oxidation pool bottom links to each other with Aeration fan by airduct, top and air water liaison tube join, and the other end of air water liaison tube links to each other with the water-gas distribution pipe of spontaneous flotation settling tank inner bottom part; The sludge digestion tank bottom is communicated with the hydrolyzing regulation pond bottom by the mud discharging pipe, and sludge digestion tank top joins with return line and mud discharging pipe, and the preliminary sedimentation tank bottom links to each other with the mud discharging pipe through pipeline; Sterilization pool top is provided with the sterilization supply device, and the sterilization supply device is connected with chlorine dioxide generator.
The principle of work of pressure type integrated biological treatment apparatus for sewage of the present invention is: the sewage gravity flow enters hydrolyzing regulation pond, be pressurized to 0.15～0.2Mpa through sewage pump, enter treatment unit by water intaking valve, inclined tube bottom in water distributing area is from the bottom to the preliminary sedimentation tank, motion from bottom to top then, most suspended matters (containing organic and inorganic impurity) are carried out mud, water sepn, and supernatant liquor enters contact-oxidation pool, and mud is the parallel contact-oxidation pool bottom that is pushed under the effect of pressure water.Contact-oxidation pool adopts the air oxygenation to promote the round-robin operation scheme, air is provided by aeration blower, the part microorganism is attached to the filling carrier surface with biomembranous form, another part then suspends in water with the form of active sludge, the body of calming the anger of aeration blower, provide oxygen for microorganism on the one hand, rise on the other hand and stir and mixing effect.Organism in the sewage with fully contact biochemical hydrolysis attached to the microorganism on the filler, simultaneously microbial film is produced certain souring, promote biomembranous renewal, make biochemical treatment remain at efficient state, constantly circulation is mobile in the pond for filling carrier, can prevent effectively that also filler from stopping up, and guarantees the continuous operation of device.For improving wastewater treatment efficiency, hour amount of disposing of sewage reaches the above device of 30T, and the above contact-oxidation pool of secondary should be set, when the supernatant liquor overflow of one-level contact-oxidation pool to the two-stage biological contact oxidation pond, carry out pressurized aeration once more, make the biochemical again hydrolysis of organic substance in the sewage.The bottom of MULTI CONTACT oxidation pond is provided with the mud passage, because of the mud (containing inorganic and organic composition) under reprecipitation, still be pushed into sludge digestion tank by the stress level of system, supernatant liquor and residual gas are then sent into spontaneous flotation settling tank by the air water liaison tube.Owing to enter the sewage of spontaneous flotation settling tank, carrying the residual gas behind the contact-oxidation pool aeration secretly, enter spontaneous flotation settling tank bottom by the water-gas distribution pipe, residual oxygen in the residual gas be utilized once more with sewage in organism catalytic oxidation once more, the final utilization ratio of airborne oxygen is reached capacity, the existence of residual gas, produce the air supporting effect, countless microbubbles is attached on the fine impurity particle, form scum silica frost with air bubble buoyancy to the water surface, overflow is to sludge digestion tank, and big material then is deposited in the bottom with the inclined tube effect, finally enter sludge digestion tank, the clear liquor of middle and upper part then enters sterilization pool by through hole.Sludge digestion tank has been admitted preliminary sedimentation tank, contact-oxidation pool, the active sludge of flotation settling tank and sewage, active sludge relies on deadweight to be deposited on the bottom, under the sealing anoxic condition, produce anerobe, continue the digestion excess sludge, top sewage and residual air then directly return by the sewage backflow pipe and enter to hydrolyzing regulation pond, quicken the hydrolysis reaction of hydrolyzing regulation pond, simultaneously because of sewage backflow, make that the sludge digestion tank of relative dead zone has obtained a relative negative pressure in the system, under the power of pressurization sewage cooperated, mud successfully was absorbed by the mud discharging pipe and is concentrated in the hydrolyzing regulation pond in the system, makes the discharge water turbidity obtain further assurance.Turbidity by automatic detection return line, also can help to realize the full-automation operation of complete assembly, that is: when turbidity is too high, can or reduces sump pump and look up and down by automatic regulating measure increasing quantity of reflux, increase the sewage disposal residence time, guarantee that the every index of sewage discharge is up to standard.
Pressure type integrated biological treatment apparatus for sewage volume of the present invention is little, compare the like product volume and can reduce 25%～50%, it also has the efficient height, cost is low, energy consumption is low, installation is convenient, the characteristics of inorganic mud gravity flow discharging, organic sludge zero release, the resistance to overload shock processing power can reach 100%, sewage and factory's organic waste water of be specially adapted to the to dispose of sewage following sub-district of discharge capacity 200T/h, market town, school, hospital, office, hotel, life.
