Description
Technical field
The utility model relates to a kind of waste disposal plant, belongs to sewage treatment area, is applicable to the processing of life kind sewage and industrial organic waste water etc.
Background technology
Chinese patent 98227172 discloses a kind of " air-dissolved biological fluidized bed ", fluidized-bed cylindrical shell top is provided with slag scraping mechanism and water outlet, packing layer is housed in the cylindrical shell, and a dissolved air water rising pipe that has the sewage admission port and the dissolving of gas admission port links to each other with the water-in of cylindrical shell bottom.For reaching emission standard, the sewage behind the biochemical reaction enters the filter of postorder again after air supporting is handled, need the pump equal power device, and floor space is bigger on the one hand, and power consumption is also many on the other hand; The disrupter of any clear water and suspended substance is not set in the air flotation zone in addition, and separation efficiency is still waiting to improve.
Summary of the invention
The utility model is just in order to overcome above-mentioned deficiency, a kind of integrated sewage disposal device is provided, its with air-dissolving air-float, biological floating bed, synchronous nitration and denitrification process, automatic filtration in one, can in same equipment, same process, carry out comprehensive treating process according to the pollutent of different properties, different components, different states in the sewage.Specifically be achieved like this: integrated sewage disposal device, comprise biochemical zone, air flotation zone and filtrating area, it is characterized in that air flotation zone is built-in with some inner cores, described inner core is built-in with the dissolved air water reliever, the inner core end opening is communicated with biochemical zone water, the air flotation zone top is equipped with slag scraper, the bottom is equipped with header, the biochemical zone bottom is equipped with water inlet pipe and dissolved air water water distributor, the centre is a floating stuffing, one side of air flotation zone and biochemical zone is equipped with filtrating area, and the water inlet pipe pipe of filtrating area connects the air flotation zone header.
Under the prerequisite that does not increase equipment volume, in order to have prolonged the mixing time of dissolved air water, the inner core of the utility model air flotation zone is designed to reverse taper, has improved the removal efficient of suspended substance.Inner core can be set to one to four, the best is two, be parallel double pond air-dissolving air-float, dissolved air water adopts the atomizing inflation process, the clear water after the biochemical treatment is taken from water inlet, be that the biochemical zone top is equipped with the outer dissolving of a rising pipe linking device, the dissolving bottom is communicated with the dissolved air water water distributor in the biochemical zone, dissolving is built-in with spraying gun, biochemical water forms atomizing state by the spraying gun in the dissolving, air is instantaneous fusing in droplet under pressure, and the air pressure entry replaces air water mixed, and air water solubleness can reach 100%.Dissolved air water is after centrifugal reliever discharges, and the microbubble particle diameter of generation reaches 10 μ m, can float the above suspended substance of 10-2010 μ m rapidly.
The biochemical oxygen demand (BOD) of the utility model microorganism is provided by dissolved air water, dissolved oxygen concentration is greater than 12mg/l, and the mass transfer rate of transform 35-50% of oxygen is near the efficient of pure oxygen, than traditional micro-pore aeration, plate-spinning aeration and the 25-30 of aeration efficient raising under water doubly, biochemical speed improves 8 times.The floating stuffing that biochemical zone is filled is made up of the corpus fibrosum of hollow multiaspect body skin and Qi Nei, has aerobic and anaerobism function concurrently, loading level be the biochemical zone volume 40-70%, filler can be done 360 ° and freely rotate under the fluidic drive.Because filler is fit to multiple microbial growth environment respectively, is equivalent to exist numerous miniature heterogeneous bio-reactor at biochemical reaction zone, nitrification and denitrification carries out synchronously.The suspension degree of filler can change along with the change of concentration of wastewater in the treating processes, and the upflow velocity by adjusting dissolved air water and utilize the adsorptive power of air filled cavity on filler can be adjusted the suspended state of filler arbitrarily.
Filtrating area of the present utility model is made up of several filter tanks, adopt gravity type boat davit valveless siphon principle to filter and back flushing, unpowered outfit, can be according to influent quality alternately back flushing automatically in good time, need not complicated time-program(me) Controlling System and back-purge system, can select for use fibrous nodules, quartz sand, gac etc. to make filtrate in the filtrating area, the voidage height, the mud supporting capacity is strong, filtrate can be with the reduction gradually of backwash rate, uniform distribution, the excessive and filtrate of coefficient of expansion filtering layer short circuit when disorderly layer causes filtering when need not to worry flushing has guaranteed the stability of filtering water.
The utility model integrates air-dissolving air-float, biological floating bed, synchronous nitration and denitrification process, automatic filtration, can be according to the pollutent of different properties, different components, different states in the sewage, in same equipment, same process, carry out comprehensive treating process, CODcr, BOD in the disposable synchronous removal sewage of energy
5SS, ammonia nitrogen, phosphorus, LAS, lipid, turbidity, colourity, volatile phenol, sulfide etc., need not proceed step by step, this compact equipment, it is biochemical only to need a lift pump just can satisfy, air supporting, the Inlet and outlet water power demand of filtering system, less energy consumption, set a recycle pump and a typhoon machine and just can satisfy air supporting generation superfine air bubble, the needs of biochemical high density dissolved oxygen and denitrification lower concentration dissolved oxygen, the unit equipment processing power is not limited by the water yield, energy-saving effect is obvious and stable equipment operation is reliable, is applicable to the processing of life kind sewage and industrial organic waste water etc.
