Description
Technical field
The utility model relates to a kind of waste disposal plant, particularly a kind of integrated A/O/MBBR reactor.
Background technology
In recent years, along with China's rapid development of economy, water environment pollution is day by day serious, country drops into substantial contribution and builds centralized sewage work and supporting sewage collecting pipe network for this reason, maintenance to water surrounding and improvement have obtained certain effect, but, building centralized sewage work exists scale of investment large, construction period is long, need the problem such as auxiliary construction sewage collecting pipe network and addressing and expropriation of land difficulty, for a large amount of country sewages and from urban district the trade effluent in area far away and sanitary sewage near build centralized sewage work often far water be difficult to resolve closely yearningly, and adopt middle-size and small-size decentralized type sewage treatment facility to process on the spot qualified discharge to the sewage producing, carry out pipeline network construction without dropping into substantial contribution, construction fund is few, construction period is short, addressing is flexible, for solving, China's water environment pollution problem is of great advantage.In addition; according to China environmental protection 12 planning; also strictly control as the binding indicator for the ammonia nitrogen concentration in sewage disposal discharge water, therefore, the middle-size and small-size sewage disposal device with denitrification functions has the huge market requirement and wide development space.
The existing middle-size and small-size sewage disposal device with denitrification functions, conventionally adopt A/O(anoxic/aerobic) technique or its mutation technique such as activated sludge process, biological contact oxidation process, SBR method, these techniques all can reach sewage drainage standard, but ubiquity flow process complexity, arrange and disperse, the problems such as floor space is large, and energy consumption is higher, and noise is large.
Summary of the invention
This practical new object is to provide a kind of integrated A/O/MBBR reactor with denitrification functions, this reactor is by A/O(anoxic/aerobic) Activated Sludge Process and MBBR(fluidized bed bio membrane reactor) technique organically combines, improve the removal effect to COD and ammonia nitrogen, adopted the centrifugal aerator of diving as biochemical oxygen replenishing equipment simultaneously, not only save air blast machine room but also effectively reduced the noise of sewage treatment facility, pass through Integrated optimization design, save sludge reflux pump, save floor space, reduce operation energy consumption, make up the deficiency of existing middle-size and small-size decentralized type sewage treatment facility.Compare prior art and equipment, there is effluent quality high-quality stable, denitrification effect is good, sludge yield is few, floor space is little, the advantages such as noise is low, energy-saving and cost-reducing, construction install convenience, can be widely used in various industrial and mining enterprises, residential quarters, villages and small towns sewage disposal, have certain novelty and stronger practicality.
Integrated A/O/MBBR reactor of the present utility model, comprise the circular cylinder body that is become oxygen-starved area, aerobic zone, guiding region, mud-water separation district and catchment area by several concentric(al) circles tubular baffle for separatings, be arranged on the water inlet water-distributing device on top, oxygen-starved area, be arranged on the floating stuffing at middle part, oxygen-starved area, be arranged on the centrifugal aerator of diving of bottom, oxygen-starved area, be arranged on the floating stuffing at middle part, aerobic zone, and the intake ducting being connected with the centrifugal aerator inlet mouth of diving.It is characterized in that described oxygen-starved area communicates with described bottom, aerobic zone, described aerobic zone communicates with described top, guiding region, described guiding region communicates with described bottom, mud-water separation district, described mud-water separation district communicates with described top, catchment area, described mud-water separation district communicates with bottom, described aerobic zone, and described intake ducting top communicates with atmosphere.
The utility model is to have organically combined A/O(anoxic/aerobic) Activated Sludge Process and MBBR(fluidized bed bio membrane reactor) technique, and a kind of integrated A/O/MBBR reactor of improveing and optimizing, compare with equipment with prior art, it has following beneficial effect: 1, more high-quality stable of effluent quality, denitrification effect is better, and sludge yield is few.This be based on: the one, increased anoxic MBBR section at the front end of aerobic MBBR section, formed two kinds of A/O techniques of both macro and micro, better for the removal effect of COD and ammonia nitrogen; The 2nd, catchment area is positioned at the outer shroud of equipment, and effluent weir hydraulic load is low, can effectively reduce the disturbance of water outlet to muddy water mixed solution, reduces water suspension content; The 3rd, mud all refluxes, and sludge loading is low, is conducive to active sludge and enters the endogenous respiration stage, thereby consume organic sludge.2, floor space is little.This structure of reactor compactness, above and below ground is arranged and all can.3, noise is low.This is that aerator is positioned at inside reactor based on having adopted the centrifugal aerator of diving, and noise is absorbed by water substantially.4, energy-saving and cost-reducing.This is the structure design based on special optimization, adopts gravity reflux mud, has saved sludge reflux pump.5, construction install convenience.This is to be highly integrated integration apparatus based on this reactor, without drum Ventilator Room and miscellaneous equipment, piping installation again, after equipment hoisting is in place, only needs to connect water inlet pipe and water outlet pipe.
brief description of the drawings: Fig. 1 is structural representation of the present utility model.
Embodiment: the utility model is described in further detail below in conjunction with the specific embodiment of accompanying drawing, structure shown in Fig. 1 is one of them preferred structure of the utility model, it is a kind of integrated A/O/MBBR reactor, mainly comprise by several concentric(al) circles tubular baffle for separatings and become oxygen-starved area 1, aerobic zone 2, guiding region 3, the circular cylinder body of mud-water separation district 4 and catchment area 5, be arranged on the water inlet water-distributing device 6 on 1 top, oxygen-starved area, be arranged on the floating stuffing 7 at 1 middle part, oxygen-starved area, be arranged on the centrifugal aerator 8 of diving of 1 bottom, oxygen-starved area, be arranged on the floating stuffing 9 at 2 middle parts, aerobic zone, and the intake ducting 10 being connected with centrifugal aerator 8 inlet mouths of diving.Oxygen-starved area 1 communicates with 2 bottoms, aerobic zone, aerobic zone 2 communicates with 3 tops, guiding region, and guiding region 3 communicates with 4 bottoms, mud-water separation district, and mud-water separation district 4 communicates with 5 tops, catchment area, mud-water separation district 4 communicates with 2 bottoms, aerobic zone, and intake ducting 10 tops communicate with atmosphere.
