Description

The anaerobic fluidized bed waste disposal plant of high-effect internal recycle active sludge
The utility model relates to waste disposal plant, the anaerobic fluidized bed waste disposal plant of especially a kind of high-effect internal recycle active sludge.
Sewage disposal is the problem that current social people are concerned about; the industrial sewage and the sanitary sewage that are not discharged for the physical environment of protecting the mankind to depend on for existence pollute; the treatment process of sewage is all studied by environmental protection academia in depth both at home and abroad, and constantly develops different waste disposal plants or equipment.Upflowing active sludge bed UASB and internal recycle IC sewage disposal technology etc. all belong to comparatively advanced sewage disposal technology.Especially upflowing active sludge bed UASB technology has been studied more deeply in theory, is winning a series of victories aspect high-concentration industrial organic waste water is handled.In states such as Italy, Portugal, Colombia, India, Brazil, Egypt sanitary sewage disposal factory that all to have above flow type active sludge bed UASB be main body, the effect of its processing, the advanced person of technology, level of automation is high and take up an area of few, reduced investment, working cost are low etc., and comparing with existing sewage treatment process all has its unique distinction.Internal recycle IC belongs to contemporary state-of-the-art sewage disposal technology theoretically, still is not reported but adopt internal recycle IC technology to carry out sanitary sewage disposal.
The anaerobic fluidized bed waste disposal plant of high-effect internal recycle active sludge that it is one that the purpose of this utility model provides a kind of excellent characteristics that collect upflowing active sludge bed UASB and internal recycle IC technology.
The anaerobic fluidized bed waste disposal plant of high-effect internal recycle active sludge of the present utility model, comprise: by tower body, water distributor and can be with solid phase particles or floc sludge interception, the methane gas of gas phase is introduced the upflowing active sludge bed that the three-phase of high altitude discharge pipe divides device to constitute, it is characterized in that: be provided with one in the tower body of upflowing active sludge bed and fall funneling internal recycle device, the bottom periphery of this internal recycle device is connected with the tower body inwall, and set internal recycle device is separated into the tower body inner chamber from bottom to top: hydrolysis area, first reaction zone, second reaction zone; The tower body top is provided with one can exhaust formula water inlet device with processed water between in the lasting interval mode input tower.
The anaerobic fluidized bed waste disposal plant principle of design of high-effect internal recycle active sludge of the present utility model is: internal recycle device and upflowing active sludge bed are combined dexterously, utilize the internal recycle device, upflowing active sludge bed tower body inner chamber rationally, is clearly demarcated into hydrolysis area, first reaction zone, second reaction zone and three-phase separation area, thereby the mixed solution of realizing sewage and mud carries out with inner loop mode in the process of the promotion mud come-up of pump pressure and methane gas; Exhaust the water inlet input of formula water inlet device as this device between employing, exhaust the mode of formula water inlet device periodic burst draining, flow is big when exhausting, can replenish the internal recycle energy, strengthen, accelerate mud and mixing of sewage biphase and mass transfer, improve treatment effect, energy efficient prevents line clogging.
The anaerobic fluidized bed waste disposal plant design science of high-effect internal recycle active sludge of the present utility model, rational in infrastructure, be characterized in: anti impulsion load is strong especially, for the big sanitary sewage of water quality, water yield fluctuation, during the low wash water high density, the corresponding raising of clearance; Otherwise clearance reduces.The unartificial automatic routine control of this automatic regulatory function can reach, and therefore, this device can keep the treatment effect of terminal more stablely.This device and traditional life sewage A/O, SBR compares with the oxidation ditch treatment process, have floor space little, shorten hydraulic detention time, reduce the useful volume of structures, reduce advantages such as investment.When this device is used for the community life sewage processing, do not need to be equipped with equalizing tank, the high and low loading zone of tower itself can be accepted very big change of water quality and impact, and finishes hydrolysis, acidization hereinto.
Concrete structure of the present utility model is provided in detail by the following drawings and embodiment.
Fig. 1 is the structural representation of the anaerobic fluidized bed waste disposal plant of this high-effect internal recycle active sludge.
Embodiment: from Fig. 1 can be clear that the main body of the anaerobic fluidized bed waste disposal plant of high-effect internal recycle active sludge be one by tower body 2, water distributor 3 and can be with solid phase particles or floc sludge interception, the methane gas of gas phase is introduced the upflowing active sludge bed 1 that the three-phase of high altitude discharge pipe divides device 4 to constitute, be provided with one in the tower body 2 and fall funneling internal recycle device 5; Internal recycle device 5 constitutes down funnel 8 by tapered tube 6 and interior pipe 7 and outer tube 9 is formed, funnel 8 bottom periphery of falling of internal recycle device 5 are connected with tower body 2 inwalls, set internal recycle device 5 is separated into tower body 2 inner chambers from bottom to top: hydrolysis area 10, first reaction zone 11, second reaction zone 12, fall to offer on funnel 8 tapered tubes 6 for what mud refluxed and loop back discharge orifice 13; Tower body 2 tops are provided with one can be with processed water to continue the box pulse water-feeding device 14 in the interval mode input tower, and box pulse water-feeding device 14 is connected with the water distributor 3 of upflowing active sludge bed 1 by pipeline 15.
This device operational process is: sewage is periodically from top to bottom entered to impact type the water distributor 3 of tower body 2 intracavity bottoms by pipeline 15 by box pulse water-feeding device 14, by water distributor 3 sewage is infused in tower body 2 inner chambers equably, and at the bottom of tower, 2 produce strong disturbances, make mud and sewage two-phase mass transfer thorough mixing in the tower body 2.Current rise after first reaction zone 11 enter internal recycle device 5 finishes anaerobic process, inner core 7 along internal recycle device 5 rises to spillway 16, by internal recycle device 5 inner core spillways 16 current are leaked into internal recycle device 5 outer tube pipes 9 from top to bottom, because internal recycle device 5 outer tube pipes 9 nozzles are shape, therefore be somebody's turn to do the passage of back taper funnel 6 formation of shape nozzle and internal recycle device 5, make sewage enter second reaction zone 12 and finish the anoxic process in the mode that spreads discharging.Current are 2 tortuous circuitous rings in tower, the abundant mass transfer of mud and sewage two-phase, in this process, input activity charcoal powder is carrier, the core that inoculation cultivation, domestication particle or floc sludge form, quickened the process of this inoculation and startup, improve steady running aftertreatment effect, shorten hydraulic detention time; Hypogene water behind second reaction zone 12 fails to be convened for lack of a quorum and takes away particle or cotton-shaped active sludge, under the mechanical retention effect of triphase separator 4, mud is stopped, mud is because of than great internal recycle device 5 bottoms that sink to, from falling the bottom of the inflow tower body 2 that loops back discharge orifice 13 on funnel 8 tapered tubes 6, discharge then by shore pipe 17; Water after the processing enters the overflow groove 18 of triphase separator 4 and discharges; The methane gas that produces in the treating processes will accumulate in tower body 2 inner chamber tops, introduce the eminence discharging by the delivery pipe 19 that is provided with.
