Wherein the implication of each Reference numeral is as follows:
1 settling region; 2 air chambers; 3 reflectors; 4 anaerobism grooves; 5 reaction zones; 6 sludge blankets; 7 gas-liquid-solid three-phase separators; 8 settling tanks; 9 aerobic slots; 10 two-phase shower nozzles; 11 settling tanks.
Embodiment
The utility model is made detailed description by the invention of following embodiment.But the utility model is not limited to described embodiment, and many distortion can also be arranged.Those skilled in the art change or change from the institute that content disclosed by the invention directly derives or associates, and all fall into protection scope of the present invention.
According to the utility model, as shown in Figure 4, described waste disposal plant comprises an anaerobism groove 4 and an aerobic slot 9, and preferably, described anaerobism groove 4 connects a settling tank 8, and more preferably, described aerobic slot 9 connects a settling tank 11.
According to the utility model, as shown in Figure 4, described anaerobism groove 4 comprises reaction zone 5 and gas-liquid-solid three-phase separator 7 from bottom to top.Retain a large amount of anaerobic sludges in the reaction zone of bottom, the mud with good sedimentation function and cohesion performance forms sludge blanket 6 in the reaction zone bottom.Sewage to be processed flows into from anaerobism groove 4 bottoms, mixes contacting with mud in the sludge blanket 6, and the organism in the microbiological degradation sewage in the mud is converted into biogas to it.Biogas is constantly emitted with the micro-bubble form, micro-bubble is in uphill process, constantly merge, form bigger bubble gradually, stirring on reaction zone 5 tops owing to biogas forms the mixed solution (mud and water) that sludge concentration is thinner, simultaneously because the result of aerogenesis, the tolerance that the part section passes through is more, form the air-flow of one rising, drive partially mixed liquid and rise together and enter triphase separator 7, when biogas is run into the reflector 3 of separator 7 bottoms, be folded to reflector 3 around, pass water layer then and enter air chamber 2, concentrate on the biogas of air chamber 2, derive with conduit, the solid-liquid mixed solution enters the settling region 1 of triphase separator through reflection, mud in the sewage flocculates, and particle increases gradually, and sedimentation under action of gravity.The mud that is precipitated on the reflector skew wall slides back in the anaerobic reaction district 5 along skew wall, makes a large amount of mud of accumulation in the reaction zone 5, overflows on 1 overflow weir top from the settling region with the processing water outlet after mud separates, and discharges the anaerobism groove then.
Gas-liquid-solid three-phase separator is the important component part of described anaerobism groove, and it comprises deflecting plate 3, settling region 1 and air chamber 2, and concrete structure can adopt arbitrary structure of Fig. 1, Fig. 2 or Fig. 3.
The shape of anaerobism groove 4 can be circular, square or rectangle.Highly be generally 3-8m, how build with Steel Concrete.According to organic matter of sewage concentration difference, the area of the area of lower reaction zone and settling region, top can be set to identical or different, for example, when the organic matter of sewage concentration ratio is higher, the settling region area that needs is little, the area of reaction zone can adopt and settling region area identical and shape, when organic matter of sewage concentration is low, the desilting area that needs is big, in order to guarantee the certain altitude of reaction zone, when the area of reaction zone can not be too big, then the area that can adopt reaction zone was less than the settling region, and namely the top area of anaerobism groove is greater than the area of bottom.
The advantage of anaerobism groove: (1) sludge concentration height, average sludge concentration is 20-40gVSS/l; (2) organic loading height is generally 10kgCOD/ (m
3D); (3) there is not the whipping device of mixing; (4) do not fill out carrier, the saving cost is also avoided because of filler generation blockage problem.
According to the utility model, but preferred peripheral hardware one settling tank 8 also of described anaerobism groove, and the mud that settling tank 8 gets off is back in the sludge blanket 6 of reaction zone 5.If the benefit of outside settling tank is: (1) accumulation of accelerate sludge but mud refluxes, shorten operation period; (2) remove suspended substance, improve effluent quality; (3) when mud taking place once in a while float on a large amount of, reclaim the stability that mud keeps technology; (4) returned sluge can be done further decomposition, can reduce surplus sludge volume.
According to the utility model, described aerobic slot 9 is bulge, and as shown in Figure 4, it has a two-phase shower nozzle 10 to be installed in the centre on aerobic slot 9 tops.Water circulating pump promotes High-Pressure Water and injects aerobic slot through shower nozzle, because suction function sucks a large amount of air simultaneously.The acting in conjunction of current and air-flow makes the shower nozzle below form high speed turbulent shear district again, and the gas dispersion that sucks is become tiny bubble.The combined sewage that is rich in dissolved oxygen after guide shell arrives the aerobic slot bottom, the formation circulation that upwards backflows again, jet under shearing again, operation so moves in circles.So sewage is by oxygenation repeatedly, bubble and microorganism cenobium are constantly sheared refinement, and form fine and close tiny flocs unit.
According to the utility model, preferably, the treated sewage of being discharged by aerobic slot top enters connected settling tank 11, and the sludge part that settling tank 11 gets off is back to the aerobic slot internal recycle and uses.
According to the utility model, preferably, the processing water after described aerobic slot 9 is handled can partly return in the described anaerobism groove 4 and use.
Embodiment
Be example with starch manufacturing process series sewage, the variation of using the utility model to handle water water quality sees Table 1.
