Description
Technical field
The utility model relates to the technical field of sanitary sewage disposal, is specifically related to a kind of anaerobic reactor for sewage reuse.
Background technology
Internal-circulation anaerobic reactor (internalcirculationreactor, IC) is Dutch PAQUES company in 20th century the mid-80 succeed in developing on the basis of UASB reactor the 3rd generation ultra-high efficiency anaerobic reactor.By 1988, the IC reactor of First productivity scale put into operation in Holland in the world.Due to high, the less investment of its process capacity, occupation of land economize, the feature such as stable, cause attracting attention of various countries' water treatment personnel, one of representative technique for third generation anaerobic biochemical reactor that someone looks.Up to the present, the production waste being successfully applied to the industries such as beer production, papermaking, food-processing, citric acid administer further research and development IC reactor, promote its range of application and become one of focus of waste water fermentation process, but also there are some restricted shortcomings, when Biodegradability of Wastewater is not very good, because the shorter pollutants removal rate of hydraulic detention time is lower, water outlet Pollutant levels are higher, add the burden of follow-up Aerobic Pond.In addition, IC, due to gas internal recycle, particularly to the factory of influent quality less stable, causes IC water outlet water yield extremely unstable, and effluent quality is also relatively unstable, and sometimes also may there will be of short duration not water outlet phenomenon, be influential to postorder treatment process.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of anaerobic reactor for sewage reuse, is located at outside anaerobic reactor by pipeline, add the useful space of inside reactor, return line simplicity of design, easy controlled circulation amount.
For achieving the above object, the technical scheme that the utility model is taked is:
A kind of anaerobic reactor for sewage reuse, comprise main body, it is characterized in that: described main body is divided into mixing zone from the bottom up successively, first anaerobic zone, second anaerobic zone, settling region, gas-liquid separation zone, described lower end, mixing zone is provided with water-in, the first described anaerobic zone and the second anaerobic zone are respectively equipped with the first return line and the second return line, the first described anaerobic zone and the second anaerobic zone are also respectively equipped with the first biogas pipe and the second biogas pipe, described settling region is provided with water outlet, described upper end, gas-liquid separation zone is provided with firedamp drainage mouth, lower end is provided with return line, the first described return line and the second return line all downward-sloping and interflow lead to mixing zone.
As preferably, the first described return line, the second return line, the first biogas pipe, the second biogas Guan Jun are located at outside main body.
As preferably, described return line leads to mixing zone bottom gas-liquid separation zone.
As preferably, the first described biogas pipe and the second biogas pipe collaborate and lead to gas-liquid separation zone.
A kind of anaerobic reactor for sewage reuse described in the utility model, compensate for the deficiencies in the prior art, is located at by pipeline outside anaerobic reactor, add the useful space of inside reactor, return line simplicity of design, easy controlled circulation amount.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and example, the utility model is described further.
As shown in the figure, a kind of anaerobic reactor for sewage reuse, comprise main body, it is characterized in that: described main body is divided into mixing zone 102 from the bottom up successively, first anaerobic zone 104, second anaerobic zone 110, settling region 106, gas-liquid separation zone 108, described lower end, mixing zone 102 is provided with water-in 101, the first described anaerobic zone 104 and the second anaerobic zone 110 are respectively equipped with the first return line 112 and the second return line 111, the first described anaerobic zone 104 and the second anaerobic zone 110 are also respectively equipped with the first biogas pipe 103 and the second biogas pipe 105, described settling region 106 is provided with water outlet 109, described upper end, gas-liquid separation zone 108 is provided with firedamp drainage mouth 107, lower end is provided with return line 113, the first described return line 112 and the second return line 111 all downward-sloping and interflow lead to mixing zone 102, the first described return line 112, second return line 111, first biogas pipe 103, second biogas pipe 105 is all located at outside main body, described return line 113 leads to mixing zone 102 bottom gas-liquid separation zone 108, the first described biogas pipe 103 and the second biogas pipe 105 collaborate and lead to gas-liquid separation zone 108.
During real work, sewage is injected device mixing zone anyway by water-in, now, water, the mud mixture of granule sludge and gas-liquid separation zone backflow mixes in this district effectively, the mud mixture that mixing zone is formed enters the first anaerobic zone, under high concentration sludge effect, major part organism is converted into biogas, the violent disturbance of mixed solution upwelling and biogas makes mud in this reaction zone be expand and fluidized state, strengthen muddy water surface contact, mud remains high activity therefrom, along with increasing of biogas output, part mud mixture is promoted to the gas-liquid separation zone at top by the first biogas pipe, and mud gets back to mixing zone by the first return line, mixed solution through the first anaerobic zone enters the second anaerobic zone again, this district's sludge concentration is lower, and most of organism is degraded in the 1st anaerobic zone in waste water, therefore biogas generation is less, but still have a small amount of biogas to enter gas-liquid separation zone through the second biogas pipe, and mud gets back to mixing zone by the second return line, finally enter settling region through the mixed solution of 2 anaerobic reactions to precipitate, top clear water is discharged by water outlet, the granule sludge of precipitation sinks to the second anaerobic zone, the biogas that first biogas pipe and the second biogas pipe promote enters gas-liquid separation zone and is separated, biogas after separation is discharged by firedamp drainage mouth, mud mixture then turns back to mixing zone bottom along return line, fully mix with intaking with the mud of reactor bottom, achieve the internal recycling of mixed solution.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., be all included within protection domain of the present utility model.
