Abstract

The utility model relates to an underground integrated device for treating domestic sewage and generating biogas, which belongs to the environmental purifying equipment field, in particular to a biogas generation and domestic sewage treatment device. The integrated device comprises an anaerobic fermentation tank and a filter tank, wherein the anaerobic fermentation tank is equipped with a sewage inlet and a biogas outlet. The filter tank comprises an anaerobic biological filter tank and/or an aerobic biological filter tank and an aerobic biological baffling filter ditch, a baffling wall is arranged in the baffling filter ditch, the lower portion of the end of the baffling wall is equipped with an outlet of purified water, the upper portion is equipped with an outlet of residual biogas, a liquid connecting pipe is arranged on the lower portion between the fermentation tank and the filter tank which are adjacent , and a gas connecting pipe is arranged on the upper portion of the two adjacent filter tanks. The integrated device utilizes an underground design, therefore the investment is less, the ground and surface space are not occupied, the device is simple and easy in operation, high in efficiency and can save energy, thereby not only the biogas is generated but also the sewage is purified. The integrated device is an environment-friendly purifying treatment device which innocently treats and reuses fecal sewage and domestic sewage.

Description

A kind of buried processing sanitary sewage and generation biogas integrated apparatus

Technical field

A kind of buried processing sanitary sewage of the utility model and generation biogas integrated apparatus belong to the environmental protection purifying equipment field, are specifically related to biogas and take place and sewage treatment unit.

Background technology

At present, at the extensive methane-generating pit class biogas generating device that adopts in vast rural area and samll cities and towns, be to utilize solid-state or liquid dirt, in methane-generating pit, handle the biogas generating device of a kind of simple function that produces biogas through anaerobically fermenting, and the small-sized sewage treatment unit of current extensive employing, no matter adopt which kind of treatment process, it also is the purifying domestic sewage treatment unit of simple function, so far, at the purifying treatment industry field of ight soil and sanitary sewage, do not see to have to have the treatment unit that produces the biogas and the double function of disposing of sewage concurrently.

The utility model content

The purpose of this utility model provides a kind of buried processing sanitary sewage and the biogas integrated apparatus takes place, outside municipal sewage pipe network, innoxious, the recycling treatment that adopt this device that dispersive dwelling house sanitary sewage in the setting range and public lavatory fecal sewage are concentrated, to improve the undesirable condition of sewage discharge, make and reach " decontamination of human excreta hygienic standard " GB7959-87 and " integrated wastewater discharge standard " GB8978-1996, thereby enabling environment, favourable general health helps resource recycling.

The utility model purpose is achieved by the following technical solution:

Buried processing sanitary sewage of the utility model and generation biogas integrated apparatus, comprise anaerobically fermenting pond and filtering basin, it is characterized in that there are sewage inlet 1-1 and methane outlet 1-2 in anaerobically fermenting pond 1, filtering basin are by anaerobe filtering basin 2 and/or aerobe filtering basin 3, the aerobe baffling filters ditch 4 and forms, be provided with the filler 5 that contains active bacterium mud in the anaerobe filtering basin 2, be provided with aerobic stone filtering layer 6 in the aerobe filtering basin 3, the aerobe baffling filters in the ditch 4 aerobic stone filtering layer 7 and deflected current wall 8, filter ditch 4 ends at the aerobe baffling treated water outlet 9 and remaining methane outlet 10 are arranged, at fermentation vat, fluid connection pipe 11 is arranged at the bottom between adjacent two ponds of filtering basin, and air communicating pipe 12 is arranged at top between adjacent two filtering basin.

The integrated apparatus that the utility model is handled sanitary sewage and generation biogas is buried design, adopt the reinforced concrete structure, less investment, do not take up an area of face and spatial surface, simple to operate, simple and easy to do, energy-conservation, efficiently, can disperse the fecal sewage of unordered discharging and sanitary sewage to put together with outside the sewage network, after the processing of this integrated treatment unit, providing the energy with the biogas that produces within the specific limits by pipeline, the water after the purifying treatment is recycled or discharging on request, is a kind of environmental purification treatment unit of sewage is innoxious and resource utilization.

Embodiment

How now further specify the utility model in conjunction with the accompanying drawings implements:

The setting of the integrated apparatus of biogas also takes place in the buried processing sanitary sewage of the utility model, is mainly used in the geographic sewage disposal of not building B-grade sewage treatment plant.As required, outside this area's sewage network, fecal sewage and other sanitary sewage to residential neighborhoods, office building, public place etc. are handled, to improve the undesirable condition of sewage discharge, make it to reach " decontamination of human excreta hygienic standard " GB7959-87 and " integrated wastewater discharge standard " GB8978-1996, enabling environment not only, favourable common people's health, and help resource and reclaim.The utility model device adopts buried reinforcing bar to mix clay structure, the meet the demands requirement of " Code for design of building water supply and sewerage " GBJ5-88, " Code for design of outdoor sewerage engineering " GBJ14-87, " Code for design of masonry strucres " GBJ3-88 and " Code for design of concrete structures " GBJ10-84 of this apparatus structure.

This device builds up when implementing to use, fecal sewage and sanitary sewage delivery pipe and anaerobically fermenting pond inlet 1-1 are tightly connected, sewage ferments in fermentation vat 1, the biogas that the fermentation back takes place is exported from methane outlet 1-2, use for the user by connecting pipeline, by fermentation sewage flows into anaerobe filtering basin 2 by fluid connection pipe 11 in the fermentation vat 1, be provided with in the anaerobe filtering basin 2 sell on the market biofilter material 5, be that the polypropylene filler adds active bacterium mud, effect by the active bacterium of biofilter material in the anaerobe filtering basin 2, main organic dirt is promptly destroyed and removes by the active bacterium of anaerobism in the sewage, filtering water enters aerobe filtering basin 3 through this pond, by aerobic stone filtering layer 6 in this pond, further destroy and remove all the other organism in the water by aerobic microbiological, make clarification of water, in order in the filtering basin of finite length, to improve filtration efficiency, filter ditch 4 through aerobe filtering basin 3 filtering water through entering the aerobe baffling communicating pipe 11, the aerobe baffling filters in the ditch 4 and not only is provided with aerobic stone filtering layer 7, also has deflected current wall 8, the existence of deflected current wall 8, effectively increase the water liquid that is filtered and in the filtration channel of certain-length, stopped filter time, improved filtration efficiency, so far, reach " decontamination of human excreta hygienic standard " GB7959-87 and " integrated wastewater discharge standard " GB8978-1996 through above-mentioned treated water, can discharge from water outlet 10, suitably utilize, perhaps enter municipal water and handle webmaster, 9 dischargings of the remaining biogas of minute quantity from the air outlet.

In the relatively low place of pending concentration of wastewater, can omit anaerobe filtering basin 2, by fermentation sewage can be directly enters aerobe filtering basin 3, enters the aerobe baffling then and filter ditch 4 by fluid connection pipe 11 in fermentation vat 1, carry out aforesaid processing, and reach the relevant criterion requirement.

This device volume specification and the fermentation vat, anaerobe filtering basin and the aerobe filtering basin quantity that adopt side by side, sewage quantity, the waste concentration that should produce every day with set zone leveling be foundation, suit measures to local conditions, and take all factors into consideration to design and implement.
