Background technology
Hydraulic and Hydro-Power Engineering floods soil, causes immigration relocation, needs to carry out Relocation and Settlement to immigrant, for the engineering that some immigrant's numbers are more, often needs to build some resettlement of affected residents market towns or concentrated settlement.Because large water conservancy hydroelectric engineering is generally within mountain area, resettlement of affected residents market town is often flooded more than water level in reservoir area and is selected nearby, if do not processed the sanitary sewage that it produces, will pollute reservoir area water quality, therefore must process immigrant's town domestic sewage, discharge after reaching respective standard.
To the process of resettlement of affected residents town domestic sewage, in prior art, there is kinds of schemes such as adopting septic tank, methane-generating pit, artificial swamp, integrated facility.Septic tank process sanitary sewage only can reach " integrated wastewater discharge standard " (GB8978-1996) grade III Standard, does not meet direct emission request; Area needed for artificial swamp is comparatively large, and some larger immigrant market town exists the problem of land used difficulty, is not suitable for artificial wet land treating method; Methane-generating pit operational management requires higher, and maintenance cost is also higher, is not suitable for life-time service; Adopt integrated facility can reach good effect, but there is its singularity in immigrant market town compared with cities and towns, sewage generation is little, drain time Relatively centralized, need intermittent type process, and inorganics is less, and often professional operational management is undermanned.
Utility model content
In order to solve the problem, the utility model provides a kind of resettlement of affected residents town domestic sewage treatment system, can reach first discharge standard, protection reservoir area water quality, simultaneously can intermittent type process sanitary sewage, and the running maintenance personnel of needs are few, floor space is little.
The utility model is achieved by following technical solution.
A kind of resettlement of affected residents town domestic sewage treatment system, comprise septic tank, grating tank, preaeration equalizing tank and buried type integrated equipment, described septic tank, grating tank, preaeration equalizing tank, buried type integrated equipment connect successively; Described buried type integrated equipment comprises anaerobic biological treatment pond, Aerobic biological process pond, sludge digestion tank, second pond and sterilization pool, one end, described anaerobic biological treatment pond is communicated with preaeration equalizing tank by sewage pump, and the other end connects aerobic biological treatment tank, second pond and sterilization pool successively.
Further, described sludge digestion tank is communicated with anaerobic biological treatment pond, and is connected with second pond.
Further, described Aerobic biological process pond is communicated with anaerobic biological treatment pond and forms loop.
Further, described buried type integrated equipment is also provided with fan house outward, and is communicated with preaeration equalizing tank, anaerobic biological treatment pond, Aerobic biological process pond by aeration tube simultaneously.
Further, described preaeration equalizing tank top is provided with manhole.
Further, described anaerobic biological treatment pond and the plastic honeycomb inclined tube filler being provided with vertical placement in aerobic biological treatment tank.
The beneficial effects of the utility model are:
A kind of resettlement of affected residents town domestic sewage treatment system described in the utility model; by anaerobic biological treatment pond, Aerobic biological process pond, settling tank, sludge digestion tank, sterilization pool are arranged in close-coupled processing facility inside; be embedded in underground; only need on the ground to build Ventilator Room; save and take up an area; to ground environmental nonpollution, solve Zone of Arranging Immigration sanitary sewage disposal problem, protection reservoir area water quality.Working process both controlled to control the nodes such as the time of sewage disposal to pipeline valve by artificial, implemented to control again by automation system, had laid technical foundation for realizing unmanned control completely in the future; And for the less resettlement of affected residents market town of population size or concentrated settlement, native system can also periodic running, to realize its scientific and effective utilization, extend the bulk life time of system.
