Description
Technical field
The utility model relates to a kind of Rural Sustainable Development domestic sewage processing systems, belong to sewage disposal technology neck
Domain.
Background technique
With urbanization and industrialized fast development, China's water pollution is more serious, and earth's surface river is by different degrees of
Pollution, water resource is more in short supply, and simultaneously rural economy is fast-developing, and comprehensive wastewater amount discharge amount is continuously increased, without
Processing is directly discharged to water environment, keeps area surroundings worsening, seriously threatens the health of mass peasants, " water pollution row
Dynamic plan " implementation promote water prevention and cure of pollution, it is mentioned that accelerating rural environment comprehensive improvement, promote rural sewage treatment and set
It applies.And currently, China's rural domestic sewage treatment facility is not popularized also, because of more dispersed, the sewage collecting of rural area village family inhabitation
Pipe network cost is excessively high, and some flourishing village techniques with sewage treatment facility are relatively simple, is directly discharged to after processing
In the water environment of periphery, operating cost is higher, and on the other hand, after the policy for forbidding crop straw burning is put into effect, straw from village is not gone
Place is deposited in by country ditch and on road, seriously pollutes environment, restrict the development of rural economy, for rural area can
Sustainable development needs a kind of economical and practical comprehensive sewage treatment system.
Utility model content
The utility model provides one kind and rationally discards agricultural and sideline crop, no remaining dirt using stalk, the shell etc. that rural area generates

Further, described to discard agricultural and sideline crop as stalk or shell in the utility model.
The process handled using Tthe utility model system are as follows:
(1) country sewage pipe network collection sewage enters multistage septic tank, big solid organic matters the staying in excrement such as excrement first
Pond carries out anaerobic fermentation, and larger molecular organics are decomposed into small organic molecule, and generate biogas.
(2) the supernatant water outlet of multistage septic tank is flowed into grid/setting pot, and grid retains solid organic matters and suspension
Object, setting pot settle inorganic particulate matter, reduce the concentration of suspension of sewage.
(3) setting pot water outlet enters anoxic biology membrane cisterna and biological contact oxidation pond biochemical system, biological contact oxidation pond
By nitrification liquid return pipe reflux nitrification liquid to anoxic biology membrane cisterna, the most of organic matter of removal under microbial action, TN,
TP、NH4- N is largely removed, and is separated by solid-liquid separation in sedimentation basin, and supernatant enters sterilization pool, and partial sludge is returned by sludge
Flow tube flows back into anoxic biology membrane cisterna, and excess sludge is discharged to more three-level septic tank fermentations by the reflux of residual sludge reflux pipe.(4)
Thimerosal is added in sterilization pool to carry out disinfection to sewage, is eliminated bacterial viruses, the water outlets after disinfection such as Escherichia coli and is entered absorption
Filtering ponds discard agricultural and sideline crop material, shell etc. as adsorbent material, stalk and shell with irregular porous using rural area
Structure has good adsorption properties, and stalk, shell tie up blocking placement, absorbs and filter remaining organic matter, stalk, shell etc.
It manually salvages after adsorption saturation, is transported by cart 13, solution bundle, which separates, is loosely sprinkled into multistage septic tank fermentation methane production.
(5) absorption filtering pool effluent quality is more excellent, and fishery water requirement is fully achieved, and water outlet is discharged into ecological pond, ecological pond
The water surface and water-bed planting aquatic plants, build graceful landscape, and the culturing fish and shrimp in the pool is taken out after water level is higher than design water level
It takes in irrigated farmland, water resource is utilized effectively.
(6) then the biogas generated is registered one's residence, is used for villager by collection/deodoration system purification.
It is directly discharged into river after the existing big multiprocessing of processing system is up to standard, excess sludge is more, in addition pipe network early period is put into, agriculture
Village's sewage treatment comprehensive cost is higher, the rural sewage treatment system of the utility model, rationally cleverly using causing rural area dirty
Stalk, the shell of dye constitute filtering ponds, and stalk and shell are porous structure, and absorption property is good, waste utilization, improve sewage treatment
Effect, and enter septic tank after adsorption saturation and ferment, secondary use is carried out, biogas is generated, not will cause secondary pollution, solves agriculture
Village's environmental pollution, water outlet generates Water Resources Value, biogas can create economic value, this is one kind for cultivating, irrigating after processing
Ecological sustainability system.
The utility model is a kind of Rural Sustainable Development domestic sewage processing system, and operating cost is low, side easy to operate
Just, agricultural and sideline crop rationally is discarded using stalk, the shell etc. that rural area generates, while low in cost, the ecology for solving rural area is dirty
Dye problem, processing system are generated without excess sludge, be can produce biogas and are used for villager, and water outlet is for culturing fish and shrimp, filling after processing
Farmland is irrigate, considerable economic value is created, is the sustainable development domestic sewage processing system suitable for rural area.
