Description
Technical field
The present invention relates to environmental technology field; Be a kind of dispersant type domestic wastewater source separating treatment and method of resource, water polluted control, can carry out the source to dispersant type domestic wastewater and separate, handle and resource utilization; Effective reduce water consumption makes the sewage after the processing reach reuse standard.
Background technology
For many years, the center of gravity of China environmental protection work is the city always, and the geographic problem of environmental pollution of rural area and scattered settlement is the blind spot or the dead angle of polluting the control field at present.China's rural area ubiquity sewage collecting pipe network is unsound, the incomplete characteristics of sewage treatment facility, and fecal sewage and other domestic waters be without dealing carefully with, and arbitrarily discharges or permeate the ground contaminate environment; The dirty interflow of rain in rainy season gets into the river course, and water surrounding is worked the mischief.
The current processing for decentralized type sewage mainly adopted land treatment system and integrated Small Sewage Treatment Equipment.Like Chinese patent: a kind of in-site ecological purifying method (200710023435.8) of decentralized wastewater, handle sewage high-load capillary infiltration trench system (200810018744.0), handle rural decentralized wastewater high-load angleworm bio-filter (200810201392.2), utilize high-load angleworm bio-filter to handle the method (200810201394.1) etc. of rural decentralized wastewater.Be characterized in domestic sewage in rural areas by using is collected small-sized treatment unit such as getting into land treatment system or biological filter, reach the purpose of disposing of sewage.But there are some drawbacks in these technology because with Heisui River (human excrement) and buck (bath water, kitchen water) mixed collection aftertreatment: 1, because sewage source is complicated, the sewage mixed collection makes that the sewage quality change is bigger, influences system's operation stability.2, the organic loading in Heisui River and pathogenic bacteria load is all higher, mixes the burden that has increased WWT with buck, makes that also the nutritive substance in the Heisui River is difficult to reclaim.3, buck combination treatment in Heisui River makes sludge quantity increase, and disposes, safeguards inconvenience, is difficult to long-acting operation.4, above-mentioned technology still rests on the pollution control aspect to sewage, the recycle of nutritive substance and effluent reuse in the sewage of being unrealized.Know that by above from improving the angle of processing efficiency, Heisui River, buck separate treatment must have that technology is simple, reduced investment, advantage that working cost is low.Therefore the exploitation system process that can realize separating from the sewage source, handle resource utilization effectively utilizes to have with water resources for the dispersant type domestic wastewater control in the vast rural area of China and uses and promotional value.
Summary of the invention
The objective of the invention is to disclose a kind of dispersant type domestic wastewater source separating treatment and method of resource,, and improve the human settlement with the effective problem of utilizing again of processing, control and water resources that solves China's vast rural area dispersant type domestic wastewater.
For achieving the above object, technical solution of the present invention is:
A kind of dispersant type domestic wastewater source separating treatment and method of resource, it comprises step:

Embodiment
The many villages and small towns of China do not have sewage treatment facility or facility to fall behind now, and the pollution problem of domestic sewage of villages and small towns never is effectively controlled.The inventive method has designed a cover decentralized type sewage source separating treatment process system according to the source and the characteristics of current practical situation and sewage.Its principle is to utilize vacuum excrement collector to realize that Heisui River, Ash Water Separator collect, and Heisui River, buck are handled respectively, and the nutritive ingredient in the recycle Heisui River makes the buck after the processing reach reuse standard simultaneously.
A kind of dispersant type domestic wastewater source separating treatment of the present invention and method of resource, form by three systems:
1 sewage source separated collection system: the villages and small towns resident living water is collected by two circuits, and a circuits is collected Heisui River, is that the negative pressure of vacuum of utilizing vacuum excrement collector to produce is collected Heisui River; Each flushing water loss is merely 1/10th of conventional toilet; Be about 0.5 liter (traditional lavatory 5-6L/ time), effectively reduce water consumption significantly reduces the Heisui River amount simultaneously; And used pipeline caliber is merely 50cm, and it is very convenient to construct.Another set of piping system is then collected buck.Thereby realize the separated and collected of Heisui River, buck.
2, Heisui River grey water treatment system: the Heisui River that vacuum excrement collector is collected gets into ferment tank, and it is agricultural to can be used as organic fertilizer after waiting to ferment.And the buck of collecting gets into grey water treatment system, and this system is made up of pre-treatment and land treatment system (like wetland, oxidation pond etc.).Because system's water inlet is buck, organic loading is much littler than combined sewage, so the land treatment system area also can reduce significantly.
3, Heisui River, grey recycling of water resource system: treated Heisui River, buck can realize that all resource utilization utilizes again.Therefore can be used as fertilizer behind the fermenting-ripening of Heisui River, the buck after the processing can reach reuse standard, all can be in the farmland, vegetable plot, garden etc. realize cycling and reutilization.
In order to introduce technology of the present invention in more detail, explain below in conjunction with examples of implementation:
Embodiment 1:
With a kind of dispersant type domestic wastewater source separating treatment of the present invention and method of resource, be applied to Tan Dang village, Xinzhuang Town, Changshu City, Jiangsu Province one peasant household at present.The four-hole people of this peasant household, new house is a three-storey building, every floor all is equipped with conventional toilet.Flower bed and fish pond are arranged before the room, garden and vegetable plot are arranged behind the room.All sewage that produce get into the irrigation canals and ditches of water drain without the in line next door of any processing.
At first, the water closet of this peasant household is replaced by the vacuum economical toilet, lays Heisui River and collect pipeline.Original waste pipe is as grey water collection pipe road.So just, can realize Heisui River, Ash Water Separator is collected.Secondly, isolating sewage gets into Heisui River through the source, grey water treatment system is handled respectively.Heisui River after the processing, ash water recycling be in the vegetable plot, and the resource utilization of sewage is realized in the garden.Total system has realized the closed cycle of nutritive substance in the sewage, has controlled the pollution of sewage to environment.
