Description
Technical field:
The utility model relates to water process ecological device, it is specifically designed for rural households' sanitary sewage and dispersion cultivation is useless
Water and rainwater-collecting processing ecological device, the ecological device be suitable for semi-moist, arid area, warm temperate zone area, hills or
Mountainous region area, is also applied for the rural area distributing garden that plains region can not be grid-connected.
Background technique
With the raising of the continuous development of China's rural economy and life of farmers level, domestic sewage in rural areas discharge amount per capita
Increase year by year；Due to rural resident's inhabitation relative distribution, sewage network is difficult to cover all rural households, especially some hills
With mountainous region area；The idle waste of large amount of sewage treatment facility, realistic situation is that sanitary sewage direct emission is still universal, serious shadow
The living environment in rural area is rung, the discharge of sewage also results in the increase of river loads of nutrition, lake eutrophication.
Currently, the treatment process and technology of country sewage have focused largely on village life production waste centralized processing (patent
Number 104926038 B of CN), disadvantage is as described above: first is that being difficult to cover all peasant households, second is that since the shortage of capital has been difficult to
Effect operation.Dispersibility is less with the technology that family is processing unit, mainly some bilge wells and septic tank technique.Though bilge well
So management is simple, and cost is low, but the pollution that can cause underground water is used for a long time；Septic tank is the disadvantage is that often there is peculiar smell row
Out, not only scarfing cinder is complicated, but also influences beautiful.
On the other hand, beautiful rural construction is related to new rural village landscape planting, increases water demand, opposite in water resource
The northern area of shortage, technology of middle water recycle application is also more and more extensive similar with sewage disposal technology, technology of middle water recycle
It is concentrated mainly on villages and small towns centralized processing, the technology of middle water recycle for being related to single rural households is relatively deficient.
Utility model content
The purpose of this utility model is to provide a kind of sanitary sewages as unit of single rural households and dispersion to support
The processing unit for growing waste water, sewage treatment and technology of middle water recycle are combined, and it is dirty to solve sparsely populated rural household's life production
Water discharges problem that can not be grid-connected；Solves the demand of China shortage of water resources area countryside family landscape planting water；Simultaneously
It solves the problems, such as peculiar smell discharging again, has combined landscape ecologic function；Sewerage ecological pool project, scale are concentrated with village
It is small, facilitate management, it is easy to operate, it is time saving and energy saving.By the implementation of the technology, single rural households not only may be implemented to live
With the zero-emission of breeding wastewater, water source also is provided for rural households' landscape planting.This technology is in following new countryside construction
