Abstract
The invention belongs to the field of wastewater treatment systems, and particularly relates to an infiltration ditch of a soil capillary infiltration water treatment system. The infiltration ditch comprises a cultivated soil layer positioned aboveground and an infiltration layer, a separation layer, a water distributing layer and an anti-seepage layer which are positioned underground sequentially from top to bottom, the infiltration layer is made of original soil doped with coarse sand, peat and slag, and the water distributing layer is provided with a water distributing pipe communicated with wastewater and an ozonizer communicated with ozone. The infiltration ditch of the soil capillary infiltration water treatment system is sufficient in oxygen, difficult in hardening of the soil layer and free of downward seepage of filter materials, direct downward seepage of the wastewater can be prevented, and pollutants in the wastewater can be removed stably.
Description
Technical field
The invention belongs to the Sewage treatment systems field, be specifically related to a kind of diafiltration ditch of soil capillary percolation filtration water treatment system.
Background technology
The capillary infiltration trench WWT is an a kind of representative underground sewage percolation treatment system; It is the basis with ecological principle; Utilized the natural detergent power of the Nature; Be a kind of simply, polluted water land treatment process on a small scale efficiently, be suitable for the sanitary sewage disposal of source of pollution dispersive Rural areas.Though traditional capillary infiltration trench can effectively be removed sewage; But install long operation meeting presence of oxygen QI-insufficiency, pedosphere hardens and the following problem such as leakage of filtrate; Influence the stability and the clearance of device, and then limited promoting the use of capillary infiltration trench.
Summary of the invention
The objective of the invention is to overcome the problems referred to above, provide that a kind of oxygen is sufficient, pedosphere is difficult for hardening, filtrate does not leak, prevents the directly diafiltration ditch of the soil capillary water from diffusion system of pollutent in the steady removal sewage of leakage down of sewage down.
For realizing above-mentioned purpose; The technical scheme that the present invention adopted is: the diafiltration ditch of soil capillary percolation filtration water treatment system; It is characterized in that: comprise the anthropogenic soil layer that is positioned at the face of land and be positioned at the subterranean filter layer that from top to bottom sets gradually, sealing coat, water distribution layer and impervious barrier; Described filter layer is that the primary soil that is doped with coarse sand, peat, slag constitutes, and water distribution layer is provided with water distributor that is communicated with sewage and the ozonizer that is communicated with ozone.
The diafiltration ditch of aforesaid soil capillary percolation filtration water treatment system, described cementation zone also mix mikrobe or earthworm.
The diafiltration ditch of aforesaid soil capillary percolation filtration water treatment system, described sealing coat is made up of the non-woven fabrics of porous.
The diafiltration ditch of aforesaid soil capillary percolation filtration water treatment system, described water distribution layer is made up of gravel and coarse sand.
The diafiltration ditch of aforesaid soil capillary percolation filtration water treatment system, described impervious barrier is made up of polyvinyl chloride film.
As filter layer (being main WWT layer), mikrobe can be improved wastewater treatment efficiency with the primary soil that is doped with coarse sand, peat, slag, mikrobe, earthworm in the present invention, and earthworm is shuttled back and forth in soil and keeps soil from packing together; Be arranged at the logical sewage of water distribution layer of bottom and be communicated with ozone, the even and ozone ability oxidation removal water pollutant of water distribution, ozone reduction is an oxygen, prevents that oxygen in soil is not enough; The impervious barrier that is arranged at the water distribution layer below prevents that sewage from directly leaking down; The sealing coat that is arranged between water distribution layer and the filter layer prevents to leak under the filtrate.
Description of drawings
Fig. 1 is a structure iron of the present invention;
Wherein, 1 anthropogenic soil layer, 2 filter layers, 3 sealing coats, 4 water distribution layer, 5 impervious barriers, 6 water distributors, 7 ozonizers.
Embodiment
For technical scheme, technical characterictic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with embodiment, further set forth the present invention.
The diafiltration ditch of soil capillary percolation filtration water treatment system; It is characterized in that: comprise the anthropogenic soil layer 1 that is positioned at the face of land and be positioned at the subterranean filter layer that from top to bottom sets gradually 2, sealing coat 3, water distribution layer 4 and impervious barrier 5; Described filter layer 2 constitutes for the primary soil that is doped with coarse sand, peat, slag, and water distribution layer 4 is provided with water distributor 6 that is communicated with sewage and the ozonizer 7 that is communicated with ozone; Cementation zone 2 also mix mikrobe or earthworm; Sealing coat 3 is made up of the non-woven fabrics of porous; Water distribution layer 4 is made up of gravel and coarse sand; Impervious barrier 5 is made up of polyvinyl chloride film.
As filter layer 2 (being main WWT layer), mikrobe can be improved wastewater treatment efficiency with the primary soil that is doped with coarse sand, peat, slag, mikrobe, earthworm in the present invention, and earthworm is shuttled back and forth in soil and keeps soil from packing together; Be arranged at the water distribution layer 4 logical sewage of bottom and be communicated with ozone, the even and ozone ability oxidation removal water pollutant of water distribution, ozone reduction is an oxygen, prevents that oxygen in soil is not enough; The impervious barrier 5 that is arranged at water distribution layer 4 belows prevents that sewage from directly leaking down; The sealing coat 3 that is arranged between water distribution layer 4 and the filter layer 2 prevents to leak under the filtrate.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
