Description
Technical field
The utility model relates to a kind of distributing country sewage soil filtration purification devices, belong to sewage disposal technology neck
Domain.
Background technique
With the development of rural economy, rural area living standard is continuously improved, and Development of China's Urbanization also constantly promotes, therefore
Requirement to living environment is also higher and higher.Meanwhile the discharge amount of domestic sewage in rural areas is also continuously increased.China city at present
Wastewater treatment rate has had reached certain level, but the sanitary sewage disposal of rural area is also almost blank.For a long time,
It lacks of capital and due to administering to the thin of Rural Water Environment protective awareness, the sanitary sewage of rural area is unprocessed just directly
One of the main reason for discharge, sanitary sewage that is unprocessed or dealing with improperly has become surface water body water quality deterioration.
The processing technique of country sewage is mainly centralized collection, centralized processing mode at present.Due to most of country residents
Dispersion, pipe network are collected difficult, and hypsography is larger, are influenced by operating cost is high, transport environmentally friendly process matched therewith well
Row, causes the idleness of equipment and waste, centralized collection, the scheme of centralized processing are hardly resulted in and carried out and implemented.
Utility model content
The technical issues of the utility model solves is to be influenced by operating cost is high, country sewage is difficult to realize at concentration
Reason, environmentally friendly process matched therewith cause the idleness of equipment and waste there is no running well.
The technical solution of the utility model is to provide a kind of distributing country sewage soil filtration purification device, the device
Including adjusting preliminary sedimentation tank, anaerobic fermentation pond, solid-liquid separation tank and the soil filtration unit being sequentially communicated (by water (flow) direction)；It is described
Soil filtration unit is followed successively by surface layer layer of plants from top to bottom, planting soil layer, water distribution pipe layer, filter layer, separation layer, goes out
Water collection pipe layer, impervious barrier.
The major function for adjusting preliminary sedimentation tank is to carry out water quality and quantity adjusting, the biggish solids of specific gravity and is posted herein
The objects such as infested ovum precipitate, and can be divided by being adjusted the processed sewage of preliminary sedimentation tank by three layers: paste excrement skin, more clear excrement
The excrement slag of liquid and solid-like.
Upper layer liquid manure, from anaerobic fermentation pond is flowed into, swims in excrement skin above and is deposited on bottom surface through the adjusting preliminary sedimentation tank
Excrement slag then stay in the adjusting preliminary sedimentation tank and continue to ferment.It is thin using the anaerobism being attached on floating stuffing in institute's anaerobic fermentation pond
Bacterium carries out fermentation decomposition to the polluter in sewage, and worm's ovum continues to sink, and pathogen is gradually dead, and sewage obtains further
Innoxious, the excrement skin and excrement slag thickness of generation are substantially reduced than adjusting preliminary sedimentation tank.
Preferably, floating stuffing is set in the anaerobic fermentation pond.
Preferably, the adjusting preliminary sedimentation tank, anaerobic fermentation pond, solid-liquid separation tank use integrated design.For integration
Adjusting preliminary sedimentation tank, anaerobic fermentation pond and the solid-liquid separation tank of design, material use glass fibre reinforced plastic structure, and unpowered equipment is not required to transport
Row maintenance.
Preferably, three phase separator is set in the solid-liquid separation tank.
Three phase separator, manual inspection hole, effluent weir are set in solid-liquid separation tank.Sewage from the contact anaerobic fermentation vat from
The solid-liquid separation tank is flowed into, liquid manure is generally decomposed at this time, and wherein germ and parasitic ovum are killed substantially.The solid-liquid
The function of separate tank mainly realizes that sludge is separated from water.
Preferably, overflow weir is arranged in the water outlet of the solid-liquid separation tank.
Preferably, the upper layer of the filter layer is the mixed layer of soil and fine sand, and lower layer is coarse sands layer.
Set in soil filtration unit water distribution pipe, surface layer planting soil, surface layer plant, water distribution pipe layer, filter layer,
Separation layer, effluent collection tube layer, impervious barrier.Sewage enters soil filtration unit through the solid-liquid separation tank, above filter tank by compared with
Fertile planting soil composition, plants the plants such as flowers and plants and crops thereon, realizes sewage greenery patches, can sufficiently remove in sewage
Organic matter, pathogen etc..Filter layer upper layer is that local soil admixes fine stone, and lower layer is coarse sand, strengthen soil reduction process environment,
Promote soil denitrification process, is the main function layer of sewage purification.
The dress can be set using integrated modular, factory's customization, easy to transportation and installation, be saved floor occupying area and cost of investment,
Device is suitable for distributing domestic sewage in rural areas (4 ~ 6 families or 2m3/ d).Physics, chemistry and biological cleaning through the purification device
Deng the water outlet after complicated ecological purification process, water quality can reach " urban wastewater treatment firm pollutant emission standard "
(GB18918-2002) secondary standard water quality indicator.
The beneficial effects of the utility model are:
(1) preposition anaerobic system and precipitation unit can reduce subsequent soil filtration pond processing load, also can be reduced filter tank
Blocking, have higher guarantee compared to single Process for Effluent.
(2) soil filtration unit (soil filtration pond) combines the dual function in wetland variation and filter tank.Filter tank is in ground
There is down certain insulation effect, it is made still to be able to maintain preferable treatment effect in winter.
(3) solid-liquid separator goes out to flow using three phase separator and weir formula, guarantees that water outlet SS concentration in combination pond maintains lower water
It is flat, it further reduced subsequent soil filtration pond blocking risk.
(4) contact-oxidation pool uses floating stuffing, relative to hanging filler, convenient for drawing maintenance clearly.
(5) cancel aeration link, technological design realizes unpowered operation, later period operation maintenance letter without mechanical moving element
It is single, it is nearly free from operating cost, annual periodic maintenance 2 times is suitble to the sewage treatment demand of rural area dispersion resident.
(6) can be used modularized design, production is simple, and adaptation to local conditions can be optionally combined, installation and transportation are convenient, invest at
This is low.
