Abstract
The invention discloses a kind of domestic sewage in rural areas purification process technique；Comprise the following steps：1) domestic sewage in rural areas is introduced into grille well, buried anaerobic digester is entered after grille well filters；2) water after buried anaerobic digester processing enters the aerobic filter bed of microkinetic, 3) water after the aerobic filter bed processing of microkinetic enters biofilter, 4) water after biofilter is filtered enters artificial swamp, and kind is equipped with wilson iris in the artificial swamp；5) water after artificial wetland treatment enters ecological pond, the Chinese effluent after ecological pond is handled to natural water.This method is suitable to scattered rural area village and treatment effect is stable, foul smell can be greatly reduced distributes and mosquitos and flies grows.
Description
Technical field
The present invention relates to a kind of domestic sewage in rural areas purification process technique, belong to field of environment engineering technology.
Background technology
With the fast development of rural economy, rural comprehensive wastewater discharge gradually increases, and makes rural area environmental aspect
Worsening, environmental quality are decreased obviously, and are directly threaten the living environment and health of the vast farmerses masses, are constrained agriculture
The sound development of village's economy.Arbitrarily discharge is the main reason for causing Rural Water Environment to pollute, seriously to pollute agriculture to sanitary sewage
The ecological environment in village, directly threaten the health of the vast farmerses masses and the economic development in rural area.
China's domestic sewage in rural areas has following characteristics：(1) disperse, distribution area it is big.The scattered Characteristics of Geographical Distribution in village
Sewage is caused to disperse, it is difficult to collect.(2) it is wide to carry out source range.In addition to from sewage caused by human faecal mass, kitchen, also family
Cleaning, house refuse, which are stacked, to be percolated and caused sewage.(3) treatment effeciency is low.Existing statistics shows at present, the life of China rural area
The handling rate of sewage living is only 12.9%.
The treatment technology that domestic and international application domestic sewage in rural areas is administered at present is relatively more, and title is also varied, but no matter
It is that nature processing system or biological treatment system all have the problem of technology is single, treatment effect is unstable, while handles model
Enclose also restrained, easy emitting offensive odor and growth mosquitos and flies.
The content of the invention
It is an object of the invention to provide a kind of domestic sewage in rural areas purification process technique.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of domestic sewage in rural areas purification process technique, comprises the following steps：
1) domestic sewage in rural areas enters the ditch for carrying fine fack or irrigation canals and ditches, water are by the flow velocity in ditch or irrigation canals and ditches
0.5-0.7m/s, water are 0.6-0.8m/s by the flow velocity of fine fack, manual cleaning grid slag, are removed through fine fack pretreatment thick
Domestic sewage in rural areas after particulate matter flows into buried anaerobic digester；
2) the hydraulic detention time 10-24h in buried anaerobic digester, sludge caused by buried anaerobic digester
2-3 is cleared up 1 time, and the sludge cleared is applied as organic agriculture fertilizer；
3) it is good into microkinetic after buried anaerobic digester removes partial organic substances and the biodegradability for improving waste water
Oxygen filter bed, the aerobic filter bed dissolved oxygen concentration of microkinetic is 2-4mg/L, sets supporting layer at 20-30cm above away from distribution device,
A diameter of 10mm round vent is evenly arranged on supporting layer, the centre distance of adjacent holes is 40-50mm, on supporting layer top
Filler is set, and filler is building stones, sand, the mixture of haydite, and waste water is 8- in the hydraulic detention time of the aerobic filter bed of microkinetic
12h；
4) water after the aerobic filter bed processing of microkinetic enters biofilter, is filtered in the biofilter filled with hairbrush elasticity
Material, corrugation 160~200mm of filament length of the hairbrush elastic filter material, a diameter of 2~5mm of silk；
5) water after biofilter is filtered enters vertical current constructed wetland, the matrix of the artificial swamp it is bottom-up according to
It is secondary for particle diameter 50-100mm boulder bed, particle diameter 15-30mm volcanic rock filter material layer, particle diameter 8-10mm cinder layer and particle diameter
0.2-5mm's is equipped with wilson iris and eel grass without mud coarse sands layer, the interior kind of the artificial swamp；
6) water after artificial wetland treatment enters ecological pond, and the water in artificial swamp persistently flows back to biofilter；Institute
State kind in ecological pond and be equipped with lotus, hornwort and water lily, the Chinese effluent after ecological pond is handled to natural water.
Further, the biofilter is supplied oxygen by being arranged on multiple aeration heads of bottom.
Further, described buried anaerobic digester uses brick or concrete structure, buried anaerobic digester
To be spherical.
Further, described distribution device is hole membranes gas pipe or micropore ceramics gas pipe..
Beneficial effects of the present invention：The present invention handles domestic sewage in rural areas by the group technology of artificial swamp, ecological pond,
Not only high treating effect, secondary pollution are small, and overcome the shortcomings that traditional treatment method cost is high, and it is invested, safeguards and transported
Row expense is low, is especially suitable for the relatively small rural area of the density of population, and operating cost is low.
