Description

Treatment method for rural sewage
Technical field
The present invention relates to a kind for the treatment of method for rural sewage, belong to technical field of sewage.
Background technology
With the fast development of rural economy, rural comprehensive wastewater discharge gradually increases, and makes rural area environmental aspect Go from bad to worse, environmental quality is decreased obviously, directly threaten the living environment of the vast farmerses masses with it is healthy, constrain agriculture The sound development of village's economy.Arbitrarily discharge is the main cause for causing Rural Water Environment to pollute, severe contamination agriculture to sanitary sewage The ecological environment in village, directly threatens healthy and rural area the economic development of the vast farmerses masses.
China's domestic sewage in rural areas has following characteristics:(1)Dispersion, distribution area are big.The scattered Characteristics of Geographical Distribution in village Sewage is caused to disperse, it is difficult to collect.(2)Carry out source range wide.In addition to the sewage produced from human faecal mass, kitchen, also family The sewage that cleaning, house refuse are stacked diafiltration and produced.(3)Treatment effeciency is low.Existing statistics shows that China rural area is given birth at present The handling rate of sewage living is only 12.9%.
The treatment technology that current domestic and international application domestic sewage in rural areas is administered is relatively more, and title is also varied, but no matter It is that nature processing system or biological treatment system all have that technology is single, treatment effect is unstable, while processing model Enclose also restrained, easy emitting offensive odor and grow mosquitos and flies.
The content of the invention
The invention solves the problems that technical problem is:Overcome the shortcoming of above-mentioned technology, there is provided one kind is suitable to scattered rural area village And treatment effect stabilization, can be greatly reduced foul smell distribute with mosquitos and flies grow sewage water treatment method.
In order to solve the above-mentioned technical problem, technical scheme proposed by the present invention is:A kind for the treatment of method for rural sewage includes Following steps:
1)Domestic sewage in rural areas is introduced into grille well, domestic sewage in rural areas is introduced into grille well, entered after being filtered through grille well and expose Gas pond;
2)The water outlet of aeration tank enters sedimentation basin, and the water outlet of sedimentation basin enters facultative lagoon;
3)Water after facultative lagoon treatment enters biofilter, the bullet being made filled with macromolecule organic material in the biofilter Property filtrate, its porosity be 75~98%, aperture be 6~8mm, specific surface area be 10~35m2/g;
4)Water after being filtered through biofilter enters tube-shaped electrolyte groove, and the tube wall of the tube-shaped electrolyte groove is anode, and negative electrode is in post Shape, at the axis of tube-shaped electrolyte groove;
5)The water outlet of the tube-shaped electrolyte groove enters vertical current constructed wetland, while the activated sludge of biofilter bottom of pond is to aeration Persistently flow back in pond;The matrix of the artificial swamp bottom-up boulder bed for being followed successively by particle diameter 50-100mm, particle diameter 15-30mm Being planted without mud coarse sands layer, in the artificial swamp for haydite layer, the gravel layer of particle diameter 30-50mm and particle diameter 0.2-5mm is equipped with power again Flower;
6)Enter in ecological pond, the ecological pond to plant through the water after artificial wetland treatment and be equipped with water lily, eel grass and mullet grass, through life Chinese effluent after the treatment of the state pool is to natural water.
The present invention crosses facultative lagoon, artificial swamp, the group technology of ecological pond and combines traditional electrolysis process treatment rural area Sanitary sewage, not only high treating effect, secondary pollution are small, and overcome the shortcoming of traditional treatment method high cost, its investment, Safeguard and operating cost is low, be especially suitable for the relatively small rural area of the density of population, operating cost is low.
Traditional electrolysis is generally time-consuming more long, and the present invention processes the effect of sewage to ensure electrolysis, using tube-shaped electrolyte Groove, quick electrolysis treatment is carried out to sewage, and the water after treatment is entered into artificial swamp to carry out ecological optimal treatment.
Facultative lagoon is a kind of most widely used stabilization pond in the present invention, and three regions are there are in facultative lagoon:1)Top layer Aerobic zone, aerobic bacteria and algae symbiosis, the characteristics of with aerobic ponds;2)Bottom anaerobic zone, the solid accumulated in this region is miscellaneous Matter is fully decomposed by anaerobic bacteria;3)The facultative area in middle part, i.e. transition region between aerobic zone and anaerobic zone, existing can play two kinds of works Amphimicrobe, and by amphimicrobe decomposing organic matter.
In general, water plant is divided into emergent aquactic plant, floatingleaved plant, swim four kinds of (floating) plant and submerged plant etc. Type.The emergent aquactic plants such as preferred Lythrum salicaria of emergent aquactic plant etc. in the present invention, the preferred lotus of water plant planted in ecological pond, gold The submerged plants such as fish algae, and the floatingleaved plant such as water lily, can so carry out deep purifying, tail water treatment heel row up to standard to tail water Put to natural water, and graceful landscape can be built.
The further improvement of above-mentioned technical proposal is:The biofilter is supplied by being arranged on multiple aeration heads of bottom Oxygen.
The further improvement of above-mentioned technical proposal is:Step 1)In, it is advanced before domestic sewage in rural areas introduces grille well Enter to adjust sedimentation basin.Domestic sewage in rural areas through introducing regulation sedimentation basin processed with regulation, and sewage is well mixed, and makes it Water and water quality all keep stabilization, and the operating condition of a stabilization and optimization is provided for follow-up water process.
