Description
Technical field
The invention belongs to environmental pollution treatment technologies, are used for rural domestic sewage treatment.
Background technology
Rural environment, which exists, is piled up arbitrarily rubbish, and production, sanitary sewage arbitrarily discharge phenomenon, seriously threaten rural area water body
Ecological safety.Domestic sewage in rural areas is mostly derived from life washing, kitchen food and drink, livestock culture, rubbish, excrement etc., there is that total amount is big,
It is widely distributed, complicated component, it is difficult to collect, the features such as concentration and big changes in flow rate, dispersant type domestic wastewater greatly threatens
The freshwater resources of China.
Currently, China's rural sewage treatment technology still rests on simple process stage, the rural domestic sewage treatment in China
There are many technology type, the present invention be mainly unpowered biological method sewage disposal technology, ecological method treatment technology it is integrated.
Invention content
The technology of the present invention is by unpowered treatment facility (buried slot)+oxidation pond (floating plant the area)+surface-flow of integration
The sewage disposal technology of (emergent aquactic plant area)+ecological canal is integrated.Buried experiment reaction unit is made of cast iron quality, experiment dress
It sets including pre-procesor, biological treatment device, flocculation deposition apparatus.
Description of the drawings
Fig. 1 is integration apparatus vertical view of the present invention；
Fig. 2 is the buried slot equipment plan view of bioanalysis of the present invention.
Specific implementation mode
The families peasant household 1-2 share a buried slot.The sewage that peasant household generates enters after subsoil drain enters the processing of buried slot
Full village sewage network further stops purification after collection into oxidation pond floating plant area, and water outlet enters surface-flow and handles, most
After be discharged into ecological canal.
One, the buried slot of unpowered biological method：
Equipment uses cast iron cylinder equipment for customizing, paint coat after the outer brush anti-decaying paint of equipment, interior brush ring oxygen resin resistant material；Directly
Diameter 1.6m, high 3m inside set three processing reaction subregions.
Pre-procesor：The waste water that peasant household generates directly removes water float by sewer pipe by 1 simple process
Enter buried slot after object and suspended matter.
Biological treatment device：Sewage enters biological processing unit through 2 deflector water conservancy diversion after ensuring enough residence times
-- PAN-ACF activated carbon fibers are as processing unit.It has abundant microcellular structure, pore size distribution range wide；Specific surface area
It is very big, all generally there is larger adsorption capacity in 1000m2/g or more；Its micropore is directly distributed in the surface of fiber, thus
Adsorbate diffusion path is short, the time is short, absorption and regenerated rate are fast, can be compared with being regenerated under temperate condition.By water inlet
Inoculation domestication culture, on its surface, attachment, update, form stable biomembrane, can effectively reduce the pollutant concentration in water.
PAN-ACF activated carbon fibers are 1.0 meters per Shu Changdu, arrange 20 beams altogether.
Flocculation deposition apparatus：9 configuration DN50 pipes.Sewage enters flocculation sediment unit after biological processing unit is handled, and adds
Enter flocculant water outlet after a series of physical such as cohesion, absorption, precipitation chemistry further purification and enters oxidation pond.
Two, oxidation pond (floating plant area) treatment technology
By buried sewage treatment equipment treated sewage enters oxidation pond unit, 18 days residence times are designed.Oxidation pond
To be built as unit of village.The village generates about 100 tons of sanitary sewage daily, enters through collecting pipe network and collecting after the processing of buried slot
Oxidation pond processing.1400 square metres of oxidation pond plane, oxidation pond pool bottom absolute altitude in the side of a pond to the pool by gradually deepening, plantation lotus,
1.0-1.5 meters of depth in the pool.
Three, surface-flow (emergent aquactic plant area)
Surface-flow designs 8 days residence times according to existing terrain design-build, about 3600 square metres of area, plants reed
Reed and the stem or leaf of cattail.
Four, ecological canal
Enter ecological canal after surface-flow water outlet to handle, ecological canal grass planting bank protection, 300 meters of overall length is further purified through ecological canal
After discharge.
The project implementation
Place：The Changchun High-Tech Development Zones Jing Yue village
Time：The 5-8 months in 2016
The project implementation process：
Prepare work, oxidation pond, surface-flow and ecological canal construction the 5-6 months；The 6-8 months：Breeding strain, operation debugging, treatment facility
It runs basicly stable.
Result of implementation：
The villages Lin Jia village sanitary sewage disposal water quality situation
The removal rate of water outlet COD reaches 92%, the buried slot removal rate of unpowered biological method 75%；BOD5Unpowered biological method is buried
Slot removal rate 76.9%, total system removal rate 92.3%, ammonia nitrogen removal frank 66.2%, total tp removal rate are 66.2% or so.
Effluent quality reaches when stable operation《Urban wastewater treatment firm pollutant emission standard》(GB18918-2002) level-one B standard.
