Abstract
The utility model discloses a wetland ecological treatment device for municipal domestic sewage, which is characterized by mainly consisting of an adjusting tank, an anaerobic tank, an aerobic tank, a settling tank and a wetland tank. Wetland filtering materials are placed in the wetland tank, a collecting gutter is disposed in the wetland tank, and wetland plants are planted in the wetland tank. Sewage is treated by a wetland ecological treatment system. The novel wetland ecological treatment device has the advantages of high buffer capacity, good treatment effect, simple process, economical investment, low operation cost and the like, is quite suitable for treating sewage of medium and small towns, and is convenient for application and popularization.
Description
Technical field
The utility model relates to a kind of town domestic sewage Wetland ecological treatment unit.
Background technology
A large amount of pollution substances increases the weight of the pollution of receiving water body in the present town domestic sewage, causes water quality to worsen, and particularly contains a large amount of nitrogen, phosphorus in the sewage, can make body eutrophication, and this problem has caused people's common concern.Town sewage is meant the sewage that area, cities and towns resident forms in life and production process.Town domestic sewage is meant lavatory sewage effluent in the resident living process, bathing, wash clothes and kitchen waste water etc., gives birth to sewage and has a large capacity and a wide range.Water environment situation will face a very severe problem, and irrigation water is seriously polluted, and groundwater mining is seriously polluted, and surface water is continuous degradating trend, loses its original ecological environment function gradually.Wetlands ecosystems be by manual work build and the control operation with the similar ground of swampland; Sewage, mud there be batching on the artificial wetland of building of control; Sewage and mud are along in the certain orientation process of flowing; Mainly utilize physics, chemistry, the biological triple synergies of soil, artificial dielectric, plant, mikrobe, a kind of technology that sewage, mud are handled.Its mechanism of action comprises that absorption, delay, filtration, redox, deposition, microbiological degradation, conversion, plant are covered, the effect of residue accumulated, water transpiration and nutrition absorption and all kinds of animals.Wetlands ecosystems have very complicated purification mechanism to the processing of waste water; After stable, filling surface has adsorbed the large number of biological film that many mikrobes form, and root system of plant is distributed in the wetland surface; Rely on physics, chemistry, biological synergy to accomplish the scavenging process of sewage; Strengthened the soil removability of the natural wetland ecosystem, characteristics such as so need a kind of Wetlands ecosystems of utilizing to dispose of sewage, have that buffer capacity is big, treatment effect good, technology is simple, reduced investment, working cost are low; In being fit to very much, the WWT of samll cities and towns, be convenient to the novel town domestic sewage Wetland ecological treatment unit of application.
The utility model content
The purpose of the utility model is to provide a kind of Wetlands ecosystems of utilizing to dispose of sewage; Have that buffer capacity is big, treatment effect good, technology is simple, characteristics such as reduced investment, working cost are low; In being fit to very much, the WWT of samll cities and towns, be convenient to the novel town domestic sewage Wetland ecological treatment unit of application.
The purpose of the utility model realizes through following technical proposals: a kind of town domestic sewage Wetland ecological treatment unit; Mainly form by equalizing tank, anaerobic pond, Aerobic Pond, settling tank and wetland pond; Place the wetland filtrate in the said wetland pond; Wetland is provided with collecting gutter in the pond, the wetland pond wetland plant of having planted.
Biologic packing material is all installed in said anaerobic pond and Aerobic Pond inside.
Said Aerobic Pond bottom is equipped with the underwater jet aeration machine.
In sum; The utlity model has following advantage: 1) a kind of town domestic sewage Wetland ecological treatment unit, Wetlands ecosystems have very complicated purification mechanism to the processing of waste water, stable after; Filling surface has adsorbed the large number of biological film that many mikrobes form; Root system of plant is distributed in the wetland surface, relies on physics, chemistry, biological synergy to accomplish the scavenging process of sewage, has strengthened the soil removability of the natural wetland ecosystem; 2) can mainly rely on physics settlement action removal in the wet land system by settled suspended substance in the sewage.Because the wetland current are extremely slow, water is shallow, adds the barrier effect of plant stem, and suspended substance can be removed in several meters of water-ins effectively; 3) artificial swamp has stronger degradation capability to organism; Insoluble organism is through deposition, the filteration of wetland in the sewage; Can be trapped soon and utilized by mikrobe; Soluble organic in the sewage then can be through the removal that is decomposed of the biomembranous absorption of root system of plant, absorption and biological metabolism degradation process, therefore wetland bed to organic removal effect be physics hold back deposition and the biological absorption coefficient result that degrades.Main oxygen source conducts to the excess of oxygen in root district from water surface reoxygenation and plant in the reaction process.

Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is done further to specify, but the embodiment of the utility model is not limited only to this.
Embodiment: extremely shown in Figure 2 like Fig. 1; The utility model mainly is made up of equalizing tank 2, anaerobic pond 4, Aerobic Pond 5, settling tank 6 and wetland pond 7; Place wetland filtrate 16 in the said wetland pond 7, be provided with collecting gutter 17 in the wetland pond 7, wetland pond 7 wetland plant 10 of having planted.
Said anaerobic pond 4 is all installed biologic packing material 12 with Aerobic Pond 5 inside.
Said Aerobic Pond 5 bottoms are equipped with underwater jet aeration machine 14.
The principle of work of the utility model: sewage gets into equalizing tank 2 from grille well 1; Through lift pump 11 sewage is extracted into anaerobic pond 4, in anaerobic pond 4, sewage is decomposed, further in Aerobic Pond 5, decompose through mikrobe; At settling tank 6 post precipitations, get in the wetland pond 7.Wetlands ecosystems be by manual work build and the control operation with the similar ground of swampland; Sewage, mud there be batching on the artificial wetland of building of control; Sewage and mud are along in the certain orientation process of flowing; Mainly utilize physics, chemistry, the biological triple synergies of soil, artificial dielectric, plant, mikrobe, a kind of technology that sewage, mud are handled.Its mechanism of action comprises that absorption, delay, filtration, redox, deposition, microbiological degradation, conversion, plant are covered, the effect of residue accumulated, water transpiration and nutrition absorption and all kinds of plants.Generally, to COD, BOD
5, the processing efficiency of SS all can reach 70 %～90 %, and treatment effect is superior.
