Description
Technical field
The utility model belongs to technical field of sewage, especially a kind of heat preserving type domestic sewage in rural areas by using artificial wet land treating system.
Background technology
Along with the transformation of rural areas in our country expanding economy and life of farmers mode, domestic sewage in rural areas by using generation increasing year by year, its problem of environmental pollution that causes becomes increasingly conspicuous, and lacks sewage treatment facility in addition, makes the water pollution problems in rural area more serious.The water bodys such as the river of rural area most areas, lake are generally polluted, and drinking-water quality is subject to safely serious threat, directly endangers the healthy of peasant, has a strong impact on the environmental health of Rural areas, very easily causes generation and the propagation of some epidemic diseases.
Domestic sewage in rural areas by using has the characteristics different from municipal effluent, and domestic sewage in rural areas by using mainly is washing, shower and the draining of part sanitary ware, and the water yield is different because of the difference of regional economy degree.Domestic sewage in rural areas by using generally has the characteristics such as few, the contained organic concentration of discharge capacity is relatively higher, daily variation factor large (generally between 3.0～5.0), intermittently discharged.Country sewage mainly contains the feature of following four aspects: (1) people in the countryside distribute and comparatively disperse, and the general intermittently discharged of sewage and quantity discharged are less; (2) the sewage network gathering system is unsound, and wastewater treatment rate is low; (3) Pollutant levels are relatively high in the sewage, and biodegradability is strong; (4) water quality and the water yield are larger with season, round the clock variation, and daily variation factor is large.These characteristics for domestic sewage in rural areas by using, the processing of domestic sewage in rural areas by using has following requirement: (1) rural area (town) population is less, distribute wide and dispersion, sanitary sewage water quality, water yield fluctuation are large, network of drains is very unsound, therefore selected sewage treatment process answers capacity of resisting impact load strong, and individual curing nearby; (2) the villages and small towns economic force is weak, so sewage disposal should take into full account that cost is low, working cost is few, the technique of less energy-consumption or Non-energy-consumption; (3) villages and small towns lack the sewage disposal professional, and selected technique answers operational management simple, and is easy to maintenance.
At present, on rural domestic sewage treatment, biochemical process is because treatment effect is good, working cost is low, stable the forming of operating performance taken technique as the leading factor, wherein, constructed wetland waste water treatment technology is a kind of method that meets ecological viewpoint and sustained development theory, it is for the characteristics of rural area scattered settlement, with artificial swamp dispersion treatment country sewage and at each family or each village nearby individual curing be more outstanding scheme.Organism in the sanitary sewage and nitrogen and phosphorous nutrient are microorganism and waterplant nutrients in the artificial swamp, and waterplant has purified sewage in growth; The power consumption of this kind mode is few, invest little, and simple to operate, easy maintenance; Select the waterplant of economic worth, when purifying waste water, also can produce economic benefit.But, there is following problem in existing domestic sewage in rural areas by using artificial wet land treating system: (1) is because the domestic sewage in rural areas by using organic concentration is higher and have a more suspended matter, when adopting single Wastewater Treatment by Constructed Wetlands, wetland effluent water quality can not be guaranteed, particularly cause microorganism raised growth breeding in wetland owing to organic loading is higher, add wet land filler holding back and filteration suspended matter in the sewage, so operation along with wet land system, the wet land system porosity reduces, cause wet land system to stop up, sewage can not normally pass through wetland, and wet land system can not normally move.Wet land system can not be disposed of sewage after stopping up, and self is difficult to recover; Only have by changing filler and reconfiguring plant to solve, this can strengthen investment and the running cost of wetland.(2) effect of artificial swamp processing domestic sewage in rural areas by using is subjected to the impact of temperature condition larger: on the one hand, wetland plant can not normal growth under the cold condition, can't rely on wetland plant to absorb nitrogen and phosphorous nutrient in the sewage, wetland effluent nitrogen phosphorus index can not reach standard; On the other hand, microbe population is few in wet land filler and the root system of plant under the cold condition, activity is low, can not effectively remove the pollutent in the sewage.Therefore under cold condition, effect was relatively poor when artificial swamp was processed domestic sewage in rural areas by using, can't accomplish the end in view.
Summary of the invention
