Further, sewage disposal microbial bacteria has been added in described aeration zone; Plant floating plant in described settling region, vegetal cover is in the water surface of settling region; Pasture and water are planted, stocked carp in described biopurification district; Flowers are planted, water-bed laying pebbles in described Landscape Region.
Further, the water inlet of described aeration zone is provided with simple and easy grid.
Further, described system is the treatment tank of the downstream watershed being located at village.
A kind for the treatment of method for rural sewage, comprises the following steps:
1, treatment tank is dug in the downstream watershed setting in village, described treatment tank comprise be communicated with successively aeration zone, settling region, biopurification district and Landscape Region, described aeration zone is provided with water-in, described Landscape Region is provided with water outlet, and sanitary sewage is entered from water-in and discharged from water outlet by aeration zone, settling region, biopurification district and Landscape Region successively;
2, establish a simple and easy grid in the water inlet of aeration zone, tackle larger pollutent, add efficient sewage disposal microbial bacteria, coordinate abundant aeration, water body is fully contacted with microorganism, degraded and the organic pollutant that transforms in sewage also destroy foul odors;
3, in described settling region, floating plant is planted, root system of plant cuts down nitrogen, phosphorus in water by the mode absorbing nutrition, and make vegetal cover in the water surface of settling region, in water body, certain anaerobic environment is created in the activity of anerobe, decompose Organic substance in water further;
4, in described biopurification district, plant pasture and water, stocked carp, by pasture and water, the absorption of the materials such as nitrate is purified water further;
5, plant flowers in described Landscape Region, water-bed laying pebbles, after Landscape Region water is full, overflow is to downstream river course.
Further, in described step 5, after Landscape Region water is full, water body is introduced farmland, irrigates.
The present invention has following advantage:
1, the present invention does not need a large amount of civil engineering, digs pit on the spot, make full use of the land resources that rural area is fallen into disuse in each natural village or production team's downstream watershed;
2, only adopt physics and biological process in sewage treatment process, as filtration, aeration, precipitation, interpolation microbial bacteria, plantation waterplant etc., secondary pollution can not be produced;
3, add the processing efficiency of efficient microbial bacteria enhanced system to aeration zone, eliminate the foul smell produced in sewage itself and treating processes simultaneously, improve Air quality;
4, plant waterplant, the effect purified water can be played, system view can be improved again;
5, whole system floor space is little, and equipment is few, and maintenance management is simple, reduced investment, can solve the unordered emission problem of domestic sewage in rural areas with minimum cost.
Accompanying drawing explanation
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of rural domestic sewage treatment system of the present invention.
Embodiment
A kind of rural domestic sewage treatment system of most preferred embodiment of the present invention, can in the water catchment area, downstream in each village, select the region that a physical features is low, dig cutter treatment tank on the spot, and pond is divided into multiple functional zone, adopt aeration to carry out pre-treatment in conjunction with special microorganism in front end area, process water outlet after the measures such as precipitation, ecological purification, qualified discharge.
Each functional area comprise be communicated with successively aeration zone, settling region, biopurification district and Landscape Region, described aeration zone is provided with water-in, described Landscape Region is provided with water outlet, and sanitary sewage is entered from water-in and discharged from water outlet by aeration zone, settling region, biopurification district and Landscape Region successively.
Aeration zone: be provided with simple and easy grid in the water inlet of aeration zone, tackles larger pollutent.Sewage enters aeration zone, by adding efficient sewage disposal microbial bacteria, coordinates abundant aeration, water body is fully contacted with microorganism, effectively degrades and transforms the organic pollutant in sewage.
Settling region: the sewage through Air Exposure enters settling region, the microbial strains that front end adds can eliminate water body foul smell, plants floating plant in settling region, and root system of plant cuts down nitrogen, phosphorus in water by the mode absorbing nutrition.Vegetal cover, in the water surface of settling region, in water body, certain anaerobic environment is created in the activity of anerobe, decomposes Organic substance in water further, also makes water body have certain sight simultaneously.
Biopurification district: this district plantation pasture and water, stocked carp.Sewage through settling region process enters biopurification district, by pasture and water, the absorption of the materials such as nitrate can be purified water further, pasture and water increase content of oxygen dissolved in water by photosynthesis, are also simultaneously fish foods, carry out biodegradable simultaneously for fish create good living environment.Water quality after the process of biopurification district can reach effluent quality requirement substantially.
Landscape Region: the water of process flows into Landscape Region, plant decontamination in Landscape Region, anti-pollution characteristic is good, the flowers that ornamental value is high, improve water transparency by the growth of flowers.Water-bed laying pebbles, coordinates flowering marsh plants to improve view.After Landscape Region water is full, can overflow to downstream river course, also can be back to farmland etc.
Table 1 Shanxi rural domestic sewage treatment result
As shown in table 1, Sewage treatment systems of the present invention and method is utilized to carry out sanitary sewage disposal in rural area, Shanxi, system continuous and steady operation 9 months, the average day process water yield 330 tons/day, the average 273mg/L of influent COD, the average 17.6mg/L of ammonia nitrogen, after treatment, Landscape Region water outlet COD≤43mg/L, ammonia nitrogen≤3.7mg/L, be better than GB18918-2002 " urban wastewater treatment firm pollutant emission standard " one-level emission standard A.
In sum, tool of the present invention has the following advantages:
1, the present invention does not need a large amount of civil engineering, digs pit on the spot, make full use of the land resources that rural area is fallen into disuse in each natural village or production team's downstream watershed;
2, only adopt physics and biological process in sewage treatment process, as filtration, aeration, precipitation, interpolation microbial bacteria, plantation waterplant etc., secondary pollution can not be produced;
3, add the processing efficiency of efficient microbial bacteria enhanced system to aeration zone, eliminate the foul smell produced in sewage itself and treating processes simultaneously, improve Air quality;
4, plant waterplant, the effect purified water can be played, system view can be improved again;
5, whole system floor space is little, and equipment is few, and maintenance management is simple, reduced investment, can solve the unordered emission problem of domestic sewage in rural areas with minimum cost.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
