Fig. 1 is structural representation of the present utility model.
Drawing illustrates: 1, Primary plateaus drowned flow artificial wet land, 2, homogeneous gravel, 3, reed, 4, perforated pipe, 5, pump well, 6, secondary table artificial wetland, 7, planting soil, 8, Canna generalis Bailey, 9, swag, 10, downgrade reed, 11, artificial ecological floating island, 12, Scirpus tabernaemontani.
Embodiment
Describe particular content of the present utility model by reference to the accompanying drawings in detail.A kind of unpowered ecological wastewater treatment system, sanitary sewage enters cloth tank by collecting after urban households' septic tank, then Primary plateaus drowned flow artificial wet land 1 is evenly entered by the perforation tracery wall of cloth tank side, this Primary plateaus drowned flow artificial wet land 1 adopts particle diameter to be 50-70mm, thickness is that the homogeneous gravel 2 of 1.2m is as filler, cultivated plant selects reed 3, the bottom of homogeneous gravel 2 is provided with water gathering system, this water gathering system adopts perforated pipe 4, the water outlet of perforated pipe 4 communicates with pump well 5, the side relative with pump well 5 opening is provided with secondary table artificial wetland 6, this secondary table artificial wetland 6 adopts planting soil 7 as filler, the height of filler is lower than the minimum overflow height of pump well 5 opening, cultivated plant selects waterplant Canna generalis Bailey 8, the bottom of planting soil 7 is provided with water gathering system, this water gathering system adopts perforated pipe 4, the water outlet of perforated pipe 4 communicates with swag 9, the side slope of swag 9 depth of water 0.2-1.0m is planted and downgrades reed 10, depth of water 1.5-2.5m place arranges artificial ecological floating island 11, this artificial floating island 11 to be planted waterplant Scirpus tabernaemontani 12.
Native system carries out rational deployment by artificial swamp and local swag and river, utilizes the gravity flow effect of sewage, can process sanitary sewage without the need to power.Sanitary sewage enters artificial swamp cloth tank by collecting after each family oriented manure pit, cloth tank evenly enters one-level artificial swamp by perforation tracery wall, Performance of Constructed Wetlands Substrates adopts homogeneous macrobead gravel, can ensure that effective sewage treatment load can prevent again artificial swamp from blocking and occur overflow phenomena.Water gathering system adopts perforated pipe, and process water outlet is in pump well, and the end seal sliding connection adjustable water outlet pipe of perforated pipe, this adjustable water outlet pipe adjusts its freeboard according to its pitch angle and then realizes according to season and the temperature adjustment one-level artificial swamp depth of water.The removal of SS is mainly by physical sedimentation, filteration, and the removal of BOD is mainly by microorganism adsorption and metabolism, and meta-bolites is harmless stable material, and BOD concentration remaining in water after process therefore can be made very low.The principle that in sewage, COD removes is substantially identical with BOD.
The mechanism of action of the present utility model is: on the removal of pollutent with affect the precipitable solid of physical sedimentation gravity settling in wetland and remove, filter, being made by the interception of attractive interaction effect and root system of plant between particle can sedimentation and can being removed by stopping by flocculate solids; Chemistry microbial metabolism: utilize the bed mud suspended and the metabolism parasitizing the bacterium on plant that suspended substance, colloid, soluble solids are resolved into inorganics; Nitrogen is removed by biological nitration-denitrification; Part trace element is oxidized by microorganism, plant utilization and is removed through stopping or combine.Natural death: bacterium and virus are in and are not suitable for nature being caused in environment to decay and death, plant metabolism utilizes plant to remove organic absorption, secretions from plant roots has a considerable amount of nitrogen of deactivation plant absorption and phosphorus can be absorbed by plants and remove to intestinal bacteria and pathogenic agent, the raw plant in perennial marsh, annual harvesting once, can shift out artificial wet land system by after nitrogen, phosphorus absorption, synthesis point.
The utility model utilizes local swag, river to be simply transformed into the ecosystem having and purify waste water and beautify the environment.Shoaling water plantation cattail and dwarfing reed, artificial ecological floating island is arranged in ballow.On the one hand, show and utilize the very large root system of plant of surface-area in water, form dense net, suspended substances a large amount of in adsorbed water body, and form microbial film on root system of plant surface gradually, in film, microorganism engulfs becomes inorganics with the pollutent in metabolic water, becomes the nutritive substance of plant, is converted into the composition of vegetable cell by photosynthesis, promote that it grows, reduce water Middle nutrition salt finally by gathering in chinampa plant and catching fishes and shrimps; On the other hand, chinampa suppresses the photosynthesis of algae by keeping the sun off, reduce phytoplankton growth amount, phytoplankton subsiding is impelled by contact precipitation effect, effectively prevent " wawter bloom " to occur, improve the transparency of water body, its effect is more obvious relative to the former, plant simultaneously on chinampa can perch for birds, and bottom root system of plant forms fish and aquatic insect habitat.Artificial ecological floating island purifies water, embellishing surface view, provide hydrobiont perch space and carry out the several functions such as Environmental education.
Design variable: the comprehensive treating process load of artificial swamp is 0.4m 3/ m 2d;
Original swag and river hydraulic detention time > 30d.
Artificial swamp of the present utility model is the advanced water purifying technique by artificial construction and controlling run, sewage, mud there is the dosing of control in artificial swamp, sewage is in the process flowed in a certain direction, mainly utilize soil, artificial dielectric, plant, the physics of microorganism, chemistry, biological triple synergy, to a kind of technology that sewage processes.Its mechanism of action comprises absorption, delay, filtration, redox, precipitation, microbial decomposition, conversion, plant are covered, the effect of residue accumulated, water transpiration and nutrition absorption and all kinds of plant.Sewage is had to the effect of deep purifying, realize the target of vacuum in draft tube.
The processing power of Sewage treatment systems of the present utility model is high, and effluent quality can reach the one-level B standard in GB18918 " urban wastewater treatment firm pollutant emission standard ", and water outlet directly can be disposed to physical environment.Except some central drainages of rural development good except some economic conditions and Sewage treatment systems, the construction of the sewage disposal that the economic condition in most of rural area and schooling support are not conventional and operation.And the Sewage treatment systems of this project compensate for these shortcomings, at present along with the enhancing of everybody environmental consciousness, low cost, less energy-consumption, have wide market outlook without the need to the Sewage treatment systems of complex management.
More than show and describe ultimate principle of the present utility model; principal character and advantage; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall into claimed scope of the present utility model.
