The suction culvert from aerating regulation pond is provided with in strengthening ecological pool 4, advection water distributor 41, aeration tube 42, face, pond is divided into plant isolated area 45, floating plant growing area 46, pool bottom sludge bucket 44 is provided with at the bottom of pond, pool bottom sludge bucket 44 is provided with mud valve, the Main Function of this part: from the water inlet in aerating regulation pond 2 to advection water distributor 41 water distribution uniformity, establish aeration tube two near advection water distributor, play the effect of artificial oxygenation.Surface grafting floating plant and emergent (floating plant growing area 46), and two to three regions are set do not plant any plant (accounting for about 1/10 of surface-area, plant isolated area 45), ensure water-bed ecological normal.Water surface institute kind of plant mainly contains: the chrysanthemum fire hose, Herba Eichhorniae, Shi Long Bing, garden sorrel, calamus, iris.Selected plant is very high to the clearance of nitrogen phosphorus.The bed mud that the booty of plant-growth or dead generation and suspended substance sedimentation produce, can enter earthworm natural decomposition system by mud valve and carry out natural decomposition.Can be removed in this part most COD and nitrogen phosphorus, clearance can reach 85%.
As shown in Figure 2, earthworm natural decomposition pond 5 structure is from bottom to up geomembrane 51, metalling 52, soot layer 53 and dirt bed 54; And cultivation has earthworm in earthworm natural decomposition pond 5; Top, earthworm natural decomposition pond 5 is provided with water distributor 55, and bottom is provided with shore pipe 56.Earthworm natural decomposition pond 5 is provided with 3, and 3 earthworm natural decomposition ponds 5 arrange from high to low, between adopt pipeline be connected; First earthworm natural decomposition pond 5 is connected by pipeline with strengthening ecological pool 4.Geomembrane 51 has steel concrete.
First earthworm natural decomposition pond 5, is provided with in pond into water water distributor, geomembrane, different diameter rubble, coal ash, plant (Arundo donax, again power flower etc. plant corresponding plant in conjunction with local circumstances), earthworm, rising pipe, shore pipe and mud valve.This partial action, from the water outlet water distribution uniformity of strengthening ecological pool to earthworm decomposing pool surface, by the Decomposition of plants on surface and earthworm, removing the pollutent from strengthening in the water outlet of ecological pool, removing most of SS, COD and nitrogen phosphorus.
Second earthworm natural decomposition pond 5, constructs the same, but the water inlet of this part is provided with the shore pipe 56 from strengthening ecological pool 4, the mud of decomposable asymmetric choice net strengthening ecological pool 4 under the effect of earthworm.Concrete effect is with first earthworm natural decomposition pond 5.
3rd earthworm natural decomposition pond 5, its tectonism is the same, arrives this part, and water COD clearance of finally releasing can reach about 95%, and removal efficiency of nitrogen and phosphorus can reach more than 90%.
Grille well 1 is connected with aerating regulation pond 2 by waste pipe 6; Aerating regulation pond 2 is connected with the advection water distributor 41 in strengthening ecological pool 4 with pipeline by lift pump, and strengthening ecological pool 4 is connected with earthworm natural decomposition pond 5 by pipeline; Be connected by waste pipe 6 between earthworm natural decomposition pond 5; Collecting pipe 31 is connected with gas collection blower fan 32, and be connected with aerating regulation pond 2 with gas piping 7 by gas collection blower fan 32, catch pit 34 is connected with aerating regulation pond 2 by percolate pipe 35, and revolution blower fan 33 is connected with the aeration tube 42 strengthened in ecological pool 4 with aerating regulation pond 2 by pipeline.
Lattice coral well and aerating regulation pond 2 locate below ground level, and other are positioned at more than ground; Strengthening ecological pool 4 is positioned at above garbage transfer station 3, and first earthworm natural decomposition pond 5 is same high with strengthening ecological pool 4, and the position in other earthworm natural decomposition ponds 5 reduces successively.
The concrete running of this system is as follows:
Sewage enters lattice coral well 1 and filters larger rubbish and solid pollutant, then enters aerating regulation pond 2 and processes from the sanitary sewage filtered through lattice coral with from the percolate of garbage transfer station and the foul smell of garbage transfer station.Sanitary sewage and part percolate, under the effect of combined stuffing and aeration, form microbial film, under the effect of aerobic bacteria, remove most COD in sewage and ammonia nitrogen and part phosphorus.And from the foul smell of garbage transfer station, passing into microbial film place by gas collection blower fan carries out biological adsorption, carries out biological deodorizing.Aerating regulation pond is provided with sewage pump, adopts liquid automatic control, pumps into strengthening ecological pool, the Main Function of this part, from the water inlet in aerating regulation pond to advection water distributor water distribution uniformity, near water distributor, establish aeration tube two, play the effect of artificial oxygenation.Surface grafting floating plant and emergent, and two to three regions are set do not plant any plant (accounting for about 1/10 of surface-area), ensure water-bed ecological normal.Water surface institute kind of plant mainly contains: the chrysanthemum fire hose, Herba Eichhorniae, Shi Long Bing, garden sorrel, calamus, iris.Selected plant is very high to the clearance of nitrogen phosphorus.The bed mud that the booty of plant-growth or dead generation and suspended substance sedimentation produce, can enter earthworm natural decomposition system by mud valve and carry out natural decomposition.Can be removed in this part most COD and nitrogen phosphorus, clearance can reach 85%.Entered the water after the process of strengthening ecological pool from flowing to earthworm decomposing pool 1, water outlet water distribution uniformity from strengthening ecological pool is surperficial to earthworm decomposing pool, by plants on surface and the Decomposition of earthworm and the dialyzing of soil, remove from the pollutent in the water outlet of strengthening ecological pool, remove most of SS, COD and nitrogen phosphorus.The water outlet of earthworm decomposing pool 1 flows automatically to earthworm decomposing pool 2, and this pond structure is with 1, but this pond has the effect of process from strengthening ecological pool mud concurrently, the water outlet of earthworm decomposing pool 2 flows into earthworm decomposing pool 3 by pipeline, effect is with 1, and intensive treatment step by step, earthworm grading pool 3 water outlet is water of finally releasing.
Garbage transfer system, garbage transfer station 3 is for depositing rubbish and elimination percolate, and timing man-handling of materials is to destructor plant.
Garbage transfer stench processing system, mainly by the gas collection blower fan in garbage transfer station, adopts time controling, and timing automatic starts, and collects the foul smell in transhipment station, by pipeline, passes into aerating regulation Chi Shengwumochu, carry out biological adsorption.
Garbage percolation liquid treating system is mainly the process of filtrate in rubbish, and the bottom of garbage transfer station is provided with filter screen and catch pit, and the part percolate of collection enters aerating regulation pond automatically, processes together with Sewage treatment systems.
