Embodiment
As Fig. 1, Fig. 2, the present invention includes the pond body and be pretreatment unit 1, kapillary moisture type waste disposal plant 2 and reuse pool 3 three parts that pre-buried pvc pipe is communicated with between underground type skeleton construction, pond body, it is characterized in that pretreatment unit comprises grating tank 4, anaerobe pond 5, settling tank 6 and the water collecting basin 7 that is communicated with successively by pvc pipe; Kapillary moisture type waste disposal plant 2 comprises cell body 8 and cell body 8 top water inlet pipes 9 and filter bed of essence 10 around the rising pipe, and is followed successively by sand and clay seam 11, pebble bed 12, and the corresponding rectangular cloth grids 13 of cell body 8 sizes (as Fig. 3), active filtering layer 14, metalling 15, clay seam 16 and surface vegetation 17 from cell body 8 bottoms to top layer.Wherein filter bed of essence 10 is mixed with 3: 1 by cinder and wood chip.Above-mentioned settling tank 6 filling plastics tubings 18, model D35, thickness of pipe 0.5mm.
The mechanism of action of above-mentioned pretreatment unit 1 comprises effects such as mechanical retention, acidication, physics sedimentation.Floating matter in the sewage mainly is to be held back removal by the grizzly bar of grid in grating tank 4; The acidication effect by anaerobion in anaerobe pond 5 of larger molecular organics in the sewage is converted into the small organic molecule that can be absorbed by microorganism; Suspended substance in the sewage separates with sewage by the physics sedimentation in settling tank 6 with mud.The part pollutent is removed in pretreatment unit in the sewage, and water quality is purified.
The mechanism of action of above-mentioned kapillary moisture type waste disposal plant 2 comprises that the filtration of soil is held back, the effects such as picked-up of physics and chemisorption, decomposition, bio-oxidation and microorganism.Be evenly distributed on the active filtering layer 14 via water inlet pipe 9 and by rectangular cloth grid 13 through pretreated sewage, active filtering layer 14 suspends being in the sewage and the organic substance of dissolved state is retained down, form one deck film of microorganism abrim on the surface of soil particle, organism in the absorption sewage, and utilize airborne oxygen, under the effect of aerobic bacteria, the organism in the sewage is changed into inorganics, as CO
2, NH
4 +, nitrate and phosphoric acid salt etc.
The active filtering layer 14 of above-mentioned peculiar set-up by sand and clay, cinder, wood chip, empty metal tin by 10: 8: 2: 1 mixed forms, empty metal tin is a right cylinder, diameter 60～80mm, height 120～150mm, active filtering layer 14 thickness are generally 500～1000mm by the decision of water inlet Pollutant levels.Active filtering layer 14 organic content are abundant, the crumb structure prosperity, and infiltration efficient height, capillary action is strong, and loading capacity is big, and permeability is good; Simultaneously, be rich in the necessary energy of microorganism and nutritive substance,, therefore have higher biological activity for soil microorganisms provides good existence developing environment.
The thickness of above-mentioned pebble bed 12 is in 200～300mm scope, and the cobble yardstick of laying is Φ 20～80mm, and its effect is the active filtering layer 14 of support.
Above-mentioned rectangular cloth grid 13 is tubular body arranged insidies that some apertures 19 are arranged at parallel or staggered connection in the rectangular pipe, top, its caliber D=50～75mm.
Above-mentioned aperture 19 is holes downward 45 ° along both sides, and the transverse pitch of aperture 19 is 30～50mm, and the aperture is 3～6mm.
Metalling 15 (thickness 100～the 200mm of above-mentioned water distribution pipe network 13 tops, the also available cobble of rubble replaces) and the combination of the clay seam 16 of top, sewage is risen along kapillary, by physics detention, a series of effects such as absorption absorption, microbiological degradation and plant absorbing of clay seam, remove the organism in the sewage.Wherein microbic activity has a very important role to the removal of organic pollutant, and being decomposed under action of microorganisms by the organic pollutant of detention and absorption changes into inorganics.
The absorption of 17 pairs of nutritive elements of surface vegetation at top is one of important channel of sewage purification.Nitrogen in the sewage, phosphorus etc. are absorbed and used by root system of plant as the necessary for plant growth nutrient, are moved out of system during mowing, reach the purpose of denitrogenation dephosphorizing, and the removal amount that can make nutritive element that often cuts the grass on a lawn reaches maximum.
The cell body 8 of whole kapillary moisture type waste disposal plant is the plastic pvc plate, or the reinforced concrete cast-in-situ plate is made.Also can lay double-deck waterproofing membrane in the cell body 8, can prevent from that sewage from permeating the ground to cause secondary pollution.Above-mentioned cell body 8 is directly to use the displaced cell body of multilayer flashing film.
Consider to reduce cost, the also available plastic pvc plate of the cell body of above-mentioned pretreatment unit 1, or the inner reinforced concrete cast-in-situ plate that lays double-deck waterproofing membrane makes, or directly use the displaced cell body of multilayer flashing film.
The filter bed of essence 10 of kapillary moisture type waste disposal plant 2 outlets, further the pollutent in the planar water makes water outlet limpid.
Non-volatile solids material in the sewage usually can stop up the space between grogs, thereby influences the speed of sewage permeation, hinders entering of air, at this moment because the animal in the soil navigates between grogs as worm and nematode etc., can make loosing soil.Sewage is purified through biotic synergism in physics, chemical action and the soil ecosystem of above mechanical retention, anaerobic hydrolysis-acidification, physics sedimentation and soil, enters reuse pool 3 backs by rising pipe and stores reuse.
