Punch position between described deflection plate 4 is differed, it is ensured that current are not straight line in uphill process Motion, adds the residence time of sewage, while in sewage uphill process, current and the frequent impact of deflection plate 4, sewage mixing effect It is really good, it is easier to be settled down to bottom after being collided in particulate matter uphill process, not only increases the treatment effect to organic matter, The suspension content in sewage can also effectively be reduced.
Collecting methane valve 6, external corresponding gas collection cleaning system are housed at the top of described pond body on closure 2.
The described aperture position of overflow delivery port 7 is higher than deflection plate 4, and maintains the discrepancy in elevation between closure 2.
Described the first grit 10 composition of layer are grit, highly in 20-30cm, and zeolite filler 11 composition of layer are boiling Stone, highly in 70-80cm, the effect of the first grit layer 10 is, can be intercepted by the filtering crop of grit from anaerobic digestion The suspension that pond comes out, the effect of zeolite filler layer 11 is, ammonia nitrogen that can largely in absorption effluent and adsorbs small part phosphorus, Improve wet land system Microbial denitrogenation dephosphorization efficiency.
Described the first filter element 8, the bottom of the second filter element 9 are provided with the through hole being connected, through hole and add sieve Net, to keep current insertion.
The described composition of blast furnace slag packing layer 12 is blast furnace slag, and highly in 40-50cm, the composition of tire debris packing layer 13 is Tire debris, highly in 30-40cm, the composition of the second sandy gravel stratum 15 is grit, highly in 10-20cm;Blast furnace slag packing layer 12 Effect is, phosphorus that can largely in absorption effluent, improves treatment effeciency of the artificial swamp to phosphorus, tire debris packing layer 13 Effect is, can a large amount of nitrate in absorption effluent, reduce water outlet nitrate content, the effect of the second sandy gravel stratum 15 is to prevent Only tire debris are lost in.
Described discharge outlet 14 is located at the top of the second filter element 9, highly less than overflow delivery port 7, it is ensured that current exist It can be discharged under not acted on by external force from discharge outlet.
Service condition of the present utility model is, including modified form anaerobic digester and filtration system two parts, in sewage warp Heart water inlet pipe 1 enters the bottom of pond body 3 from the closure 2 at the top of modified form anaerobic digester, then slowly rises through deflection plate 4, Flowed out from the overflow delivery port 7 of the top of pond body 3, the biogas that anaerobic fermentation is produced is collected through the top collecting methane valve 6 of pond body 3, mistake Filter system is divided into two units, and first module is connected with second unit bottom, and first module filler is grit, zeolite, current From top to bottom, second unit filler is blast furnace slag, tire debris and grit in direction, water (flow) direction from bottom to up, from modified form The sewage that anaerobic digester is overflowed, by the water distribution pipe of overflow delivery port even into filtration system, the second filtering is single First water outlet uses downflow weir mode, and height of weir plate is less than the water distribution pipe of overflow delivery port, when the first filter element water level is high When the second filter element height of weir plate, the water after processing is flowed out from the discharge outlet 14 of downflow weir, and sludge is passed through through mud discharging mouth 5 Pump periodically extracts pool bottom sludge.
Case study on implementation 1, treating capacity is 10 ton days, BOD of intaking5Average value in 254mg/L, COD average values in 448mg/L, Total phosphorus is 6mg/L, and ammonia nitrogen is 51mg/L, 25 DEG C of temperature, under the conditions of hydraulic detention time 24h, water outlet BOD5Average removal rate 79.4%, COD average removal rate 86.2%, ammonia nitrogen removal frank 80%, total tp removal rate 70%.
Case study on implementation 2, treating capacity is 10 ton days, BOD of intaking5Average value in 254mg/L, COD average values in 448mg/L, Total phosphorus is 6mg/L, the micro- 51mg/L of ammonia nitrogen, 15 DEG C of temperature, under the conditions of hydraulic detention time 24h, modified form anaerobic digester water outlet BOD5Average removal rate 48.2%, COD average removal rates 42.6%, ammonia nitrogen removal frank 50%, total tp removal rate 48%.
Calculated according to water consumption 200L for each person every day, 10 tons of water consumptions equivalent to 50 people, currently without drainage pipeline networks Old every building of cell at most 2-14 families, an average family 3-4 people calculates, and sum should be 50 or so.
From the foregoing, the utility model can effectively realize the processing to cell domestic water, application of the present utility model The discharge of water pollutant can be greatly decreased, water environment pollution problem is contained from source, can also be in dirty drainage pipeline networks Residential area and rural area are used, and sanitary sewage can be effectively treated, and effectively alleviate water environment pressure, simple to operate, Easy to use, operating cost is low, is the innovation on sewage-treatment plant, with good social and economic benefit.
