Operational mode of the present utility model and principle of work are as follows:
Municipal effluent or sanitary sewage from blow-off line at first pass through means pre-treatment such as oil removal precipitation, intermittently enter diafiltration Sewage treatment systems under the artificial soil of high hydraulic load then.
In the diafiltration Sewage treatment systems, sewage mainly enters aproll-ventilation metalling A by aproll-ventilation pipe network A under the artificial soil of high hydraulic load, and part enters aproll-ventilation metalling B by aproll-ventilation pipe network B.Sewage is diafiltration downwards under action of gravity, and remainder particulate thing wherein is many by last anti-blocking layer, down anti-blocking layer interception, and different and be scattered in each soil layer and on the interface, to increase its bio-contact oxidation area, quicken the decomposition of particulate organic matter according to particle diameter.Dissolved organic matter is mainly adsorbed by the artificial soil horizon and is degraded by soil bacteria, NH
4 +Mainly by electronegative absorption such as clay mineral, phosphorus is then removed by absorption and precipitation.Because aproll-ventilation metalling A and aproll-ventilation metalling B be the upwards anti-blocking layer supply oxygen from the above and below respectively, and down the oxygen supply of anti-blocking layer is mainly from the aproll-ventilation metalling B of its top, and the pollutant load ability that therefore goes up anti-blocking layer is greater than anti-blocking layer down.The aproll pump moves 6～8 times every day, is no more than 40 minutes at every turn, and the aproll pump quit work back about 1 hour, and to underground filtration system power ventilation, aproll-ventilation pipe network and one of them pipe network of ventilation pipe network are air intake passage, and another pipe network is as air exhaust passage.Its ventilation is 6～8 times of sewage volume.It is more even that this short cycle cloth aqueous mode can make sewage distribute, and the increase artificial soil horizon falls to doing the time.Falling to doing period, the artificial soil horizon is in aerobic environment, and the residual organic matter in the soil is decomposed under the effect of aerobic bacteria, recovers the crumb structure and the perviousness of soil, and makes the NH that is adsorbed
4 +Under the effect of nitrobacteria, be oxidized to nitrate radical, the NH in the soil
4 +Adsorption potential is discharged again; The artificial soil horizon is in anaerobic environment during water distribution, helps the carrying out of denitrification.
The utility model compared with prior art, have following advantage and beneficial effect: (1) supposes that the aproll amount of the utility model technology aproll-ventilation metalling (B) is half of aproll-ventilation metalling (A), then can make the sewage portative power of subsurface wastewater infiltration system improve 50%, this will enlarge the scope of application of this technology; (2) the utility model technology increases an anti-blocking layer down, but can reach the effect that increases by 50% sewage portative power, and this will reduce the construction cost of system greatly.
A day to handle 100m
3System be example, adopting publication number is the Chinese patent of CN1927733A, the about 250m of required subsurface infiltration area
2Adopt the utility model technology, if sewage is handled the about 170m of required subsurface infiltration area equally through primary reinforcement
