Background technology
According to the guide of Environmental Protection Agency (USEPA) and the land treatment system that published by China Standards Press, the degree of depth of sewage disposal filtration system is generally 1.0 ~ 2.0m, has not yet to see the research report of the device of the filtration system more than 2.0m.Traditional view thinks that system mainly occurs in the scope of the 30-50cm on the upper strata of device to organic removal, and the removal of ammonia nitrogen or total nitrogen is in the scope of 50-120cm.At the back segment (within the scope of 90cm-120cm) of Efficiency for Soil Aquifer Treatment, COD < 30mg/L, biodegradability is low, and denitrification limits by carbon source, and the removal ability of the total nitrogen of system declines.In order to improve the removal efficiency of total nitrogen, general Efficiency for Soil Aquifer Treatment provides carbon source for anti-nitration reaction at soil lower floor appropriate depth shunting raw waste water or throws in methyl alcohol at system back segment; Although improve the clearance of total nitrogen so to a certain extent, but result in running cost high, the problems such as management maintenance trouble.
The problems such as the nitric efficiency of Efficiency for Soil Aquifer Treatment is low for descending traditionally, and supplementary carbon source running cost is high, management maintenance trouble; A kind of dark type underground filtration system is proposed, the advantages such as hardly degraded organic substance can be utilized by denitrifying bacterium as carbon source within the system, and it is high that this waste disposal plant has nitric efficiency, and operational management is simple.
Summary of the invention
A kind of dark type underground filtration system is the object of the present invention is to provide to dispose of sewage device
Operation method.
For achieving the above object, operation method provided by the invention:
The top, one end of this device is provided with water inlet pipe, is provided with rising pipe bottom the other end of this device;
This device from top to down is filled with the soil filler of different-grain diameter, and the particle diameter of the soil filler of the upper and lower is 0.10-0.30mm, and the particle diameter of BC soil filler is 0.08-0.1mm;
The upper and lower soil filler accounts for 1/4 of device total depth respectively, and middle level accounts for 1/2 of device total depth;
Its operation method is:
Need sewage to be processed by water inlet pipe access to plant, under gravity, cleaned sewage is discharged by rising pipe.
Water inlet is intermittent water inlet, and twice water inlet interval is not less than 1 hour;
Described device, wherein, the described device degree of depth is 2-5m.
Described device, wherein, the degree of depth that water inlet pipe is arranged is 25 ~ 35cm place of upper layer of soil filler.
Described device, wherein, water inlet pipe connects a tank.
Described device, wherein, the degree of depth that rising pipe is arranged is the degree of depth 200cm place of lower soil filler.
Described device, wherein, water inlet pipe and rising pipe are the perforated pipe of PVC material.
Described device, wherein, the top layer plantation landscape type of this device or economical plant.
Its degree of depth of device that dark type underground filtration system of the present invention is disposed of sewage is in the scope of 2-5m, device upper, middle level is mainly organic matter degradation, the process of denitrogenation is: Anammox reaction and nitrifying process, device lower floor, usual organic content is extremely low, traditional view thinks the removal efficiency needing supplementary carbon source could improve nitrogen, but this device is under the condition of COD < 30mg/L, organic twice decomposition can be realized, refractory organic gradates as easily biodegradable organics, can be used as carbon source further to be utilized by denitrifying bacterium, effective raising nitric efficiency, simultaneously low owing to consuming energy, operational management is simple, can be applicable to municipal wastewater, centralized and dispersant type domestic wastewater process in rural area etc.
