The upper and lower soil filler accounts for respectively 1/4 of device total depth, and middle level accounts for 1/2 of device total depth;
Its operation method is:
Need sewage to be processed by the water inlet pipe access to plant, under action of gravity, the sewage purified 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, 25～35cm place that the degree of depth of water inlet pipe setting is the upper layer of soil filler.
Described device, wherein, water inlet pipe connects a tank.
Described device, wherein, the degree of depth 200cm place that the degree of depth of rising pipe setting is the 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 of this device plantation landscape type 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, that installs is upper, middle level is mainly organic matter degradation, the process of denitrogenation is: Anammox reaction and nitrifying process, device lower floor, usually organic content is extremely low, traditional view is thought needs supplementary carbon source could improve the removal efficiency of nitrogen, but this device is under the condition of COD<30mg/L, can realize that organic secondary decomposes, refractory organic gradates as easily biodegradable organics, further can be used as carbon source is utilized by denitrifying bacterium, effectively improve nitric efficiency, simultaneously because power consumption is low, operational management is simple, can be applicable to municipal wastewater, centralized and dispersant type domestic wastewater processing in rural area etc.
