Example Embodiment

[0039] Example 1:

[0040] Such as figure 1 Shown as a preferred embodiment of the present invention, the artificial rapid land infiltration treatment system can be installed on the bank of a river water area, and it includes an inlet pump 1, a regulating tank 2, a flow meter 3, a percolation tank 4, and a collecting tank 5. ; Wherein the inlet 11 of the water inlet pump is connected to the river waters through a pipe, and the outlet 12 of the water inlet pump is connected to the water inlet 21 of the regulating tank through a pipe;

[0041] The adjustment pool adopts brick structure, above ground type, dimensions: length 4m, width 3m, depth 2m, effective volume is 24m 3 It has a water inlet 21 at the top and a water outlet 22 at the bottom; the adjustment tank mainly uses the height difference to make the inlet water to realize the self-flowing water supply. At the same time, it also plays the role of removing some sedimentable substances and preventing the blockage of the seepage ...

Example Embodiment

[0056] Example 3:

[0057] Application of the artificial rapid land infiltration treatment system described in Example 1, wherein natural river sand, zeolite and volcanic rock with a volume ratio of 6:1:1 are used as fillers in the infiltration tank 4. The particle diameters of the zeolite and volcanic rock are both 4- 6mm, the total thickness of the filler is 1m.

[0058] The device was used to treat polluted river water in an experimental section of the Beijing area. Microbial culture was carried out in advance by natural filming in river water, and biological culture and domestication were carried out by a culture method of 24h flooded and dried for 24h. The natural culture and domestication time required for river water was about 60 days. After this stage, the river sewage starts to be purified. First, the river sewage is pumped by the feed pump 1 into the regulating tank 2 and stays for 2h. The pretreated sewage in the regulating tank 2 is distributed through the water distri...

Abstract

The invention relates to a rapid manual land infiltration treatment system and a method for purifying river water by applying the same. The treatment system consists of a water inlet pump, a regulating tank, a flow meter, an infiltration tank, a water collecting tank, a water distribution pipe entering the infiltration tank, and a water collecting pipe flowing out of the infiltration tank. Natural sand and at least one of zeolite and lava are used as a filling of the infiltration tank. When in operation, the infiltration tank is biologically domesticated and cultured by means of natural biofilm culturing in advance, is alternatively water-flooded for 12 to 72 hours, and are dried for 12 to 72 hours in 20 to 80 days in total of domestication; river sewage enters the regulating tank after being pumped by the water inlet pump, and are settled for 0.5 to 5 hours in the regulating tank; the settled sewage is distributed by the water distribution pipe and freely flows into the infiltration tank; after the settled sewage is water-flooded for 12 to 72 hours and dried for 12 to 72 hours, the infiltration solution is collected by the water collecting pipe and is then discharged into a river.

Description

technical field [0001] The invention relates to a river sewage purification treatment technology, in particular to a system and a method for removing organic matter and ammonia nitrogen in river sewage by using a land infiltration method, and belongs to the technical field of sewage land treatment. Background technique [0002] Since the 1970s, due to the challenges of population, resources and environment, land treatment technology has brought new opportunities, and sewage land treatment has developed into one of the important sewage treatment methods that can replace secondary treatment or even advanced treatment. Sewage land treatment systems can be divided into six categories, namely slow infiltration treatment system (SR), rapid infiltration treatment system (RI), overland flow treatment system (OF), sewage wetland treatment system (WL), underground infiltration land treatment system (UG) and artificial soil rapid infiltration treatment system (ARI). The artificial rap...
