Embodiment 1

[0040] Such as figure 1 Shown is a preferred embodiment of the present invention, the artificial rapid land infiltration treatment system can be arranged on the banks of river waters, and it includes a water inlet pump 1, a regulating tank 2, a flow meter 3, a percolating tank 4 and a sump 5 Wherein the inlet 11 of the water inlet pump is connected with the river waters through a pipeline, and the outlet 12 of the water inlet pump is connected with the water inlet 21 of the regulating tank through a pipeline;

[0041] The adjustment pool adopts a brick structure, above ground, with dimensions: length 4m, width 3m, depth 2m, effective volume 24m 3 , the top has a water inlet 21, and the bottom has a water outlet 22; the function of the adjustment tank is mainly to use the height difference to make the water supply water in a self-flowing manner, and it also removes part of the sedimentable matter and prevents the clogging of the seepage tank.

[0042] The water outlet 22 of th...

Embodiment 3

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

[0058] The device was used to treat polluted river water in an experimental river section in Beijing. The microbial culture was carried out in advance by the method of natural membrane hanging in the river water, and the biological cultivation and domestication was carried out by the cultivation method of flooding for 24 hours and drying for 24 hours. The time required for the natural cultivation and domestication of the river water is about 60 days. After this stage, the river sewage starts to be purified. First, the river sewage is pumped by the water inlet pump 1 into the regulating tank 2 and settled for 2 hours. The pretreated se...

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...
