Embodiment

[0043] The test of this example was carried out in a 12° slope outside the farmyard of a villager in Wangdian Village, Sanyuan County, Xianyang City, Shaanxi Province, and the test time was from January to February 2021. System structure such as figure 1 As shown, from top to bottom, there are: plant layer 1, planting soil layer 2, water distribution layer 3, first soil infiltration layer 41, second soil infiltration layer 42, supporting layer 5, infiltration system Anti-seepage walls 8 are set around and at the bottom.

[0044] The plant layer 1 is planted with holly and Chinese rose, the planting soil layer 2 is composed of 50cm thick cultivated soil; the water distribution layer 3 is 15cm thick and is composed of coarse sand with a particle size of about 4cm; In the water layer 3, the water distribution pipe 6 is composed of a DN10PVC water distribution main pipe and a DN5PVC water distribution branch pipe. The water distribution main pipe is set along the direction from t...

Abstract

The invention discloses an unpowered self-flowing type underground soil infiltration system which sequentially comprises a planting soil layer, a water distribution layer, a soil infiltration layer and a supporting layer from top to bottom, the whole soil infiltration system is inclined, and the soil infiltration layer sequentially comprises a first soil infiltration layer and a second soil infiltration layer from top to bottom. The first soil percolation layer and the second soil percolation layer are of wedge-shaped structures matched with each other, and the soil density of the first soil percolation layer is lower than that of the second soil percolation layer. A water distribution pipe is arranged in the water distribution layer, a water inlet is formed in the highest position of the water distribution layer, and a water outlet is formed in the lowest position of the supporting layer. By constructing the variable-density and variable-thickness soil percolation layer, partitions of an oxidation-reduction environment are optimized, the hydraulic retention time of sewage in the system is prolonged, the sewage treatment and purification energy efficiency of the system is improved, meanwhile, the occupied area of the system is reduced, and the integrated functions of high operation efficiency, small occupied area and no external source driving force of the system are realized.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an unpowered self-flowing underground soil infiltration system. Background technique [0002] Rural living pollution points are many and widespread, which is one of the important reasons for the severe situation of rural non-point source pollution. Especially in the construction of new countryside in my country's loess area, finding a suitable technology for rural domestic sewage treatment is one of the important problems that need to be solved urgently, and the underground soil infiltration system is one of the most suitable technologies. [0003] The underground soil infiltration treatment system is an artificially enhanced sewage ecological treatment technology. It makes full use of the physical, chemical and biological functions of the animals, microorganisms, plant roots and soil that live in the soil below the surface to purify the sewage. It belongs t...
