Problems solved by technology

Among them, the land treatment system, such as fast infiltration, slow infiltration, surface overflow and artificial wetland system, usually has a good treatment effect on domestic sewage, but these systems have certain limitations, such as being affected by the surrounding environmental conditions and Disadvantages such as great influence of terrain, damage to the surface landscape, large footprint, and odor; although the existing underground infiltration system can make up for the shortcomings of the above sewage land treatment technology, it also has uneven water distribution, easy blockage, and low load. , Instable operation due to cold weather and other disadvantages

Embodiment 1

[0017] see figure 1 with figure 2 , A dispersed sewage underground infiltration ecological treatment system, including water distribution well 1, water inlet pipe 2, primary distribution tank 3, distribution tank pipes 4 and 5, secondary distribution tanks 6 and 7, water distribution pipe 8, dispersion pipe 9 , Water collection pipe 10, water collection well 11, observation well 12, pool wall 13, anti-seepage layer 14, and surface plants 15. In this embodiment, there are two underground infiltration areas, each of which covers an area of ​​300 meters 2 , The upper surface of the underground infiltration area is covered with herbaceous plants or shrubs 15, the surrounding pool walls 13 are compacted with clay, and the inner pipes in the underground infiltration area are filled with artificial substrate, which is 80% northeast meadow brown soil and 20% cinder (quality percentage). A water distribution system is provided between every two underground infiltration zones, includin...

Embodiment 2

[0020] see figure 1 with figure 2 , A dispersed sewage underground infiltration ecological treatment system, including water distribution well 1, water inlet pipe 2, primary distribution tank 3, distribution tank pipes 4 and 5, secondary distribution tanks 6 and 7, water distribution pipe 8, dispersion pipe 9 , Water collection pipe 10, water collection well 11, observation well 12, pool wall 13, anti-seepage layer 14, and surface plants 15. In this embodiment, there are two underground infiltration areas, each of which covers an area of ​​300 meters 2 The upper surface of the underground infiltration area is covered with herbaceous plants or shrubs 15, the surrounding pool walls 13 are compacted with clay, and the inner pipes in the underground infiltration area are filled with artificial substrates.

Abstract

The invention relates to a scattered sewage subsurface infiltration ecological processing system which comprises a plurality of subsurface infiltration regions, wherein an artificial substrate is filled around pipelines inside the subsurface infiltration regions; a water distribution system is arranged between every two subsurface infiltration regions, and comprises a water distribution well, a primary distribution tank and two secondary distribution tanks; water collection pipes are distributed on both sides of each subsurface infiltration region; one end of each water collection pipe penetrates through the tank wall of the subsurface infiltration region and enters the subsurface infiltration region, and the other end is connected with a water collection well; and a plurality of observation wells are arranged in each subsurface infiltration region. On one hand, the invention provides an ecological subsurface infiltration sewage processing system for scattered regions, such as sanatoria, holiday villages, villa areas, suburb apartment type villages and the like, and can meet the environmental protection requirements for scattered sewage processing and recycling; and on the other hand, the system has the advantages of uniform water distribution, low blocking tendency, high load and the like, and can still stably operate in cold seasons.

Description

Technical field [0001] The invention relates to a sewage land treatment technology for in-situ collection and in-situ treatment of dispersed sewage, and in particular to a sewage land treatment technology used in sanatoriums, resorts, villa areas, suburban apartment-type villages and towns, which are difficult to collect and process through municipal pipe networks The domestic sewage underground infiltration treatment system. Background technique [0002] my country is one of the countries with severe water shortage in the world. The increasingly severe water pollution situation has further exacerbated the contradiction of water shortage. In order to achieve the goal of comprehensive treatment of regional pollution, it is necessary not only to solve the problem of sewage treatment up to the standard discharge, but also to realize comprehensive reuse of sewage resources in areas where conditions permit. [0003] At present, most domestic urban domestic sewage uses a centralized tre...
