Problems solved by technology

The system is often placed in an outdoor open environment, and the water load is not easy to control; the seasonal climate in the northern region causes large differences in rainfall throughout the year, and the common sudden infiltration system cannot maintain relatively stable soil moisture, and the operating efficiency is low
[0005] After investigation, rural domestic sewage treatment has long faced the problems of low operating funds and low water volume, and it is not suitable to adopt centralized treatment
However, the traditional decentralized ecological treatment process (such as soil infiltration) still has the problems of low operation efficiency and difficult operation supervision

Embodiment 1

[0030] Such as figure 1 As shown, the non-powered drainage and moisture retention soil infiltration device is an uncovered rectangular box (or called a pool) with an inner cavity of 5m in length, 3m in width and 3m in height. There are overflow inclined pipes, water diversion ropes and fillers arranged in the device, and drainage conduits are vertically arranged on the outer wall of the box. An overflow port is provided on the drainage conduit, and a dust-proof exhaust cover is provided on the top.

[0031] Such as figure 2 As shown, 9 drainage conduits are vertically arranged on the side walls of the two opposite sides of the box, and each drainage conduit in the middle is provided with an overflow port; the overflow port is designed as a round hole with a diameter of 50mm; the overflow The vertical and horizontal center distances of the outlets are both 0.5m, and they are arranged in two layers along the horizontal direction. The overflow ports on the nine drainage condui...

Embodiment 2

[0040] Such as Figure 7 As shown, the non-powered drainage and moisture retention soil infiltration device is a square box without a cover (or called a pool) with an internal cavity of 3m in length, 3m in width and 2.5m in height. There are overflow inclined pipes, water diversion ropes and fillers arranged in the device, and drainage conduits are vertically arranged on the outer wall of the box. An overflow port is provided on the drain conduit, and a dust-proof exhaust cover is provided on the top.

[0041] Such as Figure 8 As shown, five drainage conduits are vertically arranged on the side walls of the two opposite sides of the box, and an overflow port is provided in the middle of each drainage conduit; the overflow port is designed as a round hole with a diameter of 50 mm; The vertical and horizontal center distances of the outlets are both 0.5m, arranged in two layers along the horizontal direction, and the overflow ports on the five drainage conduits are arranged a...

Abstract

The invention provides a soil percolation sewage treatment device with unpowered flood drainage and moisture retention functions. The soil percolation sewage treatment device can drain and collect redundant water through an inclined pipe during rain and flood; and in drought, water is supplied without power by utilizing the self-absorption property of the water-absorbing material, so that low-cost adjustment of soil humidity and efficient operation of the soil infiltration system are realized.

Description

technical field [0001] The invention belongs to the technical field of sewage carbon-neutral land treatment, and in particular relates to a soil infiltration sewage treatment device with the function of non-powered drainage and moisture retention. This technology mainly treats organic pollutants through soil and plant roots on the surface. There is no need for power energy consumption during the treatment process, and carbon emissions are zero; and the growth of plants absorbs carbon dioxide, which produces carbon sinks and realizes carbon-neutral treatment of rural domestic sewage. , in line with policy trends, and has broad application prospects. Background technique [0002] Soil infiltration system is a type of sewage land treatment technology. The system distributes sewage into a soil layer with a certain structure, a certain depth from the ground, and good permeability. Through capillary infiltration and soil infiltration, The sewage is diffused to the surroundings, a...
