Problems solved by technology

The traditional rapid infiltration land treatment system has the following disadvantages in water distribution with tanks: it is close to the root system of plants, which affects the rooting of plants and is not conducive to plant growth; overflow water distribution, impurities in sewage are deposited at the bottom of the distribution tank, which is not conducive to the removal of large particles. Long-term accumulation is likely to cause blockage of water distribution pipes and low sewage treatment effect

Embodiment 1

[0018] Such as figure 1 , 2 As shown, the anti-clogging drip irrigation and water distribution type soil rapid infiltration system is composed of a pool body 1, plants 6 and a water distribution system. First build the pool body 1, the pool body 1 is a concrete body, the aspect ratio is 1.5:1.0, and the height is 75cm. Fill sandy loam in the interior, meanwhile, in order to prevent clogging, sand column 7 is set inside the pond body 1, is piled up by river sand, high 35cm, cylinder diameter 25cm. Plants 6 are planted above the pool body 1, and a soft drip irrigation pipe 4 is arranged on the soil surface to connect with the water inlet pipe 2. The drip irrigation pipe 4 has a diameter of 4 cm and is arranged laterally on the pool body 1 . The drip irrigation pipe 4 is inverted, that is, the drip irrigation hole 5 is downward, the aperture is 0.5 cm, and the distance between the centers of the two holes is 36 cm, so as to prevent the deposition of particulate matter in the w...

Embodiment 2

[0021] Anti-clogging drip irrigation and water distribution type soil rapid infiltration system, the aspect ratio of the pool body is 1.4:1.0, and the height is 80cm. To ensure smooth operation in winter, the drip irrigation pipe 4 is covered with a rubber film.

[0022] All the other are the same as in Example 1.

Embodiment 3

[0024] Anti-clogging drip irrigation and water distribution type soil rapid infiltration system, the aspect ratio of the pool body is 1.6:1.0, the height is 70cm, and the slope of the pool bottom is 4%. The drip irrigation pipe 4 is buried 1.5cm below the soil layer.

[0025] All the other are the same as in Example 1.

Abstract

The invention discloses an anti-clogging drip irrigation and water distribution type soil rapid infiltration system and an operation method thereof. The upper part of one end of the pool body, the drain pipe is set at the lower part of the opposite end of the water inlet pipe, and the water inlet pipe is connected with the drip irrigation pipe; the drip irrigation pipe is inverted, and the drip irrigation pipe is soft; the sand column is set under the drip irrigation pipe, and gravel is piled at the outlet to prevent blockage. Plants are planted in the pond body. The system has wide application range, simple operation and low construction cost. The drip irrigation is inverted to avoid the precipitation of particulate pollutants in the water distribution pipes during the water distribution process, so that the wastewater can be fully treated. At the same time, dripping water can effectively prevent soil compaction and is beneficial to plant growth. The sand column can effectively prevent the blockage of the soil during the operation of the system.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, in particular to an anti-clogging drip irrigation and water distribution type soil rapid infiltration system and an operating method thereof. Background technique [0002] Soil rapid infiltration uses ecological principles and environmental engineering technology to realize the regeneration and recycling of sewage, so as to realize the purpose of reclaimed water reuse. Its operation mode is that the sewage is dosed to the soil surface with good infiltration performance in a controlled manner. During the downward infiltration process, the sewage is absorbed by plant roots, soil filtration, and biological oxidation, nitrification and reduction. The organic matter, nitrogen, phosphorus and other substances in the sewage are transformed and utilized, so as to achieve the purpose of sewage purification. The traditional rapid infiltration land treatment system has the following disadv...
