Embodiment Construction

[0009] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. A rainwater natural reinfiltration and purification horizontal device, in which an earth pit 3 with a depth H of 1-1.5 meters is set on the land, and a PVC plate basket or a steel plate basket 1 is configured in the earth pit 3 that can be extracted and moved up and down. A ceramsite layer 2 is installed in the PVC plate basket or steel basket 1, and the ceramsite in the ceramsite layer 2 is spherical ceramsite with micropores, and the spherical ceramsite in the ceramsite layer 2 adopts a particle size of The size gradually decreases from top to bottom, and then gradually increases from small to small. The particle size of the smallest spherical ceramsite in the ceramsite layer 2 is 0.1mm, and the drainage port 4 is set in the PVC basket or steel basket 1. on the bottom side.

[0010] Since the overall change trend of ceramsite particle size is from lar...

Abstract

The invention relates to a horizontal device for rainwater natural infiltration and purification and belongs to an environment-friendly purifying device. A 1-1.5m deep pit is arranged on the ground; a PVC plate basket or steel plate basket which can be moved by up and down extracting is arranged in the pit; a ceramsite layer is added into the PVC plate basket or steel plate basket; spherical ceramsite with micro-pore is arranged as the ceramsite in the ceramsite layer; the spherical ceramsite in the ceramsite layer has a configuration structure of grain size gradually reducing and then gradually increasing in turn from top to bottom; a water outlet is formed on a bottom part of the PVC plate basket or steel plate basket. The device has the advantages of novel, reasonable and simple structure, reliable operation, excellent permeability, high purifying quality, strong regulation and storage capacity, corrosion resistance, low cost, convenience in maintaining and cleaning and long service life.

Description

technical field [0001] The invention belongs to environmental protection purification equipment, and mainly relates to a horizontal device for rainwater natural back seepage purification. Background technique [0002] Sponge city construction is an important part of my country's ecological civilization construction, and one of the important measures is to increase the infiltration of surface water. However, in areas with poor permeability in shallow strata and deep buried aquifers, the infiltration of surface water is very slow, the amount of infiltration is small, and the infiltration water cannot be effectively used. How to increase the amount of infiltration of surface water in such areas, and at the same time collect as much surface water as possible for production and life is a technical problem that should be solved. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and to design and pr...
