Abstract

The invention relates to a three-dimensional percolation self-purification system for a rainwater self-purification returning seepage well and belongs to environment-friendly equipment. A horizontal water-purifying device and a longitudinal water-purifying device are successively arranged in a well pipe from top to bottom; a space is arranged between the horizontal water-purifying device and the longitudinal water-purifying device; the longitudinal water-purifying device is composed of gravel stratum, coarse sand, fine sand, coarse sand, gravel stratum or ceramsite bedding layers which are successively put in from bottom to top; the horizontal water-purifying device comprises a rebar drum, an upper cover plate, a sealing base plate, a PVC pipe with a through hole or a steel pipe and ceramsite gravel beds; the grain sizes of the ceramsite gravel beds are gradually reduced from inside to outside; each ceramsite gravel bed is 10-30cm thick; and the porosity of the pipe wall of the PVC pipe or steel pipe is 13-25%. The three-dimensional percolation self-purification system for the rainwater self-purification returning seepage well has the advantages of novel, reasonable and simple structure, excellent use property, low cost and no groundwater pollution.

Description

technical field [0001] The invention belongs to environmental protection equipment, and mainly relates to a three-dimensional percolation self-purification system for a re-infiltration well used for natural purification of rainwater. Background technique [0002] Sponge city construction is an important part of my country's ecological civilization construction. How to increase the infiltration of surface water while not polluting the original groundwater has been paid attention to. Existing gravel piles and underground infiltration wells are the main equipment currently used to increase infiltration below surface water. However, the former has the disadvantages of small caliber, small infiltration capacity, small storage capacity, and unobvious drainage effect; the latter has the potential crisis of poor water purification effect and groundwater pollution. Contents of the invention [0003] The invention of the present invention aims at the problems existing in the above-...
