A groundwater recharge system and its operation method

Abstract

The invention discloses a groundwater replenishment system and an operation method thereof, comprising a water collecting tank, an infiltration tank and an infiltration port. The water collecting tank is arranged on the ground by stacking, and a water inlet pipe is arranged inside the water collecting tank. There is a filter screen at the connection, and a filter sedimentation tank is arranged at the other end of the water inlet pipe. The water inlet pipe is connected with the interior of the filter sedimentation tank. The bottom of the filter sedimentation tank is provided with a permeation tank on the side away from the collection tank. They are communicated through a water inlet pipe provided at the ground end of the filter sedimentation tank. The invention realizes the collection of rainwater by means of a water collection tank provided, and collects the rainwater and passes through the water inlet pipe. When the water level in the collection tank reaches the design water level, the excess water will pass through the water inlet pipe and flow into the interior of the filter sedimentation tank. , Through the filter screen provided, the larger floating objects in the sump, such as leaves, etc., can be filtered out, so as to prevent the floating objects from entering the filtering sedimentation tank with the water flow, thereby causing blockage.

Description

technical field [0001] The invention relates to the technical field of groundwater replenishment, in particular to a groundwater replenishment system and an operation method thereof. Background technique [0002] Groundwater recharge is the use of artificial measures to inject water from surface water or other water sources into the ground to supplement groundwater, so as to increase groundwater resources, alleviate the continuous decline of groundwater levels, purify water quality, curb seawater intrusion and other ecological and environmental benefits, also known as Artificial groundwater recharge and groundwater recharge. Aquifer recharge technology (MAR, Managed AquiferRecharge) is a technical method for purposely storing water in suitable aquifers, and adopts a series of management measures to ensure that human health and environmental safety are not damaged, and contribute to the improvement of the ecological environment , solve especially the seasonal water shortage ...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the traditional groundwater recharge systems only add water or other water sources directly into the osmosis device through the osmosis device, and the groundwater is replenished through the osmosis device without deep filtration, which cannot guarantee the water quality. Pollution to underground water sources, and most of the drive's infiltration devices do not have the function of collecting rainwater and filtering it
