A water distribution system of a groundwater restoration device

Abstract

The invention discloses a water distribution system for a groundwater remediation device. The system includes a water distribution pipe, which is formed by connection of several round tubes with equal length and different pipe diameters. The pipe wall of the water distribution pipe is provided with three rows of holes, each row of holes are equidistantly arranged along a cylinder bus, and the central angle corresponding to the arc-shaped pipe walls between adjacent two rows of holes is 45degree-75degree. The small pipe diameter end of the water distribution pipe is connected to a water conduit of the groundwater remediation device, and the large pipe diameter end is a sealed end. The holes of the water distribution pipe are downward embedded between one side of a first level filler layer's upper surface and a first layer water insulation baffle, multi-layers of water insulation baffles parallel to the first level filler cross section are disposed in the first level filler layer, the length of the water insulation baffles is 70%-85% of that of the first level filler layer, the interlaced ends of the multi-layers of water insulation baffles are connected to the side wall of the first level filler layer, and the other ends are folded upward by an angle. A second level filler layer is disposed below the first level filler layer.

Description

technical field [0001] The invention belongs to the field of groundwater pollution restoration, and in particular relates to a water distribution system used in a groundwater pollution restoration device. Background technique [0002] The invention titled "A Restoration Device for Ammonia Nitrogen Contaminated Groundwater" (Application Publication No. CN 103613199 A) discloses the adsorption of media materials available for groundwater restoration devices, the absorption and utilization of plants, the nitrification and denitrification of microorganisms , to achieve efficient removal of ammonia nitrogen pollutants in groundwater. It is a new type of groundwater restoration device that optimizes the combination of wetland technology, permeable reaction wall technology and well irrigation technology. It has low cost, easy construction, small groundwater disturbance, strong flexibility, and restoration functions. Strong and adaptable features. [0003] In the process of groundw...

AI Technical Summary

Problems solved by technology

The existing water distribution system of the device adopts the water distribution method with uniform openings around the single pipe wall, which is prone to uneven water distribution, and the polluted groundwater is not easy to fully contact with the primary packing layer, thereby shortening the number of pollutants in the groundwater. The residence time in the primary packing layer, which in turn affects the effect of groundwater remediation
