A water distribution device and water distribution method for artificial wetland

Abstract

The invention discloses an artificial wetland weed suppression and water distribution device. A weed suppression and water distribution plate is provided with a plurality of water distribution units and ventilation units of the same structure. The water distribution units are connected with the ventilation units. Each water distribution unit is provided with a water distribution head. Each ventilation unit is provided with a ventilation head. The water distribution heads are arranged downwards. The ventilation heads are arranged upwards. The joints of the water distribution units and the ventilation units form shading and weed suppression components. A water distribution perforated pipe comprises a water distribution hole for guiding water into the weed suppression and water distribution plate. According to the artificial wetland weed suppression and water distribution device and method, the weed suppression components are composed of the water distribution units and the ventilation units; due to water cross flow and the multi-point structure of the water distribution device, water oxygenation and uniform water distribution are achieved, soil has the good ventilation, weed growth is prevented, and deadwood and garbage are isolated; accordingly, the wetland treatment efficiency is improved, and operation and management are easy and feasible; in addition, the weed suppression and water distribution method can reduce the number of water distribution perforated pipes and the number of perforated holes.

Description

technical field [0001] The invention relates to the technical field of environmental protection and landscaping, in particular to a water distribution device and a water distribution method for an artificial wetland. Background technique [0002] The existing artificial wetland treatment process occupies a large area, and the water distribution is basically completed by perforated pipes, such as figure 1 , figure 2 As shown, this construction method will be limited by factors such as pipeline cost, perforation diameter, quantity, and water pressure. Water distribution can only be concentrated on the strip water distribution line around the outlet hole of the water distribution pipe, resulting in poor water distribution uniformity and no water distribution. During the oxygenation process, the utilization rate of the process filler is low. In addition, the wetland plants are planted at intervals, and the open space between the plants is easier to grow weeds. At the same time...

Problems solved by technology

[0003] The purpose of the present invention is to provide a device for suppressing weeds and distributing water in constructed wetlands to solve the problem that the artificial wetland treatment process in the prior art occupies a large area, and the water distribution is basically completed by perforated pipes with dry branch structures. This construction method will be affected by the pipeline cost , perforation diameter, quantity, water pressure and other factors, the water distribution can only be concentrated on the strip water distribution line around the outlet hole of the water distribution pipe, resulting in poor water distribution uniformity, no oxygenation process for water distribution, and low utilization rate of process fillers. low technical defect
