Constructed wetland adopting monitoring electrodes embedded in enclosure walls for in-situ blockage monitoring

Abstract

The invention discloses a constructed wetland adopting monitoring electrodes embedded in enclosure walls for in-situ blockage monitoring. The constructed wetland comprises a water distribution area, awater collection area, a main packing area, aquatic plants, monitoring electrode belts, strip-shaped copper electrodes, connecting wires and long-side enclosure walls, wherein the main packing area is surrounded by the water distribution area, the water collection area and the long-side enclosure walls, the water distribution area and the water collection area are opposite, and the two long-sideenclosure walls are opposite; the two parallel monitoring electrode strips are embedded horizontally in each long-side enclosure wall, and totally the four monitoring electrode strips are embedded; the distance from the monitoring electrode strips to the top and bottom of the wetland is 20 cm; strip-shaped copper electrodes with spacing of 20-100 cm are mounted on each monitoring electrode strip and are connected by the wires, and the aquatic plants are planted at the upper part of the main packing area. The constructed wetland has the advantages that the blank of accurate blockage monitoringof constructed wetlands is filled in, and technical guarantee is provided for treatment, operation and maintenance of the constructed wetlands of various specifications as well as continuous and efficient operation of the constructed wetlands.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to an in-situ monitoring artificial wetland for blockage in which monitoring electrodes are embedded in walls. Background technique [0002] Constructed wetland sewage treatment technology is a new ecological engineering technology for sewage treatment that emerged in the 1970s. It has the advantages of good flexibility, low investment, low energy consumption, strong decontamination ability, convenient management, and no secondary pollution. Applications are increasingly common. However, in recent years, problems such as clogging frequently occur in constructed wetlands during operation, the purification performance decreases, and the service life is shortened. For example, among the 355 subsurface flow constructed wetlands in the United States and the United Kingdom, nearly half of them were clogged within five years of use, and the hydraulic conductivity of t...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing constructed wetland cannot accurately monitor the clogged area, resulting in no effective technical basis for clogged treatment and maintenance, to provide a constructed wetland that is easy to construct and accurately monitors clogged, and can realize accurate monitoring of the clogged area of ​​the constructed wetland , to provide technical support for the continuous and efficient operation of constructed wetlands
