Embodiment 1

[0136] This example will be as figure 1 The system shown is applied to a constructed wetland with long side length a=80m and short side length b=30m for routine real-time monitoring. The system mainly includes a mobile leak detection device 1, a data terminal 2 and a server 3; each mobile leak detection device 1 is connected to the data terminal 2 through a cable 4, and the data terminal 2 is used to receive various detection data and upload various detection data. to server 3. like figure 2 As shown, the constructed wetland 5 is mainly composed of a wetland plant 5-1, a wetland filler 5-2 and an impermeable membrane 5-3, and the impermeable membrane 5-3 is used to separate the wetland filler 5-2 from the lower soil 6. The mobile leak detection device 1 of this system is set in the wetland packing 5-2, and the set depth is 0.3m above the top of the impermeable membrane 5-3. The mobile leak detection device 1 includes a water pressure sensor 1-1 for collecting water pressur...

Embodiment 2

[0145] In this embodiment, the method of the present invention is applied to a constructed wetland with a long side length a=80m and a short side length b=30m for real-time routine monitoring, accurate source tracing and in-situ repair.

[0146] The real-time routine monitoring part of the leakage of the constructed wetland in this embodiment is the same as that in Embodiment 1. The difference between this embodiment and Embodiment 1 is that the upper tolerance limit of P is taken as α=30%, and the upper tolerance limit of C is β=30%. Although P=27.63%≤α, C=36.41%>β, it is determined that the constructed wetland has potential leakage, it is necessary to follow the image 3 The steps shown are for further traceability determination.

Abstract

The invention discloses a real-time monitoring, accurate tracing and in-situ repairing system and method for artificial wetland leakage, and the system comprises a mobile leakage detection device, a data terminal and a server, and a water pressure sensor and a conductivity sensor of the mobile leakage detection device carry out the real-time monitoring of the leakage condition of the artificial wetland. If the maximum relative deviation P of the water pressure is smaller than the standard value alpha and the maximum relative deviation C of the conductivity is smaller than the standard value beta, it is judged that leakage does not occur in the constructed wetland, and otherwise, the leakage detection device needs to be moved to accurately trace the leakage condition; when the total leakage area At is smaller than the standard value At1, the constructed wetland continues to operate, and otherwise, in-situ remediation needs to be conducted on the constructed wetland until the measured value At is lower than the standard value At1; the system solves the problems of real-time monitoring, accurate traceability and in-situ remediation of the constructed wetland, and has the advantages of quick response, high sensitivity, convenience in operation, low investment, environmental friendliness and the like.

Description

technical field [0001] The invention belongs to the technical fields of energy conservation and environmental protection, water treatment and water environment restoration, and particularly relates to a system and method for real-time monitoring, accurate traceability and in-situ restoration of leakage of artificial wetlands. Background technique [0002] Due to the advantages of low investment and construction cost, low operating cost, low operating technology, and the ability to combine landscape construction, constructed wetlands have been treated in a wider range of domestic wastewater in recent years, including urban domestic sewage, rural domestic sewage, farmland return water, and aquaculture wastewater. Wait. However, due to the complex composition of artificial wet inflow water, once leakage occurs, the content of ammonia, nitrogen, phosphorus, COD and other organic matters and heavy metals in the surrounding rivers and groundwater will increase sharply, which will ...
