Embodiment 1

[0032] A method for identifying the wrong connection of a reclaimed water pipe network, comprising the following steps:

[0033] (1) Determine the pipeline connection nodes that need to be judged whether misconnection occurs in the reclaimed water pipeline network;

[0034] (2) Determine the type, dosing frequency and dosing dose of the colored tracer to ensure that the color of the tracer added in the upstream water body of the previous connection node is displayed downstream of the connection node, and before reaching the next connection node has disappeared;

[0035] (3) According to the coloring tracer type, dosing frequency and dosage determined in (2), add the coloring tracer upstream of the connection node, and observe the color of the regenerated water downstream of the connection node. If the water body in the downstream pipeline If it is colorless, it is judged that the downstream pipeline may be misconnected. If it is colored, it is judged that the downstream pipel...

Embodiment 2

[0048] This embodiment provides a reclaimed water pipe network misconnection identification system constructed by using the reclaimed water pipe network misconnection identification method in Embodiment 1, which includes a tracer automatic dosing unit 2 located upstream of the connection node 16 of the reclaimed water pipe network and a tracer located at the The online monitoring unit 3 downstream of the connection node, the tracer automatic dosing unit and the online monitoring unit are all controlled by the central controller 4; the online monitoring unit 3 includes a monitoring camera 31 and a display control module 36 connected to it, and the monitoring camera is installed in the regeneration unit. Inside the water pipe, the display control module is located outside the regenerated water pipe; or, the online monitoring unit 3 includes an automatic sampler 34 installed on the regenerated water pipe, a monitoring camera for monitoring the color of the water body in the automat...

Abstract

The invention discloses a recycled water pipe network misconnection identification method. The method comprises the following steps: (1) determining that whether a misconnected pipeline connection node occurs in the recycled water pipe network needs to judge; (2) determining the type and addition dosage of the coloring tracer, guaranteeing that the color of the tracer added in the previous connection node upstream water body can be displayed at the downstream of the connecting node and has disappeared before reaching the next connecting node; and (3) adding the coloring tracer in the upstreamwater body of the connecting node according to the determined coloring tracer type and addition dosage, and observing the water body color of the downstream of the connecting node, if the downstream water body is in a colorless state, judging that a downstream pipeline is possible in misconnection; if the downstream water body is in a developing state, judging that the downstream pipeline is freefrom misconnection. Whether the misconnection occurs is judged by directly judging the water body color in the downstream pipeline; and the entire method is simple and easy to operate.

Description

technical field [0001] The invention relates to the technical field of reclaimed water treatment, in particular to a method for identifying the wrong connection of a reclaimed water pipe network. Background technique [0002] Sewage recycling is one of the effective ways to solve the problem of water shortage and water environment pollution in my country. With the development of sewage recycling and treatment technology, recycled water has been widely used in industrial, ecological, urban and residential miscellaneous purposes, such as urban greening, toilet flushing, street cleaning, vehicle flushing, building construction, fire protection, etc. The scale and application scope are constantly expanding. Reclaimed water after advanced treatment is almost indistinguishable from drinking water in terms of appearance and smell. Reclaimed water safety accidents such as misconnection of pipe network, accidental drinking, accidental exposure, etc. are difficult to be detected and ...
