Embodiment 1

[0048] Such as Figure 1-9Among them, an intelligent diversion well that prevents the backflow of sewage interception main pipes, including a water inlet chamber 1, a sewage interception chamber 2 and a water outlet chamber 3 arranged in a foundation enclosure 6, and the sewage interception chamber 2 and water outlet chamber 3 are located in the water inlet chamber 1- On the side, a drainage pump 4 is provided between the water inlet chamber 1 and the sewage intercepting chamber 2, and an anti-backflow device 5 is provided between the water inlet chamber 1 and the water outlet chamber 3. The drainage pump 4 and the anti-backflow device 5 are used to control the sewage interception Chamber 2 and the communication between the water outlet chamber 3 and the water inlet chamber 1. Drainage pump 4 adopts QJB-W pump, which has controllable overall operation and high precision. The anti-backflow device 5 can adopt bottom opening weir gate, hydraulic rotary weir gate, hydraulic non-re...

Embodiment 2

[0064] The method of using the anti-sewage interception main pipe for backfilling the intelligent diversion well includes the following steps:

[0065] S1. In the initial state, the drainage pump 4 is closed, the anti-backflow device 5 is closed, and the water inlet chamber 1 and the sewage interception chamber 2 are kept connected;

[0066] S2. Real-time monitoring of the real-time water level hj of the water inlet chamber, the real-time water level hw of the sewage interception chamber and the real-time water level hc of the water outlet chamber, and record the data;

[0067] S3. When it is sunny, the drainage pump 4 is corresponding or closed according to the water level h2 (set maximum value), hw and hj of the water inlet chamber;

[0068] S31. If hw≤h2, keep the initial state;

[0069] S32. If hw≥h2, turn on the drain pump 4 until hj drops to the water level h1 (minimum value set) in the water inlet chamber, and turn off the drain pump 4;

[0070] S33. When a rain warni...

Abstract

The intelligent diversion well comprises a water inlet cavity, a sewage intercepting cavity and a water outlet cavity which are arranged in a foundation enclosure, the sewage intercepting cavity and the water outlet cavity are located on one side of the water inlet cavity, a drainage pump is arranged between the water inlet cavity and the sewage intercepting cavity, and a backflow prevention device is arranged between the water inlet cavity and the water outlet cavity. The drainage pump and the anti-backflow device are respectively used for controlling communication between the sewage intercepting cavity and the water inlet cavity as well as between the water outlet cavity and the water inlet cavity. The problems that a traditional flow dividing well is greatly influenced by the water level of the sewage intercepting main pipe, the water storage capacity of the sewage intercepting main pipe and the flow dividing well is limited, and normal work of the flow dividing well is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to an intelligent diversion well for preventing sewage interception main pipes from backfilling. Background technique [0002] The water level of the sewage interceptor is changing, sometimes high, sometimes low, such as when the drainage peak or rainfall is relatively high, especially in the rainy southern cities, the groundwater level is high, sometimes even because of the sealing problem of the pipeline, the long-term drainage of the sewage interceptor is caused. Running at a high water level (pipelines are full, and the liquid level of the inspection well is equal to the groundwater level) will cause the following problems: (1) The sewage in the interception main pipe will be poured into the diversion well, or even discharged into the river through the water outlet; ( 2) In order for the diversion well to have the function of sewage interception, the water level of the w...
