Embodiment 1

[0104] A drainage system with a hydraulic down-opening weir gate and pump drainage, the drainage system includes: a diversion well, a water inlet 2 and a water outlet 3 arranged in the well body 1 of the diversion well;

[0105] The diversion well includes: a hydraulic down-opening weir gate 4, the hydraulic down-opening weir gate 4 is arranged near the water outlet 3, and is used to control the amount of water passing through the water outlet 3;

[0106] Sunny day submersible sewage pump 5 and rainy day submersible sewage pump 6, the drainpipe of described sunny day submersible sewage pump 5 and the drainpipe 8 of rainy day submersible sewage pump 6 extend to the outside of the shunt well body 3 and are connected with the sewage riser 10.

[0107] In a preferred embodiment of the present invention, the drainage system also includes a control system 9, the control system includes a monitoring device and a control unit; It is connected with the submersible sewage pump in rainy ...

Embodiment 2

[0135] This embodiment provides a drainage control method controlled by the water level method. The drainage control method is based on the drainage system described in Embodiment 1. The drainage system includes a control system, and the monitoring device in the control system includes monitoring water body fluid. In the control unit of the control system, the warning water level H2 of the diversion well, the liquid level height of the submersible sewage pump in sunny days h2 and the liquid level height of the submersible sewage pump in rainy days h3 are set. And h2<h3<H2; the method includes the following steps:

[0136] 1a) The water body enters the diversion well from the water inlet, and the liquid level height H in the diversion well body is monitored in real time through the device for monitoring the liquid level of the water body;

[0137] 2a) When h2

Embodiment 3

[0143] This embodiment also provides a drainage control method controlled by the water quality-water level method, the drainage control method is based on the drainage system described in Embodiment 1, the drainage system includes a control system, and the monitoring device in the control system includes The device for monitoring the liquid level of the water body and the device for monitoring the water quality of the water body are both installed in the well body of the diversion well. In the control unit of the control system, the warning water level H2 of the well body of the diversion well and the start-up liquid level of the submersible sewage pump in sunny days h2 are set. , the liquid level height of the submersible sewage pump in rainy days is h3, and h2<h3<H2; the standard value of pollutant concentration C1 is set; the method includes the following steps:

[0144] 1b) The water body enters the diversion well from the water inlet, and the water level height H in the di...

Abstract

The invention discloses a water draining system with a hydraulic downwards-open check gate and the pump draining function and a water draining control method. The water draining system is provided with a rainy-day submersible sewage pump, a sunny-day submersible sewage pump and the hydraulic downwards-open check gate; according to the liquid level height of water bodies in a well body of a flow dividing well or the water quality of water bodies in the well body of the flow dividing well, whether submersible sewage pumps work or not and the hydraulic downwards-open check gate is started or notcan be judged, and reasonable distribution of the water bodies is thus achieved. The water bodies with different water levels and / or water qualities can also be reasonably drained, and therefore the maximum governance effect is achieved. The water draining system is particularly suitable for the condition that a pipe extending to a sewage treatment plant is located at the high elevation and cannotbe drained in a gravity mode; as the submersible sewage pumps are arranged in the water draining system, water bodies with the poor quality in the well body of the flow dividing well are drained to the sewage treatment plant in a pump-draining mode, and during emergency flood discharging, sewage can also be drained to natural water bodies through a water outlet.

Description

technical field [0001] The invention belongs to the technical field of drainage, and in particular relates to a drainage system with a hydraulic downward opening weir gate and pump drainage and a drainage control method. Background technique [0002] At present, the drainage system of cities and buildings mainly includes diversion system, confluence system and mixed flow system, the main purpose of which is to realize the collection, transportation and treatment of water bodies. For example, a system that treats all wastewater in one way is called combined. It has only one drainage system, called the confluence system, and its drainage pipe is called the confluence pipe. The system that treats different types of wastewater in different ways is called the diversion system, which generally has two drainage systems. One can be called a rainwater system, which is used to collect rainwater and industrial wastewater with a very low pollution level that is directly discharged int...
