Embodiment 1

[0045] Example 1: Central city storage pool A

[0046] Based on the existing construction of storage pool A in the central urban area, according to figure 1 Make a transformation. One side of the interception well 2 is connected to one end of the water inlet pipe 1 of the interception well, and the other side is connected to one end of the water inlet pipe 5 of the storage tank. The storage tank inlet gate 8 on one side of the storage tank 7, the TSS online detector 6 is installed on the pipeline connected to the storage tank 5 and the storage tank, and the acoustic flowmeter 10 of the storage tank is installed on the upper part of the storage tank 7 To monitor the water level, the storage tank 7 is provided with a water inlet flowmeter 9 at the inlet gate 8 of the storage tank, and the other side of the storage tank 7 is provided with a water outlet gate 12 of the storage tank, and the storage tank 7 is located at the outlet gate 12 of the storage tank There is a water out...

Embodiment 2

[0064] Example 2: Storage pool B in central urban area

[0065] Based on the existing construction of storage pool B in the central urban area, according to figure 1 Make a transformation.

[0066] The total volume of storage pool B in the central city V 实际 =18000m 3 , the effective storage volume V 有效 =15000m 3 , V 有效 ’=13500m 3 , set the water level to -3m.

[0067] The diameter of the main water inlet pipe of the pumping station is 3500mm, and the elevation of the inner bottom of the pipe is -5.60m. The rainwater pump uses 6 submersible mixed flow pumps, and the single pump Q=3.33m 3 / s. Set up 2 submersible sewage pumps for emptying, using variable frequency pumps, and the flow rate of a single pump is 0.35 ~ 1.01m 3 / s.

[0068] Install a TSS online detector 50m away from the inlet of the water inlet. Due to the large water storage capacity and at least 3 rainwater pumps working at the same time, the flow rate must be greater than 3 m 3 / s, so the TSS online ...

Abstract

The invention belongs to the field of municipal administration, and particularly relates to a method and device for intelligent operation of a rainwater storage tank. The intelligence of the storage tank is achieved by monitoring a certain index of initial rainwater of a pipe network on line, and the water quality index TSS which can represent the initial rainwater is screened out mainly based onthe correlation coefficients of the concentrations of pollutants in the initial rainwater. The system and the device comprise a TSS online detector, an electric valve and an acoustic Doppler flow-meter. After the TSS online detector monitors the peak value change trend of the concentration of TSS in the initial rainwater, the electric valve is automatically switched on, and the real-time dynamic balance of inflowing water and the water capacity of a tank body is maintained. The system and the device can directly identify the initial rainwater with the scouring effect, automatically bring the initial rainwater into the storage tank, prevent later rainwater with low pollution load from entering the storage tank, greatly reduce the possibility of overflow pollution, and achieve the intelligence of the storage tank.

Description

technical field [0001] The invention belongs to the field of municipal administration, and in particular relates to a method and device for intelligent operation of rainwater storage tanks. Background technique [0002] Studies have shown that the initial rainwater has a high pollutant load and is the main source of non-point source pollution. The initial rainwater itself scours the ground with many residual organic pollutants, and also disturbs the black mud deposited in the pipes. If it is not managed and directly discharged into the river, it will not only cause the river to become black and smelly, and destroy its sensory effect, but also its own pollutants will destroy the growth of animals and plants in the river, seriously damaging the water environment of the river. Therefore, the initial rainwater must be managed and controlled to avoid damage to the ecological environment such as river courses. [0003] At present, although some urban rainwater pipe network syste...
