Embodiment 3

[0068] Taking the water supply process of a reclaimed water plant as an example, the water quality parameters of the deployment water are shown in Table 1.

[0069] Table 1

[0070]

[0071] The implementation of the test is to simulate the circulating water supply process: deploy the test water of the above water quality parameters in the water distribution tank 110, open the two butterfly valves 240 at the bottom of the water pipeline 210, the drain valve 111 at the bottom of the water storage and buffer tank 330, and the water intake valve and pipeline inside The exhaust valve 220 at the top of the center turns on the supplementary water pump 310, so that the deployment test water in the water distribution tank 110 is pumped into the power module 300 and the water transmission and distribution pipe network simulation module 200 through the supplementary water pump 310, and the test water is first injected into the water storage buffer tank 330. At the same time, the drai...

Abstract

The invention provides a water quality detection system of a water transmission and distribution pipe network, which includes: a water quality modulation module, which is used to deploy test water for different water quality parameters; a water distribution pipe network simulation module, which simulates the water supply pipes of the water supply pipe network, including water pipes and water pipes The water intake valve, butterfly valve, exhaust valve and detection port on the water pipe are fully enclosed and symmetrically distributed in a double serpentine shape; the power module is used to control the water flow velocity and water flow pressure of the water transmission and distribution pipe network simulation module; the control and metering module , including water quality parameter data acquisition equipment, which is connected with the detection port to detect the water quality parameters of the water in the water pipeline; the control unit, according to the water quality parameter data monitored by the water quality parameter data acquisition equipment, controls the water quality deployment module modulation and factory water or pipe network The test water with similar water quality characteristics is transported and distributed in the middle, and the power module is used to control the test water to circulate in the water pipeline according to the set pressure and flow rate, and samples are taken regularly for testing.

Description

technical field [0001] The invention relates to the field of water supply pipe network simulation, and more specifically relates to a pilot test platform and a test method for a water transmission and distribution pipe network. Background technique [0002] The water supply network is an important link in the urban water supply system, and the condition of the water supply network has a direct impact on the water quality of end users. In most urban water supply enterprises in our country, the work of improving water quality is mainly used in the purification process of water purification plants, and the water quality pollution caused by water supply pipe network is often ignored. Facts have shown that no matter how advanced the water treatment technology and process are, and how high the quality of the water leaves the factory, if secondary pollution occurs during the transportation process, users will still not be able to obtain satisfactory water quality, and it may even p...
