A comprehensive water quality simulation test system for dual water source water supply circulation pipe network

Abstract

The invention discloses a double water source water supply circulating pipe network water quality integrative simulation test system. The system comprises a water supply subsystem and independent circulating pipe network subsystems, wherein the water supply subsystem comprises a first water supply water tank and a second water supply water tank; the first water supply water tank is provided with a water inlet, a water outlet and a chemical filling hole; the second water supply water tank is communicated with the first water supply water tank by a pipeline with a second valve and is provided with a water inlet, a water outlet and a chemical filling hole; each independent circulating pipe network subsystem is a loop comprising a main circulating pump, an electromagnetic flowmeter and a high-level water replenishing and exhausting water tank which are connected in series by a pipeline; the loop is connected with a first pipeline branch for realizing closed circulation, a water replenishing system for replenishing water for the loop, an emptying branch for discharging the water in the loop and a water quality monitoring system; and meanwhile, chemical filling systems are also connected on the pipeline of the independent circulating pipe network subsystem. All the components of the system cooperate with each other and the system has the following advantages: the system has high simulation degree and is closer to the practical municipal water supply pipe network systems.

Description

technical field [0001] The invention relates to the technical field of a test simulation system for a drinking water supply pipe network, in particular to a water quality comprehensive simulation test system for a dual water source water supply circulation pipe network. Background technique [0002] The water supply pipe network is an important part of the urban water supply system. Its function is to deliver water that meets the national drinking water quality standards after being purified by the water plant to the user terminal. The water quality indicators of most waterworks in my country can meet or exceed the national drinking water quality standards, but when it is delivered to users through the pipe network, it often fails to meet the standards and even endangers the health of users. According to the data, the water quality of the water plant shows a trend of decreasing obviously from the factory to the user, mainly manifested in the increase of the content of iron, ...

Problems solved by technology

The reservoir is not only a test raw water deployment pool but also has the function of exhaust gas. However, the built-up open circulation pipe network test system is generally small in scale, the cycle design is very simple, and the cycle loop is short. In essence, it cannot be regarded as a high simulation. Comprehensive simulation test system for water quality of circulating pipe network

Specifically, there are mainly poor simulations of water flow conditions in the design (every time the circulating water sample flows through the reservoir, it is in contact with the air in a large area, which will affect the quality of the circulating water; and the raw water pool participates in the pipe network cycle test, and the water flow conditions are different from the actual pipe network. There are certain differences), insufficient control of conditions (such as unable to pressurize the full pipe flow in the circulation pipeline, and unable to simulate the pressurized operating environment of the real main water supply pipe network), single simulation conditions (such as unable to realize the nature of multiple water sources Switching, dual water source mixed water supply, sudden change of external source polluting water quality, secondary chlorination of pipe network and other complex working conditions), large simulation distortion and many other technical problems
