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 (for example, it is impossible to pressurize the full pipe flow in the circulation pipeline, and it is impossible to simulate the pressurized operating environment of the real water supply main pipe network; the temperature of the test water in the circulation pipeline is easily affected by the temperature of the four seasons in the environment Influenced by temperature, unable to control temperature to simulate the operating temperature of the real water supply pipe network buried in the ground), the simulated working conditions are single (such as the inability to switch between multiple water sources, mixed water supply from dual water sources, sudden changes in water quality caused by external sources of pollution, pipe network two The simulation of various complex working conditions such as secondary chlorine addition), the simulation distortion is large (for example, the biggest factor affecting the residual chlorine decay of the actual pipe network is the water temperature of the pipe network, if the test system cannot control the temperature, it will be inconsistent with the actual pipe network operation results There are large errors) and many other technical problems

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 circulating pipe network with a temperature control system. 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 iro...
