A comprehensive simulation test system for circulating pipe network water quality

Abstract

The invention discloses a circulating pipe network water quality integrative simulation test system. The system comprises a water supply subsystem and an independent circulating pipe network subsystem, wherein the water supply subsystem comprises a water supply water tank provided with a water inlet, a water outlet and a chemical filling hole; the independent circulating pipe network subsystem isa 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 virtue of pipelines; the loop isconnected with a first pipeline branch for realizing closed circulation which can be switched to quasi closed circulation, a water replenishing system for replenishing water for the loop, an emptyingbranch 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 circulating pipe network. Background technique [0002] The water supply network is an important part of the urban water supply system, and its function is to transport the water that meets the national drinking water quality standard after being purified by the water plant to the user terminal. The water quality indicators of most water plants in my country can meet or exceed the national drinking water quality standards, but when they are delivered to users through the pipe network, they often fail to meet the standards and even endanger the health of users. The data show that the water quality of the water from the water plant shows a trend of obvious decline from the factory to the user, mainly because the content of iron, manganese, chromaticity, turbidity, an...

Problems solved by technology

The storage tank is not only the test raw water deployment tank but also has the function of exhausting. However, because the circulating water samples are in contact with the air in a large area every time they flow through the storage tank, the quality of the circulating water will be affected; and the raw water tank participates in the pipe network circulation test. , there is a certain difference between the water flow conditions and the actual pipe network, resulting in a large deviation between the simulation effect and the real pipe network

Moreover, the pipeline circulation design of the entire circulation pipe network test system is very simple, and the circulation distance is short, so there are technical defects such as simulation distortion, few controllable parameters, narrow water quality research scope, and difficulty in studying working conditions and internal habitats. Substantial water quality comprehensive simulation test system for circulating pipe network

In addition, the water quality simulation test system of the open circulation pipe network in the prior art cannot pressurize and control the full pipe flow in the circulation pipe, and cannot simulate the pressurized operating environment of the real water supply main pipe network
