Comprehensive water quality simulation test system for quasi-closed circulation pipe network

Abstract

The invention discloses a comprehensive water quality simulation test system for a quasi-closed circulation pipe network. The comprehensive water quality simulation test system comprises a water supply subsystem and an independent circulation pipe network subsystem, wherein the water supply subsystem comprises a water supply tank with a water inlet, a water outlet and a medicament injection opening; the independent circulation pipe network subsystem is a loop comprising a main circulation pump, an electromagnetic flow meter and a high-level water supplementation and exhaust tank which are connected with one another in series through pipelines; the loop is connected with a water supplementation system for supplementing water to the loop, an emptying branch for emptying the water in the loop and a water quality monitoring system; and the pipelines of the independent circulation pipe network subsystem are connected with a medicament injection system. By using mutual coordination of all parts, the comprehensive water quality simulation test system for the quasi-closed circulation pipe network has the advantages of high simulation degree and higher similarity of an actual municipal water supply pipe network system.

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 quasi-closed circulation pipe network water quality comprehensive simulation test 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 iron, manganese, chroma, turbi...

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.
