Building water supply pretreatment device based on ultraviolet chlorine advanced oxidation

Abstract

The invention discloses a building water supply pretreatment device based on ultraviolet chlorine advanced oxidation. The device comprises a water supply pipe main body and a controller, the two ends of the water supply pipe main body are respectively provided with a water inlet and a water outlet, and the water supply pipe main body is respectively provided with a first electromagnetic valve and a second electromagnetic valve; the water supply pipe main body is connected with a first branch water pipe, a water inlet and a water outlet of the first branch water pipe are communicated with the water supply pipe main body positioned on two sides of the first electromagnetic valve, and the first branch water pipe is provided with a chlorine metering and dosing device for performing chlorination and disinfection on water flowing through the first branch water pipe; through cooperation of the chlorine metering and dosing device and the ultraviolet device, different disinfection treatment modes can be adopted for tail end water according to different results obtained after detection water sample analysis, the disinfection treatment is more reasonable and efficient, and the water use safety of a user is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a building water supply pretreatment device based on ultraviolet chlorine advanced oxidation. Background technique [0002] After the water comes out of the water plant, it enters the municipal pipe network for long-term and long-distance transportation, and the water quality is prone to pollution, such as the leakage of toxic substances in groundwater, sudden organic pollution, bacterial proliferation pollution, etc., which will affect the safety of drinking water for the people. Initiate a challenge, especially the old residential areas in the urban area are the hardest-hit areas. Therefore, in addition to the necessary normal prevention and control, it is necessary to do some necessary treatment of the drinking water at the end of the pipe network to ensure the water safety of the people. However, there are currently few processes suitable for treating drinking water a...

Problems solved by technology

However, there are currently few processes suitable for treating drinking water at the end of the building. This is because firstly, the treatment process must not cause secondary pollution; secondly, the treatment equipment must be simple and durable; thirdly, the treatment facilities must not affect people's daily life
