A secondary water supply intelligent supplementary chlorine disinfection system and a supplementary chlorine method

Abstract

The invention discloses an intelligent chlorine-supplementing and disinfecting system for secondary water supply and a chlorine-supplementing method. The actual condition of a water tank is comprehensively considered; on the basis of the existing sodium hypochlorite generator technology, a miniature sodium hypochlorite generator which is simple in structure, easy to maintain, automatic in operation and capable of meeting the disinfection requirement of the water tank is designed. A dilution device is small in size, convenient to install, automatic in operation and capable of diluting the disinfection stock solution produced by the sodium hypochlorite generator by more than 1000 times. Therefore, when the residual chlorine concentration of the tap water in the water tank is lower than a setvalue, a sodium hypochlorite disinfectant with the concentration allowed to be used by laws and regulations is automatically prepared and added into the water tank, and the tap water in the water tank can continuously keep enough residual chlorine concentration.

Description

technical field [0001] The invention relates to the field of secondary water supply of urban water supply pipe network systems, in particular to an intelligent supplementary chlorine disinfection system for secondary water supply and a method for supplementary chlorine. Background technique [0002] At present, most of the disinfection of urban drinking water (commonly known as tap water) in my country is disinfected with chlorine-containing preparations. After adding chlorine-containing preparations to tap water, it can maintain sufficient residual chlorine concentration in the tap water pipe network system for a long time, thereby ensuring The microorganisms in tap water are controlled within the qualified range, and residual chlorine refers to the amount of chlorine remaining in water after chlorine is added for a certain period of time when chlorine-containing preparations are used for disinfection. Commonly used chlorine-containing preparations are liquid chlorine, chlor...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the above-mentioned problems existing in the prior art, and provide a kind of intelligent supplementary chlorine disinfection system and the method for supplementary chlorine that fully consider the actual situation of the water tank and are specially applied to the disinfection of tap water in the water tank. The technical problem to be solved is to design a miniature sodium hypochlorite generator with simple structure, easy maintenance, long-term automatic operation, and meeting the disinfection requirements of water tanks based on the existing sodium hypochlorite generator technology. It is a dilution device that is convenient, automatic, and capable of diluting the sodium hypochlorite disinfectant (called disinfection stock solution) produced by the sodium hypochlorite generator to the set concentration. When the residual chlorine concentration of the tap water in the water tank is lower than the set value, it is automatically prepared. The concentration of sodium hypochlorite disinfectant (called available disinfectant) is added to the water tank, so that the tap water in the water tank can continuously maintain sufficient residual chlorine concentration
