Drinking water disinfection and purification system for treating resistant bacteria and resistant genes of antibiotics and technology of drinking water disinfection and purification system

Abstract

The invention discloses a drinking water disinfection and purification system for treating resistant bacteria and resistant genes of antibiotics and a technology of the drinking water disinfection andpurification system. The drinking water disinfection and purification system comprises an ultraviolet ray disinfector, a microporous filter and an electrochemical reactor, wherein a drinking water inlet is formed in the ultraviolet ray disinfector; the ultraviolet ray disinfector is sequentially connected with the microporous filter and the electrochemical reactor through a pipeline; a drinking water outlet is formed in the electrochemical reactor; a T-shaped feeding pipe is arranged on the connecting pipeline between the microporous filter and the electrochemical reactor; and a secondary liquid inlet is formed in the T-shaped feeding pipe. According to the drinking water disinfection and purification system disclosed by the invention, most of bacteria including resistant bacteria of antibiotics are removed through ultraviolet irradiation, and intracellular resistant genes are removed to a certain degree; then dead bacterium bodies and a small quantity of living resistant bacteria areremoved through microporous filtration; and finally soluble extracellular resistant genes and a small quantity of intracellular resistant genes in the water are thoroughly removed through a low-energy-consumption electrochemical oxidation system. The resistant bacteria and the resistant genes in water sources are completely removed, so that the water supply safety is guaranteed, and the drinkingwater disinfection and purification system has a good application prospect.

Description

technical field The invention relates to the technical field of drinking water treatment, in particular to a drinking water disinfection and purification system for treating antibiotic-resistant bacteria and resistance genes and a process thereof. Background technique Although the application of antibiotics has brought many benefits to human beings, the pollution of resistant bacteria and resistant genes caused by the abuse of antibiotics is threatening human health and ecological security. It is estimated that the number of deaths caused by antibiotic-resistant bacteria in the world reaches hundreds of thousands of people every year. The resistance genes in resistant bacteria can spread in the environment through horizontal transfer and other methods. Even if the resistant bacteria die, their naked resistance genes will exist in the environment for a long time and have the potential to be transferred to other pathogenic bacteria. ability. At present, the existence of resi...

Problems solved by technology

However, conventional disinfection processes in waterworks cannot effectively remove resistant bacteria and resistant genes

Although the use of very high disinfection doses of ultraviolet light, chlorine or ozone can effectively kill resistant bacteria, the effect of removing resistance genes is very limited, and it can also induce resistance in common bacteria, and chlorine and ozone disinfection can cause bacterial cells rupture, causing the release of resistance genes into the water column, which in turn increases the risk of resistance gene transmission
