Ultraviolet disinfection water treatment system and method capable of automatically adjusting ultraviolet irradiance

Abstract

The invention discloses an ultraviolet disinfection water treatment system and method capable of automatically adjusting ultraviolet irradiance. The system comprises a water treatment tank. A water inlet pipe, a water outlet pipe, an ultraviolet irradiatometer and an online water quality detector are arranged on the side wall of the water treatment tank. A plurality of thin-walled retaining wallsand a steel frame are arranged on the inner wall and the top of the water treatment tank respectively, and a plurality of submerged ultraviolet lamps and ultraviolet sleeves are arranged at the bottomof the steel frame. Water to be treated enters the water treatment tank from the water inlet pipe, flows through the thin-walled retaining walls to form large vortexes, is disinfected by the ultraviolet lamps and finally flows out through the water outlet pipe. The power of the ultraviolet lamps is automatically controlled in two ways through the ultraviolet irradiatometer, the online water quality detector and a control computer, the ultraviolet lamps are automatically cleaned, and efficient, low-carbon and energy-saving disinfection is achieved. The ultraviolet lamps can be scientifically arranged and distributed, so that the disinfection action time is prolonged, the water body is further purified, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to an ultraviolet disinfection water treatment system and method for automatically adjusting ultraviolet irradiance. Background technique [0002] Ultraviolet disinfection uses ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, causing growth cell death and (or) regenerative cell death, to achieve the effect of sterilization and disinfection. Ultraviolet disinfection technology is based on modern epidemiology, medicine and photodynamics. It uses specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet light to irradiate flowing water to sterilize various bacteria, viruses, parasites, algae and other bacteria in the water. Other pathogens are directly inactivated. [0003] In the traditional ultraviolet disinfection pool, the ultra...
