A baffle type adjustable ultrasonic/ultraviolet combined disinfection reactor

Abstract

The invention provides a baffled regulable ultrasonic / ultraviolet combined disinfection reactor, belonging to the field of sewage and sludge treatment. The device utilizes ultrasonic and ultraviolet combined action, and by utilizing the crushing, cavitation and mechanical shearing action of ultrasonic wave, the particle size distribution state of particulate matters in sewage can be improved, the ultraviolet is forced to kill pathogenic bacteria, so that the ultraviolet disinfection efficiency and stability can be improved. The contact time of water flow and a disinfectant can be prolonged as water flow is baffled to pass through all reaction chambers of the reactor, multistage reaction processes can be formed, and the controllability of reaction processes can be enhanced. Through the technology, the side product risk brought by the disinfection of chemical medicaments can be greatly lowered, the baffled regulable ultrasonic / ultraviolet combined disinfection reactor is especially applicable to disinfection treatment of small and middle-sized sewage treatment plants, the technical operation is simple, auxiliary equipment facilities are not required, so that the baffled regulable ultrasonic / ultraviolet combined disinfection reactor is safe and high-efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage and sludge treatment, in particular to a baffle type adjustable ultrasonic / ultraviolet combined disinfection reactor. Background technique [0002] Due to its high efficiency, no disinfection by-products, and no secondary pollution to water, ultraviolet disinfection technology has developed rapidly in recent years and has been more and more used. The principle is to use ultraviolet rays (UVC) of appropriate wavelengths to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms, causing growth cell death and (or) regenerative cell death, to achieve sterilization Effect. The main factors affecting the disinfection effect of ultraviolet rays are water quality conditions and microbial types. In addition, the design and operation of the ultraviolet system will also affect the disinfection effect. After the sewage has undergone primary and...

Problems solved by technology

However, this also increases the investment and operation cost of ultraviolet disinfection, which does not meet the economical requirements of the disinfection process

In addition to water quality conditions, UV lamp scaling and UV lamp life decay lead to weakening of UV intensity will also affect the effect of UV disinfection operation

[0003] After searching the existing technology, it is found that the new technology for sewage disinfection in order to improve the efficiency and reduce the by-products has been studied in recent years, but the application is still lacking.
