Abstract

The invention discloses a biological verification ultraviolet dose system and method. The system comprises a water inlet pipe, an ultraviolet reactor, a regulator feeding facility and a microorganismfeeding facility; the water inlet pipe is connected with a static mixer, the water inlet pipe is connected with the regulator feeding facility and the microorganism feeding facility, the static mixeris connected with the ultraviolet reactor, and sampling ports are formed in a water inlet and a water outlet of the ultraviolet sensor. The system is simple in structure and small in occupied area, actual ultraviolet energy which can be output to microorganisms in water by ultraviolet equipment can be rapidly, scientifically and reasonably determined through the system, and the disinfection performance of the equipment can be truly reflected.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a system and a method for biological verification ultraviolet dosage. Background technique [0002] Ultraviolet disinfection technology is a kind of physical disinfection, which has the advantages of broad-spectrum sterilization, no secondary pollution, safe and reliable operation, etc. It can inactivate some harmful microorganisms that cannot be killed by traditional chemical agents. Therefore, more and more water supply plants use it This disinfection technique is used to increase the coverage of microbial control. At present, there are mainly several methods to identify the disinfection performance of ultraviolet equipment (the method of projected ultraviolet dose): calculation model method, chemical method, biological method, fluorescent microsphere method and ultraviolet intensity monitoring method. Most of these methods rely on theoretical UV dose desig...
