In order to make the sewage to meet the discharge of a certain body of water or re-use of water quality requirements, the choice of ultraviolet disinfection equipment can achieve the purpose of disinfection and sterilization. In the selection of sewage treatment ultraviolet disinfection equipment, the first to determine the following:
(1) treatment of water quality
In accordance with the source of sewage water to points, sewage treatment mainly includes the production of sewage treatment and
Life sewage treatment
. The former refers to industrial sewage treatment and hospital sewage treatment, domestic sewage mainly refers to the sewage generated by daily life, municipal sewage treatment. Sewage water quality includes TSS, i.e., suspended solids in water, type of sewage and proportion. Different types of sewage, water quality is also different, in the selection of ultraviolet disinfection equipment, should be different configurations.
(2) treatment of water, discharge standards
Water refers mainly to the average flow of sewage to be treated and peak flow. Secondly, it is to consider the equipment running time is 24 hours of operation or intermittent water supply. In addition, it is also necessary to consider the water quality requirements of the discharge standard and sewage in and out of the water when the bacterial indicators and requirements of the sewage treatment of ultraviolet disinfection equipment required for the number of modules, modules contain the number of lamps and modules discharge distance and other specific design.
Because the sewage treatment ultraviolet disinfection using
Ultraviolet germicidal lamp
the number of more, at the same time, the number of ultraviolet ballasts is also more, more complex equipment line, sewage treatment ultraviolet disinfection control part is also more complex, therefore, in the selection of equipment, must first determine the amount of water treatment, water quality, discharge standards and other factors.
