What items does Chengdu water treatment certificate physical examination do?

Need to be a sewer repairman, sewage chemist, plumber, sewage laboratory monitor, water treatment and operation of these projects.

A method for treating industrial sewage belongs to the technical field of sewage treatment. Introduce sewage into the water collection tank, adjust the pH value of the last cell of the water collection tank, pump the first-stage dissolved air pump to the first-stage pressure dissolved air tank, and suck in air and coagulation decolorant at the same time, so that the first-stage saturated dissolved air water in the first-stage pressure dissolved air tank is suddenly released to the first-stage air flotation tank to form the first-stage treated water.

The primary treated water overflows into the buffer tank, then the primary treated water is pumped into the secondary pressure dissolved air tank by a secondary dissolved air pump to control the pH, and at the same time, air and coagulation decolorant are inhaled, so that the secondary saturated dissolved air water in the secondary pressure dissolved air tank is suddenly released into the secondary air flotation tank to form secondary treated water, which overflows into the sedimentation tank and is discharged after sedimentation.

Treatment method of medical sewage

Hospital sewage treatment usually includes primary treatment and secondary treatment. Generally speaking, if the treated sewage is discharged into the municipal sewer, it is usually only treated at the first level; If the treated effluent is directly discharged into the river, primary treatment and secondary treatment are needed; In areas with strict emission standards, in order to prevent water eutrophication, three-stage phosphorus and nitrogen removal treatment is needed.

Special hospital sewage such as acid wastewater, phase washing wastewater and radioactive wastewater should be strictly collected and treated. In order to alleviate the contradiction of water shortage in some areas, hospital sewage has been deeply treated and recycled. The actual treatment of hospital sewage should comprehensively consider many factors such as sewage source, sewage flow direction, local water supply and so on.
