Knowledge-Intake mode and daily maintenance of dissolved air flotation machine
Dissolved air flotation machine is a solid-liquid separation air flotation equipment used in sewage. In the process of use, it can effectively remove SS, CODcr and other impurities in sewage in water purification, domestic sewage and industrial wastewater treatment. , Dissolved air flotation machine needs to pay attention to daily maintenance in the process of normal use.

The air compressor, clean water pump and foam scraper of the dissolved air flotation machine should be lubricated regularly. Generally, the air compressor will be oiled once every two months, and the oil will be changed every six months. The sewage entering the dissolved air flotation machine It is necessary to add medicine, otherwise the effect is not ideal, and the equipment should pay attention to daily maintenance to improve work efficiency.

The dissolved air flotation machine effectively includes a static mixer. In the process of use, the inlet end of the static mixer is connected with a raw water inlet device, a coagulant addition device, a flocculant addition device, and an air inlet device.

The static mixer The outlet end is provided with a dissolved gas releaser. Dissolved air flotation machine has two air intake methods when it is in use. Dissolved air flotation machine takes in air in front of the pump. This is a pipe drawn from the water pump pressure pipe and returned to the suction pipe. A hydraulic ejector is installed on the branch pipe.

Negative pressure is caused by the ejector, and after the air is sucked in and mixed with waste water, it is sent into the dissolved air tank through the suction pipe and the water pump. Dissolved air flotation machine sucks air and return water together through the pump inlet, and then cuts into fine dissolved air water through the impeller of the pump, and then releases it into milky white dissolved air water through the pressure reducing valve, so that the flocculation particles float up, thereby achieve the purpose of purification.
