Dissolved air flotation machine for use in the process of pretreatment equipment is a very commonly used in sewage treatment, when making use of its main principle is to use the small bubbles dissolved air system, with the suspended solids in the wastewater, oil contact, under the action of air bubble buoyancy impurities to the surface, through scraping slag device from the purpose of purifying water quality. It is commonly used in pretreatment works in slaughtering, food, paper making, washing, oil, printing and dyeing, aquaculture, etc. It is also used in the deep purifying section of water outlet.
Preparation before the installation of the dissolved gas air float system.
1. Check the goods according to the shipping list, check the appearance of equipment for deformation, damage, welding and other problems.
2. Check whether the equipment foundation is flat and the foundation strength can withstand the weight of the equipment running. For laying the foundation of the equipment, it is necessary to ensure the structural strength of the supports to meet the requirements.
The installation precautions of the dissolved gas air float system.
1. Equipment hoisting in place. Embedded iron is fixed with embedded iron.
2. Connect the pipe and pay attention to the installation direction of the dissolved gas reflux pump.
3. Connect the control power of each electromechanical device.
4. Dredge pipe shall be arranged according to the length of the distance to prevent the blockage of the pipe.
5. The electric control cabinet should be placed where convenient operation is used.
Installation, debugging and precautions of the dissolved air system for air - dissolved air float.
1. The dissolved air system must lay down the foundation before installation. And the concrete mortar pad is 100-150mm high. It can also be installed, but the foundation must be able to bear the weight of the equipment.
2. Adjust the level after the equipment is in place.
3. The equipment shall be equipped with a cleaning drain, open channel and direct pipe to the regulating tank to flush the water out of the air tank.
4. The connection pipe between the sewage inlet and the reaction tank shall be as short as possible so as not to be damaged in the pipe.
5. Clear water outlet can be connected with sewage discharge. If it needs to enter the next processing procedure, it can be directly connected with the next processing equipment.
6. Sludge outlet can be connected to sludge tank or sludge treatment equipment.
7. The electrical box should be placed on the side of the escalator, and the environment should be clean and clean.http://www.shallowairfloatation.com/
