First, use
Flotation technology in recent years is widely used in the drainage and wastewater treatment, it can effectively remove the waste water is difficult to produce frivolous flocs.
Second, the characteristics
1, the large capacity, high efficiency, small footprint.
2, process and device structure is simple, easy to use, and maintenance.
3, elimination of sludge bulking.
4, the flotation aeration to the water, the removal of surfactant and smell have a significant effect, an increase of dissolved oxygen in water due to aeration, provided favorable conditions for subsequent processing.
5, low temperature, low turbidity, the more algae-containing water, the flotation method can get the best results.
Third, it works:
Pollutants in wastewater into dissolved organic matter and non-soluble substances (ie the SS), dissolved organic matter under certain conditions, can be transformed into a non-solution solution of substances, one of the methods of sewage treatment is the addition of coagulants and flocculation agent to convey most of the dissolved organic matter into a non-soluble substances, and then all or most of the non-solution solution of substance (SS) removal of purification in order to achieve the purpose of sewage, and removal of the SS, the main method is the use of flotation approach.
Flotation by the reaction of the dosing of sewage into the mixing zone, mixed contact after the release of dissolved gas and water, floc adhesion in the tiny bubbles, and then enter the flotation zone. Floc in the role of air buoyancy to float downward to the surface of the water the formation of scum, lower water through the catchment flow to the clear water tank, part of the reflux dissolved air, the remaining water flow through the overflow port. Discharged after the flotation water surface scum accumulation to a certain thickness by scraping foam machine, scraping into the flotation machine sludge pool.

4, installation, commissioning and Precautions
(A), the installation
1, equipment installation, you must lay a solid foundation. With concrete mortar booster 100-150mm. Can also be installed overhead, but the fundamentals must be able to bear the weight of the equipment running.
2, the device in place and need to adjust the level.
3, the equipment required to set up cleaning with the sewer, to be tapped open channel can also be a direct pipeline to adjust the pool, in order to flush the water flotation tank discharged.
4, the connection between the pipe in the sewage import and reaction cell as short as possible, to avoid floc in the pipeline is damaged.
Water exports can be connected to sewer emissions, For into the next treatment processes, connecting directly under the processing equipment.
Sludge export can be connected to the sludge tank and sludge treatment equipment.
7, the electrical box should normally be placed in the side of the escalator, the environment should be clean, clean.
(B), debugging:
A, before the commissioning of equipment, should be the following preparations:
To clean the pool all the stolen goods, debris.
Need lubrication pump and air compressor lubrication.
Power, start the pump, check the steering with the arrow marked in the same direction. Manual control to start the compressor, check the air compressor is functioning properly, anomalies for further investigation.
4, press the foam blowing machine switch, so that one end of the walk to the dissolved air system. Run coming to an end after the collision during the journey and the block effect, foam blowing machine reverse walk, hit the block until the sludge tank, trip scraper reveal the stop button to stop scraping foam.
B, the test run:
1, add water: the water level in the flotation machine from the sludge pond baffle along the approximately 20-50mm, flotation tank, the water level, the available catchment regulation.
2, dissolved air system operation: Turn off all control valves, electrical knob switch to the automatic position, start the water pump, air compressor can also enter the automatic working state, then the order to open the lift clean water pump inlet valve, outlet valve, control valves, Gauge pressure is gradually increased, the general should reach 0.4-0.5MPa. Opens the water control valve dissolved gas cylinders, so that the dissolved gas and water through the release, release to the flotation tanks, flotation tanks a large number of fine bubbles, so that water will become milky, dissolved air is the normal system, dissolved air pressure more high, the release of dissolved gas blisters the higher the density. The gas dissolved air system is provided by the air compressor. Dissolved gas and water tank air away, the tank air is gradually reduced, the water level rises. When the water level rises to a certain location, the float level gauge control air compressor so that the tank has sufficient volume of air.
3 flotation running: Dissolved Air System operating normally after dosing reaction sewage sent to flotation pools. Flow first, and gradually increased to normal rating.
4, the dissolved gas and water: dissolved gas water with tap water for back water, normal, clean water after the switch to handle back to the water. Detergent volume such as waste water, foam, affecting the flotation effect, may have been with water.
5, scum accumulates to a certain thickness, start scraping the foam machine.
Equipment downtime, you should first turn off the sewage control valve, then close the sewage pump, Mo scrape, stopping to scrape the foam machine, and then open the water valve, into the tap water run for 30 minutes, turn off the dissolved gas effluent water control valve, and finally stop the clear water pump.
(C) Note and routine maintenance
A pressure gauge reading, the dissolved gas cylinders shall not exceed 0.6MPa.
2, water pump, air compressor, and foam blowing confidential regularly lubricated, general air compressor month plus an oil, half a year oil change.
Flotation tank should precipitate the number of regular cleaning.
Sewage into the flotation machine must be added to the drug, or the result is not satisfactory.
Regular inspection dissolved gas cylinders on the safety valve is working and reliable.
6, the release of clogging, to open the vacuum valve, so that the release tabs to open the self-cleaning, clog wash it with water, and then close the valve, the valve generally only open 10 to 20 seconds.
V. Accessories:
1, product certification
Packing List: (1) machine (2) a distribution cabinet
3, manual
6, the main technical parameters:
The flotation device according to the processing capabilities can be divided into: 5,10,20,30,40,50,60,80,100,150,200,250,300 m3 / h, and other specifications can also be designed according to user needs. m3
