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, the significance of model:
YW


Processing capacity: m3 / h


Feature Code: flotation device

Fourth, 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

V. How 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.

6, 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.
Pollutant removal by flotation processing the following table:
