First, the device overview
Floatation machine is mainly applicable to all types of wastewater floes close to the proportion of waste water treated by the reaction, widely used in mechanical, chemical, textile, transportation, food and other industries, especially for oil drilling sewage, oil field injection refinery wastewater treatment.
Floatation machine main treatment process using physical and chemical methods. The chemical method, flotation, filtration, adsorption and other traditional mature technology through a combination of organic design made. Process is simple and reasonable, wide adaptability, compact structure, easy transportation and installation, easy operation and reliable performance characteristics. Oil and water separation, removal of suspended solids, COD, BOD's have a good effect, generally treated wastewater can meet emission standards.

Third, the principle
Wastewater pollutants into non-dissolved organic matter and dissolved substances (ie SS), dissolved organic matter, under certain conditions, can be transformed into a non-solution solution substance, one method of sewage disposal is the addition of coagulants and flocculation agent to convey most of dissolved organic matter into non-soluble substances, then all or most of the non-solution solution substance (ie SS) removed to achieve the purpose of purifying contaminated water, and the main method is the use of flotation to remove SS method .
CXGY is generated by air flotation process. Aerators will "microbubbles" injected directly into the water without the need to advance the dissolved air, and then by casting stainless steel impellers bulk gas "microbubbles" are uniformly distributed in the sewage, so it will not happen obstruction, untreated wastewater first enters the aeration inflatable section, and "microbubbles," mixed, "micro bubbles" in the process of rising, the suspended solids to the surface. Scraper along the surface motion, the suspension was blown inclined metal plate, then push it into the sludge discharge pipe. Sewage purified before being discharged via the overflow tank will swash plate below the overflow tank is used to control the water level in the flotation tank to ensure that the liquid does not flow into the tank sludge discharge pipe.
Open return line from the aeration section extending along the bottom of the flotation tank. While generating microbubbles, aeration opportunity with a reflux pipe forming a bottom region of negative pressure, this negative pressure causes the water back from the bottom of the pond to the aeration zone, then back floatation section, the return conduit on a one-way valve that will not enter the aeration tank of sewage without treatment directly into the flotation tank from the return pipe. The whole process to ensure that in the absence of the inflow, air is still ongoing. The procedure has not been removed tiny fraction of floc or SS, turbidity, BOD part, COD, etc. can be pumped into the filter column removed, filtered filler (quartz sand) with backwash water within the column. Water flows through the pump into the filter column adsorption column in the adsorption column (packing with backwash water) columnar activated carbon adsorption not only difficult to break down organic matter to further reduce BOD, COD, SS, etc., but also the waste water bleaching, deodorization, ultimately achieve the waste water can be reused or discharge.
