    First, equipment overview

    This equipment is mainly used in the treatment of waste water after reaction floc density close to water of various types of waste water, widely used in machinery, chemical, textile, transportation, food and other industries, especially suitable for drilling wastewater in oilfield, oilfield reinjection water, oil refinery wastewater treatment.

    Physical and chemical method is adopted in the main treatment process of air floatation filtration integrated machine. The traditional mature technology, such as chemical method, air flotation method, filtration adsorption method, and so on, are formed by organic combination. The process has the characteristics of simple and reasonable technology, wide adaptability, compact structure, convenient transportation and installation, convenient operation, stable and reliable performance.

    The removal of oil water separation, suspended matter, COD, BOD has a very good effect, the general wastewater after treatment can reach the discharge standard.

    Two, equipment picture

    Three, working principle

    Pollutants in sewage points for dissolved organic matter and dissolved substances (SS), dissolved organic matter under certain conditions can be transformed material solution for the solution of non, sewage treatment method of is the addition of coagulant and flocculant to make most of the dissolved organic matter convey of non soluble substances, all or most of the non solution solution of substance (SS) to remove to achieve the purpose of purification of wastewater and removal of SS is the main method is the use of air flotation method.

    CXGY is produced by air flotation process. Aeration machine will "microbubbles" directly into the sewage without the need for prior dissolved gas, then through stainless steel casting powder gas impeller "microbubbles" evenly distribution in sewage, so there are no blocking phenomenon, not by the sewage treatment first into the aeration filling, and "micro bubbles" well mixed "micro bubbles" in the process of rising, the suspended solids are brought to the surface.

    The mud scraper is moving along the liquid level, and the suspended matter is scraped to the inclined metal plate, and then the sludge discharge pipe is pushed into the sludge discharge pipe. Purified sewage prior to discharge will be through the inclined plate below the overflow tank overflow launder is used to control the water level in the flotation tank, ensure that liquid tank can not enter the sludge discharge pipe.

    The open reflux pipe extends from the aeration section along the bottom of the air floatation tank. In generating micro bubbles at the same time, aeration opportunities in reflux tank bottom forms a zone of negative pressure, the negative pressure will make the water from the bottom of the pool is returned to the aeration zone, and then return to the air, return pipe is provided with a one-way valve, so that in aeration tank of the sewage is not so as not treated is from the back of the tube directly into the air tank.

    The whole process to ensure that in the absence of flow into the case, the air is still ongoing. The upper road process has not removed the small parts of SS, BOD, turbidity, part of the COD,, and so on can be pumped into the filter column removal, filter column packing (quartz sand) with anti flushing water.

    Filtration column of water outflow through pump into column adsorption, adsorption column (packed with backwashing water) columnar activated carbon can not only difficult to decompose organic matter adsorption, further reduce the BOD, COD, SS, still can make wastewater decolorization, deodorization, and finally to the wastewater to reuse or discharge standards.
