vortex concave air flotation machine
The vortex concave high-efficiency air flotation machine is used to remove solid suspended solids, grease, colloids and other impurities in industrial and urban sewage. This machine is most suitable for pre-treatment of various sewage. It is more effective than traditional biochemical treatment in removing fat and suspended solids. It can also minimize the pollution generated in sewage by adding appropriate chemicals for different sewage. By-products can also be recycled and reused.
Applicable scope Paper making, tanning, textile printing and dyeing Suspended solids are divided into petroleum, chemical industry, power plants, metallurgical oil and water separation, food, brewing, medicine Coagulation reaction floc is divided into urban sewage treatment and reuse activated sludge floc The original treated sewage first flows into the aeration section equipped with an aerator. During the rising process, the sewage is fully mixed with micro-bubbles through the aeration section. Due to the density imbalance between the air-water mixture and the liquid, a vertical upward flow is generated. Buoyancy, which brings suspended matter to the surface. During the floating process, microbubbles will attach to the suspended matter. After reaching the water surface, the suspended matter relies on these bubbles to support and maintain it on the water surface. The suspended solids floating on the water are intermittently removed by the chain scraper. Advantages
◆ Save investment. The vortex concave high-efficiency air flotation machine does not have pressure vessels, air compressors, circulation pumps and other equipment, so the equipment investment is small. The equipment occupies a small area and reduces civil construction investment.
◆ Economical and affordable. This system saves power consumption because it does not have pressure vessels, air compressors, circulation pumps and other equipment. The system is very easy to operate and has no complicated equipment at all. Therefore, the workload of manual operation and maintenance is very small, which reduces labor and maintenance costs. Due to the simplicity and completeness of the system, it can be installed on the ground, underground or at height and takes very little time.
◆ High efficiency Contrary to traditional gravity settling tanks and separation tanks, the vortex air flotation system automatically and continuously removes solid sludge from wastewater. The removal and storage of sludge is carried out in a concentrated manner, thus reducing the cost of sludge treatment.
◆ The odor reduction vortex concave high-efficiency air flotation machine treats wastewater through an aerobic process, and the odor problem generated has been well solved. Since the sludge is removed in a fresh state, it increases the possibility of solid reuse and reduces disposal hassles.
◆ The treatment effect is remarkable, the removal rate of petroleum and suspended solids exceeds %.
The removal rate can reach more than %.
It can promote the oxidation of sulfides and reduce the sulfur content in sewage.
Structural features
The system does not require dissolved gas devices, releasers, etc., saving investment and low operating costs.
, advanced technology, high treatment efficiency, good effluent quality, suspended solids content can be lower than /.
. It has strong adaptability to changes in water quality and quantity.
Inflating air into the raw water makes the fine bubbles and flocs adhere better, thereby improving the effect of solid-liquid or liquid-liquid separation.
, simple structure, reliable operation, easy operation and maintenance, and small footprint.
