Vortex Concave Air Floatation Machine Sewage Treatment Air Floatation Machine Equipment

Product overview

The vortex concave air floating sewage treatment equipment adopts the principle of combining mechanical aeration with chemical flocculation to treat all kinds of sewage with different water quality.In some wastewater treatment with light pollutant content, the treated clean water can be recycled or discharged to the standard, if combined with biochemical treatment technology, it can be treated to the standard.Vortex concave air floatation is an excellent sewage treatment technology, which is reasonable in design, convenient in operation and economical in operation.The vortex concave aerator directly infuses the "micro-bubbles" into the sewage without dissolving the gas in advance, and then distributes the "micro-bubbles" evenly in the sewage through the dispersing impeller, so the blocking phenomenon will not occur during the whole operation process.The vortex concave air floatation machine is mainly composed of box, aerator, mud scraping system, etc. It does not need the equipment such as pressure dissolved gas, air compressor and circulating pump.

The main features

1. Save investment, low energy consumption, automatic slag discharge without noise, convenient operation and management.

2. Mainly remove the majority of insoluble COD in sewage, SS that can float (proportion less than water) and SS that can sink (proportion more than water).

3. Compared with the domestic traditional pressurized dissolved gas floating system, it saves the equipment such as dissolved gas tank, air compressor and high-pressure water pump, and the energy consumption is 1/8~1/10 of the conventional air floating system.

4. The system can remove grease, glue and fiber suspension in sewage, reduce the sewage load of BOD, COD and SS, and significantly improve the color of water quality.

5. The system is mainly used for the purification and treatment of industrial sewage in papermaking, chemical industry, printing and dyeing, food, beer, pharmaceutical, slaughtering and other industries.Raw sewage into the aeration zone, first mix with micro bubbles, micro air bubble is on the rise in the process of suspended solids to the surface of the water, mud scraper run along the liquid surface will be suspended to tilt on the metal plate, and pushes it into the sludge discharge pipe groove, through the sludge discharge pipe groove into the sludge collector, scraping mud move only 0.5 KW.After sewage purification, it will pass through the overflow tank under the inclined plate before discharge. The overflow tank is used to control the water level of the air float tank and ensure that the liquid in the tank will not flow into the sludge discharge pipeline. The open throat flow pipeline extends from the aeration section along the bottom of the air float tank.At the same time, the vortex concave aeration will form a negative pressure zone at the bottom of the tank with the backflow pipe. This negative pressure will cause the waste water to flow back to the aeration zone from the bottom of the tank and then return to the air floating section.This process ensures that air floatation continues in the absence of incoming flow.The treatment capacity of this equipment is 5-500m/ hour, and the treatment cost is about 0.3 yuan/ton of waste water.
