QDEVU Dissolved Air Flotation Machine(DAF)
Description
For different wastewater, by adding appropriate agents, can remove 90%-95% of suspended solids, oil, colloid; Removal of 30%-80% COD (reagent use and removal efficiency need to be determined by experiment); Add decolorizing agent, phosphorus removal agent, heavy metal capture agent, can effectively remove chroma, phosphate ion and heavy metal ions.
Application
Petrochemical wastewater, electroplating wastewater, textile printing and dyeing wastewater, food processing wastewater, catering wastewater, municipal wastewater, machinery processing wastewater, slaughtering and processing wastewater, papermaking wastewater, vegetable oil production wastewater, dairy production wastewater, tanning wastewater, biochemical precipitation, phosphorus removal, river and lake algae removal and phosphorus removal.
Working principle
No need air compressor, through the special structure of the dissolved air pump, realize the side into the water, side air inlet, air and water mix by high-speed rotating impeller, line into saturated dissolved air water, saturated dissolved air water into the dissolving tank, dissolved gas through dissolving tank at the top of the exhaust valve discharge tank, prevent into the backend release area big bubbles. Saturated dissolved gas water enters the release zone through the release device to release decompression and produce a large number of small bubbles. In the process of floating, small bubbles contact with suspended floc and oil in sewage and form large particles of floc. With the bubbles floating to the surface, the scum is pushed to the slag removal system through the round-trip movement of the scum scraper, and the scum is discharged to the sludge tank. The purified sewage is discharged through the baffle and overflow tank.
Features
1. No air compressor, low power consumption of equipment.
2. High processing efficiency and small footprint.
3. Can be customized, high degree of automation.
4. Automatic slag scraping, slag, stable operation.
5. Small bubbles, high gas dissolving efficiency, oil and suspended matter removal up to 90%-93%.
