The equipment adopts the flotation technology in the treatment of physicochemical principle, and its basic principle is to introduce air into the water, so that a large number of microbubbles are generated in the water and attached to the impurity particles, forming a floating body with a specific gravity less than that of water, which floats to the water surface, thus separating the impurity particles. The high-efficiency air flotation main engine comprises a tank body, a scum collecting device, a static ring and a shunt ring.
Overflow regulating device, walking frame, rotary water inlet pipe, rotary water distribution mechanism, etc. Its advantages are good effect, quick response and less investment, and at the same time, it can fill a lot of oxygen into the water, thus improving the self-purification function of water extraction. The processing system is fully automatic, with simple operation and less daily maintenance workload; The equipment has stable operation and long service life, and can be effectively used for more than ten years.
High salinity wastewater
High salinity wastewater refers to wastewater containing organic matter and at least 3.5% total dissolved solids (TDS), including high salinity domestic wastewater and high salinity industrial wastewater. Mainly from industrial production, domestic water and direct utilization of seawater from food processing plants and chemical plants, as well as the collection and processing of oil and natural gas.
These wastewater not only contain organic pollutants, but also contain a lot of inorganic salts. If these high-salinity and high-organic wastewater are discharged directly without treatment, it will certainly do great harm to aquatic life, drinking water and industrial and agricultural production water. However, the concentration of brine in conventional treatment methods should not be too high, so it is urgent to develop technologies to treat wastewater with higher concentration and high salinity.
