AI Technical Summary
The existing weak swirling dissolved air flotation process has poor swirling field stability when treating desalinated wastewater. It is affected by fluctuations in influent flow rate and oil content, resulting in unstable separation effect and problems such as scum entrainment, microbubble destruction, short flow and dead water zone. It is difficult to efficiently treat high oil content and highly emulsified desalinated wastewater.
A real-time deep wastewater treatment device and process are adopted after an atmospheric and vacuum desalination device. By setting up components such as diversion components, guide plates, seals, foaming equipment and oil floating plates, a stable swirling field is formed. Combined with a multi-stage air flotation process, the efficient separation of emulsified oil and suspended solids is achieved.
It improves the stability and processing efficiency of oil-water separation, avoids uncontrolled vortex flow, short flow and dead water zone, ensures that the effluent water quality meets the standards, and adapts to the daily and extreme operating conditions of the electrostatic desalination unit.
