This invention discloses a biochemical treatment device and method for producing water from high-salinity gas fields via MVR distillation. The device includes a base, a biochemical tank at the top of the base, a support frame on the side of the base, and a collection mechanism below the support frame that automatically detects and collects excess sludge. A sealing mechanism is installed on the side wall of the biochemical tank, and a filter plate is installed inside the tank. This invention, through the configuration of a drive motor, an electric telescopic rod, a fan-shaped collection chamber, a first trapezoidal block, a contact rod, a reciprocating switch, and a second trapezoidal block, achieves automatic cleaning when the sludge reaches half the capacity of the biochemical tank, preventing a reduction in tank volume from affecting biochemical treatment efficiency. Furthermore, the adjustment mechanism gradually increases aeration as aerobic bacteria multiply, ensuring sufficient oxygen for nitrification and maintaining the wastewater treatment efficiency of the biochemical tank. This adaptive adjustment requires no manual intervention and is convenient and quick.

A method for treating wastewater generated by vehicle wash facilities is provided. The method comprises subjecting wastewater to hydrodynamic cavitation and generating, based on the cavitation, hyper-oxygenated water with nanobubbles possessing positive and negative charges. The method also comprises introducing biological agents into the hyper-oxygenated water and catalyzing reactions, facilitated at least by the biological agents, between the nanobubbles and impurities in the hyper-oxygenated water, the catalyzing causing attachment and disintegration of soil particles and contaminants. The method also comprises utilizing the hyper-oxygenated water to promote aerobic bacterial growth while suppressing anaerobic bacteria, the bacteria generating hydrogen sulfide gas (H2S). The method also comprises reusing the hyper-oxygenated water in the vehicle wash process. The hydrodynamic cavitation generates nanobubbles that attach to impurities, facilitating their breakdown of the impurities and removal of the impurities from the wastewater. The biological agents are aerobic bacteria that outcompete anaerobic bacteria, reducing odors.
