基于"双纳米"技术的含聚污水深度处理现场试验OA

To address the challenges of deep treatment of high-polymer-content wastewater in the Xingbei Oilfield and the difficulty of re injecting treated wastewater from the San mining block into low-permeability reservoirs,this paper proposes a"dual-nanotechnology"water treatment process,namely"nanobubble flotation+nano-silica based fine filtration."An industrial-scale field test,with a capacity of 2 000 m3/d,was conducted at the Juxing Eleven Wastewater Station.The results show that with incoming water having a polymer concentration of 400 mg/L and oil and suspended solids content≤100 mg/L,the treated water consistently had oil and suspended solids content below 5 mg/L,meeting the requirements for deep treatment of polymer-containing wastewater.Additionally,the"dual-nanotechnology"water treatment process demonstrates effective adsorption and filter media regeneration,ensuring continuous and stable operation of the equipment.With its short process flow and high efficiency,the technology significantly reduces construction and operational costs,offering substantial value for large-scale industrial application and promotion.
