摘　　要：采用臭氧微-纳米气泡技术对两种质量浓度(83.3 mg/L和166.7 mg/L)的苯酚溶液进行处理,旨在探究不同盐浓度对总有机碳(TOC)去除效率的影响。在pH值为7.0~9.0、氧化还原电位(ORP)≤300 mV的条件下进行实验,覆盖了0~47000μS/cm的电导率范围。结果表明,在高盐环境(即高氯离子浓度)下,臭氧微-纳米气泡技术处理苯酚的效率基本不变。通过对两种不同盐浓度梯度的苯甲酸溶液的降解实验,进一步验证了该实验结论。臭氧微-纳米气泡技术在高盐条件下依然保持高效的有机物降解能力,表明其在高盐废水处理领域有着重要的应用前景。This study utilized ozone micro-nano bubble technology to treat phenol solutions of two concentrations(83.3 mg/L and 166.7 mg/L),aiming to explore the impact of varying salt concentrations on the efficiency of total organic carbon(TOC)removal.The experiments were conducted under controlled conditions with a pH value of 7.0 to 9.0 and an oxidation-reduction potential(ORP)not exceeding 300 mV,covering a conductivity range from 0 to approximately 47000μS/cm.The results indicated that under high-salinity conditions(i.e.,high chloride ion concentration),the efficiency of phenol treatment via ozone micro-nano bubble technology was essentially unaffected.Furthermore,by degrading solutions of benzoic acid with two different salinity gradients,the experimental conclusion was further validated.Therefore,due to its sustained high efficiency in organic matter degradation under high-salinity conditions,ozone micro-nano bubble technology promises significant application prospects in the future industrial treatment of high-salinity wastewater.
