MICRO FLOCCULATING SAND FILTER-CATALYTIC OZONATION ENHANCED COD REMOVAL FROM BIO-TREATED PETROCHEMICAL WASTEWATER

  • 摘要: 为强化石化生化出水COD的去除,采用微絮凝砂滤-臭氧催化氧化工艺处理石化生化出水,比较了臭氧催化氧化反应器不同氧化方式和不同回流比组合方式下COD的去除,开展了臭氧催化氧化深度处理单元小试、中试和生产性规模研究,确立了以双级臭氧催化氧化Ⅰ级自回流工艺(回流比100%)为双级臭氧催化氧化推荐的优化工艺。生化出水ρ(COD)为70~120 mg/L时,微絮凝砂滤出水ρ(COD)达到65~113 mg/L,Ⅱ级氧化出水COD平均去除率达到35.0%~42.6%,出水满足GB 31571-2015《石油化学工业污染物排放标准》排放限值要求。生产性试验条件下,优化工艺装置去除单位COD消耗臭氧量平均为1.04 g/g,比对照组现阶段生产工艺(仅Ⅰ级臭氧曝气)降低了21.2%。
