摘要
[目的]对炼化公司含盐污水采用COBR工艺开展深度处理中试研究。[方法]采用工艺参数优化、组合工艺正常连续运行、组合工艺冲击试验3个阶段对COBR工艺的深度处理效能进行研究。[结果]在臭氧投加量为55 mg/L,臭氧催化氧化池、稳定池和内循环BAF水力停留时间分别为1.7、1.0和3.0 h的工艺条件下,当进水水质COD≤130 mg/L时,出水COD、氨氮可分别控制在50、1 mg/L以下。当进水浓度升高、波动较大时,深度处理系统仍具有很强的抗冲击能力。[结论]该研究可为现有含盐污水深度处理系统的升级改造提供技术参考。
[Objective] The research aimed to undergo pilot-scale study of petrochemical salinity-contained wastewater from Huizhou refinery company with COBR technology.[Method] Processes of technological parameter optimization,regular and continuous operation of group technology,impulse test of group technology were adapted to study the advanced treatment effects of COBR technology.[Result] The results showed that under the circumstance of ozone dosage at 55 mg/L,the hydraulic retention time of ozone catalytic oxidation ponds,stabilization ponds and internal circulation biological aerated filter at 1.7,1.0 and 3.0 h,and when the influent COD ≤ 130 mg/L,the effluent COD and ammonia could be controlled below 50 mg/L and 1 mg/L,respectively.The advanced treatment system proved a strong impact resistance when an increase in the influent concentration with a wide fluctuation occurred.[Conclusion] This research could provide technological references for the upgrading and rebuilding of petrochemical salinity-contained wastewater advanced treatment systems.
