臭氧电磁高级催化氧化去除难降解有机物的研究

Treatment of Biorefractory Organic Compounds by Ozone EM Advanced Catalytic Oxidation Technology

臭氧电磁高级催化氧化技术是一种新型的水处理技术，适用于去除溶解性难生物降解有机物。采用该技术处理某化工区综合污水处理厂的尾水，中试结果表明，在进水COD为70～110mg／L、臭氧投加量为25mg／L的条件下，出水COD在45mg／L以下，处理成本为0．41元／m^3，证明该技术是可行的。另外，试验结果还显示，曝气生物滤池作为臭氧电磁高级催化氧化工艺的后续工艺，其对COD的进一步去除效果并不明显。

Ozone EM advanced catalytic oxidation technology is a new wastewater treatment technology, suitable for removing biorefractory organic compounds. The technology was used to treat the effluent from a complex wastewater treatment plant in a chemical industrial zone. The pilot test results indicated that when the influent COD was 70 to 110 mg/L, and the ozone dosage was 25 mg/L, the effluent COD was less than 45 mg/L, and the treatment cost was 0.41 yuan/m3. In a follow-up process, the removal of COD by the BAF was not obvious.
