摘要
以酸/碱改性和Cu负载活性炭为催化剂,采用微气泡催化臭氧氧化深度处理化工园区废水。结果表明,经该工艺处理后,出水COD降至20 mg/L以下,发光抑制率降至-1.2%^-7.3%,B/C升至0.29~0.37,消除了废水生物毒性,并提高了废水可生化性。硝酸改性并负载Cu组分活性炭具有更强的催化活性,COD去除率和去除负荷分别可达70.8%和0.478 kg/(m^3·d),臭氧利用率为97.5%,催化臭氧氧化反应效率为0.554 mg COD/mgO_3。
The micro-bubble catalytic ozonation process has been applied to the advanced treatment of wastewater from chemical industrial parks,using acid/alkali modified and Cu-loaded activated carbon as catalyst. The results show that after treated by this process,the effluent COD is reduced to less than 20 mg/L,luminescence inhibition rate decreased to-1.2%-7.3%,B/C increased to 0.29-0.37,the wastewater bio-toxicity eliminated and wastewa-ter biodegradability improved. Since the nitric acid modified and Cu-loaded activated carbon has stronger activity , the COD removing rate and removal loading can reach 70.8%and 0.478 kg/(m3·d),respectively,the ozone utiliza-tion rate is 97.5%and catalytic ozonation efficiency 0.554 mgCOD/mgO3.
