为了实现高浓度脂肪胺废水的资源化利用,采用催化吹脱耦合A/O工艺对脂肪胺废水进行处理。考察了温度、时间、pH值、催化剂投加量因素对吹脱效果的影响。试验结果表明:进水ρ(COD)为2 000~3 000 mg/L,温度为50℃,时间为2 h,pH值为11,催化剂投加量为5%的条件下,催化吹脱TKN去除率为83%。经催化吹脱工艺处理后废水采用A/O工艺处理,出水各项指标均达到国家污水综合排放一级标准,催化吹脱耦合A/O工艺对脂肪胺废水的处理是可行的。
In order to realize the resource utilization of high concentration fatty amine wastewater, the fatty amine wastewater was treated by catalytic stripping A / O. The effects of temperature, time, pH value and dosage of catalyst on stripping effect were investigated. The results showed that TKN was catalyzed and desorbed under the conditions of influent ρ (COD) of 2 000-3 000 mg / L, temperature of 50 ℃, time of 2 h, pH value of 11 and catalyst dosage of 5% The removal rate is 83%. The wastewater treated by the catalytic stripping process was treated with A / O process. The indicators of the effluent met the first-class national standard for comprehensive wastewater discharge. The treatment of fatty amine wastewater by catalytic stripping A / O process was feasible.
