H2O2 process on the biodegradability of aqueous linear alkylbenzene sulfonate (LAS) were studied. It was observed that the photochemical pre-treatment of the LAS solutions by UV-254/H2O2 increased the biodegradability of LAS solutions. Aqueous solutions with higher concentrations of LAS (> 100 mg/L) were non-biodegradable. The ratio of BOD5/COD of the pre-treated LAS solutions was increased, indicating that the pre-treated LAS solutions were more biodegradable. This ratio was improved as the LAS solutions were more pre-treated. Also, the biodegradability factor for the pre-treated LAS solutions was increased as the time of the photochemical pre-treatment was increased."> 中试装置光化学预处理(UV/H2O2)对线性烷基苯磺酸水溶液生物降解性的影响 - raybet雷竞app,雷竞技官网下载,雷电竞下载苹果

中试装置光化学预处理(UV/ H 2 O 2 )对线性烷基苯磺酸水溶液生物降解性的研究

摘要

采用中试装置UV/ UV对光化学预处理的效果进行了研究 H 2 O 2 研究了线性烷基苯磺酸水溶液的生物降解性能。用UV-254/光化学方法对LAS溶液进行预处理 H 2 O 2 提高了LAS溶液的生物降解性。较高浓度的LAS水溶液( > 100 mg/L)不可生物降解。的比例 生化需氧量 5 /COD增加,说明预处理后的LAS溶液具有更好的可生物降解性。随着LAS溶液预处理程度的提高,这一比例得到了改善。光化学预处理时间越长,LAS溶液的生物降解系数越高。
