The disintegration of waste active sludge was investigated by photo‐Fenton processes. A batch study was conducted to evaluate parameters, such as Fe2+ and Fe0 ions and H2O2, governing the activated sludge integration by the photo‐Fenton process. Under optimum conditions, the concentration of soluble chemical oxygen demand (SCOD) with the classical Fenton process (CFP) increased very rapidly in the first five minutes due to the sufficient presence of reaction components in the medium, and then the rate of increase declined. In the modified Fenton process (FTP), the SCOD concentration increased more slowly as metallic iron powder must first be dissolved. The photo‐Fenton process proved to be a feasible and efficient process for the disintegration of waste sludge.

Fe2 +和Fe0施加的光芬顿工艺对污泥分解的影响
用光芬顿法研究了废活性污泥的分解。进行了批量研究以评估参数，例如Fe 2+和Fe 0离子以及H 2 O 2，通过光芬顿法控制活性污泥的整合。在最佳条件下，由于介质中反应成分的充分存在，经典Fenton工艺（CFP）产生的可溶性化学需氧量（SCOD）浓度在开始的五分钟内非常迅速地增加，然后增加速率下降。在改进的Fenton工艺（FTP）中，由于必须首先溶解金属铁粉，因此SCOD的浓度增加得更慢。光芬顿法证明是一种可行的，有效的废渣分解方法。
