- A novel and safe method has been reported for wastewater sludge treatment, the first step of which is H2O2 pretreatment at 150 cm3kg for 80 min. In this step, the majority of organic substrate was degraded, and the shear stress diminished significantly. In the second step, Aspergillus oryzae further decomposed the organic substrate of sludge for 8 days, and the activities of manganese peroxidase and lignin peroxidase kept increasing. By the methods, the residual chemical oxygen demand (COD) in the sludge was much lower than that in the sludge treated with high doses of H2O2. These results indicate that the present study provides a feasible method to safely dispose sludge from the wastewater treatment plant.
