Hydrogen Peroxide Increasing BOD

Hydrogen peroxide is effecting the biochemical oxygen demand (BOD) in our activated sludge plant.  The local jail is using hydrogen peroxide for the laundry service they provide for inmates' clothing. I need help with resolving the issues with high BOD. How can I reduce it? How can I mitigate the effects of hydrogen peroxide?  The treatment plant is an activated sludge plant with selector cells for nutrient removal. The final effluent is filtered through MBR's and the water is either reused or injected back into aquifer. The plant is considered a Class A reclaimed water facility.
