An advanced oxidation process (AOP) combining hydrogen peroxide and microwave heating was used for the solubilization of phosphate from secondary municipal sludge from an enhanced biological phosphorus removal process. The microwave irradiation is used as a generator agent of oxidizing radicals as well as a heating source in the process. This AOP process could facilitate the release of a large amount of the sludge-bound phosphorus from the sewage sludge. More than 84% of the total phosphorous could be released at a microwave heating time of 5 min at 170 degrees C. This innovative process has the potential of being applied to simple sludge treatment processes in domestic wastewater treatment and to the recovery of phosphorus from the wastewater.
一种将过氧化氢与微波加热相结合的高级氧化工艺（AOP）被用于从强化生物除磷工艺产生的城市二级污泥中溶解磷。在该工艺中，微波辐射既作为氧化自由基的产生剂，又作为加热源。这种AOP工艺能够促进污水污泥中大量与污泥结合的磷的释放。在170℃下微波加热5分钟时，总磷的释放率可达84%以上。这种创新工艺有潜力应用于生活污水处理中的简单污泥处理过程以及从废水中回收磷。
