A microwave-enhanced advanced oxidation process using hydrogen peroxide (MW-H2O2-AOP) was used for the solubilization of phosphate and ammonia from secondary municipal sludge. Two sets of experiments were performed to determine the factors affecting nutrient solubilization from sewage sludge. Four factors--microwave heating temperature, heating time, hydrogen peroxide treatment, and sulphuric acid treatment--were incorporated into a screening design to determine which factors were significant for maximizing nutrient solubilization. For phosphorus, the three most significant factors, following the order of significance, were (i) microwave heating temperature, (ii) the combined effect of microwave heating temperature and hydrogen peroxide hydrogen peroxide addition, (iii) microwave heating temperature, and (iv) sulphuric acid addition.
采用过氧化氢微波强化高级氧化工艺（MW-H2O2-AOP）从城市二级污泥中溶解磷和氨。进行了两组实验以确定影响污水污泥中养分溶解的因素。将四个因素——微波加热温度、加热时间、过氧化氢处理和硫酸处理——纳入筛选设计，以确定哪些因素对最大限度地溶解养分具有显著影响。对于磷来说，按显著性顺序排列的三个最重要因素是：（i）微波加热温度；（ii）微波加热温度与过氧化氢添加量的综合影响；（iii）微波加热温度；（iv）硫酸添加量。
