摘要： A process is disclosed for recovering elemental phosphorus from an aqueous sludge and converting the residue into non-hazardous waste. The sludge is separated into (1) a slurry of water containing suspended phosphorus and dirt particles and (2) coarse solids. A flocculating agent is added to the slurry to agglomerate the suspended phosphorus and dirt particles, which are recovered from the water and are heated to melt elemental phosphorus. A coalescing agent is added to coalesce the melted elemental phosphorus, which is separated from the dirt particles. The coarse solids are mixed with hot water to melt the phosphorus sludge in it, which is then separated from inert solids. The solids are heated to burn any residual elemental phosphorus. The separated molten phosphorus sludge is stirred with a solution of chromic acid to recover the phosphorus as a separate phase. A reducing agent is added to the remaining water and solids to reduce the Cr +6 to Cr +3 . Finally, an alkali is added to the water and solids to react the residual phosphorus and form phosphorous compounds. The reaction mass is filtered and the filter cake can be placed in a landfill as a non-hazardous waste.
摘要翻译：公开了从含水污泥中回收元素磷并将残余物转化为无害废物的方法。污泥被分离成（1）含有悬浮磷和污垢颗粒的水的浆液和（2）粗固体。将絮凝剂加入到浆料中以使悬浮的磷和污物颗粒聚集，这些颗粒从水中回收并被加热以熔化元素磷。加入聚结剂以使熔融的元素磷与污垢颗粒分离。将粗固体与热水混合以熔化其中的磷污泥，然后将其从惰性固体中分离出来。将固体加热以烧制任何残留的元素磷。将分离的熔融磷污泥与铬酸溶液一起搅拌以回收磷作为分离相。将还原剂加入到剩余的水和固体中以将Cr +6还原成Cr +3。最后，向水和固体中加入碱以使残余的磷反应形成磷化合物。将反应物质过滤并将滤饼作为无害废物放置在垃圾填埋场中。

摘要： A process for treatment of waste containing organic material, phosphorous and water in suitable amounts to be a pumpable sludge and in order to be oxidizable through supercritical water oxidation, comprises the steps of: putting the sludge into conditions being supercritical for water; adding oxidant, particularly, oxygen to the sludge, wherein the organic material contained in the waste is substantially completely oxidized by means of supercritical water oxidation; separating the phosphorous from water and from carbon dioxide formed during the oxidation; and recovering the phosphorous by means of dissolving the phosphorous in an alkali.
