摘要： In order to render sewage sludge suitable for beneficial purposes, it must be disinfected and stabilized. EDC deactivation is rapidly becoming a desirable result of any sludge or biosolids treatment process. Disclosed herein is a process of treating sewage sludge so as to stabilize the sludge that involves the presence of an iron-containing compound during dewatering of the sludge. Process embodiments described also achieve biosolid samples that have reduced EDC activity, Other embodiments disclosed involve use of a combination of iron salts ferrate and ferric chloride that are added to wastewater sludge in the dewatering step before heat drying. The biosolids resulting from sludge treated with aniron-containing compound are able to resist putrefaction for more than two to three weeks.
摘要翻译：为了使污水污泥适合用于有益目的，必须进行消毒和稳定。 EDC失活正迅速成为任何污泥或生物固体处理工艺的理想结果。本文公开了一种处理污泥的方法，以便在污泥脱水期间稳定涉及含铁化合物的存在的污泥。所描述的方法实施方案还实现了具有降低的EDC活性的生物固体样品。所公开的其它实施方案涉及在加热干燥之前在脱水步骤中加入到废水污泥中的铁盐和铁氯化物的组合的使用。由含铁化合物处理的污泥产生的生物固体能够抵抗腐败超过两至三周。

摘要： Disclosed is a method for processing waste to render it fit for ultimate disposal. The method comprises first contacting together in a reaction mixture the waste stream, an ammonia source capable of evolving ammonia for treating the waste, Ca(OH).sub.2, pozzolanic chemicals SiO.sub.2, Fe.sub.2 O.sub.3, and Al.sub.2 O.sub.3, and at least one pozzolanic accelerator selected from the group consisting of anionic metal silicates, anionic carbon compounds, anionic boron compounds (borate family), anionic phosphorous compounds (phosphate family), and gelling enhancers, in a manner suitable to cause pozzolanic stabilization reactions to occur thereby increasing the solids percentage of the reaction mixture. Next, the reaction mixture is allowed to reach a target temperature of at least about 90.degree. C., to reach a pH of at least about 11.5, and to evolve ammonia gas, thereby forming a heated mixture. Finally, the exposed surface area to mass ratio of the solids in the heated mixture is increased in a manner suitable to release the evolved ammonia gas, thereby neutralizing a substantial portion of the pathogens present in the waste stream and forming a treated waste stream that is suitable for ultimate disposal.

摘要： A method of treating alkaline industrial by-products, such as red mud generated by Bayer process bauxite refining, is described. Embodiments of the method comprise treating the alkaline industrial by-products with salts of divalent and/or polyvalent cations, thereby lowering pH of the alkaline industrial by-products. The method involves replacement reactions in which relatively insoluble hydroxide salts form precipitates, thereby removing hydroxide ions from solution.
摘要翻译：描述了一种处理碱性工业副产品的方法，如拜耳法铝土矿精炼产生的红泥。该方法的实施方案包括用二价和/或多价阳离子的盐处理碱性工业副产物，从而降低碱性工业副产物的pH。该方法涉及相对不溶性氢氧化物盐形成沉淀物的替代反应，从而从溶液中除去氢氧根离子。
