    • The invention describes a new method for treating sludge, which can result in the production of high nitrogen organically-augmented inorganic fertilizer that incorporates municipal sludges or biosolids or organic sludges that can compete with traditional fertilizers such as ammonium phosphate, ammonium sulfate and urea on the commodity fertilizer marketplace. The method takes advantage of the thixotropic property of dewatered biosolids or organic sludge to create a pumpable paste-like material from the biosolids or organic sludge that is then treated with an oxidizer to reduce odorant effects and an acid. This mix is then interacted with concentrated sulfuric and or phosphoric acids and an ammonia source or alternatively a hot or molten melt or salt of ammonium sulfate/phosphate to form a fertilizer mix. The present invention controls the heat, atmospheric pressure and retention time of the fertilizer mix in the reaction vessel. When a fertilizer melt is formed ammoniation is subsequently completed by the specific use of vaporized ammonia. The invention can also be an add-on to commercial production of ammonium salts. The fertilizer produced by the present invention contains more than 8 wt. % nitrogen and preferably 15 wt. % nitrogen. The invention is oriented to be tailored to the biosolids production for individual municipal waste treatment plants in order to keep the fertilizer manufacturing plants of the present invention small with a minimization of logistics and liability.
    • 本发明描述了一种用于处理污泥的新方法,其可以产生高氮有机增强的无机肥料,其包含可与传统肥料如磷酸铵,硫酸铵和尿素竞争的市政污泥或生物固体或有机污泥 商品化肥市场。 该方法利用脱水生物固体或有机污泥的触变性质,从生物固体或有机污泥中产生可抽出的糊状材料,然后用氧化剂处理以减少气味效应和酸。 然后将该混合物与浓硫酸和/或磷酸和氨源或热或熔融的熔融物或硫酸铵/磷酸盐形成一种肥料混合物相互作用。 本发明控制肥料混合物在反应容器中的热,大气压力和保留时间。 当形成化肥熔体时,氨化随后通过具体使用蒸发的氨完成。 本发明也可以是商业生产铵盐的附加物。 本发明生产的肥料含有超过8wt。 %氮,优选15wt。 % 氮。 本发明的目标是针对各个城市废物处理厂的生物固体生产进行定制,以便使物流和责任最小化来保持本发明的肥料制造工厂的效果。
