    • 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。

    • The invention can take the form of different suspension systems which provide essentially constant force (zero spring rate) individual wheel support of a vehicle during normal individual wheel travel. Zero spring rate is achieved by supplying essentially constant air pressure to air bag suspension elements. In one system regulation of suspension height and air pressure is achieved by open bottom air bags utilizing the ground effects principle. A second system utilizes closed air bags operating against opposing governing springs. Constant air pressure is supplied from a controlled reservoir. Auxiliary force mechanisms are provided for total system support during high vertical, longitudinal and angular vehicle accelerations.
    • 本发明可以采取不同的悬挂系统的形式,其在正常的单个车轮行驶期间提供车辆基本恒定的力(零弹簧刚度)单个车轮支撑。 通过向气囊悬挂元件提供基本恒定的空气压力来实现零弹簧速率。 在一个系统中,通过使用地面效应原理的开放底部气囊来实现悬挂高度和空气压力的调节。 第二个系统利用相对的调节弹簧操作的封闭气囊。 恒定的空气压力由一个受控储存器供应。 提供辅助力机构用于在高垂直,纵向和角度车辆加速度期间的总系统支持。
