摘要： An improved process for enhancing the plant nutrient value of relatively low analysis organic waste material (e.g., sewage sludge) involves treating the waste material with an acid and base in a pipe-cross reactor. The process more particularly involves mixing the waste material with water to form a slurry (or initially taking the waste material as a slurry); pumping the slurry to a pipe-cross reactor for reaction with a base, acid, and water to form a melt; spraying the melt onto a recycling bed of fines in a granulator, and flashing off the water contained in the melt as steam; rolling the melt onto recycled fine particles in a granulator to form granulated particles; and drying these granulated particles to form an enhanced plant nutrient value composition (e.g., a fertilizer or soil conditioner having a greater nullNPKnull value than the original relatively low analysis organic waste material). The invention also includes fertilizers produced according to the improved process, which fertilizers are of the same size and shape and density of commonly used fertilizers. The method advantageously utilizes the heat generated by the exothermic acid-base reaction in the pipe-cross reactor to remove the approximately 80% water from sludge, thus saving large amounts of energy normally used in conventional drying or burning methods, while, at the same time, conserving the intrinsic values of the nutrients and humates contained in the sludge. In one embodiment, the process includes a method of disposing of spent acid from a hot dip galvanizing process or a steel pickling process involving incorporating the spent acid to maintain the low pH of a venturi scrubber used in the improved process.
摘要翻译：用于提高相对低分析的有机废物（例如，污水污泥）的植物营养价值的改进方法包括在管交叉反应器中用酸和碱处理废料。该方法更具体地涉及将废料与水混合以形成浆料（或者最初以废料作为浆料）; 将浆料泵送到管交叉反应器中以与碱，酸和水反应以形成熔体; 在造粒机中将熔体喷射到细粒的再循环床上，并将蒸汽中包含在熔体中的水闪烁; 在造粒机中将熔体滚动到再循环的细颗粒上以形成造粒颗粒; 并干燥这些造粒颗粒以形成增强的植物营养价值组合物（例如，具有比原始相对较低分析的有机废物材料更大的“NPK”值的肥料或土壤调理剂）。本发明还包括根据改进方法生产的肥料，其中肥料具有与常用肥料相同的尺寸，形状和密度。该方法有利地利用了在交叉反应器中由放热酸碱反应产生的热量从污泥中除去约80％的水，从而节省了常规干燥或燃烧方法中通常使用的大量能量，同时时间，保持污泥中所含营养物和腐殖酸的内在价值。在一个实施方案中，该方法包括从热浸镀锌工艺或钢酸洗工艺处理废酸的方法，包括掺入废酸以维持改进方法中使用的文丘里洗涤器的低pH。

摘要： A controlled release product is provided having a suppressed initial release period and a predetermined longevity. The product includes a particulate water soluble core material and a semi-permeable coating layer applied on the core material for controlling the release rate of the core material. The semi-permeable coating layer is formulated in accordance with the following equation to provide a release rate wherein initial release of core material from the product is suppressed so that less than about 15 weight percent of core material is released from the product within a 24 hour period after application of the product and wherein longevity of release, at ambient temperature, between the time of application and the time at which at least about 75 weight percent of the core material is released from the product is 60 days or less: 1 WVTR = null null null null null null null d 2 wherein: (i) WVTR is the water vapor transmission rate of the semi-permeable coating expressed in gramsnullnullm/meters2nullday; (ii)null is the water diffusion rate (water flux) through the semi-permeable coating expressed in grams/day; (iii) null is the thickness of the coating layer expressed in nullm; and (iv) d is the average diameter of the particulate core material expressed in meters.

摘要： In a dry or concentrated liquid fertilizer when local water is added to dilute to a working concentration, the hardness components (e.g., Ca/Mg) in the local water react with the fertilizer components and begin to form low-solubility salts. These low-solubility salts form sludges in the working mixture and begin to scale up in the feeding tubes through which the liquid fertilizer is pumped. Furthermore, the fertilizer is deprived of the nutrient values of these low-solubility salts and, as a result, the economic value of the fertilizer is reduced. By adding excess sequestering agent(s) (i.e. above the amounts needed to dissolve the nutrients in the original fertilizer formulation) precipitation of the hardening components of the local water in the mixing tank, in the feeding tubes, and in the growing media is avoided, and previous scaling can be remedied.
摘要翻译：当加入局部水以稀释至工作浓度时，在干燥或浓缩的液体肥料中，局部水中的硬度成分（例如Ca / Mg）与肥料组分反应并开始形成低溶解度盐。这些低溶解度盐在工作混合物中形成污泥，并开始在供给液体肥料泵送的进料管中放大。此外，肥料被剥夺了这些低溶解度盐的营养价值，结果减少了肥料的经济价值。通过添加过量的螯合剂（即高于在原始肥料配方中溶解营养物所需的量），避免了混合罐，进料管和生长介质中局部水的硬化成分的沉淀，并且可以补救以前的缩放。
