    摘要: A process for the utilisation of solid paper mill waste comprises introducing earthworms and/or earthworm cocoons into a mass of the waste and allowing the worms to mature and breed in the waste until it is converted into a friable, soil-like material. The earthworms and the friable, soil-like material may be subsequently separated; the material is suitable for use as a horticultural compost.

(Figure 1).

    摘要: The invention relates to a process for treating bleaching liquors from pulping processes based on organic acids. The process is characterized in that inorganic acid, such as nitric acid, phosphoric acid and/or sulphuric acid, is added into a bleaching liquor obtained from the bleaching or a stage closely associated with bleaching, whereby organic acids contained in the bleaching liquor are released into the bleaching liquor. The organic acids are then separated from the bleaching liquor and recycled to the cooking stage to be used as cooking chemicals. The nitrogen-, phosphor- and/or sulphur-containing product thereby produced, from which organic acids have been separated, is recovered to be used as a fertilizer or as raw material for a fertilizer.

    摘要: The present invention relates to a method for producing a soil improvment material. According to the invention such a material is produced by the steps of mixing wood fiber slurries from paper mills and fly ash from fossil fuel power and heating plants and of further treating the material to obtain a packetable product. The wood fiber slurry is treated to become an almost gruel-like slurry and is pressed through a sieve belt press (4) to become considerably dewatered, down to a water content of about 20 %, after which the slurry is pre-mixed with fly ash, after which the main mixing is carried out to obtain homogenous lump-like particles, which are subjected to a size reduction process through screening or the product after the main mixing and a possible size reduction process is pelletized. The invention also relates to an apparatus (1) designed to carry out the method as well as a soil improvement material obtained according to the method and by means of the apparatus respectively.

    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 "NPK" 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.
