    • The invention relates to a process for the production of polyurethane(urea) compositions which contain lignite and/or peat bound in an abrasion-proof manner, which are preferably modified cationically and which have a very high water absorbability. The compositions are produced by reacting isocyanate-terminated prepolymers, which are preferably cationically modified, and which preferably have a functionality of more than 2.1, with more than the stoichiometric quantity of water in the presence of lignite and/or peat and optionally in the presence of organic and/or inorganic fillers and biomasses (living cells, living bacteria or enzymes). The corresponding polyurethane(urea) compositions contain up to 95% by weight of lignite and/or peat in the filler-containing polyurethane(urea) composition and are already swollen from production. The water absorbability (WAF) value thereof when suspended in water is from 33 to 97% by weight of water.The compositions can be used, in a form optionally containing biomasses incorporated therein, as carriers in microbial synthesis processes for the production of complicated organic compounds, or as carriers for the growth of plants.
    • 本发明涉及一种生产聚氨酯(尿素)组合物的方法,该组合物含有以耐磨损方式结合的褐煤和/或泥煤,其优选是阳离子改性且具有非常高的吸水性。 组合物通过异氰酸酯封端的预聚物(其优选阳离子改性,优选具有大于2.1的官能度)与在褐煤和/或泥炭存在下具有超过化学计算量的水反应而产生,并且任选地存在 的有机和/或无机填料和生物质(活细胞,活细菌或酶)。 相应的聚氨酯(尿素)组合物在含填料的聚氨酯(脲)组合物中含有高达95重量%的褐煤和/或泥炭,并且已经从生产中膨胀。 悬浮在水中时的吸水率(WAF)值为33〜97重量%。 组合物可以任选地含有其中并入的生物质的形式用作用于生产复杂有机化合物的微生物合成方法中的载体,或用作植物生长的载体。

    • The present invention relates to the use of non-floating, non-abrasive, highly-filled polyurethane (urea) compositions of high water-absorbability, which during their production contain no cells capable of growth as carriers for biomasses in the biological treatment of waste-containing liquids. These carriers have a filler content of greater than 15% by weight and less than 95% by weight (based on the moisture-free weight of the filler-containing polyurethanes). The fillers are selected from the group consisting of natural materials containing finely-divided fossil lignocelluloses or the secondary products thereof (e.g., peat, lignite, mineral coal or coke), active carbon, finely-divided distillation residues, inorganic fillers, homogeneous or cellular plastics particles (and more particularly polyurethane foam (waste) particles) and mixtures thereof. The polyurethane (urea) is a hydrophilic and/or hydrophobic polyurethane(urea), and preferably contains cationic groups. These highly-filled, polyurethane (urea) carriers have a water-absorbability exceeding 33% by weight of water in the swollen carrier.These carriers allow improved treatment of industrial and municipal liquid waste to be achieved in biologically-operating treatment plants. Treated waste which has reduced toxicity, a diminished smell, improved clarity and a very small residual content of organic, decomposable material is obtained due to the increased decomposition effect thereof.
    • 本发明涉及使用具有高吸水性的非浮动,非研磨,高填充的聚氨酯(尿素)组合物,其在生产过程中不含能够生长的细胞作为废物生物处理中生物质的载体 含液体。 这些载体的填料含量大于15重量%且小于95重量%(基于含填料的聚氨酯的无水重量)。 填料选自含有细碎化石油木质纤维素的天然材料或其二次产物(例如,泥煤,褐煤,矿物煤或焦炭),活性炭,精细分馏的蒸馏残余物,无机填料,均相或细胞 塑料颗粒(尤其是聚氨酯泡沫(废物)颗粒)及其混合物。 聚氨酯(尿素)是亲水和/或疏水性聚氨酯(尿素),优选含有阳离子基团。 这些高填充性聚氨酯(尿素)载体在溶胀载体中的吸水率超过33重量%。 这些载体允许在生物操作的处理设备中实现工业和城市废液的改进处理。 由于其分解效果的增加,得到了具有降低的毒性,减少的气味,改善的澄清度和非常小的有机可分解材料残留量的废弃物。
