    摘要: 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.

    摘要: The present invention relates to a process for the improved separation of clarified liquids from biomass or rather for the separation of clarified sludges in the (aerobic and/or anaerobic) biological treatment of sewage using magnetically separable materials as carrier masses. The carrier masses are organic materials containing magnetically separable inorganic materials incorporated in abrasion-resistant form. These magnetically separable carriers occupy a suspension volume of from 1 to 85% by volume, based on the clarified liquid.The carriers contain magnetically separable inorganic materials incorporated as fillers in organic polymeric materials, particularly in cellular polymeric carriers. Other organic or inorganic fillers may also be used in these organic carriers. The magnetically separable materials used are oxides or mixed oxides of heavy metals, preferably iron oxides, such as Fe.sub.3 O.sub.4 (magnetite) and .gamma.-Fe.sub.2 O.sub.3, which are used in average particle sizes of less than 50 .mu.m, preferably less than 10 .mu.m and more preferably less than 3 .mu.m, for example from 0.1 to 1 .mu.m.These magnetic carriers provide for magnetic separation of the biomasses containing these magnetic materials in the biological treatment of sewage.

    摘要: 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.

    摘要: This invention relates to a process for the production of optionally cellular polyurethane plastics using a reactive filler obtained by finely grinding a distillation residue of the type accumulating in the commercial production of tolylene diisocyanate. It is possible in this way to recycle the previously unuseable slag-like residues and at the same time to improve the mechanical properties of the polyurethane plastics filled with them.
