Abstract

1. Способ переработки осадков сточных вод целлюлозно-бумажного производства, включающий механическое обезвоживание осадка, термообработку концентрата в псевдоожиженном слое катализатора с образованием карбонизированного продукта и промывку его, отличающийся тем, что, с целью повышения адсорбционно-коагуляционных свойств продукта переработки и снижения загрязнения окружающей среды, механическое обезвоживание осадка проводят до содержания сухих веществ 20 - 25%, термообработку концентрата проводят в псевдоожиженном слое алюмомагнийхромового катализатора, организованного решетчатой насадкой, а на выходе из псевдоожиженного слоя катализатора карбонизированный продукт охлаждают до 200 - 300C.2. Способ по п.1, отличающийся тем, что промывку карбонизированного продукта проводят водным раствором неорганической кислоты.1. A method of processing sludge from pulp and paper production, including mechanical sludge dewatering, heat treatment of a concentrate in a fluidized bed of a catalyst with the formation of a carbonated product and washing it, characterized in that in order to improve the adsorption-coagulation properties of the processed product and reduce environmental pollution , mechanical dewatering of sediment is carried out until the content of dry substances is 20–25%, heat treatment of the concentrate is carried out in a fluidized bed of aluminum-magnesium an ohm catalyst, organized by a lattice nozzle, and at the outlet of the fluidized bed of the catalyst, the carbonated product is cooled to 200 - 300C.2. The method according to claim 1, characterized in that the washing of the carbonated product is carried out with an aqueous solution of an inorganic acid.
