Abstract
1. Способ рекультивации карт-накопителей шламохлорлигнина предприятий по производству беленой сульфатной целлюлозы, включающий удаление надшламовой воды и нанесение на поверхность карты-накопителя шлама слоя сыпучего материала, отличающийся тем, что в качестве такого материала используют золу от сжигания углей, нейтрализованную в результате хранения в золоотстойниках до состояния показателя кислотности водной вытяжки золы рН 7.0-8.0, при этом объемное соотношение шлама и золы выбирают в зависимости от состава заполняющего карту отхода в пределах 1:1-2:1, проводят послойное перемешивание указанных материалов и удаление выделившейся в результате их взаимодействия воды с получением золошламлигнинного субстрата.2. Способ по п.1, отличающийся тем, что используют золы углей с общим содержанием AlO>20% и количеством FeOв пределах 5-10%, с содержанием несгоревшего угля >2%.3. Способ по п.1, отличающийся тем, что его применяют для биоремедиации территории.1. A method for the reclamation of slurry chloroglignin storage cards of bleached sulphate pulp production enterprises, including the removal of sludge water and applying a layer of bulk material to the surface of the slurry storage card, characterized in that coal is used as such material, neutralized by storage in ash basins to the state of the acidity index of the aqueous ash extraction, pH 7.0-8.0, while the volume ratio of sludge and ash is selected depending on the composition of the waste filling the card within 1: 1-2: 1, carry out layer-by-layer mixing of these materials and the removal of water released as a result of their interaction with the production of ash-sludge substrate. 2. The method according to claim 1, characterized in that coal ash is used with a total AlO content> 20% and an amount of FeO in the range of 5-10%, with an unburned coal content> 2%. The method according to claim 1, characterized in that it is used for bioremediation of the territory.
