Description
о фильтровывгиот и спекают в печи по обычной технологии.They are filtered and baked in a conventional oven.
При испытании способа в заводских услови х сточные воды, образующиес в процессе разложени катализатора комплекса в производстве этапбензола/ были нейтрализованы известковым молоком . ПРИ этом рН раствора составл ло 7,6-8,5, а температура около . После нейтрализации в раствор ввели 15% окиси алюмини , суспензию перемешали и отфильтровали. Полученный осадок, представл вший собой смесь гидроалюминатов, обжигали во врацанадейс печи при 1420, Полученньгй клинкер содержал 20% СаО-A jO H 80% CaO-iA a A Клинкер измельчали в струйной мельнице до удельной поверхности 4000 . Полученный цемент имел начало схватывани через 5 час и конец - через 6,5 час.When the factory was tested in the process, the wastewater generated during the decomposition of the catalyst of the complex in the production stage of benzene / was neutralized with lime milk. With this, the pH of the solution was 7.6-8.5, and the temperature was about. After neutralization, 15% alumina was introduced into the solution, the suspension was mixed and filtered. The resulting precipitate, which was a mixture of hydroaluminates, was burned in a furnace kiln at 1420. The resulting clinker contained 20% CaO-A jO H 80% CaO-iA a A The clinker was ground in a jet mill to a specific surface 4000. The resulting cement had a start of setting after 5 hours and an end after 6.5 hours.
Результатыиспытани физико-механических свойств полученного цемента в сравнении с в жущим, полученным из смеси после двойной нейтрализации и карбонизации раствора, приведены в таблице:The results of testing the physicomechanical properties of the obtained cement in comparison with the binder obtained from the mixture after double neutralization and carbonization of the solution are shown in the table:

Способ позвол ет получать глиноземистый цемент повышенной чистоты и прочности из отходов про1«11шленности и способствует охране окружакадей среды .The method allows to obtain alumina cement of high purity and strength from waste and contributes to the protection of the environment.
