  • Treatment Of Sludge (AREA)

Description

ботанного шлаком, больше, чем ила без добавок 1 с добавкой смеси окислов.slag, more than silt without additives 1 with the addition of a mixture of oxides.

Дл  определени  влажности отсто вшегос  ила в делительные воронки наливают 100 мл смеси жидкости с активным илом без добавок и с добавкой шлака и смеси окислов, иеремешивают и через 10, 30, 60 мин и 3, 8 ч сливают уплотиенный ил, определ ют его влажность. Результаты эксиериментальных данных по влажности приведеиы в таблице.To determine the moisture content of settled sludge, 100 ml of a mixture of liquid with activated sludge without additives and with the addition of slag and a mixture of oxides are poured into separating funnels, mixed, and after 10, 30, 60 minutes and 3, 8 hours condensed sludge is discharged, its humidity is determined. The results of experimental data on humidity are given in the table.

Из таблицы видно, что введение в активиый ил шлака более эффективно, чем смеси окислов.The table shows that the introduction of slag into activated sludge is more efficient than the mixture of oxides.

Использование шлаков в качестве добавки ио предлагаемому способу в технологическом процессе очистки воды позволит увеличить рабочую нагрузку илоунлотиител  в 20 раз, врем  обработки сокрашаетс  до 10 мин; при этом влажность ила понижаетс  с 99,8 до 97,5%.The use of slags as an additive to the proposed method in the process of water purification will increase the workload of the separator by 20 times, the treatment time is shortened to 10 minutes; while the moisture content of the sludge decreases from 99.8% to 97.5%.
