Description
3 Известь подготавливают в виде известковой суспензии 10%-ной концентрации, после чего смешивают с активным илом. Уплотнение скоагулированного ила в илоуплотнител х провод т в течение 3 час. Сливную воду из илоуплотнителей возвращают в начало очистных сооружений, а уплотненный активный ил обезвоживают на фильтр-прессах до влажности 65%. 4 Предмет изобретени Способ обработки осадков сточных вод из вестью с последующим уплотнением и механическим обезвоживанием, отличающий-, с тем, что, с целью обезвоживани активного ила, последний обрабатывают известью в количестве 50-350% от веса сухого ила. 3 Lime is prepared in the form of a lime suspension of 10% concentration, and then mixed with active sludge. Consolidation of coagulated sludge in sludge compactors is carried out for 3 hours. The drainage water from the sludge packers is returned to the start of the treatment plant, and the compacted activated sludge is dewatered on filter presses to a moisture content of 65%. 4 Subject of the invention. A method for treating sewage sludge from a tide followed by compaction and mechanical dewatering, which is such that, in order to dehydrate activated sludge, the latter is treated with lime in an amount of 50-350% by weight of dry sludge.
