Description

(54) СПОСОБ БИОЛОГИЧЕСКОЙ ОЧИСТКИ СТОЧНЫХ ВОД(54) METHOD OF BIOLOGICAL WASTEWATER TREATMENT

в аэротенк. В завиотмости от состава сточных вод обработку иловой смеси в пенных сепаратора педует проводить в две-три ступени. Возврат активного ила большей :онценграции к повышедае его активносш поаче пешак сепараторов сокращает объем аэро шнков.in the aeration tank. Depending on the composition of the wastewater, the treatment of the sludge mixture in the foam separator is carried out in two or three stages. The return of activated sludge to a larger one: its concentration on the rise of its activity in a peshaku separator reduces the volume of aero-fillers.

Иловую . с конценграцкен 0,2-0,3 г/л после конечнот ступени сепараторов направл ют дл  осветлени  во вторичные отсгой1ики. Оюсоб неSilt. With a concentration of 0.2-0.3 g / l after the end of the stage, the separators are sent for clarification to secondary waste. Oyusob not

требует дл  отделени  активного ила установки напорных резервуаров и высоконапорных насосов. Сокращение времени обработки в пенньк сепараторах дг« 6-10 мин уменьшает объем сооружений.requires for separating activated sludge installation of pressure tanks and high-pressure pumps. Reducing the processing time in foam separators dg 6-10 min reduces the volume of facilities.

Степень очистки 94,5-95,5 %; остаточна  концентраци  по БПКз (биологическое потреб}1ение кислорода) 10-15 мг/л.The degree of purification 94,5-95,5%; residual concentration according to BPCK (biological oxygen demand) is 10-15 mg / l.

Сравнительные даннью по очистке сточных вод предлагаемым способом и известным приведены в таблицу.Comparative data on wastewater treatment by the proposed method and known are given in the table.
