Method and device for purifying wastewaters

   
   

The invention relates to a method for purifying wastewaters, particularly wastewaters produced in the paper industry, involving the following steps: a) aerobic clarification of the wastewater using activated sludge in an activation stage; b) carrying out, in a secondary settling tank, a subsequent clarification of a portion of the wastewater/activated sludge mixture leaving the activation stage; c) desiccating, in a desiccation unit, another portion of the wastewater/activated sludge mixture leaving the activation stage; d) returning at least a portion of the activated sludge removed in steps b) and c) into the activated sludge tank.

Вымысел относит к методу для очищать отработанные воды, определенно отработанные воды произведенные в бумажной промышленности, включая following шаги: a) аэробное пояснение отработанной воды использующ активированную шугу в этапе активации; б) нося из, в вторичный устанавливая бак, затем пояснение части смеси шуги wastewater/activated покидая этап активации; ч) desiccating, в блоке высушивания, другая часть смеси шуги wastewater/activated покидая этап активации; д) возвращающ по крайней мере часть активированной шуги, котор извлекли в шагах б) и ч) в активированный бак шуги.
