- W4288703692 abstract "У статті наведено опис компактних споруд глибокої очистки стічних вод підприємств харчової промисловості. Для очистки стічних вод запропоновано застосовувати виготовлені з металу відстійники-флотатори, комбіновані з аеротенками-відстійниками першого ступеню, а також аеротенки-відстійники другого ступеню, комбіновані з фільтрами з плаваючим завантаженням, що монтуються безпосередньо на майданчику очисних споруд.
 
 The article presents the compact facilities for food industry small enterprises deep wastewater treatment, what were designed in the sectoral wastewater treatment plant laboratory at the food industry enterprises. For a preliminary removal from wastewater suspended solids and fats proposed a new combined structure - settler-flotator. Settler-flotator is a vertical type flotation cell in which wastewater is first exposed to short-term sedimentation then pressure flotation with recirculation. This allows: - increase the overall efficiency of suspension removal from wastewater by the preliminary sedimentation the largest poorly flotating particles; - provide the most effective contact solids and air bubbles during their joint vertical movement; - to simplify the process of removing sludge and sediment. For biological wastewater treatment of food industry proposed to use aeration tanks of large hydraulic height (8-10 m) with the surface jet aeration, combined with peripheral secondary settling tanks. Their application provides the following advantages: 1) in one construction will be biological wastewater treatment at high doses of activated sludge and its effective separation from treated wastewater; 2) the use of jet aeration system provide high oxidizing ability and efficiency of aeration; 3) due to the continuous sampling a sludge mixture from the bottom and feed on the surface jet aerators, sludge recirculation will be provided and downward movement sludge mixture in the aeration zone; 4) in the bottom of the aeration zone due to the gradual reduction of dissolved oxygen in biological processes formed anoxid zone, which provides the ability to simultaneous nitrification-denitrification. Final stage of wastewater treatment is held in filters with floating filling of expanded polystyrene. Metal wastewater treatment edifices supposed to be mounted above ground level." @default.
