Description

Przedmiotem wynalazku jest zbiornik do mie¬ szania i napowietrzania scieków przeznaczony do biologicznego oczyszczania scieków za pomoca" o- sadu czynnego.Znany jest zbiornik do mieszania i napowietrza¬ nia scieków z polskiego opisu patentowego nr 97 484. Zbiornik w przekroju pionowym posiada ksztalt prostokata lub trapezu. Wewnatrz zbior¬ nika umieszczone sa w jego osi glównej aeratory turbinowe zas miedzy aeratorami wstawione sa scianki na calej glebokosci zbiornika. W ten spo¬ sób zbiornik podzielono funkcyjnie przegroda na dwa polaczone koryta o jednakowym przekroju.Przeplyw cieczy w kazdym korycie wywolany jest przez czesc wirnika aeratora, który wytwa¬ rzajac turbulencje poziomo-pionowa stwarza naj¬ lepsze warunki hydrauliczne w calym ukladzie zbiornika. W obu korytach zbiornika wstawione sa szczotki napowietrzajace lub rotory mamucie o kierunku obrotów zgodnym z kierunkiem prze¬ plywu cieczy nadanym przez aeratory turbinowe.Scieki surowe doprowadzone z zakladu mieszaja sie w korycie doplywowym ze zregenerowanym powrotnym osadem czynnym i wprowadzone sa do zbiornika w jego srodkowej czesci w poblizu szczotki lub rotora przy dnie prostopadle do stru¬ gi przeplywajacej cieczy w zbiorniku.Celem wynalazku jest uzyskanie najwyzszej sprawnosci procesu oczyszczania scieków, w któ- s - 10 & 25 30 2 rym osad czynny bylby zawsze w stanie zawie¬ szonym i byl równomiernie rozprowadzany wraz z wlasciwa iloscia tlenu w kazdej czesci zbiornika niezaleznie od jego objetosci.Istota wynalazku jest zbiornik do mieszania i napowietrzania scieków podzielony sciankami na koryta w ten sposób, ze oczyszczana ciecz prze¬ plywa w obiegu zamknietym.W sciankach dzielacych zbiornik na koryta, na koncach tych scianek lub w miejscach ich lacze¬ nia zainstalowane sa aeratory turbinowe. Scian¬ ki te na calej swej dlugosci posiadaja wysokosc równa lub wyzsza od wysokosci przeplywajacej strugi oczyszczanej cieczy, natomiast w miejscach zainstalowanych aeratorów turbinowych posiadaja wyciecia w glab poziomu cieczy^ Przedmiot wynalazku jest przedstawiony na przykladzie wykonania na rysunku, w którym fig. 1 przedstawia zbiornik do mieszania i napowie¬ trzania scieków w widoku z góry, natomiast fig. 2 przedstawia ten zbiornik w przekroju wedlug o- znaczen A—A na fig. 1. Zbiornik stanowi komore w ksztalcie prostokata. Wewnatrz zbiornika 1 wstawione sa scianki 2 dzielace ten zbiornik na kopyta 3. W miejscach laczenia scianek lub na ich koncach zainstalowane sa aeratory turbinowe 4. W miejscach zainstalowania aeratorów sa wy¬ ciecia 5 do ukierunkowywania przeplywu strugi cieczy. 111 504lii 504 Zastrzezenie patentowe Zbiornik do mieszania i napowietrzania scie¬ ków z zainstalowanymi na osi glównej aeratora- mi turbinowymi i umieszczonymi pomiedzy nimi na calej glebokosci zbiornika sciankami wzdluz¬ nymi dzielacymi zbiornik na dwa polaczone ko¬ ryta, w których ustawione sa szczotki napowie¬ trzajace i/lub rotory mamucie wedlug patentu nr 97 484, znamienny tym, ze w sciankach (2) dzie¬ lacych zbiornik (1) na koryta (3) lub w miejscach laczenia scianek wykonane sa wyciecia (5) w glab poziomu cieczy, w których umieszczone sa aera- tory turbinowe (4).Fig. 7 FIG. 2.A-A J 5 / r/ / 7y~<~r/w '/? / U DN-3, zam. 347/81 Cena 45 zl PLThe subject of the invention is a tank for mixing and aerating sewage, intended for biological treatment of sewage by means of "active sediment." There is a well-known container for mixing and aerating sewage from the Polish patent specification No. 97,484. The tank in its vertical section has the shape of a rectangle or Inside the reservoir, on its main axis, turbine aerators are placed, and between the aerators, walls are inserted along the entire depth of the reservoir. Thus, the reservoir is functionally divided into two interconnected troughs of the same cross-section. The liquid flow in each channel is caused by part of the rotor of the aerator, which creates the best hydraulic conditions in the entire system of the reservoir by creating horizontal and vertical turbulence. In both channels of the reservoir there are airing brushes or mammoth rotors with the direction of rotation in the direction of liquid flow given by the turbine aerators. raw brought from the plant mix into bark The inflow life with regenerated active sludge and are introduced into the tank in its central part near the brush or rotor at the bottom perpendicular to the stream of flowing liquid in the tank. The aim of the invention is to obtain the highest efficiency of the sewage treatment process, in which - 10 & The active sludge would always be in a suspended state and would be evenly distributed with the correct amount of oxygen in every part of the tank, regardless of its volume. The essence of the invention is a tank for mixing and aeration of sewage, divided by walls into channels in such a way that the liquid flows in a closed circuit. In the walls dividing the tank into the troughs, turbine aerators are installed at the ends of these walls or in the places where they connect. These walls, along their entire length, have a height equal to or greater than the height of the flowing stream of the treated liquid, while in places of installed turbine aerators they have cuts in the depth of the liquid level. for mixing and aerating wastewater in top view, while FIG. 2 shows the vessel in section according to the reference A-A in FIG. 1. The vessel is a rectangular chamber. Inside the tank 1, walls 2 are inserted, dividing the tank into hooves 3. Turbine aerators 4 are installed at the points where the walls are joined or at their ends. In the places where the aerators are installed, there are cutouts 5 for directing the flow of the liquid stream. 111 504lii 504 Patent claim A tank for mixing and aerating wastewater with turbine aerators installed on the main axis and placed between them along the entire depth of the tank with longitudinal walls dividing the tank into two interconnected chutes, in which the aeration brushes are placed rocking and / or mammoth rotors according to patent No. 97 484, characterized in that in the walls (2) of the reservoir (1) on the troughs (3) or at the places where the walls are joined, cuts (5) are made at the depth of the liquid which are located turbine aerators (4). 7 FIG. 2.A-A J 5 / r / / 7y ~ <~ r / w '/? / U DN-3, order 347/81 Price PLN 45 PL
