Description

Die Erfindung betrifft ein Verfahren zur Sperrenbildung von hinter Biofiltern ausgetragenen Bakterien, Pilzen, Sporen usw.The invention relates to a method for locking formation of bacteria, fungi discharged behind biofilters, Spores etc.

Es ist bekannt, daß längere Zeit in Betrieb befindliche Biofilter u. U. Pilzsporen und Bakterien freisetzen. Der AT-PS 3 54 995 ist ein Verfahren zur Sporenbildung von hinter Filtern ausgetragenen Bakterien entnehmbar, bei dem ein Filter mit einer Quarzfüllung eingesetzt wird. Zur wirksamen Sperrenbildung muß das Bakterien enthaltende Fluid allerdings vor Durchgang durch die Quarzfüllung er­ wärmt und anschließend wieder abgekühlt werden. Dies er­ fordert einen hohen apparativen Aufwand. Es ist daher Aufgabe der Erfindung, ein gattungsgemäßes Verfahren anzugeben, bei dem die Bakterien und Pilzsporen ohne hohen apparativen Auf­ wand wirksam zurückgehalten werden. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.It is known that it has been in operation for a long time Biofilter u. U. release fungal spores and bacteria. The AT-PS 3 54 995 is a process for the formation of spores Bacteria discharged behind filters can be removed a filter with a quartz filling is used. For effective barrier formation, the bacteria-containing must Fluid, however, before it passes through the quartz filling warms and then cooled again. This he requires a lot of equipment. It is therefore a task the invention to provide a generic method in which the bacteria and fungal spores without high apparatus wall can be effectively withheld. This task is accomplished by the characterizing features of claim 1 solved.

Erfindungsgemäß wird vorgeschlagen, hinter den Biofilter­ massen ein in einzelnen Lagen geschichtetes Chemisorptions­ massenfilter einzusetzen. According to the invention, it is proposed behind the biofilter mass a chemisorption layered in individual layers insert mass filter.  

Diese Chemisorptionsmassenlagen werden erfindungsgemäß mit stark alkalischen Massen pH ca. 12,8 und stark sauren Mas­ sen pH 0,5-1,0 wechselweise eingesetzt.According to the invention, these chemisorption mass layers are included strongly alkaline masses pH approx. 12.8 and strongly acidic mas pH 0.5-1.0 alternately used.

Vorzugsweise werden folgende Massen verwendet:
Als Trägermaterial wird ein Steinkohlenkoks der Sorten Brechkoks IV bis Brechkoks III eingesetzt, die mit Na­ tronlauge-, Kalium- oder Natriumcarbonat-, Natronkalk­ lösung getränkt und als alkalische Masse pH ca. 12,8 eingesetzt werden.The following masses are preferably used:
A hard coal coke of the types Brechkoks IV to Brechkoks III is used as the carrier material, soaked in sodium hydroxide, potassium or sodium carbonate, soda lime solution and used as an alkaline mass pH approx. 12.8.

Für die Herstellung saurer Massen pH 0,5-1,0 werden als Tränkflüssigkeit saure FeII/FeIII-Salze mit Schwe­ felsäure auf den pH-Wert von 0,5-1,0 gebracht, ein­ gesetzt. Als neutrale Austrittsschicht wird eine reine Koksfüllung der obengenannten Brechkokssorten geschal­ tet.For the production of acidic masses pH 0.5-1.0 acidic FeII / FeIII salts with Schwe brought to pH 0.5-1.0 set. The neutral exit layer becomes a pure one Coke filling of the above-mentioned types of crushed coke tet.

Es wurde gefunden, daß die Wechselwirkung des dem Bio­ filter nachgeschalteten Chemisorptionsfilter mit der Wechselwirkung von stark alkalischen und stark sauren Massen die Bakterien und Pilzsporen tötet, die von den Schüttmassen zurückgehalten werden. The interaction of the bio filter downstream chemisorption filter with the Interaction of strongly alkaline and strongly acidic Masses kills the bacteria and fungal spores by the Bulk materials are retained.  

Nach Erschöpfung des Filters kann der Koks als zusätz­ licher Brennstoff einer Müllverbrennungsanlage zuge­ führt werden.After the filter is exhausted, the coke can be used as an additional Liche fuel a waste incineration plant leads.
