Method for recovering a disposal trench with a biomat slime, and method for operating a waste treatment vessel

   
   

A soil-based disposal trench that has failed from a biomat slime is recovered by adding a facultative anaerobic bacteria to an effluent that flows into the disposal trench. The facultative anaerobic bacteria consumes the biomat slime and, in one embodiment, supplants a strictly aerobic bacteria in the soil that converts nitrites to nitrates. As a result, the facultative anaerobic bacteria interrupt the conventional process of nitrification, changing the nitrites to nitrogen gas.

Uma trincheira solo-baseada da eliminação que falhe de um slime do biomat é recuperada adicionando as bactérias anaerobic facultative a um effluent que flua na trincheira da eliminação. As bactérias anaerobic facultative consomem o slime do biomat e, em uma incorporação, suplantam as bactérias estritamente aerobic no solo que converte nitrites aos nitrates. Em conseqüência, as bactérias anaerobic facultative interrompem o processo convencional do nitrification, mudando os nitrites ao gás do nitrogênio.
