PROCEDURE FOR DECONTAMINATION OF LIQUID RESIDUAL HIGH ORGANIC AND NITROGEN LIQUID.

摘要

Procedure for decontamination ofliquid residuals of high organic and nitrogen load.;The present invention relates to aprocedure for the decontamination of liquid residuals ofhigh organic and nitrogen load, which includes the followingstages:;a) roughing of solids,;b) fermentationanoxic-aerobic-anoxic,;c) decantation of the effluent from theanoxic-aerobic-anoxic fermentation from stage b) above, obtaining an effluent consisting ofa sedimented sludge and a liquid fraction and;d) anaerobic digestion of sedimented sludge andof the supernatant of that of step c) above, obtainingbiogas, and an effluent consisting of a digested sludge and adigested liquid fraction,;optionally a homogenization stage beforeof fermentation,;and its use in organic and nitrogen purificationof a spill, in which the following by-products are producedrecyclable: biological sludge, liquid effluent, electrical energy andheat energy
