摘要
"BIOLOGICAL TREATMENT PROCESS FOR EFFLUENTS CARRIED FROM URBAN OR INDUSTRIAL IMPURSES AND INSTALLATION FOR THE IMPLEMENTATION OF THE PROCESS". Process for the biological treatment of effluent-laden effluents of urban or industrial origin, characterized by the fact that it employs a single high-mass aeration basin (1) in which the raw or mechanically pre-treated effluent is mixed without prior decanting with a free activated sludge-like microbial culture evolving in a low aerated environment of the order of 0,1 to 0,2 kg O ~ 2 ~ / kg DB05 eliminated, the applied organic load being equal to or exceeding 2 kg DCO / kg MS.d, preferably 4 kg DCO / kg MS.d or more, the hydraulic residence time of the raw effluent within the single aeration basin being between 30 and 90 minutes, preferably between 40 and 60.
