    摘要： The invention relates to a method for desulphuration of the digestate and biogas in a digester (1) of urban and/or agricultural and/or industrial effluent, by biochemical and/or thermochemical processes, the digester consisting of an enclosure (2) which is closed at the top, in which anaerobic digestion of a mass of products to be treated making up the digestate (4) takes place, the digester comprising at least one loop (10) for external recirculation of the digestate; an oxidant is injected at least at one point (13, 14) of the loop (10), the injection conditions being as follows: the speed of circulation of the digestate in the loop (10) must be high enough to prevent the deposition of sulphur on the walls of the pipes; the contact time between the injected oxidant and the recirculated digestate recirculated from the injection point (13, 14) of the oxidant until the reinjection point (11b) of the digestate must be long enough for all the oxidant to be dissolved in the liquid phase of the digestate; the amount of oxygen in the oxidant injected into the recirculation loop must be low enough to avoid the presence of oxygen in the biogas, but high enough to eliminate the hydrogen sulphide from the biogas.

    摘要： A method for the treatment of activated slurries of waste water, notably of urban waste water, characterized in that the water to be treated, previously subjected to the standard prior treatments such as screening, renewal of sediments, degreasing, and possibly a primary decantation, is directed to a single ventilation or aeration basin with a high mass load where it dwells during a reduced period, from which it is discharged to a clarifier-thickener equipped with inclined parallel plates or tubes, stimulating the separation of the slurry, which is being recycled in the ventilation or aeration basin at a high concentration made necessary by the reduced dwelling time of the water in the basin.

    摘要： An apparatus for the anaerobic treatment of waste water, including in a same closed enclosure, under a gas pressure, a fermentation zone and a decantation zone, with internal recycling of the slurries from the decantation zone to the fermentation zone, made of at least two attached identical cells in mutual communication. The two cells operate alternately and reciprocally as a fermentation cell and as a decantation cell. Each cell is fitted out, in order to be fed while it operates as a decantation cell, with a gas-lift transfer device with two branches, one of the branches opening into the cell which is attached to that where it is placed.
