摘要： A process for the disinfection and aerobic stabilization of concentrated sewage sludge in several steps, using one or more heat-insulated containers, preferably with stirring, with the addition of an oxygen-containing gas, described wherein(a) the sludge coming in, having been concentrated to at least 2% of dry matter, is caused to reach the thermophilic temperature range of >50.degree. C., with pre-heating if required, and then solely by an aerobic degradation without supplying external heat within from 2 to 4 days,(b) the sludge is disinfected by further aerobic degradation without supplying external heat at about 50.degree. C. to 55.degree. C. for at least 20 hours or at >55.degree. C. for at least 10 hours, and(c) the sludge is stabilized to become mesophilic by way of actively cooling it down to about 25.degree. C. to 45.degree. C. and a further aerobic degradation within about 2 to 8 days, and preferably within from 3 to 5 days.

摘要： The sewage lagoon system has a first pond containing mechanically and biologically degrading dissolved and undissolved organic and anorganic pollutant matter, without a recirculation of the forming activated sludge. The first pond is connected to a nitrification lagoon. It contains vertical contact beds for gathering nitrobacteria, which are horizontally flown through. The flow and the introduction of air in the nitrification lagoon are effected by air-water pumps generating a directed flow and provide the transversal flow through the contact beds. The circulation rate in the nitrification lagoon is at least 10 times the throughflow rate.
