    摘要： A process for the quiet and smokeless flaring of process gases by sharp separation of the air intake and combustion steps. Compared with conventional off-gas flares, steam consumption is reduced and blow-back of the flame into the mixing tube is avoided by using a combined mixing and combustion chamber. This extends the operating range and life of flare facilities.

    摘要： A process for decomposing organohalogen compounds which are present in dust-laden gases which have a carbon content of less than 0.6% by weight, by oxidative breakdown with the aid of solid catalysts suitable for this purpose, whereina) the dust is deposited from the gases at 250.degree.-500.degree. C., and the dust-free gas is passed together with oxygen or an oxygen-containing gas over the catalyst, orb) the deposition of the dust takes place at below 250.degree. C., the organohalogen compounds are desorbed from the dust in an oxygen-containing gas stream at 250.degree.-500.degree. C., and the gas stream is passed over the catalyst, orc) the dust-laden gas is passed in the presence of oxygen over the catalyst at 250.degree.-500.degree. C., and the dust is subsequently removed.

    摘要： A process for dewatering sewage sludges, the dewatering characteristics of which have been improved by adding an organic flocculant, on a chamber filter press, wherein the greater part of the water in the flocculated sludges is removed by gravity filtration in a process step upstream of the chamber filter press, without application of a pressure difference, and the actual pressure filtration, on the chamber filter press, is only then carried out.In principle, commercial products can be used as the organic flocculant. These are water-soluble, macromolecular compounds which have been obtained by polymerization or copolymerization of acrylamide, acrylic cid and/or their salts, or of esters of acrylic acid or methacrylic acid with specifically modified alcohol components.

    摘要： A process for the biological purification of effluent which is contaminated with nitrogen in the form of ammonium, nitrite or nitrate ions or in the form of organic compounds, by oxidizing the nitrogen under aerobic conditions and reducing the nitrogen under anaerobic conditions, wherein the sewage to be treated, mixed with activated sludge, is subjected, in an aeration basin, to oxygen-containing gas bubbles introduced from below and is thereby simultaneously enriched with dissolved oxygen, to oxidize carbon compounds and nitrogen compounds, and transported upward, by the buoyancy of the gas bubbles, releases gas at the surface of the liquid and, due to the higher average density of the mixture of lower gas content, in part automatically again flows downward in the aeration basin, to undergo further aeration, while in part it overflows into a denitrification basin which communicates with the aeration basin through an opening at the liquid surface, and an opening at the bottom of the partition, is mixed, in the denitrification basin, with the contents thereof by mechanical means and flows back, through an opening near the bottom, in the partition, to the aeration basin.The invention further relates to an activated sludge basin, wherein jet aerators are arranged parallel, and horizontally, at the bottom of the basin, a vertical partition divides the basin into an aeration compartment and a denitrification compartment, both compartments possessing jet aerators, and passages in the partition connect the two compartments of the basin in the area of the surface of the liquid, and in the vicinity of the bottom.
