摘要： A process for decontaminating a solid material contaminated with an organic pollutant wherein the solid material contains grains with a particle size of up to 60 microns, which includes the steps of: (a) extracting the organic pollutant from the solid material containing grains with the particle size up to 60 microns by using a microemulsion which includes a thermodynamically stable, macroscopically homogeneous and optically transparent mixture of water, an apolar hydrophobic solvent, and a surfactant to form a cleaned solid material and a pollutant-containing microemulsion; (b) separating the cleaned solid material from the pollutant-containing microemulsion; and (c) splitting the pollutant-containing microemulsion into a surfactant-rich phase and a pollutant-containing phase.

摘要： Aerobic purification of waste water with intermittent batchwise supply of waste water to the activated sludge tank from which the treated waste water drains continuously is disclosed, in which the nitrate content in the waste water is simultaneously reduced by throttling the aeration of the activated sludge tank, starting with the admission of the waste water to the tank, to values equivalent to less than or equal to 0.5 mg/l dissolved oxygen. In particular, aeration may be off until such time as the nitrate content in the tank has dropped below 5 mg/l, in particular below 1 mg/l. In the case of urban waste waters a cycle time of about 1 hour is expediently employed under these circumstances and the aeration is shut off for about 5 minutes, starting from the rapid admission of the waste water charge. Preferably, inlet charges are less than or equal to 30%, in particular between about 5% and 20%, of the tank capacity. In this procedure, nitrate present is degraded in the phase involving oxygen throttling, while in the subsequent phase (over longer times) ammonium fed in with the waste water supplied is converted into nitrate, provision being made for a sufficient population of nitrifying bacteria in the tank.
摘要翻译：公开了对经过处理的废水连续排出的活性污泥槽间歇地间歇地供给废水的废水的有氧净化，其中通过节流活性污泥槽的通风同时降低废水中的硝酸盐含量，从废水进入罐开始，达到相当于0.5mg / l溶解氧的值。特别是，曝气可能会停止，直到罐中的硝酸盐含量降至5 mg / l以下，特别是低于1 mg / l。在城市废水的情况下，在这种情况下方便地使用约1小时的循环时间，并且从快速进入废水装置开始，通风关闭约5分钟。优选地，入口电荷小于或等于罐容量的30％，特别是约5％至20％。在该方法中，存在的硝酸盐在涉及氧气节流的阶段中降解，而在随后的阶段（更长时间）中，供给的废水中的铵转化为硝酸盐，为了足够的硝化细菌群体提供坦克。

摘要： The coalescence and release of bubbles from packing that supports the growth of microorganisms is promoted by mechanical action on the packed bed arrangement, in particular by continuous or intermittent vibrations, rotations, or by rocking motions. With particular advantage, a reactor vessel which is typically tubular is filled with packing upon which microbial growth is sustained, preferably leaving a free space of 10% to 35%, in particular 15% to 20%. The reactor vessel has an axis that is substantially horizontal but preferably inclined by at least about 3.degree., and is set continuously or intermittently, for example, by an axle drive or by means of friction wheel drive, into rotational or rocking motions about that axis. The gas can be discharged, for example, via valves and a cam mechanism. Alternatively, a vent pipe, taken through the hollow shaft on the discharge side and upwards, can be provided behind a screen plate. Pipes that are parallel to the axis and that have openings, which are protected by finlike rims with slots, feed liquid or gas to the biomass-containing system in the reaction vessel. In another embodiment, a vertical reactor is equipped with packing provided on vibrating plates which are set into vibration, preferably intermittently. For denitrification, a nitrate-nitrite degradation stage can be provided upstream of the reactor vessel.
