    • The invention relates to a method and device for the continuous filtration of liquids containing solid matter, in particular for cleaning wastewater, by means of a filter bed consisting of a particulate filtering medium, which is continuously moved through a vertically positioned cylindrical annular space (2) through which the liquid to be filtered continuously flows radially from the interior to the exterior. The particulate filtering medium containing the separated solid matter is continuously tapped from the lower end of the annular space (2), transported to the top, freed of the filtered solid matter and fed back into the annular space (2) at its upper end. With this kind of method and device, to be able to prevent in a better and more simple manner blockages caused by the separated floc of solid matter, the invention provides that as particulate filtering medium a particle mixture is used with a particle-size range comprising two or more particle sizes, ranging from coarse (2.5 mm) to fine (0.4 mm) and that this particle mixture is classified and distributed before or during feedback into the annular space (2) in such a way that the particle size in the load of the filter bed becomes smaller in a radial direction moving from the inside to the outside.
    • 本发明涉及一种用于连续过滤含有固体物质的液体的方法和装置,特别是用于清洁废水,通过由微粒过滤介质构成的过滤床,该过滤床连续移动通过垂直定位的圆柱形环形空间(2 ),待过滤的液体通过其从内部到外部连续地径向流动。 包含分离的固体物质的颗粒过滤介质从环形空间(2)的下端连续地敲击,输送到顶部,从而过滤固体物质,并在其上端反馈回环形空间(2)。 使用这种方法和装置,为了能够以更好和更简单的方式阻止由分离的固体物质絮凝引起的堵塞,本发明提供了作为颗粒过滤介质的颗粒混合物,其粒度范围包括 两个或更多个粒度,从粗(2.5mm)到细(0.4mm),并且该颗粒混合物在反馈到环形空间(2)之前或期间被分类和分布,使得负载中的粒度 过滤床在从内向外移动的径向方向变小。

    • A method for removing contaminants from contaminated material such as contaminated soils and contaminated construction debris comprises the following steps: Separating the materials into a first fraction having particles of a size greater than 50 mm and a second fraction comprising remaining particles; breaking up the particles of the first fraction into particles of a size smaller than 50 mm; combining the particles of a size smaller than 50 mm and the second fraction to a combined fraction; drying the combined fraction at a temperature of between 100.degree. to 130.degree. C.; breaking up the combined fraction into particles of a size smaller than 2 mm; and subjecting the particles of a size smaller than 2 mm to a distillation process at a process temperature from between 300.degree. to 600.degree. C. Preferably, the distillation process is a vacuum distillation process with a process temperature of between 350.degree. to 450.degree. C.

    • A method and apparatus for removing pollutants from contaminated soil in which the soil is first purified from coarse constituents by screening or crushing and then subjected to extraction with washing water mixed with additives, after which the soil is separated from the washing water and additionally rinsed with rinsing water whereupon the rinsing water is freed in a purification process from the pollutants extracted from the soil. The extraction with washing water, which may contain additives if required, is substantially separate from the single or mulit-stage rinsing and sorting process; a very fine fraction having a particle size up to 150 .mu.m, and preferably up to 10 .mu.m, is separated by dry or wet sorting before extraction; and the dried very fine fraction is distilled at a temperature of 300.degree. C. to a maximum of 600.degree. C., preferably distilled in vacuo at a temperature of 380.degree. C., for purification from organic pollutants and from cyanide and mercury compounds.

    • By this method, the fluid to be filtered is led through a filter bed formed of particulate filter particles, such as sand, which filter bed is retained in an upstanding annular space. The fluid is introduced to the interior part 15 of the annular space and is led transversely to the movement the filter bed, through it and away. The filter bed is provided on the inner wall of annular space with a microfilter, such as sieve grid 16, with a mesh size of 10 to 200 microns, whereby the heavy and flocculated dirt particles settling upon the microfilter are led down and away and are drawn off together with the particulate filter particles 32. To avoid stoppages of the microfilter, it is flowingly hydraulically cleaned from the inner space. Additionally, by introduction of water in the take-off space 11 there is produced a vortex bed, whereby at this space the withdrawal of the particulate filter medium is effected with a mammoth pump 17 known per se. The compressed air for the operation of the mammoth pump 17 is supplied not steadily but pulsatingly. Thus, there are provided in the vortex bed in combination with the water supply thereto some hydraulic pulses which serve to hinder the development of bridges in and above it.
    • 通过这种方法,待过滤的流体被引导通过由颗粒过滤器颗粒(例如沙子)形成的过滤床,该过滤床保持在直立的环形空间中。 流体被引入到环形空间的内部部分15中,并且被横向地引导到过滤床的移动通过它并且离开。 过滤床设置在环形空间的内壁上,带有微孔过滤器,例如筛网格子16,网格尺寸为10至200微米,由此沉淀在微过滤器上的沉重和絮凝的污垢颗粒被引导离开, 与颗粒过滤器颗粒32一起排出。​​为了避免微型过滤器的停止,其从内部空间流动地液压地清洁。 此外,通过在起飞空间11中引入水,产生涡流床,由此在该空间处,微粒过滤介质的抽出是用本身已知的猛oth象泵17来实现的。 用于大型泵17的操作的压缩空气不是稳定地而是脉动地供给。 因此,在涡流床中与供水相结合地提供一些液压脉冲,这些液压脉冲用于阻止其中和之上的桥梁的发展。
