Process for the biological purification of waste water domestic according to the process of the activated sludge

机译:根据活性污泥工艺对生活污水进行生物净化的工艺

摘要

In an activated sludge process organic materials are decomposed by means of bacteria in a first aerating stage where a relatively low oxygen-content is maintained. The thus treated water is conveyed to a first sedimentation stage and the effluent from this stage is conveyed in substantially oxygen-free condition to a second aeration stage where bacteriophogic organisms, usually protozoa, are maintained under optimum conditions of relatively high oxygen-content. Biologically purified water is obtained from a second sedimentation stage.
