| 摘要 |
<p>The invention concerns a waste water purification plant comprising a biological treatment reactor for treating effluent including cylindrical elements fixed on a rotary shaft (62) designed for aerobic and anaerobic micro-organism culture for degradation of organic matters contained in the effluent, said cylindrical elements being partly immersed in the effluent and having recesses, channels, or cells so as to enable oxygenation of the effluent, oxygenation of the micro-organisms and contact between the micro-organisms and the organic matters of the effluent. The invention is mainly characterised in that the cylindrical elements are thin discs (60-1 to 60-3) consisting of two substantially parallel plates (70 and 72) separated by a cellular material (74) with open cells, the outer sides of the plates serving as support to the aerobic and anaerobic micro-organism culture.</p> |
