概述污水的生物化学处理是目前处理有机污水较常用的一种方法。污水中的有机物质借助于好氧微生物的作用,即细菌通过自身生命活动的过程——氧化、还原、合成等过程,把一部分被吸收的有机物氧化成简单的无机物,而把另一部分有机物转化为生物体所必须的营养质,组成新的原生质产生更多的细菌,细菌又能分解有机物,从而达到去除污水中有机物的目的。 Overview Biochemical treatment of wastewater is a commonly used method for the treatment of organic wastewater. The organic matter in the sewage is oxidized by the action of aerobic microorganisms, that is, the process through which bacteria lives through their own activities—oxidation, reduction, synthesis, etc., to oxidize a portion of the absorbed organic matter into simple inorganic matter, and convert another part of the organic matter. For the organism’s essential nutrients, the formation of new protoplasm produces more bacteria, and the bacteria can decompose organic matter, so as to achieve the purpose of removing organic matter in the sewage.
