补充资料:传统活性污泥法
分子式:
CAS号:

性质:又称普通活性污泥法。经初次沉淀后的废水与由二次沉淀池来的回流污泥在曝气池起端进入池内,通过扩散或机械曝气进行充分混合与曝气,并通过活性污泥的吸附、絮凝和氧化作用去除废水中的有机物。从曝气池流出的混合液在二次沉淀池沉淀后,沉淀出的活性污泥以进水量的25%~50%返回曝气池(即污泥回流比为25%~50%)。该法适用于处理要求高而水质较稳定的废水。其生化需氧量的去除率可达85%~95%。传氧  oxygen transfer  指(1)气相和液相之间氧的交换。(2)液体吸收的氧量与用曝气方式或充氧设备向该液体输送氧量的对比率;一般以百分率表示。
