摘要
乙烯装置的污水通过加强预处理和一级处理,并选择先进的二级生物处理工艺,则可使其污水处理获得最佳效果。从技术经济指标,论述了无剩余污泥的生物膜法优于活性污泥法。
If waste water from ethylene plant is pretreated,or primary stage trea- ted,and followed by an advanced secondary biological treating technique, best results can be achieved,proving that the biological film process is superior to the activated sludge one as indicated by technological and eco- nomical indexes shown.
