摘要
环氧丙烷废水具有pH值高、含盐量高、Ca2+浓度高、可生化性低等特点,属难处理废水。采用"强化预处理-活性污泥-生物膜"为主体的工艺,利用厂内烟道水降低pH,去除Ca2+及CODcr,提高可生化性,再经过二级生化处理,出水可达《污水综合排放标准》(GB8798-1996)二级标准;同时利用原有构筑物进行改造,采用厂内废物作为处理药剂,减少投资,降低成本。
The effluent qualitY reaches the class II criteria of Integrated Wastewater Discharge Standard （GB8978-1996） After using ＂enhanced pre-treatment- Activated Sludge Process- biofilm＂ as main treatment, reducing pH value, removing Ca2＋ and CODer, increasing the BOD5/CODcr ratio when putting flue gas water into. It can save investment and reduce the cost because of improvement of old construction and using waste as the treating solvents.
