| 摘 要： | 采用砂滤－UBF厌氧－絮凝沉淀工艺处理高浓度Zn5-ASA医药废水。实验结果表明，对于COD为8000－10000mg/L，色度7000－9000倍的Zn5-ASA废水，加石灰乳和H2SO4预调，经砂滤柱过滤后，COD会去除20％左右；再进以聚丙烯环为填料的厌氧UBF反应器，HRT为10.57h，COD去除率达83％－89％；出水再经化学絮凝沉淀后，无色透明，COD浓度远小于1000mg/L，符合GB8978－96三级排放标准要求，且色度小于10倍。

| Abstract: | The process of sand filter UBFanaerobic flocculant precipitation has been employed to treat high strength Zn5 ASA medicine wastewater.The experiment results showed that adjusting beforehand 8000 10000mg/L Zn5 ASA wastewater of COD concentration with lime and H 2SO 4 could produce a large number of flocculant precipitation,and COD could remove 20% or so through sand filter column.The sand filter effluent was used as influent of UBF reactor with polypropylene ring filter.When HRT was controlled at 10.57h,the removal rate of COD could achieve 83% 89%.After chemical flocculant precipitation,the effluent COD concentration was much less than 1000mg/L,the colority was less than 10 bei.The effluent conformed to GB8978 96 the third emission standard. |
