1、 xx 集团制革废水氧化沟工艺治理的设计集团制革废水氧化沟工艺治理的设计 摘 要 本文应用氧化沟技术对xx集团皮革废水治理工艺进行初步设计和计算。氧化沟 生物处理工艺在制革废水处理中的应用是成功的，它最突出的优点是处理效果好， 在本工程设计中，氧化沟进水COD平均浓度在1700mg/l时，可确保处理后COD降至 150mg/l左右， COD、 硫化物、 动植物油、 色度等的去除率可分别达到92.12%， 98.17%， 99.10%和85.15%。它的另一特点是采用高效表面机械曝气机，可以在不中断运行的 情况下，在平台上维修机械设备，便于维护管理。 关键词：关键词：氧化沟；处理工艺；皮革污水处
