缺氧及两级好氧处理岳阳化工总厂部分废水的运行与分析

Operation and Analysis of Lack Oxygen and Two Give Oxygen Treating Partial Wastewater of Yueyang Chemical Industry Head Factory

介绍了岳阳化工总厂部分废水的处理工艺和设计 ,针对原水水质 COD高等特点 ,采用缺氧、两级好氧工艺。该厂进生化池 :COD浓度 10 0 0～ 14 0 0 mg/ L ,BOD3∶ COD=0 .5左右 ;出生化池 :COD浓度 <12 0 mg/ L ,低于 GB8978～1996表 4中石油化工工业规定的 级排放标准。 BOD5<10 mg/ L ,低于 GB8978— 1996表 4中石油化工工业规定的

The treatment technology and design of part waste water in Yueyang chemical industry head factory was introduced.In view of the characteristic of high COD concentration in former water quality,We adopted lack oxygen→give oxygen→again give oxygen process.
