臭氧－生物活性炭工艺处理化工污水中试研究

针对兰州石化公司污水处理厂二级生化处理出水可生化性较低,色度比较高的问题,通过采用臭氧-生物活性炭工艺(O3-BAC)对污水处理厂二沉池出水进行深度处理,分析了该工艺对CODCr、氨氮、色度的处理效果。结果表明:处理后出水CODCr为26.7mg/L,氨氮为0.18mg/L,色度约5倍,效果良好。

Pilot Study of Chemical Sewage Treatment by Ozone-biological Activated Carbon Process

Due to the low biodegradability and the heavy chromaticity of the secondary biological treatment effluent in the sewage treatment plant of Lanzhou petrochemical company,we adopt an ozone-biological activated carbon process(O3-BAC) to further treat the effluent of the secondary sedimentation tank and analyze the treatment effect on CODCr,ammonia nitrogen and chromaticity.The results show the concentration of the treated effluent CODCr is reduced to 26.7 mg/L,ammonia nitrogen to 0.18mg/L and chromaticity to 5NTU.
