摘要
采用臭氧氧化和生物活性炭联合技术对煤气废水生物出水进行深度处理。结果表明颗粒活性炭对煤气废水中的有机物具有良好的吸附性,吸附17天后基本达到平衡;臭氧生物活性炭工艺可有效去除煤气废水生物处理出水中残留的COD和NH4+-N,在较低臭氧投量条件下,COD总去除率平均可达70%,NH4+-N的去除率可以达到74%,基本可以满足废水一级排放标准。
Ozone-biological activated carbon(O3-BAC) combined process is adopted as the advancing treatment process for the effluent of coal gasification wastewater.The result indicates that the granular activated carbon (GAC) used has predominant adoption performance for the organic matter in the effluent and an achieve adsorption equilibrium in 17 d.It can be seen that O3-BAC process is efficiency and the ratio of COD and NH+4-N removal are 70% and 74% respectively.The advancing treatment effluents are general meet with the first standard of the wastewater discharge criterion.
