化工高盐度废水治理技术的探讨

Discussion on High Salinity of Wastewater Treatment Technology

针对化工生产废水特性,开发了能够适用于"含酚型多环结构且废水盐度高可生化性差"的生产废水的特殊耐盐菌种。研究结果表明,该特殊菌种能够适用盐度高达30g/L的废水,生化处理后废水的COD可降到0.3g/L以下(达到纳管排放的标准)。埃格多相催化反应器、埃格菌种和埃格生化床等构成的废水处理工艺流程,较好地解决了香精香料等化工生产过程废水生化处理的技术"瓶颈",提高微生物降解效率,同时降低了成本。

The special salt-tolerant bacteria developed for the chemical engineering could be used as ＂flavortype polycyclic structure and the salinity of wastewater＂.The results showed that the special bacteria could be used for wastewater with salinity up to 30 g/L,and the COD of wastewater after biochemical treatment could be reduced to 0.3 g/L to meet the standard of nanotube discharge.The wastewater treatment process containing the Accele-tech multiphase catalytic reactor,Accele-tech bacteria and Acceletech biological fluidized bed solved the ＂bottleneck＂ of the biochemical treatment of wastewater in the process of flavor and fragrance production,which greatly improved the degradation efficiency of microbes and reduced the cost.
