摘要
针对乙烯装置废碱液中所含污染物的特点,通过富集、分离、筛选等步骤从废碱液废水中,找到降解特定污染物的最佳微生物,加以培养增殖,形成特效菌种,有针对性地对特定污染物进行降解处理;由于特效菌种对污染物的承受负荷远远高于普通的生物菌种,处理效果也优于普通生物处理,因此生物强化技术处理乙烯装置废碱液具有良好的发展前景。
According to the characteristics of the pollutants contained in the waste alkali liquor of the ethylene plant, the best microorganisms for degrading the specifc pollutants are found out from the waste alkali liquor wastewater through the steps of enrichment, separation and screening, and then the microorganisms are cultured and proliferated to form specifc strains, then the microorganisms can make a targeted degradation treatment to specifc pollutants. Because the load of special bacteria on pollutants is much higher than that of ordinary biological bacteria, and the treatment effect is also better than that of ordinary biological treatment, the biological strengthening technology has a good development prospect for treating waste alkali liquor of ethylene plant.
