Industrial pollution discharges from washing fuel oils pose severe problems for the environment, particularly for the marine environment receiving these discharges. This work evaluates the biological treatment performance of wastewater (90 m/h) rich in organic matter with low biodegradability using a sequential batch reactor (SBR) on a laboratory scale. The test using SBR was carried out for 25 days on a continuous cycle of 24 h (30 min of filling, 17 h of aeration, 4 h of anoxia, 2 h of settling, and 30 min of emptying). The feasibility of alternative sources of microorganisms from urban wastewater. The performance of the batch sequencing reactor was evaluated using turbidity, total suspended solids, chemical oxygen demand (COD), biological oxygen demand (BOD), ammonium, nitrate, and phenol as indicators. The results obtained showed that the COD/BOD ratio and the pollutant load vary from one campaign to another. The removal efficiency of COD, BOD, TSS (Total suspended solids), ammonium, nitrate, and phenol varies from 81%, 91%, 72%, 100%, 52%, and 63%. Thus, SBR-type treatment could be an interesting way to reduce pollution due to its simplicity, less space occupation, low energy consumption, and not requiring highly qualified personnel.
工业燃料油洗涤废水的排放对环境,特别是对接收这些排放物的海洋环境造成严重问题。本工作在实验室规模上使用序批式反应器(SBR)评估了富含有机物且生物降解性低的废水(90 m/h)的生物处理性能。使用 SBR 的测试在 25 天内连续进行 24 小时循环(30 分钟填充、17 小时曝气、4 小时缺氧、2 小时沉淀和 30 分钟排空)。探讨了从城市污水中获取替代微生物源的可行性。使用浊度、总悬浮固体、化学需氧量(COD)、生物需氧量(BOD)、氨氮、硝酸盐和苯酚作为指标评估间歇序列反应器的性能。获得的结果表明,COD/BOD 比和污染物负荷在一次运行到另一次运行中变化。COD、BOD、TSS(总悬浮固体)、氨氮、硝酸盐和苯酚的去除效率分别为 81%、91%、72%、100%、52%和 63%。因此,SBR 型处理因其简单、占用空间小、能耗低且不需要高度熟练的人员而成为减少污染的一种有趣方法。
