摘要
[目的]研究乳化剂废水的COD去除效果,为工程项目的设计、调试、运行等工作提供试验依据。[方法]采用UASB+SBR工艺处理乳化剂废水,并探讨了运行过程中出现的问题。[结果]中试稳定运行71 d,在进水COD浓度(最高10 924 mg/L,最低2 880 mg/L,平均5 751 mg/L)波动较大的情况下,UASB的出水COD去除效率维持在70%以上,SBR的出水COD去除率在60%以上,出水能够达标排放。[结论]该组合工艺对乳化剂废水具有较好的处理效果。
[Objective] The aim was to study the COD removal effect of emulsifier wastewater and provide experimental basis for the design,adjustment and operation of project.[Method] Using UASB＋SBR technology to process emulsifier wastewater,the problems in operation process were discussed.[Result] The experiment carried out for 71 d,under the situation of large changes of COD concentration（the highest： 10 924 mg/L,the lowest： 2 880 mg/L,mean value： 5 751 mg/L）,COD removal efficiency of UASB was around 70% and the COD removal efficiency of SBR was above 70%,which met the emission standard.[Conclusion] The combined technology had good treatment effect on the emulsifier wastewater.
