富马酸废水厌氧处理试验研究

[目的]探索厌氧生物法处理富马酸废水的可行性。[方法]先分阶段将原废水稀释至一定浓度，调节原水pH值，通过蠕动泵送入厌氧反应器进行生物处理，出水再循环至反应器，测定不同反应时间出水的化学需氧量和pH。[结果]在污泥驯化阶段，进水的化学需氧量浓度约为1564mg／L，经过约48h的连续运行，化学需氧量的去除率可达到约81％；在提高负荷和稳定运行阶段，进水的化学需氧量浓度约为10377mg／L，经过约32h的连续运行，化学需氧量的去除率可达到约60％，可见应用厌氧反应器对处理富马酸此类高浓度有机废水具有良好的作用。[结论]该研究为企业废水处理提供了科学依据。

Study on Anaerobic Treatment Experiment of Fumarate Wastewater

[Objective]The aim was to explore the feasibility of fumarate wastewater treatment by anaerobic biological treatment.[Method] The original wastewater was diluted to a certain concn.by stages and its pH value adjusted,then it was sent to the anaerobic reactor by peristaltic pump to biologically treat,then the effluent was recycled and reached the reactor,the chemical oxygen demand(COD) and pH of the effluent in the different reaction times were detected.[Result]During the sludge acclimation stage,the concn.of the influent COD was 1 564 mg/L and after continuous operation for 48 h,the removal rate of the COD could reach about 81%;at the stages of increasing load and stable operation,the concn.of the influent COD was 10 377 mg/L after continuous operation for 32 h,the removal rate of the COD could reach about 60%,which showed the anaerobic reactor had good effect on the treatment for this kind of high concn.of organic wastewater such as fumarate.[Conclusion]The research provided the basis for the industrial wastewater treatment.
