| 摘 要： | 目的]探讨微生物氧化红薯淀粉废水除锰技术的应用。方法]从红薯碎渣中采集锰氧化细菌,利用选择性培养基纯化富集,通过浸泡法固定在石英砂滤床上,将离子态的二价锰氧化成二氧化锰颗粒,截留在石英砂上,达到去除锰的目的。结果]鲜红薯中富含二价锰,鲜红薯加工各工艺环节产生的废水锰含量为1.0~5.0 mg/L,废水通过锰氧化菌处理的石英砂后,滤后水锰含量小于0.1 mg/L,符合地表水环境质量标准排入环境。结论]微生物氧化处理红薯加工产生的废水,菌种容易获取,除锰工艺简单,操作、管理、维护方便,无药剂费用支出,生物去除红薯淀粉废水具有很高的经济效益和社会效益。

| Abstract: | Objective]The aim was to explore the application of microorganism oxidizes waste water starch of sweet potato.Method]The man-ganese oxide bacteria was collected from the disintegrating slag of sweet potato;the selective medium was utilized to purification,and fixed on the quartz sand straining material by soaking,then diatomic manganese with ionicity would oxide to manganese dioxide granule,and held back it on the quartz sand straining material to achieve the effect of manganese removal.Result]The fresh sweet potato was rich in two valent manganese. The manganese content was 1.0-5.0 mg/L in the waste water produced by the processing of fresh sweet potato.The content of manganese in the filtered water was less than 0.1 mg/L after the waste water was treated with quartz sand by bacteria.It was qualified to surface water environment quality standard,and it could be discharge to the environment.Conclusion]The microbial oxidation treatment of the waste water produced by the processing of sweet potato obtains the culture easily.Additionally,manganese removal is easy to operate,manage and maintain,without any ex-pense on medicament.Hence,removing the waste water of sweet potato biologically has high economical benefits. |
