双语教学和团队建设作为高等院校质量工程建设的重要内容，是实现我国高校教学及科研与国际接轨的重要内容之一。本文结合《食品科学技术导论》双语教学的教学实践，分析了团队建设在双语教学中的作用，总结了双语教学实施过程中就如何保障团队建设条件、提高团队建设水平的一些尝试。As important elements of quality construction in colleges and universities, bilingual teaching and team building were important contents to integrate college teaching and research in Chinawith the world. Combined with the teaching practice of bilingual teaching in Introduction to Food Science and Technology, the role of team building in bilingual teaching was analysed, and some of the attempts to protect the conditions of team building and raise the level of team building in the implementation of bilingual teaching were summarized.
针对油田回注水中Fe2+影响悬浮固体含量的问题，本文采用活性材料催化氧化并辅以截留分离的方法，除去水中的Fe2+。考察了活化时间、材料厚度及过滤速度等因素对除铁效果的影响。实验结果表明：活性材料在活化时间6天、活性材料厚度0.8 m、过滤速度0.1 L/min条件下，能够有效去除水中Fe2+，其含量由10 mg/L降低至0.1 mg/L以内。在油田现场回注水处理时，可将水中的Fe2+含量由0.6 mg/L降低至0.05 mg/L，有利于降低水中悬浮固体含量。
In view of the Fe2+ in the reinjection water affected the content of suspend solid, the writer used the reactive material to oxidize and catalyze the Fe2+, and researched the influential factors of iron removal, such as reactive time, the thickness and the current velocity. The results showed that the reactive material removed the Fe2+ and was reduced to 0.1 mg/L from 10 mg/L when its reactive time was 6 days, the thickness was 0.8 m and the current velocity was 0.1 L/min, which was good for reducing the content of suspend solid.
