bwin必赢研究生于4月16日晚开展学术交流活动，此次活动由17级研究生卢上飞主持，徐成华经理参加活动，并为同学们的科研工作提出宝贵意见。

本次学术交流的学科方向为水污染控制理论与技术、废弃物处置及资源化，由江世林等6位同学进行汇报，将各自在科研工作上取得的进展及遇到的困难和大家沟通、交流。主要汇报内容为江世林：芦苇活性炭对猪场废水抗生素的降解研究；周禺伶：固定化微藻处理猪场废水的性能研究；秦嘉伟：新型生物滤池—人工湿地处理猪场废水研究；杨豪：国内低温条件下污水脱氮除磷的效果；刘宗杨：生物滤柱去除微污染水源中的锰、有机物；贾晓娟：生物炭对底泥重金属污染的研究。

徐老师针对江世林同学遇见的科研困难提供宝贵建议，建议该同学在制备芦苇活性炭的过程中加入一定的活性剂，并且在低温焙烧过程中控制好升温速率，另外，要认真研究猪场废水的处理模型，思考在实际运用中的意义；在周禺伶同学提出固定化颗粒无法成球的问题时，卢上飞根据自身研究方向建议控制滴落高度及换用注射器，徐老师站在学院发展角度建议周禺伶在光合作用方向开展科研工作，同时希望全院师生在诸如生物柴油等课题上多花功夫，另外，徐老师结合自身经历，建议同学们投稿时要认真细致检查，编辑部的要求要认真查看，诸如限值字符等要求；徐老师建议秦嘉伟同学拍摄图片时要简洁，尽量让背景整洁、突出主题，结合自身审稿经历，指出图表整洁的重要性，另外建议该同学思考铁、镁等载体是否会对水体造成二次污染。

学术交流活动结束之际，同学们感觉收获颇多，了解到了关于水污染控制理论与技术、废弃物处置及资源化的相关知识；同时在徐老师的指导下学习了投稿、图表处理的专业知识，了解了学院的发展动态及相关国际交流情况，可以为同学们以后的科研工作及日常生活提供巨大的指导意义。

Brainstorming and advancing to a New level of Scientific Research

—Academic Exchange activities of the Institute of Resources and Environment

On the evening of April 16, graduate students from the Institute of Resources and Environment of Chengdu University of Information Engineering launched an academic exchange. The event was presided over by Lu Shangfei, a graduate student of Grade 17, attended by Dean Xu Chenghua, and offered valuable suggestions for the scientific research work of the students.

The subject direction of this academic exchange is water pollution control theory and technology, waste disposal and resource utilization. Six students, such as Jiang Shilin, will report on their progress and difficulties in scientific research and communicate with each other. The main reports are as follows: the degradation of antibiotics in pig wastewater by Reed activated carbon; Zhou Yuling: study on the performance of immobilized microalgae in treating pig farm wastewater; Qin Jiawei: study on the treatment of pig wastewater by new biological filter-constructed wetland; Yang Hao: the effect of nitrogen and phosphorus removal in domestic sewage at low temperature; Liu Zongyang: removal of manganese and organic matter from slightly polluted water sources by biological filter column; and Jia Xiaojuan: study on heavy metal pollution in sediment by biocharcoal.

In view of the difficulties encountered by Jiang Shilin in scientific research, Mr. Xu suggested that the student should add certain active agents in the process of preparing Reed activated carbon, and control the heating rate well in the low temperature roasting process. In addition, The treatment model of pig farm wastewater should be studied carefully, and the significance of practical application should be considered. When Zhou Yuling raised the question that immobilized particles could not be formed into balls, Lu Shangfei suggested to control the dropping height and replace the syringe according to his own research direction. From the perspective of the college undefineds development, Mr. Xu suggested that Zhou Yu-ling should carry out scientific research in the direction of photosynthesis. At the same time, he hoped that the whole school would devote more effort to topics such as biodiesel. In addition, Mr. Xu combined her own experience. It is suggested that students should examine carefully and carefully when submitting their contributions, and that the requirements of the editorial department should be carefully checked, such as the limited value characters and so on. Mr. Xu suggested that Qin Jiawei should be concise when taking pictures, try to keep the background clean, highlight the theme, and point out the importance of neatness of charts in combination with his own experience of reviewing manuscripts. In addition, he suggested that the classmate should think about iron. Whether magnesium and other carriers will cause secondary pollution to the water.

At the end of the academic exchange activities, the students felt a lot of harvest, and learned about the theory and technology of water pollution control, waste disposal and recycling; At the same time, under the guidance of Mr. Xu, I have studied the professional knowledge of contribution, chart processing, the development of the college and related international exchanges, which can provide great guiding significance for students undefined scientific research work and daily life in the future.
