Dr. Han Benyong mainly narrated his graduation thesis and made a preliminary defense. Researcher Zhang Wudi first affirmed the richness of the experimental content and the seriousness of the experimental work. However, the process takes a long time and needs to be elaborated concisely so as to make the key points clear in the prescribed time. Secondly, in the study of preparing biodiesel from ionic liquids, whether the index other than acid value can be used to explain it. Finally, it is proposed that Han Benyong's experiment will provide more research directions for the follow-up study of biodiesel. 
Report 8 Effect of Tetracycline Antibiotics on Anaerobic Digestion of Pig Manure
Reporter: Wei Fang postgraduate student
Wei Min reported the effects of different antibiotics on anaerobic digestion of pig manure. During the discussion, Dr. Wang Chengxian raised the question whether the pig manure used in the experiment was the same and whether the antibiotic residue in the pig manure was equal to the antibiotic added. Dr. Huang pointed out that there was no comparative analysis between the antibiotic residue in the pig manure itself and the antibiotic added artificially, and put forward the original intention of determining EPS in the experiment. Questions Finally, Zhang Wudi concluded that in the analysis of the experiment, it would be better to judge the inhibitory effect of antibiotics on anaerobic fermentation of pig manure from the perspective of methane inhibition rate.

Report 10.Feasibility study on biodiesel production by biogas slurry combined with microalgae culture
Reporter: Dr. Huang Li
Dr. Huang Li mainly elaborated the steps of preparing biodiesel from microalgae, the process of synthesizing grease and the method of improving the synthesis of grease. It is introduced that microalgae can play an important role in CO2 removal from biogas through experiments. At last, we put forward how to obtain algae, whether pure culture or mixed culture, which aroused people's thinking. In the discussion section, Zhang Zhen proposed the principle that microalgae can reduce COD removal rate and the reasons for CO2 removal. Researcher Zhang Wudi analyzed the advantages of the biogas slurry: the biogas slurry has high nutrient content, which not only does not consume dissolved oxygen in the water, but also promotes the growth of plankton. Finally, some thoughts on the effect of algae on oil content are put forward, which will provide a direction for further experiments.
Report 11 "Comprehensive Utilization Project of Biogas Engineering on 2000 Mu Planting Land in Xinzheng City" Research Report
Reporter: Li Giaolin postgraduate student
Starting from the basic situation of the project, Mr. Li described in detail the site selection, feasibility and necessity, technology, project budget, benefit analysis and risk assessment, as well as conclusions and suggestions of the project. After that, Dr. Liu Jianfeng proposed whether the reason for selecting rapeseed was based on the market demand. Master Li Wenbin questioned the market price of organic-inorganic compound fertilizer and put forward that the price was higher than the actual price.Researcher Zhang Wudi said that the original intention of the project was to build more than 2,000 mu of land for biogas projects, rather than to build a certain scale of biogas projects to determine how much land to use. The output of the project is mainly concentrated on biogas and vegetable. The fertilizer produced by biogas project is all used for vegetable cultivation, not for sale.
Report 12 .A Review of the Effects of different treatments on anaerobic dry fermentation
Reporter: Zhang Zhen postgraduate student
Zhang Zhen focused on analyzing the different effects of different pretreatment methods on Biogas Dry Fermentation experiment, and then drew out his next experimental plan. Dr. Huang Li discussed the selection of materials for his experiment and explored the reasons. Some suggestions were put forward to modify the research direction. The effect of activated carbon made from walnut core added to biogas fermentation system on the experimental results was not significant, and suggestions were made to adjust the thinking. Dr. Liu Jianfeng pointed out that he did not draw his own conclusion through the comparative analysis of the experimental results in the literature review. Researcher Zhang Wudi concluded that the aim of the experiment was to solve the problem of acidification in dry fermentation. The change of gas production could not explain the problem of acidification accurately. Emphasis should be placed on the accumulation of organic acids.
Report13. Feasibility Report of Biogas Project for 10,000 Cows in Stock in Bengbu City, Anhui Province
Reporter: Wang Wenwei postgraduate student
Wang Wenwei made a feasibility analysis around the biogas engineering construction project of 10000 Cows in Bengbu County, and elaborated the final feasible conclusion of the project from many aspects. In view of his elaboration, we had a heated discussion. Dr. Yang Bin proposed that the economic benefit analysis was limited to the benefit of biogas engineering, without considering the milk and other benefits produced by cows themselves. Liu Jianfeng pointed out that there may be overlap in the schedule of the project, and that each process is not necessarily carried out in stages, but at the same time. In the selection of temperature for medium temperature fermentation, we should focus on cost accounting and not only consider the effect of gas production.
