Translation(2) 龚德福，男，1958年左右，学历不详，重庆市开县镇安镇歇马村村民。他发现库区的许多农户的人畜粪便直接排放，收割后遗留的秸秆在田间地头腐烂变质，粪水、污水四溢，既不利于新农村建设，又严重影响了三峡水库的水质，农户中原来的沼气池建造费用高，容易譬气，而且沼气的产出还受到季节温度影响，于是想着发明一种容器，可以直接生产沼气，还能移动。 2005年开始，他最先是用含有硫化镁、氧化镁等材料做成的沼气罐，出现问题后又进行了百次实验，直到2008年，他使用耐酸碱的“玻璃钢”材料，研制成了玻璃钢沼气罐。该沼气罐具有强度高、耐酸碱、抗老化、重量轻、无渗漏、可移动、施工简单等优点，还克服了一般沼气池冬天不产气的弊病，使用起来非常方便。其发酵材料既可用人畜粪便、也可用秸秆等植物（干发酵），产生的沼气不含水分、无渣、无味、安全。一个体积6立方米的玻璃钢沼气罐一天可产气3立方米左右，能满足一家人做饭、烧水和照明用电。2008年11月中旬，县长陈远辉率移民局、农委、沼气办等部门领导、专家在农户察看了龚德福发明的玻璃钢沼气罐，玻璃钢沼气罐项目已经由相关部门立项，并纳入了开县工业园区规划建设当中。这项产品刚刚投入市场，已经深受群众认可和喜欢。 Gong Defu, male, born in 1958, education level is unknown, a villager from Xiema village, Zhenan town, Kai county, Chongqing.The innovator found that many households dumped and discharged human and animal waste at random and stalks after harvest were abandoned and rotted in fields, causing waste and sewage overflow everywhere, which was both bad for the construction of new countryside and affected the water quality of the Three Gorges. Besides, it was quite expensive to construct traditional methane tank and biogas was easy to leak. Moreover, the output of biogas was influenced by temperature. So Gong decided to invent a methane tank which could not only produce biogas directly but also was removable. He had done experiments by using MgS(magnesium sulfide), MgO(magnesium oxide), etc. as materials of methane tank for hundreds of times since 2005. He finally invented this methane tank made of GFRP (glass fiver reinforced plastics).This methane tank has the advantages of high strength, acid-alkali resistance, ageing resistance, light weight, no leakage, removeability and simple construction. Besides, it overcomes the difficulty that methane tanks not produce biogas in winter. It is very convenient to use it. Both excrement of human beings and livestock and plants like stalks (dry fermented) could be used as ferment materials. The biogas produced by it has no moisture, no residue, no smell and is safe. A six cubic meter GFRP methane tank could produce 3 cubic meter bioga
