1.利用蟹壳净化水源 俄罗斯学者发现,蟹、虾的甲壳中含有一种化学物质,可用于净化受放射性物质等污染的水源。研究人员从蟹、虾的甲壳里分离出一种叫壳聚糖的物质,它经过适当处理后,可以很好地吸收水中的放射性元素、重金属盐和其它对人体有害的物质。研究人员认为,利用这种物质可以制造出新一代简易高效的水源过滤净化设备。 2.利用塑料垃圾制块状燃料 日本宣布:他们利用废袋等塑料垃圾制成的块状燃料可用来烧火炉,价格很便宜。其制法是:将塑料
1. The use of crab shell to purify water Russian scholars found that crabs, shrimps in the carapace contains a chemical that can be used to purify radioactive substances contaminated water. Researchers have isolated a substance called chitosan from the crab shell of crab and shrimp, which, when properly treated, absorbs radioactive elements, heavy metal salts and other harmful substances in the water. Researchers believe that the use of this material can create a new generation of simple and efficient water filtration and purification equipment. 2. Making use of plastic waste to make massive fuels Japan announces that they can use lumpy fuel made of plastic waste such as waste bags to burn stoves at very low prices. Its system of law is: the plastic
