摘要
湖泊的富营养化问题已成为中国湖泊环境保护中最严重的问题之一。回收利用富营养化湖泊中的浮游藻类是减轻水体中氮、磷等营养负荷 ,治理湖泊环境污染的一项重要措施。通过热解技术可将藻类转化成焦炭、生物油和合成气等多种燃料形式 ,因而是回收利用湖泊浮游藻类的一个理想途径。同木质 -纤维素类生物质相比 ,藻类作热解原料具有易预处理、易热解、易获得高产等优点 ,可以为社会提供大量优质的燃料。
The eutrophication of lakes has become one of the most severe problems in environmental protection of lakes in China. Recovery of the planktonic algae from eutrophic lakes is one important measure of controlling the environmental pollution of lakes since it can reduce the load of nutrient elements especially N and P.Algae can be converted to a variety of fuels including charcoal, bio-crude and synthetic gas by pyrolysis, so this thermochemical technique is an economical one for handling with the planktonic algae in lakes. As a good pyrolysis material, algae are easier to be pre-treated and pyrolyzed than lignocellulosic materials, and have higher yields. It can supply a great quantity of fuels for the society.
