摘要
白洋淀每年产芦苇约10万t,其中苇箔是白洋淀地区的传统产品,利用芦苇量最大。在加工苇箔和工艺品过程中,大量的苇叶、苇根、苇尖被丢弃,扔到河沟河汊。现有研究表明,成熟芦苇叶片、叶鞘中全氮含量为地上茎氮含量的8~9倍,磷含量为地上茎磷含量的6~7倍。可见,产品加工过程中废弃下脚料的丢弃将对水体造成二次污染。在白洋淀开展芦苇成型燃料资源化利用项目,不但能将芦苇及废弃物变废为能,还可以降低当地农户用能支出,增加收入。同时解决废弃物污染水质问题,改善环境和空气质量。
Baiyangdian produces the reed 100 000 tons every year. Reed matting are traditional products in Baiyangdian area, and the use of reed quantity is the biggest. In the processing of reed matting, a lot of reed leafs, the reed roots, the reed tip are discarded into the brook and river branch. The existing research indicated, the total nitrogen content in leaf and sheath in mature reed was more than 8 ~9 times of the stem nitrogen content, phosphorus content was 6 ~7 times. Obviously, the waste products in the product processing will cause secondary pollution of water bodies. Reed fuel resources utilization pro-jects in Baiyangdian Lake, both reed and waste can turn waste to energy, reduce expenditures for local farmers and increase their income, while addressing waste water pollution problems, improving the environment and air quality.
