人工湿地水质净化机理与生态工程研究进展

Mechanism of sewage purification and study progress of ecological engineering in constructed wetland

在阐述人工湿地净化污水机理的基础上,综述近年来国内外出现的各种新型污水生态处理技术:构建复合人工湿地系统、蚯蚓生态滤池、生物栅与生物浮岛、生态砾石床技术和人工水草生态净化技术.

Based on the sewage purification mechanism of constructed wetland,the new sewage purification methods using ecological engineering technology which appeared recently at home and abroad were summarized as follows：It is essential to establish compound constructed wetland systems,earthworm ecology filter ponds,bio-railings and biological floating island with eco-gravel-bed technology and artificial plants purification technology as well.
