摘要
文中所用生态填料为生态纤维及陶粒,生态纤维是一种模拟天然水草形态加工而成的新型水处理材料。其具有比表面积大、去除有机物容积负荷高、生物附着性好、空隙可变、不易堵塞、适应性强、操作管理简便等优点;陶粒具有较高的孔隙率及适中的密度。采用人工湿地作为构筑物对崇明前卫生态村水体进行处理,结果表明,经此工艺处理后的水体,COD、TP、TN、氨氮等指标达到或优于国家Ⅲ类水质标准。
The ecological padding refers to ecological fibre and ceramic particles in this paper. The ecological fibre is a new water treatment material which was processed by simulation wild water plant and possesses the advantages of high removal rate for organic volume load, better biological adhesiveness, changeable void, being not liable to be blocked, strong adapitability, simple operation and management etc. Its high porosity and moderate density are advantageous to growth of microorganisms. In the paper, a constructed wetland was used as structure to carry out the treatment for an ecological village in Chongming County, Shanghai Municipality. The results showed that after the water body was treated by this process, COD, TP, TN, NH3-N, etc. indexes all reached or were superior to the national Ⅲ class water quality index.
