生态弹性填料及陶粒在微污染水体处理中的应用研究(英文)

生态弹性填料是一种模拟天然水草形态加工而成的新型水处理材料,近年来在污水处理中得到了广泛应用。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,所有这些都有利于微生物的生长。本文采用人工湿地作为构筑物对崇明前卫生态村中心湖的水体进行处理,结果表明,经此工艺处理后的水体,CODCr、TP、TN、氨氮等指标达到或优于国家三类水质标准。并为工程实施提供了科学依据。

Applied Study of Ecological Fibre and Ceramic Padding for Micro-polluted Water Treatment

The ecological fibre is a new water treatment material that is processed by simulating the shape of wild water plant. In recent years it has been applied broadly in sewerage treatment for its following advantages: big specific surface area; high capacity in removing organic matter; good microbiological adhesiveness; variable pore sizes; wonderful performance in preventing jamming; flexibility in operation and management, etc. Ceramic padding has high porosity and moderate density; all of these are favorable to the growth of microorganisms. This paper discussed treating the micro-polluted water by using arts and crafts of constructed wetland, the results show that some indexes of the treated water reached or exceeded band 3 national water quality standard, these indexes include CODCr, TP, TN and NH 4-N and so on. The results can provide reference for project design.
