Abstract

Abstract: A compound baffle artificial wetland system consisting of new bio-cord paddings and Eichhornia crassipes used hydraulic retention time for 24 hours to highly purify micro-polluted water so that the output of water are improved. The average removal rate of chemical oxygen demand (CODMn) was 24.89% and 22.02% respectively in device A filled with bio-cord and Eichhornia crassipes and in device B only with bio-cord. Besides, the average removal rate of total nitrogen (TN) was 40.80% and 40.73%. For NH⁺₄-N, it was 73.82% and 69.42%, and total phosphorus (TP) was 47.83% and 39.76%. The output water quality in Luoshi River can be raised from the original class VIV to class ⅢⅡ of the quality standard for surface water environment (GB 3838—2002) after purification.

Key words: bio-cord, denitrification and phosphorus removal, micropolluted water resource, artificial wetland, Eichhornia crassipes
