[Preliminary study on purification function of reed wetland for nutrients from land sources].
The preliminary study on purification function of reed wetland for nutrients from land sources were conducted by irrigation channels and lysimeters. The results show that the purification rates for N, P and CODcr are from 41.7%-64.71% in the channels and 60.0%-75.92% in the lysimeters. The contents of N and P reached the national second level standards of sea water after filtration by lysimeters. By harvest, the good recycle between wetland and land is formed without accumulation.
