Study on Four Different Vegetation Types Treating the Sanitary Sewage

Abstract:

The sanitary sewage is treated with four different vegetation types by means of artificial surface runoff. Results show soil+ Cynodon dactylon L. + Festuca arundinacea Schreb is the best vegetation type in treating the sanitary sewage, and the total removal of it is 80.24% TN, 62.99% TP, 74.85% BOD₅, 39.73% COD and 58.64% TOC respectively in the course of trial, which indicates that the mixed vegetation type made up of plants and soil is better than the pure soil vegetation type, and the complementary collocation of complex plants is better than the single plant.Five water-quality indexes of the sanitary sewage removed by the single vegetation type are also studied, and it shows that there are some differences among them from high to low as follows: TN>BOD₅>TP>TOC>COD.
