Effectiveness of Purifying Polluted Water Quality by Caisson

Abstract:

The functional relationships of the ecological structure constituted by bacillus - matrix - plant and removing COD_Cr, TN and TP of the polluted river was probed. The results showed that the removal rate of TP by the combination of bacillus (imported to plant roots), limestone, Cyperus alternifolius and Iris pseudacorus was the highest and up to 79.85%; The removal rate of TN and COD_Cr by the combination of bacillus (immersed in the matrix), ceramsite, Ceratophyllum demersum and Iris pseudacorus were the highest and 65.36% and 62.21%, respectively. The removal of COD_Cr, TN and TP under bacillus immersed in a matrix or import around plant roots were significantly higher than the bacillus was put into water; Limestone for removal rate of TP was significantly higher than medical stone and ceramsite; The ceramsite for removal rate of TN was significantly higher than medical stone and limestone; The removal efficiency of the t COD_Cr, TN and TP of sewage by the configuration of Cyperus alternifolius and Iris pseudacorus were all the highest.
