Abstract

Abstract: Purification efficiency of beer wastewater by Lolium multiflorum is studied by means of soilless cultivation techinigue. After a 120 hours static experiment, the purification rate of TN, TP, COD, NH₄⁺-N, NO₂^--N, NO₃^--N and turbidity is respectively 54.1,82.19,66.34,69.69,90.91,57.80 and 92.59% in March,and that of TN,TP, NH₄⁺-N, CODand turbidity is 95.2,98.34,99.76,75.09 and 82.98 in May. It is proved that Lolium multiflorum can be used for purifying beer wastewater under lower temperature.
