Abstract:

The pollution and ecological degradation of the artificial landscape water have become current key environmental problems. In order to seek the control ways of the water-body eutrophication pollution, this research is studied on experimentation which takes ecological restoration to improve water quality of the artificial lake using Bacillus subtilis and Scindapsus aureus in a new campus in Xi’an City. All processes and methods of test are conducted in accordance with their area of the procedures and standards as stipulated by the state. The experimental results indicate that the eutrophic water is purified effectively by Bacillus subtilis and Scindapsus aureus. The effect of purification of Bacillus subtilis is better than that of Scindapsus aureus in the short term and the highest removal effect of Total Phosphorus is 85%. The purification efficiency increase obviously when Bacillus subtilis is used in combination with Scindapsus aureus. The average removal rates of TN, TP, Chl-a, NH3-N, CODMn in wastewater were all higher than 80%.
