摘要：This paper investigated the improvement of the water quality in the synthetic polluted landscape water by adding inorganic salt of trace elements B, Mn, Zn, Cu, Mo with bio-stimulant, and compared the influences of different elements. The results showed that elements B and Mo had significant effects on pollutants removal. The highest removal rates were 70.6% (CODCr (chemical oxygen demand)), 50.0% (NH3-N (ammonia nitrogen)), 23.6% (TP (total phosphorus)) in the sample with element B and bio-stimulant, and 58.8% (CODCr), 54.5% (NH3-N), 28.5% (TP) in the sample with Mo and bio-stimulant. The removal rates of CODCr and TP were nearly 15% and 13% higher than the sample only with bio-stimulant. However, NH3-N concentration in all these samples was not reduced effectively. ? 2011 IEEE.
