摘要
对生物促生剂（Bio-energizer，BE）净化受污水体的效果进行了试验研究。结果表明：生物促生剂在低浓度时（小于1 ml／m^3），水体修复效果不明显；当浓度在3ml／m^3以上时，可以有效的加快水体中N、P类营养物的降解，可使NH4^＋ -N和TN分别由3．6—4．4mg／L和4．4—4．9mg／L降低至0．13-0．18 mg／L和0．39—1．06 mg／L，PO4^3- -P和TP分别由0．03-0．04mg／L和0．11—0．12mg／L降低至0．004-0．008mg／L和0．025-0．04mg／L。COD在试验过程中有上升的趋势。
The study of purification efficiency of polluted water remediation by bio-stimulant named Bio-energizer （BE） was carried out. The results show that the purification efficiency is unobvious when the concentration of BE is less than 1.0ml/m^3.The biodegradation of nitrogen and phosphorus can be enhanced when the concentration of BE is more than 3ml/m^3. For the latter case, the concentrations of NH4^＋ -N and tin can be reduced from 3.6 - 4.4mg/L and 4.4 - 4.9 mg/L to 0.13 - 0.18mg/L and 0.39 - 1.06mg/L, respectively; and the concentrations of PO4^3- -P and TP can be reduced from 0.03 - 0.04mg/L and 0.11 - 0.12mg/L to 0.004 - 0.008mg/L and 0.025-0.04mg/L, respectively. COD has an increasing trend during the experiment.
