摘要
应用高效微生物光合细菌、硝化细菌、复合细菌降解水中污染物,对其修复性能进行研究.结果表明:投加微生物4 d后出现修复效果,20 d修复效果达到最佳状态,高锰酸盐指数(CODMn)、总氮(TN)、总磷(TP)、叶绿素a(Ch1.-a)都大幅下降;微生物最佳投加量150 mg/L,投加周期40 d.
Some high effective microbes,photosynthetic bacteria,nitrifying bacteria,and compound bacteria etc.were used,to degrade pollutants of lake and the restoration characteristics was investigated.The experimental results showed that the restoration effect appeared 4 days later and got the best condition 20 days later.CODMn,TN,TP and Chl.-a decreased rapidly.The best inoculation amount was 150 mg/L and adding bacteria cycle was 40 days.
