生物强化技术在河道水体治理中的应用

Application of Bioaugmentation Technology in River Water Treatment

以琼江河潼南区小渡段为试验段,研究了以投加复合微生物菌剂为主、底泥曝气为辅的生物强化技术对水体中COD Cr、NH 3-N、TP的降解效果。结果表明,对试验水体进行生物强化之后,COD Cr、NH 3-N、TP的去除率分别达51.72%、41.44%、52.38%,水质稳定达到《GB 3838—2002》地表水环境质量标准的Ⅲ类水标准。说明生物强化技术可以有效地解决自然水体中污染物含量超标、水环境状况差等问题,为河道水体治理提供新的思路。

Taking the Xiaodu section of the Qiongjiang River as an experimental section,this study analyzed the degradation effects of COD Cr,NH 3-N and TP in water by bioaugment technology accompanying with sediment aeration.The results of this experiment showed that after taking bioaugmentation technology into water body,compared with the past,the water pollution was reduced.The removal rates of COD Cr,NH 3-N and TP were 51.72%,41.44%and 52.38%,respectively,and the water quality was stable to meet the Class III of the surface water environmental quality(GB 3838—2002).It illustrated that bioaugmentation technology could effectively solve the problems of excessive pollutant in natural water bodies and ameliorate the condition of polluted water.In short,bioaugmentation technology also provided a new idea of river water treatment.
