硝化细菌对加州鲈池塘水质影响及底质净化作用

STUDY OF WATER QUALITY AND SEDIMENT PURIFICATION BY NITRIFYING BACTERIA IN A CALIFORNIA PERCH (MICROPTERUS SALMOIDES) POND

  • 摘要: 为研究有益菌硝化细菌(Nitrifying bacteria)对加州鲈(Micropterus salmoides)高密度养殖池塘水质及底质的影响, 在模拟加州鲈高密度养殖池塘单独施用硝化细菌, 通过检测养殖水体pH、氨氮(\rmNH_4^ + -N)、亚硝酸盐氮、总氮(TN)及总磷(TP)等水质指标, 底质沉积物中有机物、全氮及全磷等指标以及池塘浮游动植物量, 以评价硝化细菌处理对加州鲈高密度养殖水体水质影响及底质净化作用。结果表明, 硝化细菌能够稳定养殖水体pH, 降低水体亚硝酸盐氮浓度, 减缓养殖水体TN浓度上升, 去除底质沉积物中有机物及全磷含量, 有机物去除率达54.17%, 全磷去除率达43.34%。硝化细菌处理前期浮游动植物总量高于对照池塘, 后期逐渐减少并趋于稳定。

     

    Abstract: The purpose of this research was to study the effect of probiotic nitrifying bacteria on the water quality of California perch (Micropterus salmoides) ponds. Water quality indexes, including the transparency, potential hydrogen (pH), ammonia nitrogen (NH4+-N), nitrite, total nitrogen (TN), total phosphorus (TP), sediment organics, sediment nitrogen, sediment phosphorus and amount of plankton, were detected to evaluate water quality. The results showed that the nitrifying bacteria could stabilize pH and reduce the contents of nitrite and TN; additionally, the maximum TN removal rate was 72.5%, the maximum sediment organics removal rate was 54.0%, and the maximum sediment phosphorus removal rate was 50.0%. The total amount of plankton in the early stage of the nitrifying bacteria treatment was higher than that of the control pond, and the total amount of plankton in the later stage was lower than that of the control pond.
