微孔增氧对养殖池塘水质及溶氧的影响

摘要

为探明池塘中安装微孔曝气增氧机对池塘水质、溶氧量的影响,分别对安装微孔曝气增氧机和喷水式增氧机的池塘进行水质相关指标和水体溶氧量监测.结果表明:松浦镜鲤养殖池塘中安装微孔曝气增氧机的立体增氧效果优于喷水式增氧机,尤其是对下层水体增氧效果明显,能降低水体中的亚硝酸盐、氨氮和硫化氢,优化养殖池塘水质.%The related water quality indexes and water dissolved oxygen amount of aquaculture ponds installed with micro-pore automatic aerators and spray automatic aerators were analyzed to study the effects of micro-pore automatic aerator on water quality and dissolved oxygen amount of an aquaculture pond and provide the basis for application of micro-pore automatic aerator.Results:The three-dimensional oxygen aeration effect of Songpu mirror carp aquaculture pond installed with micro-pore automatic aerators is better than the aquaculture pond installed with spray automatic aerators,especially for the obvious aerobic effect on lower water body.The micro-pore automatic aerator can reduce nitrite,ammonia nitrogen and sulfuretted hydrogen content in water body of an aquaculture pond and improve aquaculture water quality.
