【摘要】 2009年在黄河三角洲海涂进行了毛蚶—梭鱼、青蛤—对虾立体生态养殖对水质净化作用的试验,结果表明:鱼虾贝类立体混养对水质CODMn、活性磷酸盐、挥发酚的平均去除率达50%以上,对BOD5、无机氮、硫化物的去除率达30%以上,对总氮、总磷的去除率达15%左右,平均去除率依次为:挥发酚>活性磷酸盐>CODMn>BOD5>硫化物>无机氮>总磷>总氮。鱼虾贝类立体生态养殖对水质的净化效果比较明显。更多还原

【Abstract】 The experiments of seawater quality purification in scapharcasubcrenata—barracuda and cyclina sinensis—prawn three-dimensional ecological aquaculture were carried out in the yellow river delta intertidal zone in 2009.The results showed that the removal rate of CODMn, labile phosphate and volatile phenol of aquicultural seawater exceeded 50%; the removal rate of BOD5, inorganic nitrogen and sulfide exceeded 50% also; and the removal rate of TN,TP were about 15%. The average removal rate of each pollutants were volatile phenol>labile phosphate>CODMn>BOD5>sulfide>inorganic nitrogen>TP>TN in turn. There was an apparent purifing function for aquicultural seawater in the course of fish,prawn and cowry three-dimensional ecological aquaculture.更多还原
