摘　　要：本文研究了几种方法对养虾废水的处理效果。在水体自净作用及投加翡翠贻贝、细基江蓠繁枝变种、活菌制剂和混合投加上述三种生物等5种处理条件下,测定了养殖废水中的氨、亚硝酸盐、硝酸盐、总氮、磷酸盐、总磷、溶解态COD、颗粒态COD、总COD、浮游植物总数、浮游动物总数和细菌总数等水质指标。结果表明:处理过程中各营养负荷变化趋势不同且相互之间有联系;各种处理对无机氮的减少有一定效果,并都使细菌总数明显下降;各处理不能降低COD含量,但可以改变COD形态;投加贻贝能明显抑制浮游植物的数量。Effects of several treatments in shrimp pond effluents was studied.Phosphate,total phosphorous,phytoplankton,zooplankton and bacteria,dissolved chemical oxygen demand,paniculate chemical oxygen demand,and total chemical oxygen demand were measured under five treatments,in which four biofilters were mussels Pernav Viridis,red algae Gracilaria tenuistipitata var.Liui Zhang et Xia,bacteria and mixture of these three organisms above,respectively,and the fifth one was the self^purify treatment.The results showed that 1) there were differences among the trends of fluctuation in these nutrient content,and interrelations among some nutrients were observed,2) the concentration of dissolvable nitrogen and the size of bacteria population decreased by all treatments,3) contents of COD can not be removed,but the forms of COD were transformed,4) mussel removed phytoplankton obviously.
