【摘要】 为调查天津市海水工厂化养殖尾水排放及处理情况，选取了10家代表性的海水养殖企业进行尾水水质和尾水处理效果调查。参照《海水养殖尾水排放要求》（2007版），自2019年5月至2021年3月，采取了57组样品，分别测定了无机氮、COD、悬浮物、活性磷酸盐、p H值和盐度等指标。结果表明，工厂化养殖尾水的COD、悬浮物、无机氮和活性磷酸盐均有超标情况，超标率分别为22.81%、26.32%、84.21%和85.96%。由此可见，目前天津市工厂化养殖尾水整体水质情况不够理想，现有的尾水处理效率仍需要进一步提高；《海水养殖尾水排放要求》（2007版）中的相关标准过于严格，对于工厂化养殖尾水不太适用。更多还原

【Abstract】 In order to investigate the discharge and treatment of tailwater from factory aquaculture in Tianjin, ten representative aquaculture enterprises were selected to investigate the tailwater quality. 57 water samples were collected from May 2019 to March 2021 and according to the “Sewage Requirements of Mariculture Tailwater”(2007 edition)the inorganic nitrogen, COD,suspended solids, active phosphate, pH and salinity were determined respectively. The results showed that inorganic nitrogen,COD, suspended solids and active phosphate all exceeded the standard, and the exceeding rates were 22.81%, 26.32% 84.21%,and 85.96%, respectively. Therefore, at present, the overall water quality of industrial aquaculture tailwater in Tianjin was not good enough and the existing tailwater treatment efficiency still needs to be further improved; the relevant standards in “Sewage Requirements of Mariculture Tailwater”(2007 Edition)are too strict and are not applicable for the tailwater from industrial aquaculture.更多还原
