永泰县工厂化淡水养殖场尾水整治策略

Tailwater regulation strategy of industrialized aquaculture farm in Yongtai County,Fujian Province

加快推进水产养殖业绿色发展,是保护水域生态环境、实施乡村振兴战略的重大举措,也是打赢精准脱贫、污染防治攻坚战的必然选择。本文详细阐述了永泰县现有工厂化淡水养殖场的基本情况、存在的问题及尾水整治情况。此次整治共拆除淡水养殖场16家,升级改造淡水养殖场21家,升级改造的淡水养殖场已全部安装并运行尾水处理设备,经有CMA或CNAS资质的第三方企业对尾水检测,结果为尾水中总磷含量均≤0.5 mg/L,符合各项排放标准要求。通过整治消除了工厂化淡水养殖企业对环境造成的不良影响,有力地推动了水产养殖环境和经济的协调发展。同时对淡水养殖场尾水治理措施进行了总结,并对现有的多个养殖尾水排放标准进行比对分析,提出存在的问题,就今后农业部门开展标准制定过程中应注意的情况提出了一定的建议。
