新型海水养殖外排水循环利用系统研制成功由中国水产科学研究院黄海水产研究所研制出的新型海水养殖外排水循环利用系统,成为国内首个在海水中以人工湿地的原理进行养殖水处理的系统。与传统方法相比,该系统加强了脱氮除磷的效果,投资与运行费用低、能耗小,可以从根本上解决陆基海水养殖对近海环境的影响,有效节约海水资源,减少污水排放量,减缓近岸海域富营养化程度。目前,该系统已在山东胶州、辽宁营口、浙江绍兴的3家企业中投入使用,成本效益比达到了1∶5。人工湿地,实现低成本新型循环水养殖系统的核心借用
New type of marine aquaculture drainage and recycling system successfully developed by the Chinese Academy of Fishery Sciences Yellow Sea Fisheries Research Institute developed a new type of aquaculture drainage and recycling system has become the first in the sea to artificial wetlands on the principle of aquaculture water treatment system . Compared with the traditional method, this system strengthens the effect of nitrogen and phosphorus removal, low investment and operation costs, low energy consumption, can fundamentally solve the impact of land-based sea water culture on the offshore environment, effectively conserve seawater resources and reduce sewage discharge Amount, slowing the eutrophication of coastal waters. At present, the system has been put into use in three enterprises in Jiaozhou, Shandong, Yingkou, Liaoning and Shaoxing, Zhejiang Province. The cost-effectiveness ratio reached 1: 5. Constructed wetlands, to achieve low-cost new circulating water aquaculture system core borrow
