摘要
水体环境是水产养殖业赖以生存的物质基础,也是实现水产养殖产业可持续发展必须解决的核心问题。随着水产养殖业大规模发展,解决养殖尾水污染、大量消耗水资源问题已经刻不容缓。以植物提取液为制剂的水处理技术,对环境友好,对自然亲和,对水产品有保生促健作用。治理后的水体主要指标氨氮浓度为0.565 mg/L,下降到0.02 mg/L,总氮浓度为1.7 mg/L,下降到0.8 mg/L,均达到并超过国家地表水标准Ⅲ类,水产品存活率提高13.75%。养殖用水完全可以循环重复使用,减少池塘换水次数。
Water environment is not only the material basis for survival of aquaculture industry, but also the core issue to achieve sustainable development. With large-scale development of aquaculture industry, it is urgent to solve the problem of pollution of aquaculture tail water and large consumption of water resources. The water treatment technology using plant extract as a preparation is environmentally friendly, has natural affinity, and has a health-preserving effect on aquatic products. After treatment, ammonia nitrogen concentration has been decreased from 0.565 mg/L to 0.02 mg/L, and total nitrogen concentration has been decreased from 1.7 mg/L to 0.8 mg/L, which meet grade Ⅲ of national surface water standard, and aquatic product survival rate increases by 13.75%. Aquaculture water can be recycled and reused, reducing the number of water changes in the pond.
