- 摘要:
- 南美白对虾养殖尾水具有盐度高、排放量大、硝态氮浓度高的特点。为满足江苏省《池塘养殖尾水排放标准》(DB 32/4043—2021)要求,某养殖园区采用“改良型三池两坝”工艺处理南美白对虾养殖尾水,即在传统“沉淀池-过滤坝-曝气池-过滤坝-生物净化池”组合工艺的基础上,优化沉淀池停留时间,利用生物毛刷的过滤拦截作用,强化沉淀效果;采用填装改性复配生物质炭滤料的过滤坝,进一步吸附和拦截尾水中的SS;投加优势耐盐芽孢杆菌,改良曝气池的生物菌剂活性,保证了对TN和有机物的去除效果。实际应用效果表明,“改良型三池两坝”工艺对南美白对虾养殖尾水中COD、TN、TP、SS的去除率分别为68.78%、87.35%、58.06%、78.85%,所有出水指标均达到排放标准且经济可行,可为对虾养殖行业尾水治理提供案例借鉴。
- Abstract:
- The Penaeus vannamei aquaculture wastewater has the characteristics of high salinity, large discharge amount, and high nitrate nitrogen. In response to the requirements of Discharge Standard of Water from Aquaculture Ponds (DB 32/4043-2021) in Jiangsu Province, an aquaculture park uses the improved three tanks and two dams process to treat aquaculture wastewater, which is based on the traditional combined process of sedimentation tank, filter dam, aeration tank, filter dam, and biological purification tank. The residence time of the sedimentation tank is optimized and the filtering and interception effect of biological brushes is utilized to enhance the sedimentation effect. A filter dam filled with modified composite biochar filter material is used to further adsorb and intercept SS in the wastewater. The addition of advantageous salt tolerant Bacillus improved the activity of biological agent in the aeration tank to ensure the removal of TN and organic matter. The application results show that the removal rates of COD, TN, TP and SS in the Penaeus vannamei aquaculture wastewater are 68.78%, 87.35%, 58.06% and 78.85%, respectively. All indicators meet the discharge standard requirements, providing a reference for the wastewater treatment of Penaeus vannamei aquaculture industry.
