摘要
针对海水对虾养殖废水中主要污染物悬浮颗粒物和氨氮的去除,构建了排水沟中沉淀及大型海藻吸附、贝藻协同净化和人工红树林湿地深度净化的生态处理工艺路线,并在相关研究基础上对各处理单元的关键设计参数进行了总结,得到一组相对较切合实际的设计参数和计算公式。
With the fast development of high-density shrimp farming industry in the coastal area in china,the discharged waster water without treatment into the sea,brought serious environmental pollution.In consideration of high concentrations of TSS and dissolved nutrients in the waste water,a design method of comprehensive ecological treatment aiming at removing these critical pollutants was applied： ecological ditches with growing algae to remove large-sized suspended particles—（hanging support bivalves and macroalgae in the purification pond） to filter suspended particulate matter and absorb the ammonia nitrogen in the wastewater—constructed mangrove wetland for further treatment of the wastewater.And based on the related research,summarize the the key parameters of each processing unit,obtain a relatively realistic design parameters and formulas.The design was proposed to provide a reference for the wastewater treatment of shrimp aquaculture.
