海水池塘养殖园区排放水综合生态净水技术研究

本研究以海水池塘养殖园区排放水集中设施化处理为切入点,集成泡沫分离、生物滤池及大型藻等多种生态修复技术,构建了海水池塘养殖园区排放水综合生态净水系统。经过综合生态净水系统处理,池塘养殖排放水中化学耗氧量(COD)、氨氮(NH4-N)、亚硝氮(NO2-N)、硝氮(NO3-N)、溶解无机氮(DIN)及活性磷酸盐(DIP)综合去除率平均分别为40.84%、89.37%、86.88%、93.75%、78.74%和59.73%。通过该技术可明显改善园区排放水质量,基本可以实现各项指标的达标排放。

Research on Comprehensive Ecological Water Purification Technology of Discharged Water from Aquaculture Pond in Fishery Park

The centralized facility treatment of discharged water in aquaculture pond of the fishery park was taken as an entry point,various environmental engineering ecological restoration technologies such as foam separation,biological filter and large-scale algae were integrated to construct an ecological water purification treatment system of the discharge water in the marine-pond aquaculture park. After treated by the integrated ecological water purification system,the average removal rate of the chemical oxygen demand (COD),ammonia nitrogen (NH₄-N),nitrous nitrogen (NO₂-N),nitrate nitrogen (NO₃-N),dissolved inorganic nitrogen (DIN) and active phosphate (DIP) in the pond culture discharge water was 40.84%,89.37%,86.88%,93.75%,78.74% and 59.73%,respectively.This technology can significantly improve the quality of the water discharged from aquaculture pond and various emission indicators can basically achieve the standard.
