摘　　要：对甲鱼养殖产生的温室废水和外塘废水的污染情况进行分析,发现温室废水COD、TP、TN、氨氮浓度较高,污染程度明显高于外塘废水,将温室废水和外塘废水混合后集中于囤水池中,采用生物膜—活性污泥(HYBAS)工艺对甲鱼养殖废水进行处理。结果表明,HYBAS工艺对COD、TP处理效果较好,平均去除率分别为63.76%、59.32%;受冬季低温影响,HYBAS工艺运行前期对TN、氨氮去除效果较差,而运行后期去除效果良好,后期TN、氨氮平均去除率分别为42.84%、85.71%,处理出水总体满足《地表水环境质量标准》(GB 3838—2002)中Ⅳ类标准和《浙江省水产养殖池塘生态化建设与改造规范》养殖废水排放标准。HYBAS工艺建设运行费用低、抗冲击负荷能力强、处理效果良好,是一种简单易行的甲鱼养殖废水处理工艺。Pollution of the turtle breeding wastewater including greenhouse wastewater and outer pond wastewater was analyzed. It was found that the concentration of COD,TP,TN and ammonia nitrogen in greenhouse wastewater was high,and the pollution degree was obviously higher than that in outer pond. The wastewater in greenhouse and outer pond was mixed and collected in the pond,and then using hybrid-biofilm-activated sludge( HYBAS) technology to treat the turtle breeding wastewater. The results showed that the HYBAS process had perfect performance on COD and TP removal,and the average removal rate of COD and TP was 63.76% and 59.32%,respectively. Due to the low temperature in winter,the removal efficiency of TN and ammonia nitrogen was poor in early stage,while the removal efficiency was better in the later stage,with the average removal rate of TN and ammonia nitrogen was 42. 84% and 85. 71%,respectively. The treated water met the class Ⅳstandards of'Surface water environment quality standard'( GB 3838-2002) and discharge standard of'Standards for the ecological construction and renovation of aquaculture ponds in Zhejiang Province'. The HYBAS process had the advantages of low construction cost,strong shock load resistance and good treatment effect. It was a suitable process for treating turtle breeding wastewater.
