摘要:龟鳖温室养殖废水中的氨氮(NH4+-N)浓度非常高,化学耗氧量(CODcr)大,如果直接排放将给周边水体造成严重污染。为解决龟鳖温室养殖废水达标排放和循环利用,采用生态沟-人工湿地-净化塘组合的生物生态净化工艺技术处理龟鳖温室养殖废水。结果显示,悬浮物质(SS)、NH4+-N和总磷(TP)的去除率分别为91.3%、94.2%和94.5%,CODcr降低90.9%。研究表明,该组合工艺系统可以用作小规模龟鳖温室养殖废水高效的生物生态处理系统。

Abstract: Both the ammonia concentration and CODcr in the greenhouse turtle aquaculture wastewater are very high. If the wastewater is directly drained into the receiving water body around the aquaculture site, it will cause serious pollution. To make the greenhouse turtle aquaculture wastewater reach the emission standards and recycle the wastewater, a biological-ecological process, combined with the ecological ditch-wetland-purifying pond, was adopted to treat the greenhouse turtle aquaculture wastewater. The results showed that the removal rates of CODcr, SS, NH4+-N and TP were 90.9%, 91.3%, 94.2% and 94.5%, respectively. Therefore, the combined system could be used as an efficient biological-ecological wastewater treatment system especially for a small-scale greenhouse turtles breeding.
