摘要
该研究以一种农业废弃物新会柑汁(直接使用或离心后使用)作为3种微生物菌剂(利生源、酵之源、乳丁宝)的天然培养基,并将发酵物用于去除水产养殖尾水中的TN和NH3-N,以未投加发酵物的养殖尾水作对照组。对比发现,经离心柑汁发酵培养的利生源发酵物,对模拟尾水的净化效果最好,TN和NH3-N去除率分别可达到82.5%和98.7%,而对照组无去除效果。将该最优处理剂进一步用于去除草鱼和罗非鱼池塘尾水中的TN和NH3-N,发现去除速率均明显加快,其中罗非鱼池塘尾水的氮指标达到了淡水池塘养殖水排放要求(SC/T 9101—2007)二级标准。
TheXinhui citrus juice,as an agricultural waste,with or without centrifugation was taken as the culture medium for three kinds of microbial preparations(named Lishengyuan,Jiaozhiyuan,and Rudingbao),and the cultures were used for the removal of TN and NH3-N in aquaculture tail water.The tail water without culture addition was taken as control.After comparison,it showed that Lishengyuan culture with the uncentrifuged citrus juice had the best purification effect of the simulated tail water withremoval rates of 82.5%and 98.7%for TN and NH3-N respectively.The optimal Lishengyuan culture was further used to remove the TN and NH3-N in the tail water from thegrass carp pond and the tilapiapond,and it revealed that the removal efficiencies were improved,and the nitrogen index of the tail water from the tilapiapondhad achieved secondary standard of the requirement for water discharge from freshwater aquaculture pond(SC/T 9101-2007).
