为研究基于生物絮团技术的碳源添加对池塘养殖水质的影响,分别在长春、沈阳、天津选取养殖水体中氨氮、亚硝酸盐氮浓度较高的池塘,实时测定水体中氨氮浓度,并按照公式计算出所需碳源(糖蜜)添加量,用养殖池塘水溶解均匀后全池泼洒。结果发现,添加碳源后,在长春养殖站,试验组氨氮有明显下降趋势,而对照组逐渐升高;在沈阳养殖站,实验组亚硝酸盐氮有下降趋势,但对照组缓慢升高,实验组的COD一直处于下降趋势,对照组COD先降低后升高;在天津养殖站,试验组氨氮有明显下降趋势,而对照组却一直升高。研究结果表明,向水体中添加碳源可以明显降低池塘水体中过高的氨氮,并对降低亚硝酸盐氮和COD有一定的作用。
為研究基于生物絮糰技術的碳源添加對池塘養殖水質的影響,分彆在長春、瀋暘、天津選取養殖水體中氨氮、亞硝痠鹽氮濃度較高的池塘,實時測定水體中氨氮濃度,併按照公式計算齣所需碳源(糖蜜)添加量,用養殖池塘水溶解均勻後全池潑灑。結果髮現,添加碳源後,在長春養殖站,試驗組氨氮有明顯下降趨勢,而對照組逐漸升高;在瀋暘養殖站,實驗組亞硝痠鹽氮有下降趨勢,但對照組緩慢升高,實驗組的COD一直處于下降趨勢,對照組COD先降低後升高;在天津養殖站,試驗組氨氮有明顯下降趨勢,而對照組卻一直升高。研究結果錶明,嚮水體中添加碳源可以明顯降低池塘水體中過高的氨氮,併對降低亞硝痠鹽氮和COD有一定的作用。

The higher concentration of ammonia nitrogen and nitrite nitrogen water of aquaculture ponds were selected to evaluate its effect on the pond aquaculture water quality by adding carbon resource in bio -flocs technology aquaculture system .The results found that with the carbon source added , in the Changchun experimental station, experimental group ammonia nitrogen significantly declined , while the control group increased;in the Shenyang experimental station,experimental group nitrite nitrogen and COD had a downward trend, but the control group increased slowly , while, the control group COD began to rise on August 17; in the Tianjin experimental station , test group had a obvious downward trend , but the control group increased constantly.The results showed that the adding of carbon resource can significantly reduce the high levels of ammonia nitrogen in the pond, and had a certain effect on reducing the concentration of nitrite nitrogen and COD.
