底部微孔增氧对池塘水体溶氧变化影响的研究

The Research of Influence on the Dissolved Oxygen Level by Micropore Tube Aerator on the Bottom of Fish Ponds

通过在水质和养殖条件基本相同的养鱼池塘,分别投放底部微孔增氧盘和叶轮增氧机,测量6月到9月中旬池塘溶氧量以及监测晴天24 h溶氧量,来研究底部微孔增氧方式对池塘溶氧分布和变化的影响。发现底部微孔增氧相对于叶轮增氧在提高池塘溶氧和改良底质条件两个方面有明显优势。

The variation of dissolved oxygen in cultural water which was increased oxygen by micropore tube aerator on the bottom and the impeller aerator on the surfaces was studied in this paper.The data of same water quality and breeding conditions of fish-ponds were detected,not only dissolved oxygen in pond water during June to the middle of September but also 24 hours oxygen on sunny days were detected.It turns out that there are more obvious advantages in improvement of dissolved oxygen and quality of the fish-ponds bottom conditions by the using of micropore aerator than impeller aerator.
