将不同浓度的小球藻接种到草金鱼的养殖废水中，通过定期检测水体总氮、总磷、氨氮、亚硝酸氮、硝酸氮和高锰酸盐指数等水质指标，研究小球藻对养殖水体净化的能力。结果显示：小球藻能明显降低水体氮、磷等的含量，对氨氮的作用尤其显著；对硝酸氮吸收作用很小，长时间培养会引起高锰酸盐指数上升。小球藻净化水质的效果与水体中小球藻密度有关。
將不同濃度的小毬藻接種到草金魚的養殖廢水中，通過定期檢測水體總氮、總燐、氨氮、亞硝痠氮、硝痠氮和高錳痠鹽指數等水質指標，研究小毬藻對養殖水體淨化的能力。結果顯示：小毬藻能明顯降低水體氮、燐等的含量，對氨氮的作用尤其顯著；對硝痠氮吸收作用很小，長時間培養會引起高錳痠鹽指數上升。小毬藻淨化水質的效果與水體中小毬藻密度有關。

The effects of Chlorella vulgaris on the purification of grass goldfish aquaculture water were investigated outdoors with different microalgae density. The function parameters were measured including concentrations of TN, TP, NH4+-N, NO2--N, NO3--N and permanganate index. The results showed that C. vulgaris could effectively reduce nitrogen and phosphorus in the water, and NH4+-N reduction was especially significant. The absorption of NO3--N was small. Long time culture induced the increase of permanganate index. The purifying effect has certain relationship with C. vulgaris density.
