Method for treating breeding wastewater by utilizing chlorella

The invention discloses a method for treating breeding wastewater by utilizing chlorella. The method comprises the following steps: adding chlorella and zeolite powder into the breeding wastewater to remove COD (Chemical Oxygen Demand). The zeolite powder is added into the breeding wastewater, the zeolite powder is used for adsorbing and fixing the chlorella, the chlorella grows on the surface of the zeolite powder, the zeolite powder is used for limiting the activity range of paramecia and weakening the influence of the paramecia on the normal growth process of the chlorella, and therefore the chlorella can always keep the high COD removal capacity, and the yield of the chlorella is improved. Meanwhile, the problem of subsequent chlorella removal is solved, the difficulty of advanced treatment of the aquaculture wastewater is reduced, and the method has the advantages of being easy to operate, environmentally friendly, low in cost and the like. 本发明公开了一种利用小球藻处理养殖废水的方法，其包括以下步骤：将小球藻和沸石粉末加入养殖废水中进行COD去除。本发明通过在养殖废
