摘要: 为提高小球藻净化猪场废水的效果，在户外条件下系统比较了预处理方式、管道光反应器的种类和光径对蛋白核小球藻生长及其对猪场废水净化效果的影响。结果表明，猪场原废水COD、NH4+、PO43-、TN、TP含量分别为710、491、54、590和108 mg·L-1 时，蛋白核小球藻对经过3级过滤预处理后的猪场废水净化效果最好，其中脱色率及NH4+去除率分别高达88.56%和83.48%，显著高于对原废水的处理效果(P-1。采用直径为5 cm的立式光生物反应器培养蛋白核小球藻，通过循环采收，藻粉产量可达到0.93 g·L-1，其蛋白质含量最高达到58.9%，汞、砷、镉、铅含量分别小于0.1、1.0、0.5和4.0 mg·kg-1，符合《饲料用小球藻粉》(DB32/T 564-2010)标准。采收小球藻后的出水中，NH4+、PO43-、色度的去除率均高达90%以上，基本达到国家排放要求。该研究结果可为制定猪场废水的净化及蛋白核小球藻的工业化生产方案提供参考。
