摘　　要：用普通小球藻Chlorella vulgaris C9-JN2010处理氨基酸工业废水,实现废水无害化利用。在微型鼓泡式光反应器中,(25±1)℃,pH(6.5±0.5),0.1 vvm空气流速,4 000 lux,16 h:8 h光暗比条件下,分别考察小球藻在体积分数为20%、40%、60%、80%及100%的氨基酸废水中培养生物量变化及TN、TP、COD的去除率。结果表明,体积分数40%氨基酸废水处理效果最好,停留时间3～4 d,藻细胞干重、比生长速率和最大生产强度分别为0.731 g/L、0.565 d-1、0.243 g/(L.d);废水中TN、TP及COD的去除率分别为92.0%、98.0%及80.0%,对应去除强度分别为30.7、3.28、133.3mg/(L.d)。利用小球藻可以较彻底的去除氨基酸废水中氮、磷及COD等营养,达到污水处理效果。This research was to treat amino acid wastewater by chlorella vulgaris C9-JN2010 and to achieve the use of waste water harmless.Therefore,feasibility of microalgae culture of chlorella vulgaris was studied the in bubbled column photo-bioreactor with different content amino acid wastewater medium,which the photo-bioreactor was illuminated at 4 000 lux（Light-dark cycle is16 h：8 h） and air flow was 0.1vvm.The algae inoculums were cultivated at（25±1）℃ and pH（6.5±0.5）.Results were as follows： different content amino acid wastewaters had significant effects on chlorella vulgaris,at optimum 40% wastewater medium,which its biomass yield,special growth rate and production intensity were 0.731 g/L,0.565 d^-1 and 0.243 g/（L·d） respectively;there were hardly total nitrogen and phosphorus residues in culture medium after three or four days culturing,which removal of total nitrogen,phosphorus and COD were 92.0%,98.0% and 80.0% and their removal intensities were 30.7,3.28 and 133.3 mg/（L·d） respectively.Therefore,nutrition of N,P and COD form amino acid wastewater was thoroughly removed to treat wastewater successfully.
