摘　　要：利用自制实验装置模拟开放跑道池式培养方式,采用预处理过的乳制品厂污水为培养基,在流动状态下,研究了不同培养液含量和不同流速条件下对螺旋藻养殖的影响。结果表明,乳制品厂污水经过简单的处理可以用于螺旋藻的培养,在污水稀释率为1d的情况下,螺旋藻可以良好的生长并可以获得一定的产量。最高密度达到3.0g·L-1(湿重),氮的去除率在85%左右,磷的去除率在50%以上。污水养殖螺旋藻的品质基本达到国家标准。Cultivating Spirulina platensis with pretreated dairy effluent under continuous flowing culture condition using modified open raceway pond was studied. The results illustrated that the wastewater was suitable to be used as culture medium of Spirulina. When dilution rate was 1d, the alga could grow well inpretreated dairy effluent, and a high biomass was obtained and the nutrient in the wastewater was efficiently removed. The highest density of algae was nearly 3.0g·L-1(wet weight),the removal rate of nitrogen was about 85%,while phosphorus was more than 50%. The quality of Spirulina cultivated in wastewater reached the national hygiene standard of Spirulina with fair grade.
