摘　　要：为了更经济、有效地处理猪场沼液,采用微藻净化沼液的方法,通过一株蛋白核小球藻(Chlorella pyrenoidosa)对10%猪场沼液稀释液为期18 d的净化,全面检测沼液在净化过程中不同时期、不同指标的变化情况。结果表明,蛋白核小球藻可在消毒后的沼液稀释液中存活且具有较好生长状态,OD_(680nm)最高可达1.206、相对生长速率最高可达0.208 0。经过蛋白核小球藻净化后,沼液中总氮、总磷、铵态氮含量去除率分别为61.89%、99.72%、96.79%;硝态氮以及亚硝态氮含量有所上升;COD含量变化曲线呈波动情况。证明了蛋白核小球藻净化猪场沼液的可行性。In order to treat biogas sluwy more economically and effectively, microalgae was used to purify biogas slurry. The aim was to fully detect the changes of biogas slurry at different times and different indexes during purifying 10% diluted biogas sluwy by a Chlorella pyrenoidosa for 18 days. The results showed that the algae chlorella pyrenoidosa could survive in the biogas slurry after disinfection and had a good growth status whose highest OD680nm could reach 1.206,highest relative growth rate could reach 0.208 0. The removal rates of total nitrogen,total phosphorus and ammonium nitrogen in biogas slurry were 61.89%,99.72% and 96.79%,respectively; The contents of NO3--N and NO2--N increased a little; And COD content showed a fluctuation curve. The feasibility of purifying the biogas slurrry by C. pyrenoidosa was proved.
