摘 要：
酿醋废水经水解酸化预处理后,在柱式光生物反应器中利用不同体积分数的水解酸化液流出物进行了小球藻培养实验。研究表明酿醋废水经水解酸化处理后COD、氨氮、总磷、挥发性脂肪酸均有不同程度的减少,其中COD、总磷含量分别减少了61.8%、63.6%,挥发性脂肪酸成分变化幅度较大。当酿醋废水水解酸化流出物体积分数高于40%,小球藻生长明显受到抑制,10%~30%体积分数的水解酸化流出物培养的小球藻生长较好,藻细胞浓度可达6.6×107个/m L,并且流出物添加磷酸盐后,小球藻在低体积分数废水流出物生长没有延滞现象。培养7 d后,小球藻对酿醋废水水解酸化流出物的净化效果显著,氨氮、总磷几乎全部去除,添磷条件下废水流出物COD降低达96.6%。小球藻在体积分数为30%的水解酸化流出物生长含油量最高为24%,C16-C18的脂肪酸含量在83.0%~95.5%之间,该小球藻具备一定的生物柴油开发潜力。

摘 要：
After the hydrolysis acidification of vinegar fermentation wastewater, the cultivation of Chlorella sp. and nutrients removal in different concentration hydrolyzates of vinegar fermentation wastewater were investigated in the vertical tubular photobioreactor. Results showed that after the hydrolysis acidification of vinegar fermentation wastewater,the removal rates of COD,ammonia,volatile fatty acids( VFAs) and total phosphorus( TP) were all decreased to some extent. The removal rates of COD and TP were 61. 8% and 63. 6%, respectively. The components of VFAs were changed significantly. When the volume fraction of hydrolyzate was more than 40%,the growth rate of Chlorella sp. was inhibited. When the volume fraction of hydrolyzate was between 10% and 30%,the growth rate of Chlorella sp. was good. The concentration of Chlorella sp. cell could achieve 6. 6 × 107 cells / m L. The growth curves of Chlorella sp. were no lag phase,after the addition of phosphate in the hydrolyzate of vinegar fermentation wastewater. After 7 d cultivation,the ammonia and total phosphorus were almost completely removed. The 96. 6% COD removal was achieved after addition of some phosphate. The oilcontent( 24%) was observed using 30% volume fraction hydrolyzate of vinegar fermentation wastewater.The contents of fatty acids C16-C18 were between 83. 0% and 95. 5%,which had good potential for the development for biodiesel utilization.
