藻液浓缩方法的改进与浓缩过程水体性质特征

为制作生物燃油提出了一种藻液浓缩方法。对湖泊水华过程生成的藻液进行浓缩研究,浓缩过程表明:在温度为21.5~22.9℃时,沉降装置上清液的理化性质为:溶解氧浓度为19.91~4.39 mg/L,p H为9.98~10.54,电导率为1 321~1 459μS/cm,氧化还原电位为-23.6~113.1 m V,浓缩倍数为26.58~28.95倍。藻液初始浓度为0.94 g/L,沉降后的高浓度藻液干重均值为25.47 g/L。结果显示:沉降系统能长时间保持稳定,适宜藻液长期浓缩。

THE IMPROVEMENT OF ALGAE CONCENTRATION METHOD AND THE WATER CHARACTERISTICS DURING THE ENRICHMENT PROCESS

A method for concentrating algae solution was introduced for the production of biofuels． Algae solution in the water bloom course was concentrated． Enrichment process indicates that: When the temperature was in the range of 21. 5 ～ 22. 9 ℃， the dissolved oxygen in the supernatant was in the range of 19. 91 ～ 4. 39 mg /L; pH was in the range of 9. 98 ～ 10. 54; the conductivity was in the range of 1 321 ～ 1 459 μS /cm; the oxidation-reduction potential was in the range of － 23. 6 ～ 113. 1 mV; the concentration mutiple was in the range of 26. 58 ～ 28. 95． When the initial concentration of algae was 0. 94 g / L，the mean dry weight of algae solution was 25. 47 g /L after concentration． The conclusion was that the settlement system ran stable for a long time and was suitable for the concentration of algae．
