摘要
设计了5个规模相同厌氧发酵小试试验装置，进行为期8个月的最佳肥效试验研究。动态对比试验研究结果表明，藻浆厌氧发酵作为有机肥肥效最佳运行条件包括藻浆上浮比为100％、发酵温度为24℃、pH为7．0-8．0等。接种厌氧发酵藻泥对藻浆厌氧发酵肥效无显著性影响，但可大大加快藻浆厌氧发酵的速率。接种厌氧发酵藻泥量与藻浆量比为1：10时，可将藻浆厌氧发酵时间缩短至7d。在上述试验条件下，经过7d的厌氧发酵，藻浆滤后液体中氨氮、有效磷质量浓度至少可达1028，186mg／L。
To investigate the operation parameters of algae paste anaerobic fermentation with optimal fer- tilizer effectiveness, five laboratory-scale reactors were designed to treat algae paste. The results of the 8- month trial for optimal fertilizer effectiveness indicated that the optimal fertilizer effectiveness would be re- alized with the floating ratio of 100%, temperature of 24 ℃ and pH of 7.0-8.0. The inoculation fer- mentation algae sludge had significant effect on anaerobic fermentation speed, but not on fertilizer effec- tiveness. Under the condition that fermentation algae sludge was inoculated into reactor at inoculation fer- mentation algae sludge rate being 1 ： 10, the anaerobic fermentation duration was shortened to 7 d. Under these conditions, the NH4 - N and available phosphorus concentrations in algae liquid filtered from algae sludge were at least 1 028 mg/L and 186 mg/L when the anaerobic fermentation lasted 7 d.
