论文摘要
这项研究的目的是评估主要治疗方法对处理城市废水的两个试验尺度高率藻类池塘（HRAP）的效果，考虑到它们的治疗效率，生物量生产率，特征和沼气生产潜力。结果表明，初级治疗并未显着影响废水处理效率（NH4+-N的去除93和91％，COD去除62％和65％的HRAP，分别有和没有初级治疗）。未经初级治疗的HRAP具有更高的生物多样性和生产率（18 vs. 16 g VSS/M2D）。来自两个系统的生物量都呈现出良好的结算能力。生化甲烷电位测试的结果表明，与微藻单数消化相比，共消化的微藻和原发性污泥导致更高的甲烷产量（238-258 mL CH4/g VS）（189-225 ml CH4/g VS）。总体而言，接受和不接受初级治疗的人力制剂似乎是将废水处理和生物能源恢复相结合的合适替代方法。
The aim of this study was to assess the effect of primary treatment on the performance of two pilot-scale high rate algal ponds (HRAPs) treating urban wastewater, considering their treatment efficiency, biomass productivity, characteristics and biogas production potential. Results indicated that the primary treatment did not significantly affect the wastewater treatment efficiency (NH4+-N removal of 93 and 91% and COD removal of 62 and 65% in HRAP with and without primary treatment, respectively). The HRAP without primary treatment had higher biodiversity and productivity (18 vs. 16 g VSS/m2d). Biomass from both systems presented good settling capacity. Results of biochemical methane potential test showed that co-digesting microalgae and primary sludge led to higher methane yields (238 - 258 mL CH4/g VS) compared with microalgae mono-digestion (189 - 225 mL CH4/g VS). Overall, HRAPs with and without primary treatment seem to be appropriate alternatives for combining wastewater treatment and bioenergy recovery.
