High Rate Algal Ponds (HRAP) were operated at pilot scale to investigate the performance of HRAP under the temperate climate conditions of Shanghai, China. The results indicated that the HRAP gave good efficiency for nutrient removal, especially during summer. With a retention time of 4 or 8d according to the season, the annual average removal efficiencies for COD, NH4-N and PO4-P were 50%, 87% and 40%, respectively. The multi-factor linear models showed the relationships between nutrient removal efficiency and influencing factors. Using a macrophyte pond to separate algae from HRAP can achieve concentrations of COD, TP and TKN in the effluent at around 50 mg/L, 1.5 mg/L and 5 mg/L respectively.
在中试规模下运行了高负荷藻类塘(HRAP),以研究其在中国上海温带气候条件下的性能。结果表明,HRAP对营养物的去除效率良好,尤其是在夏季。根据季节,停留时间为4天或8天,COD、NH4-N和PO4-P的年平均去除效率分别为50%、87%和40%。多因素线性模型显示了营养物去除效率与影响因素之间的关系。使用大型植物塘将藻类与HRAP分离,可以使出水的COD、TP和TKN浓度分别达到约50mg/L、1.5mg/L和5mg/L。
