This paper proposes the use of hydrogen oxidizing bacteria (HOB) for the removal of orthophosphate from surface water as treatment step to prevent cyanobacterial blooms. To be effective as an orthophosphate removal strategy, an efficient transfer of hydrogen to the HOB is essential. A trickling filter was selected for this purpose. Using this system, a removal rate of 11.32 ± 0.43 mg PO-P/L.d was achieved. The HOB biomass, developed on the trickling filter, is composed of 1.25% phosphorus on dry matter, which suggests that the orthophosphate removal principle is based on HOB growth. Cyanobacterial growth assays of the untreated and treated water showed that Synechocystis sp was only able to grow in the untreated water. Orthophosphate was removed to average residual values of 0.008 mg/L. In this proof of principle study, it is shown that HOB are able to remove orthophosphate from water to concentrations that prevent cyanobacterial growth.
本文提出使用氢氧化菌（HOB）去除地表水的正磷酸盐，作为防止蓝藻水华的处理步骤。为了成为一种有效的正磷酸盐去除策略，将氢有效地转移到 HOB 至关重要。为此选择了滴滤器。使用该系统，实现了 11.32 ± 0.43 mg PO-P/L.d 的去除率。在滴滤器上形成的 HOB 生物量中含有 1.25%的干物质磷，这表明正磷酸盐去除的原理基于 HOB 的生长。未处理和处理水的蓝藻生长试验表明，Synechocystis sp. 只能在未处理水中生长。正磷酸盐被去除到平均残余值为 0.008 mg/L。在这项原理验证研究中，证明了 HOB 能够将水中的正磷酸盐去除到防止蓝藻生长的浓度。
