中文摘要：

【目的】磷化氢为磷的气态形式,将污水中磷通过转化为磷化氢的方式去除,为污水除磷提供新思路。【方法】采用厌氧持续培养的方式,以经过磷化氢处理和没有处理的水稻土分别作为接种物,在氧化还原电位（ORP）≤-300 m V、恒温35°C,避光持续培养160 d。【结果】培养器1出水总磷的去除率稳定达到25%,最高去除率为26.78%,气体磷化氢的产量达到130 ng/L以上。培养器2出水总磷去除达到23%,气体磷化氢的产量达到126 ng/L。【结论】对水稻土进行厌氧条件下连续培养,可以形成稳定的厌氧产磷化氢微生物体系,提高磷化氢的释放量。

英文摘要：

[Objective] Conversion of phosphorus to phosphine, a gaseous form of phosphorus, has the potential to remove phosphorus from wastewater. [Methodsl Incubator was kept anaerobically for 160 days, with paddy soil as inoculum that was treated either with phosphine without phosphine, under the condition ORP≤-300 mV, 35 ℃ and in dark. [Results] In incubator 1, total phosphorus removal in the effluent reached 25%, with the highest rate of 26.8%, and the gas phosphine output was abovel30 ng/L; and in incubator 2, total phosphorus removal in the effluent reached 23% with gas phosphine output of 126 ng/L. [Conclusion] Microorganisms from paddy soil can form a stable system to produce phosphine from phosphorus under anaerobic conditions to remove phosphorus contamination in soils.
