摘　　要：目的探究在地下水源热泵回灌过程中铁细菌的存在对铁锰引起的生物化学行为的影响,进一步发现铁细菌与不同质量浓度的铁锰离子的反应情况,提供解决生化复合堵塞问题的方案.方法以有无铁细菌的含相同质量浓度铁锰回灌水试样进行试验对比,分析铁细菌存在对生化复合堵塞是否有加剧效果,另进一步设置不同质量浓度的铁锰回灌水进行对比试验,观察铁细菌对铁锰离子各自的氧化程度.结果铁细菌的存在明显加剧了纯化学堵塞,随着二价铁离子质量浓度增加,氧化现象更为剧烈,堵塞时间明显提前,而锰离子质量浓度并未过多影响整个生化复合堵塞.结论在地下水源热泵工程中,降低回灌水中铁离子的质量浓度,可以有效防治地下水中铁锰离子质量浓度较高的地区水源热泵回灌堵塞问题.The iron-manganese-induced biochemical behavior of iron bacteria in the process of recharge of groundwater source heat pump was explored to find out the reaction of iron bacteria and iron-manganese ions with different mass concentration and provide a solution to the biochemical complex plugging problem.The effect of iron bacteria on biochemical complex plug was analyzed to set contrast test with different concentrations of iron manganese backwash water to observe the oxidation degree of iron and manganese ion by iron bacteria.The results showed that the presence of iron bacteria significantly aggravated the pure chemical blockage.With the increase of ferrous ion concentration,the oxidation phenomenon was more severe and the blocking time was earlier.However,the mass concentration of manganese ion did not affect the whole biochemical complex blockage too much.In underground water source heat pump project,reducing the mass concentration of iron ions in the recharge water can effectively prevent and control the rechargeable clogging of water source heat pump where the concentration of iron and manganese ions is high in the groundwater.
