【摘要】：稳定、多样的河湖水系生态系统恢复和维持难度大。针对北京典型再生水补水型河湖水体富营养化现象,选用火山岩、焦炭、沸石、陶粒、人工草等填料考察其对再生水补水型水体净化效果和物种的形成作用。结果表明:填充陶粒的反应器再生水出水各指标变化最为显著,其氮、磷等营养盐得到了较好地去除。火山岩、焦炭、沸石、陶粒和人工草5种填料附着细菌种属差异较小;附着浮游植物大多以硅藻门为主。5种填料反应器水体中的氮循环转化功能菌数量明显高于无填料反应器,其中陶粒反应器中数量最高,与水化学分析结果相吻合。陶粒对生境修复有着一定的促进作用。
[Abstract]:It is difficult to restore and maintain the ecosystem of stable and diverse rivers and lakes. Aiming at the eutrophication of typical reclaimed water in Beijing, volcanic rock, coke, zeolite and ceramsite are selected. The effects of artificial grass and other fillers on reclaimed water purification and species formation were investigated. Phosphorus and other nutrients were well removed. There was little difference between volcanic rock, coke, zeolite, ceramsite and artificial grass. Most of the attached phytoplankton was diatom phylum as the main filling reactor, the number of nitrogen cycling and transforming bacteria in the water body was significantly higher than that in the unpacked reactor, and the quantity of the ceramsite reactor was the highest. In accordance with the results of hydrochemical analysis, ceramsite plays an important role in habitat restoration.
