摘要: 选择花岗岩块石、卵石和废建筑砌块3种材料作为格宾填料，研究不同填料在模拟河道中对河水水质净化效果的影响。结果表明，随着实验装置运行时间的延长，各填料对N、P营养盐及有机物的去除能力均有不同程度的提高；3种填料中，卵石相较于其他2种填料对NH3-N、TOC和DOC的去除能力保持在较高的水平，运行26 d后分别达65.26%、71.06%和78.06%；3种填料在实验装置运行初期对TP都有较好的去除效果，运行12 d后，花岗岩块石、卵石、废建筑砌块对TP的去除率分别达89.20%、91.05%和94.71%；卵石表面附着的微生物脂磷含量及脱氢酶活性分别为53.43 nmol P/cm3、10.67 μg TF/（h·cm3），均显著高于其他两种填料（p<0.05），其表面较高的微生物量及酶活性有利于对氮素及有机物的去除。

Abstract: The study investigated the effect of three substrates (granite rubble， gravel and waste building blocks) on river self-purification in Gabion revetment. The removal rates of nutrients (NH3-N and TP) and organic compounds by all the substrates increased with the operation time of the test equipment. NH3-N and organic compounds removal rate by gravel maintained at a highe level. The removal rates of NH3-N，TOC and DOC were up to 65.26%，71.06% and 78.06%， respectively after operating for 26 days. The removal rate of TP by granite rubble， gravel and waste building blocks reached 89.20%， 91.05% and 94.71%， respectively after operating for 12 days. Lipid phosphorus content and dehydrogenase activity (DHA) of the microbial film by gravel were 53.43 nmol P/cm3 and 10.67 μg TF/（h·cm3）， respectively， which were significantly higher than the other two substrates (p<0.05). The highe biomass and enzyme activity enhanced removal efficiency of nitrogen and organic compounds.
