摘要:
通过模拟实际封闭水域的室内水质净化装置,研究了水体生物与多孔混凝土的生态适应性以及形成的综合生态效应对水质的净化效果.多孔混凝土综合生态效应的水质净化效果可通过总磷(TP)、总氮(TN)、高锰酸盐指数(CODMn)和悬浮固体浓度(SS)的去除量进行评价.试验表明:附着生长在多孔混凝土上的黄花水龙、杂藻、螺蛳以及微生物形成一个完整的微生态系统,6周后可使水体中TP的去除率均达到95%,TN的去除率达72.5%,CODMn去除率达到75%.提出了多孔混凝土水质净化的机理,即多孔混凝土作的多孔结构为水体中的生物提供了附着生长的空间,为水体生物多样性的增加,生态系统的完善提供了一个基础平台,其形成的生态系统具有良好水质净化效果.
Abstract:
Results of the experiment on eco-environmental effect and water purification properties of porous concrete are reported. Equipments of the water purification experiment were designed to simulate natural water environment. Water purification of the porous concrete is evaluated by the removal amount of the total phosphorus(TP), total nitrogen(TN), the CODMn and suspended solids(SS). Integrated ecosystem is made up with jussiaea stipulacea ohwi, bellamya purificata, algae and microorganism which attached on the porous concrete surface and is able to remove 95% TP,75% TN and 75% CODMn. The water purification mechanism of porous concrete is that the porous structure of the porous concrete affords room for the integrated ecosystem and increases which varieties of water ecosystem, which purifies water efficiently.
