  • 摘要: 以天然矿物质沸石、细砂及煤渣取代传统滤料构建复合基质生态床，表面种植景观植物，采用下向流-上向流运行方式修复北方景观水体。分别进行静态实验及不同循环速率下的动态实验，考察对水体污染物去除过程。结果表明，2种运行方式下对水体NH+4-N去除率都在85%以上，其中以1 h为循环周期的运行方式去除率达97%，较静态提高12.8%；TN去除率最高为84%；TP去除不稳定，过程缓慢。煤渣层对NH+4-N的去除效果差，硝化作用不彻底与反硝化作用的加强使下层出水NH+4-N 、NO-2-N及NO-3-N浓度均高于上层。提高循环速率有利于对氮的去除。
    Abstract: Natural zeolite, silver sand and coal cinder were chosen instead of traditional filling to construct ecological filter with plant on surface. Its running mode was upward combining with downwards flow to bio-remedy static lake water in Northern China. Static and dynamic experiments were carried respectively to study remediation efficiency. Effluent was recycled at different periods in dynamic parts. Data showed that removal rates of ammonia nitrogen (NH+4-N) were all higher than 85% in each pattern. The best removal rate reached 97% at recycling period of 1 h, it was 12.8 percents higher than that of static pattern; removal rate of total nitrogen (TN) could reach 84%. TP removal was slow and unstable. Coal cinder have low capacity to remove NH+4-N, halfway nitrification and denitrification made NH+4-N ,NO-2-N and NO-3-N concentration of effluent from under-layer higher than up-layer. Improving recycling rate could promote removal of nitrogen.

摘要: 以天然矿物质沸石、细砂及煤渣取代传统滤料构建复合基质生态床，表面种植景观植物，采用下向流-上向流运行方式修复北方景观水体。分别进行静态实验及不同循环速率下的动态实验，考察对水体污染物去除过程。结果表明，2种运行方式下对水体NH+4-N去除率都在85%以上，其中以1 h为循环周期的运行方式去除率达97%，较静态提高12.8%；TN去除率最高为84%；TP去除不稳定，过程缓慢。煤渣层对NH+4-N的去除效果差，硝化作用不彻底与反硝化作用的加强使下层出水NH+4-N 、NO-2-N及NO-3-N浓度均高于上层。提高循环速率有利于对氮的去除。
