  • 摘要: 采用多级蚯蚓生态滤池对生活污水进行处理研究,考察多级蚯蚓生态滤池对污水中各类污染物的去除效果.试验结果表明,多级蚯蚓生态滤池连续运行80d,滤池对CODCr、NH4+-N和TP的去除效果良好,去除率分别为80.4%—98.6%、95.5%—99.5%和93.7%—99.7%,出水水质符合要求.但是滤池对TN去除效果不稳定,不加碳源TN去除率降低,最低为26.0%左右,添加碳源后TN去除率维持在60%左右.其中进水中C/N比为3.07,出水中一级滤池、二级滤池和三级滤池的C/N比分别为1.56、0.88和0.72,沿程水样C/N比呈逐级下降的趋势.运行22d后,在二级滤池出水中添加葡萄糖调节C/N比为3—6,总氮去除率上升.对TN去除研究分析,推断出碳源不足是TN去除率降低的重要原因.相比单级的蚯蚓生态滤池,多级蚯蚓生态滤池生活污水处理的更加彻底,应用前景更加广泛.
    Abstract: Under the condition of sewage treatment with the use of a multistage earthworm ecofilter, removal efficiencies of various pollutants were investigated. The results showed that in continuous operation for 80 days, the multistage earthworm ecofilter removal efficiency for CODCr,NH4+-N,TP was 80.4%—98.6%,95.5%—99.5%,93.7%—99.7% respectively, and the effluent quality met the national standards. However, removal efficiency of TN was unstable ranging from 26% to 60%. TN removal efficiency was as low as 26% without carbon source, bue could be maintained at 60% after addition of carbon source. C/N ratio decreased along the multistage earthworm ecofilter. The average ratio for the influent,first stage,second stage and third stage was 3.07,1.56,0.88,0.72, respectively. After 22 days operation, C/N ratio was adjusted to 3—6 by adding glucose, and TN removal efficiency reversed to increase slowly. It was postulated that lack of carbon source was the main reason for lowered TN removal efficiency. Compared to single-stage filter, multistage earthworm ecofilter basically meets the requirements of advanced treatment, and has a broad application prospect.
