摘要
利用富营养化水体营养盐资源,以聚乙烯发泡板为人工浮床栽培绿萝、美人蕉和龟背竹,在生物填料表面生物膜的综合作用下,研究其净化景观水体的效果.经过60天的试验研究,结果表明,3种植物在实验水质条件下生长状况良好,可有效去除水中的氮磷及有机污染物,基本消除水体的富营养化,同时对城市景观水体具有美化作用.采用组合技术对水体中TN、NH3-N、TP、CODMn的去除率分别达到65.8%-84.4%、89.2%-97%、72.1%-92.9%和24%-50%,其中以龟背竹与生物接触氧化组合技术净化效果最好.
Eutrophication has become a serous problem for urban waters. Based on this situation, polyethylene cystose constructed floating beds were used to cultivate the Scindapsus aureus, Canna generalis and Monstera, under the comprehensive function of the bio-membrane formed on the surface of bio-medium, to improve water quality of scenic water bodies. The experiments were carried out for 60 days and the experimental results showed that the selected three plants grow well under the experimental conditions, and they could effectively remove ammonia-nitrogen, phosphorous and some organic pollutants. Meantime, the remediation system can beautify the urban scenic waters. The removal rates of TN, NHa-N, TP and CODM. respectively are 65.8% -84.4% ; 89.2% -97% ; 72.1% -92.9%and 24%-50% by using the combined technology. The system of Monstera combined with biological contact oxidation technique give the highest removal rate of the above pollutants.
