在石菖蒲克藻研究的基础上,在室内进行模拟试验,从青山湖排污口取污水置于培养缸中,培养石菖蒲。在培养前后定期进行水质成分分析,测试氯化物,有机耗氧量(COD),生化需氧量(BODs),溶解氧(DO),铵氮和总磷的变化,植株总氮、总磷的变化,再分析石菖蒲对污水的净化效果,发现氯化物、COD、BOD5和铵氮呈下降趋势,幅度均较大;DO则呈上升趋势,通过本试验发现水体总氮去除率达874%,总磷去除率达439%,溶解氧(DO)增加266%,证明石菖蒲对富营养化水体的净化能力是很强的。因此,用石菖蒲治理此水域,可同时达到绿化水面、美化环境、净化水质的功效。
On the basis of the research on Acorus calamus, we conducted a simulation experiment indoors and took Sewage from the Qingshan Lake outfall to place it in a culture tank to cultivate Acorus gramineus. Before and after the cultivation, the water quality analysis was carried out on a regular basis. Chloride, organic carbon (COD), BODs, dissolved oxygen (DO), ammonium and total phosphorus, total nitrogen and total phosphorus The results showed that chloride, COD, BOD5 and ammonium nitrogen showed a decreasing trend with larger amplitude and DO increasing trend. The total nitrogen removal rate of water body was 874 %, Total phosphorus removal rate of 43 9%, dissolved oxygen (DO) increased by 26 6%, to prove the Acorus calamus purification ability of eutrophic water is very strong. Therefore, the use of Acorus calamus to control this water can simultaneously achieve the green water, landscaping, water purification effect.
