The results showed that all the four macrophytes had abilities to resist hydraulic impact loading, and were adapted to the dynamic instability of quality and quantity of inflow water. All the plants could decontaminate COD, NH3-N, NO3-N, TN and TP in the sewage with different efficiency, in which Oenanthe javanica and Myriophyllum verticillatum L. had the best comprehensive purification ability.

结果表明：4种植物都具有一定的抗水力冲击负荷能力，能适应河道污水水质和水量均不稳定的动态变化特征，并对污水中COD、NH3-N、NO3-N、TN和TP等指标均有去除作用；但各种植物对不同指标的去除能力有较大差异，其中浮水植物水芹菜和沉水植物狐尾藻综合净化效能较强。

Oenanthe javanica was satisfied the requirements. In a low temperature of 10~15 ℃, Oenanthe javanica was used to static purify the nitrogen and phosphate in the simulative aquaculture wastewater.

结果表明，在10℃~15 ℃低温条件下，水芹对水体中的氨氮和磷酸盐具强烈吸收作用。4 d中，水芹对3组不同质量浓度污水中氨氮和磷酸盐的去除率分别为：A组79.5%和31.9%，B组82.6%和48.8%，C组99.1%和72.7%。

Some conclusions were drawn: Oenanthe javanica grew normally when TN and TP concentrations in raw water were 7.05-9.99 mg/L and 0.29-0.73 mg/L respectively; with the hydraulic load being 0.5 m^3/(m^2d), the removal rates of NH3-N, TP, and TN from heavily polluted river water by Oenanthe javanica floating bed were positively related to water temperature, and it inhibited the growth of algae stably; the mean removal rate of nutritive salt increased with the concentration of raw water.

研究结果表明，进水ρ和ρ分别为7.05~9.99mg/L和0.29~0.73mg/L，水芹菜能正常生长，在水力负荷为0.5立方公尺/的条件下，水芹菜浮床对重污染河水中的NH3-N，TP，TN的去除率与水温正相关，对藻类的抑制作用稳定；营养盐的去除负荷随原水质量浓度的增加而增大。

Based on the national tenth five magnitude project — Suzhou City Water Environment Improvement and Synthesize Demonstration item, we carried out the static simulation test and the dynamic simulation test under the condition of heavy pollution loading rate and low transparency and dissolved oxygen in polluted river of suzhou ancient city district. These investigations were on the base of the formers' work. We analyzed the purification effects and rules of plant floating-bed technology on polluted river water, and also applied the technology to purify the polluted river water in Miaojia River. Conclusions were summed up in the following:The dominance plant option test was carried out among Oenanthe javanica, Lolium mutliflorum and Allium sativum under low temperature condition. The results showed that the Oenanthe javanica was the dominance floating-bed plant under low temperature condition. Its net removal rate of TN、 NH_3-N、 TP、 COD_ were 51.3%、 65.2%、 55.6%、 57.6%, respectively, and inhibition rate of algae reached 92.3%.

本论文以国家863重大科技专项——&苏州市城市水环境质量改善与综合示范&项目为依托，在前人研究的基础上，根据苏州古城区污染河道污染负荷重、透明度及溶解氧低的实际情况，通过静态、动态模拟试验，研究了植物浮床技术对污染河水的净化效果及规律，同时在苏州古城区内的苗家河开展了植物浮床技术净化污染河水的示范应用，得出了以下结论：(1)低温条件下对水芹菜、多花黑麦草、大蒜三种浮床植物筛选的试验表明：水芹菜是低温条件下浮床植物的优势种，其对TN、NH_3-N、TP、COD_的净去除率分别为51.3%、65.2%、55.6%、57.6%，对藻类的抑制率达92.3%。
