Both Cd2+ and Cr6+ destroyed Pistia stratiotes and Myriophyllum spicatum in the polluted solution,and Myriophyllum spicatum resisted Cd2+ and Cr6+ stronger than Pistia stratiotes,but Pistia stratiotes resumes more quickly than Myriophyllum spicatum.So in order to achieve better effects Pistia stratiotes and Myriophyllum spicatum should be planted mixed.

Cd2+和Cr6+对大薸和穗状狐尾藻都产生了不同的毒害作用，而穗状狐尾藻的耐Cd2+和Cr6+的能力要强于大薸，但穗状狐尾藻的自身恢复能力要小于大薸，因此为了达到更好的净水效果，大薸和穗状狐尾藻应混合种植。

Nitrophenol is a commonly occurring industrial pollutant, which has been found to affect our environment, causing ecological imbalance. Biodegradation is a useful strategy to detoxify wastewater and polluted environment, which is the best choice of the nitrophenol contaminated soil remediation.

硝基酚为工业上常见的污染物之一，对环境造成重大之冲击，生物降解因具高之经济效益，且可用於去除受污染的环境，故可做为土壤硝基酚污染整治的最佳选择之一。

In our work, Activated Carbon and Bentonite are selected as adsorbents in this process to degrade nitrophenol wastewater and slightly-polluted potable water. This paper investigates operation parameters; reaction mechanism; carbon modification and reaction kinetic model.

本文分别采用活性炭和膨润土作为吸附剂，以硝基酚污染物和低浓度微污染源水为处理对象，对该体系的工艺参数、反应机理、吸附剂改性、有机污染物降解途径以及反应动力学模型等方面进行了系统的研究。

We carried out a serial of experiments for 30 newly-fit houses in Northest Normal Univercity during a period from 2005 August to2006 February in terms of indoor formaldehyde concentration by means ofinvestigation, sampling, analysis and monitoring, track check especially madefor tensely polluted houses and research and analysis have been done basedon the results.

其中甲醛是装修后的建筑室内空气中常见的污染物之一，用做室内装饰的胶合板、细木工板、中密度纤维板和刨花板等人造板材中都含有甲醛，即使长期接触低剂量的甲醛也会引起慢性呼吸道疾病，高浓度的甲醛对神经系统、肝脏等都有毒害，长期接触较高浓度的甲醛会出现急性精神抑郁症，国际癌症研究所已将其作为可致癌物对待。

As a result, Oenanthe javanica is an economical and effective biological material for purification of heavily polluted river courses in winter-spring.

水芹菜是冬－春季节净化重污染河道的经济有效的生物材料。

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。

The dynamic simulation test showed that, the removal rate of TN、 NH_3-N、TP of Oenanthe javanica floating-bed was positive correlated with water temperature. The average removal loading rate of TN and TP were 0.80g/m.~2·d and 0.11g/m~2·d, respectively. The inhibition on algae was steady and the average inhibition rate was 57.3%. We also got the best value of hydraulic loading rate, floating-bed coverage rate, water depth under dynamic polluted river. They were 1.0m~3/(m~2·d)、 30%、 30cm.

动态模拟试验表明：水芹菜浮床对动态污染河水中TN、NH_3-N、TP的去除率与水温正相关，TN的平均去除负荷为0.80g/m~2·d，TP的平均去除负荷为0.11g/m2~2·d，对藻类的抑制作用较为稳定，平均抑制率为57.3%；获得了对动态污染河水最佳净化效果时的水力负荷参数为1.0m~3/(m~2·d)、浮床覆盖率为30%、水深为30cm。
