污水

This shows, as the addition of population, rich is used up accelerating growth, and the corporeal input quantity that the pollution of atmosphere and edaphic environment is quickening exasperate;(3) to create unit GDP and sendout (the wastage that includes water and sewage discharge capacity) all show descendent trend, the resource that reflects a system of our country economy uses efficiency to rise apparently.

由此可见，随着人口的增加，自然资源消耗在加速增长，而大气与土壤环境的污染在加速恶化；( 3)创造单位GDP的物质输入量和输出量(包括水的消耗量和污水排放量)均呈下降的趋势，反映出我国经济系统的资源利用效率明显提高。

Naphthalene cannot be detected in the roots, stems and leaves of eichhornia crassipes solms by using GC-MS.

采用GC-MS，在用於净化萘污水的凤眼莲根、茎叶中未检测到萘。

The technology of agriculture greenhouse could be used to prevent the damage from season shifting for Eichhornia crassipes solms in the process of removing naphthalene from aquatic solution.

所以，可认为在利用凤眼莲净化含萘污水时，采用农业温棚技术提高温度，以避免凤眼莲的生长受季节变化的影响。

Eichhornia crassipes and its root-zone microbes coordinated in pollution purification.

研究了凤眼莲净化污水时，根区微生物的动态变化。

The sludge settling characteristic is satisfying with SV varying from 22 to 30 and SVI varying from 58 to 80ml/g.The sludge bulking problem has been avoided successfully. The excess sludge can be thickened to 3%-4 %. The alkalinity remains equilibrious between the nitrification and denitrification in SBR-BAF system. The COD and TP loading of SBR are 2.08kgCOD/kgMLSS·d and 41.68gTP/kgMLSS·d, respectively. The NH4+-N loading of BAF is 1.16kgNH_4~+-N/m~3.d. The total HRT is about 10 hours which is only about half of suspended growth process for simultaneous phosphorous and nitrogen removal. Under the above mentioned high loadings and short HRT, the mean removal efficiency of COD, TP, NH4+-N, TN is 96%, 98%, 93%, and 84%, respectively. The mean effluent concentration of COD, TP, NH4+-N, TN, SS is 20mg/L, 0.23 mg/L, 3.24 mg/L, 7.68 mg/L, 5 mg/L respectively, which means every index can meet the first class of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.

最后，以上述最佳运行参数控制SBR-BAF系统运行，长期运行结果表明：系统中悬浮污泥的絮凝、沉降性能良好，SV值为22~30，SVI值为58~80，不再有污泥膨胀之虞，而且可以对剩余污泥进行重力浓缩，浓缩后污泥浓度可以达到3~4%；短程硝化和反硝化使得系统可以维持碱度平衡，无需额外补充碱度；系统在高负荷(SBR反应器COD负荷为2.08kgCOD/kgMLSS.d，TP负荷为41.68gTP/kgMLSS.d，BAF反应器NH4+-N负荷为1.16kgNH_4~+-N/m~3.d)、低水力停留时间(SBR反应器9h，BAF反应器1h，总计10h，约为同步脱氮除磷悬浮污泥工艺的一半)下稳定高效运行，对COD(不计BAF加入的外碳源)、TP、NH_4~+-N、TN的平均去除率为96%、98%、93%、84%，出水COD、TP、NH4+-N、TN、SS的平均浓度为20mg/L、0.23 mg/L、3.24 mg/L、7.68 mg/L、5 mg/L，各项水质指标均达到《城镇污水处理厂污染物排放标准》(GB 18918-2002 )一级标准的A标准的要求。

The method can be applied in the determination of the estrogenic compounds in wastewater samples successfully.

目标化合物的加标回收率为（94.0±2.9）%～（101±3.8）%，说明该方法能较好地应用于污水中雌激素化合物的定量检测。

This project is designed for the proper condition of the villages and towns , used to eliminate the sewage of living , waste water of production and the excrescent surface water. It can reduced spread of pathogen and environment pollution , in order to keep sanitation of the habitation.

项目简介：该项目是针对农村乡镇特有的生产和生活环境所设计，用于排除农村乡镇居民生活污水和生产中的各种废水、多余的地面水的工程，可有效减少病菌传播和对环境的污染，以保持生活环境的卫生。

Recently, with the Chengdu Institute of Biology, Chinese Academy of Sciences jointly develop new products "section Fasciola rotary" suspended filler has been applied for a patent on the product after the Chengdu Institute of Biology and Environmental Engineering Corporation, Beijing, great trial, are currently China's sewage treatment works best as a filler suspension is now mass production.

最近与中科院成都生物研究所共同开发了新产品&条片形旋转式&悬浮填料，现已申请专利，该产品经过成都生物研究所及北京市大有环境工程公司试用，是目前我国处理污水效果最佳的一种悬浮填料，现已批量生产。

The results of this study showed that the ability of the three aquatic plant species is more significantly to remove pollutants in summer and autumn, especially from June to September, is significantly superior to that in winter, the stage of aquatic plants grow more hearty is better than the stage plant grow more feeblish.

通过2006全年对成都活水公园人工湿地中三种优势挺水植物芦苇、香蒲、伞草所在塘床的进出水口的6个主要水质指标（pH 、DO、COD、BOD5、TP、TN）的逐月对比监测，探索不同植物种类对污水净化效率的影响。
