工业废水

In this article,Canna,Cyperus and Penisetum were grown in artificial solution contained heavy metals such as lead and chromium to investigate their endurance to the two kinds of heavy metal.The experiment results showed that lead and chromium could decrease the height and biomass of plants even at low concentration of 2.0mg/L.

随着工业的迅速发展，各种工业废水和固体废弃物的渗出液直接排入水体，致使水体中重金属铅(Pb2+)和铬(Cr6+)等含量越来越高[1]，重金属不能像其他有机化合物那样可自然降解或生物降解，往往存在水体或沉积到水域底部或被水生植物浮游植物。

Decomposition of ultrasonic and its combined technologies are a rising sewage disposal technology,it has capacious prospect and implicational market.

1引言现代工业的快速发展和城市化的加速，产生了大量的工业废水和生活污水，导致水体的严重污染和水资源的短缺。

The properties of the zinc polysilicate flocculant and its application in the sugar industry,water treatment,industrial wastewater treatments are introduce

介绍了聚硅酸锌絮凝剂的性质及其在制糖工业、饮用水处理和工业废水处理等方面的应用。

Compared with other flocculants, the polymeric ferric sulfate has much better performance and characteristics, such as better adsorption, bridge erection, flocculation, floc formate fast, not easy to breaking, better repolymerization and weak corrosion. So it was widely used in the wastewater purification and treatment which contains industrial wastewater, urban sewage, water for industrial use and potable water etc.

与其它的絮凝剂相比较，聚合硫酸铁不但具有较强的吸附、架桥、絮凝沉淀性能，而且在水处理过程中有生成絮体速度快、絮体不易破碎、重聚性能好、腐蚀性小等特点，因此广泛用于工业废水、城市污水、工业用水以及生活饮用水等的净化处理。

Due to the industrial wastewater and life wastewater unconscionably emissions and agricultural pollution, water containing mud now not only sand, plants decay.

由于工业废水、生活废水无节制的排放及农业污染，现在的地表水不仅含有泥砂、动植物腐朽物。

This kind of highly concentrated organic industrial wastewater is hard to be biodegraded due to its complex component and high chroma.

焦化废水含有大量有机污染物和有毒无机物，成分复杂，污染物色度高，属较难生化降解的高浓度有机工业废水。

The water sample of this thesis is the coke plant wastewater from nanchang iron and steel company.

焦化废水是一种典型的含有难降解有机污染物的工业废水。

The advances in control and environmental risk management of industrial effluents and municipal sewage in developed countries and China are reviewed in the paper.

综述了国内外工业废水与城市综合废水的监控和环境风险管理进展。

Because the principle of the adsorption in removing heavy metals between aqueous and waste water. Therefor, the study of removing heavy metals in solution by actived carbon can help the treatment of removing the heavy metals in industry waste water and present a valuable reference for research on the disposing of metals in solution using actived carbon adsorption method.

活性炭吸附水溶液中的重金属离子与其吸附废水中的重金属离子的原理是相通的，所以对活性炭吸附溶液中重金属离子的研究有助于利用活性炭吸附技术处理工业废水，并为活性炭吸附溶液中的重金属离子方面的研究提供有益的参考。

Prednisone wastewater is one of the industrial wastewaters that is very difficult to be treated.

强的松生产废水是一种难处理工业废水。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
