Nonuniformly mixed pollutants----For these pollutants, the damage they cause is a function not only of the amount of emissions, but also the location of the emissions sources.

非统一混合污染物——对于这些污染物，他们产生的损害不仅仅是排放总量所造成的，同样是排放源造成的。

There are two major ways for government to regulate the environmental pollution of companies. One is by legislative means which use law to obligatorily and directly control the treatment and discharge of pollutants. The other is by economic means which use subsidies, taxations, charge and emission trading to indirectly control the treatment and discharge of pollutants.

政府机构对企业环境污染进行管制的手段主要有两个：一是借助于法律手段，以立法的形式对企业污染物处理及排放进行强制性的直接管制；二是借助于经济手段，用补贴、征税、收费和排放权交易制度等形式对企业污染物处理及排放进行的间接管制。

The new opinion and mechanism that the simultaneously adsorption of complex pollution of both organic and heavy metals will be achieved on soil modified with amphoteric surface modifying agent, which have both charged group and organophilic group on one ASMA molecule, were proposed at first time, and its rationality was testified at the same time; The 50% was the critical CTMAB modifying ratio of soil CEC at which the organophilic bond modifying mechanism was emerged; The thermodynamic characteristics of adsorption of OPT and HMP on OMS were discovered ; The study revealed the surface peculiarity of OMS that the modifying agent were distributed at uneven scatter mode and multi-characters surface were coexisted on surface of OMS, revealed the adsorption peculiarity of OMS that multi-mechanisms were coexisted, confirmed the unequal charge amount modifying mode of OMS in which dual-modifying mechanism of both ion exchange and OPB were processed at the same time, and confirmed that the adsorption hobby to CTMAB was higher than that to Ca2+ on Lou soil.

首次提出了用两性表面修饰剂对土壤进行修饰改性，利用两性表面修饰剂所具有的荷电基团和疏水基团达到对土壤中有机、重金属污染物同时吸附的思路和机理，并通过实验证实了所提设想的合理性；发现了土壤CEC值的50%修饰比例是CTMAB开始显现以疏水键机制对土土样表面进行修饰的临界点；揭示了有机修饰改性土对有机物、重金属吸附过程的热力学特征，填补了该项研究工作的空白；阐明了修饰剂在改性土表面呈分散态的非均匀分布，改性土表面具有不同性质表面共存的表面特征和对污染物多机制共存的吸附特征，确定了阳离子表面修饰剂在土表面的修饰是一种离子交换和疏水键结合两种机制相伴并行且为非等电荷量交换的修饰反应模式，以及土具有对CTMAB的吸附偏好性远大于对钙离子吸附偏好性的特征。

Some contaminant invade human body through several mediums like air, water, food chain, sometimes large quantity of several contaminants invade simultaneously, thus causing peracute danger.

有的污染物在短期内通过空气、水、食物链等多种介质侵入人体，或几种污染物联合大量侵入人体，造成急性危害。

The main pollutants from this chemical plant is perchloroethane, pentachloroethane, hexachlorobutadiene and HCB, and such pollutants are present in the soil with high densities, some as high as 1%- 95%, of which the perchloroethane is near the purity of the corresponding product, and especially this part of the soil contains comparatively high-density persistent organic pollutant HCB, which makes it suitable to be disposed of together with other soils. Therefore it is suggest that this part of soil should be separately dug out and transported outside of the site.

化工厂的主要污染物质是六氯乙烷、五氯乙烷、六氯丁二烯和六氯苯，土壤中上述污染物的浓度非常高，有些达到1%至95%，其中六氯乙烷接近相应的产品的纯度，特别是这一部分含有较高浓度的持久性有机污染物六氯苯，不利于与其它土壤混合处理，建议将这一部分单独开挖出来并运出场外。

Some reports show that photocatalytis has great potential in dealing with poisonous and pollute substances using semiconductor nanomaterials as photocatalyzer.

近年来随着工业废气、废水、农业农药等污染物剧增，环境污染问题日趋严重，研究表明，光催化技术在环境污染物治理方面有着良好的应用前景。

A system for the treatment of organic containing waster water is provided, comprising an anaerobic bioreactor, an aerobic bioreactor disposed rearwardly of the anaerobic bioreactor, and a membrane separation reactor disposed rearwardly of the aerobic bioreactor.

一种含有机污染物之废水处理系统，包含一厌氧反应槽，一好氧反应槽，及一薄膜分离槽；其中前述好氧反应槽系设置於厌氧反应槽之后，前述薄膜分离槽系设置於前述好氧反应槽之后，该系统系利用生物处理法去除废水中的有机污染物，并以薄膜分离固液两相。

Long time, because the main city of Chengdu is located in the hinterland of Sichuan Basin, the seasonal high frequency of calm winds, temperature inversion strength, subject to a special geographical environment and climatic conditions, in a natural state, city over to respirable particulate matter, sulfur dioxide, represented by the proliferation of difficulties in dilution of air pollutants, resulting in a large number of pollutants in the basin, retention, accumulation.

长的时间，因为成都的主要城市是位于四川盆地，平静的季节风高频率的腹地，逆温强度，受特殊的地理环境和气候条件在自然状态，城市对可吸入颗粒物，二氧化硫，由空气污染物的稀释扩散代表的困难，在污染物在盆地，保存，造成大量积累。

Scirpus validus has the big...

这表明湿地植物的选择不仅要考查其对污染物的吸收速率，更要关注其对污染物的吸收容量，并且湿地植物的吸收作用对类二级出水中氮、磷的去除具有更加重要的意义。
