10 Mg/L respectively. Heavy metals were recovered with H2SO4 or HNO3 to dispose heavy metal bearing residues.

含有重金属盐的残渣，可用硫酸或硝酸处理，以回收重金属。

As a result, heavy metals are transported directional under the DC electric field. The feasibility of electrokinetic technique in remediation of heavy metal contaminated soil has been demonstrated in this thesis.

论文考察了动电修复技术去除土壤中重金属污染物的可行性并针对该技术中存在的问题提出了阳离子选择透过膜强化的动电修复技术。

Concentrations of heavy metals in the suspended matter and sediment are not obviously affected by elutriation of stream and dilution of tributary stream. This feacture does not change even in the distant reach downstream. Therefore, the suspended matter and sediment are the potential source of heavy metal contamination to the waters for industry and agriculture use.

河流的地质、水文特征决定了河流悬浮物和沉积物成为河流中重金属搬运迁移的主要载体，在几十公里的下游水域中悬浮物和沉积物中重金属含量没有受到其它支流清澈水体的稀释，成为下游工、农业用水的潜在污染源。

The results show that coal mining spoils contributed heavy metal pollution of the coal mining soil and heavy metals accumulation is caused by coal mining spoils piled up, catamorphism and eluvium.

由此可见，矿业开采活动对当地土壤重金属含量有一定的贡献，但不同的重金属元素在矿区土壤中的积累表现出差异性。

Extreme metal is an umbrella term, somewhat loosely defined, for a variety of heavy metal subgenres developed since the 1980s.

"极端金属"於20世纪80年代从"重金属"中发展出来。

Effects of time, water flux density, and distribution coefficients of metal ions on the migration and concentration distribution of heavy metal ions were also simulated in soil.

分析了时间、水的通量密度、金属离子的吸附分配系数对金属离子在土壤中迁移及浓度分布的影响。

The results indicate that the migration of heavy metal ions in soil is mainly dominated by the water flux density and distribution coefficients of the metal ions sorption to soil.

结果表明，金属离子在土壤中的迁移主要受水的通量密度和吸附分配系数的影响，并随时间的增加而增加。

The most polluted areas is near Tianjin second gasworks and around sewage river as well as sewage irrigation area. So we can conclude the major sources of pollution is atmospheric deposition and sewage irrigation. Second, It is positive correlation between the heavy-metal contamination and layered silicate minerals, while it is negative correlation between heavy-metals and quartz , feldspar as well as other minerals.

二、重金属污染元素含量与层状硅酸盐矿物含量呈正相关，而与石英长石等矿物含量呈负相关，充分说明污染元素主要赋存在层状硅酸盐矿物中，这与矿物自身的结构有着密切的关系，层状硅酸盐矿物具有很大的层间域，有利于对其他物质的吸附作用。
