Based on foregoing results, sampled with nonferrous tailings, the expectation of electroremediation technique to dispose tailings are conducted using electrokinetic’s, middle recycle washing technology, bioleaching-electroremediation technology, respectively.

本研究在前面的基础上,以铅锌选矿尾砂为样品,分别用电修复技术、阴极酸化技术和生物淋滤-电修复联合基础处理样品,探索电修复技术在处理污泥中重金属的应用前景。

Bioleaching is cost-effective and promising solution for reducing the content of heavy metals in sludge.

生物沥滤是—种富有前景、经济高效的降低污泥中重金属含量的途径。

Based on the solidification effect, the cement admixing amount of 0.2kg/kg is more appropriate for practical application. Based on the results mentioned above, we can conclude that bioleaching is an effcetive technology in removing heaby metals from contaminated sediments.

基于以上结果,可以看出生物沥浸技术可有效去除污染底泥中重金属,具有较好的应用前景。

With the development of technology and because of the long leaching period and low leaching rate,the traditional bioleaching process needs to be reformed.

传统的生物浸出工艺由于浸出周期长,浸出率低等因素,已经越来越不能满足冶金工业发展的需要。

Acidithiobacillus ferrooxidans(abbreviation:A. f) is one of the bacteria that are applied in bioleaching industry. It can oxidize ferrous、sulfure and partially oxidized sulfur compounds.

嗜酸氧化亚铁硫杆菌(Acidithiobacillus ferrooxidans,简称A.f)是生物浸矿应用最广泛的菌种之一,它能氧化亚铁、硫和还原态的硫化物。

Acidithiobacillus ferrooxidans, as an important microorganism in bioleaching industry, is also one of the most studied organisms in the bioleaching microbial community.

嗜酸氧化亚铁硫杆菌(Acidithiobacillus ferrooxidans)是生物冶金工业中十分重要的一种细菌,也是目前生物冶金的微生物菌群中研究得最多的细菌之一。
