Question

哪位高手能帮我翻译一下（英译汉）

The low mobility observed for chromium and copper ions (threshold pH of 2–3) suggests that the adsorption strength of these metals to the various fractions present in the sludge is not easily overcome by the acid and oxidative environment of the bioleaching process. On the other hand, in previous works (Green et al. 1998), nickel ions showed a low affinity to organicmatter in sludge,
whereas low stability constants were reported for zinc humic acid complexes (Takahashi et al. 1997). Such previous observations could explain the readily solubilization (threshold pH of 6–
6.5) observed for nickel and zinc ions in the present study.
As a conclusion, from the present study, it was possible to obtain a consistent correlation between the sludge pH and the solubilization of chromium,copper, nickel and zinc ions during bioleaching of anaerobically-treated sludge. Some possible explanations were also raised for the solubilization profilesobtained based on fractionation analysis. Finally, the establishment of solubilization patterns independent of the sludge solids concentration can be of great usefulness when predicting the efficiency of bioleaching systems based on pH measurements.

Answer 1

低流动性观察铬和铜离子（阈值pH值2-3 ）表明，吸附强度的这些金属的各种组分在污泥是不容易克服的酸和氧化环境中的生物过程。另一方面，在以前的作品（绿等人。 1998年） ，镍离子显示低亲和力organicmatter的污泥，而低稳定常数报告锌腐植酸复合物（高桥等人。 1997年） 。例如以前的意见可以解释容易溶（阈值pH值6 - 6.5 ）观察到的镍和锌离子在本研究中。
作为一个结论，从目前的研究，有可能取得一致的相关性污泥pH值和溶的铬，铜，镍和锌离子在浸出厌氧处理的污泥。一些可能的解释，也提出了溶profilesobtained基于分馏分析。最后，建立独立的溶模式污泥固体浓度可以是非常有用的效率时，预测的生物系统的pH值测量。
