摘要
众所周知,Cr3+是一种污染性很强的重金属.前人已经测定趋磁细茵对Cr3+的吸附可以达 到0.1×10-6的水平,因此本文不考虑排放标准的问题,主要研究pH值、温度、时间以及微生物 量等因素对趋磁细菌吸附cr3+的影响,并考虑其符合的吸附模型.
As is well known, chromium(Ⅲ) is a strongly contaminated heavy metal ion. The formers have concluded that it can reach the level of 0. Ippm when the wastewater including chromium (Ⅲ) is treated by magneto-tactic bacteria(MTB) therefore the problem about the standard of outlet water is not dealt with here. A chief study is carried on the influence on the MTB's absorption of chromium(Ⅲ) by factors such as pH, temperature, time and the quantity of the MTB. At the same time, the absorption models it suits are also analyzed.
