红色链霉菌丝体处理含Pb^(2+)废水的试验研究

Study on Experiment of Red Streptomyces Applied in Treatment of Pb^(2+)-containing Wastewater

该文采用非活性红色链霉菌对含Pb^(2+)废水进行研究,找出了溶液pH值、废菌体用量、共存离子、吸附时间等影响Pb^(2+)吸附的显著因素。对实际含Pb^(2+)废水处理结果表明,经过二级吸附处理后的实际废水能达标排放。

In this paper, the non-active red streptomyces was utilized to adsorb Pb^2＋ from Pb^2＋-containing wastewater in the laboratory and some factors which effect lead uptake greatly such as pH value,dosage of red Streptomyces,co-existing ions ,contacting time were found. The results showed that after two stages treatment, the concentrations of heavy metals in the effluent all meet the standards for wastewater discharge.
