竹炭对含汞废水吸附处理的研究

The Effects of Bamboo Charcoal on Adsorption Treatment of Mercury-Containing Wastewater

研究了商用竹炭和改性竹炭对含汞废水的吸附处理条件及效果。以我国饮用水标准中汞的限值0.001 mg.L-1为标准,研究一定浓度及一定量含汞废水处理时,所需吸附剂投料量的估算方法和实验验证结果,为竹炭在含汞废水处理中的应用提供理论依据。结果表明,控制合适的吸附条件,竹炭能有效地去除废水中的汞。

This study examines experimental conditions and effects of bamboo charcoal for commercial use and modified bamboo charcoal on adsorption treatment for mercury-containing wastewater. According to our country＇s drinking water standard, 0. 001 mg·L^-1 Hg is the maximum limit of mercury allowed to be contained in water. The research studies method to estimate the quantity of adsorbent needed as well as validate the resuits by experiments during the treatment of a certain amount and a certain concentration of mercury-containing wastewater. The aim is to provide a theoretical basis for the usage of bamboo charcoal on adsorption treatment of mercury-containing wastewater. The experimental results certify that bamboo charcoal is capable of fully removing mercury containment in wasterwater under appropriate control of adsorption conditions.
