改性竹炭对含铅废水吸附处理的效果研究

研究了商用竹炭和改性竹炭对含铅废水的吸附处理的实验条件及效果。结果表明,对一定质量浓度及一定量含铅废水处理时,只要条件和吸附剂竹炭的投放量合适,铅的去除率均可达99.9%以上。以我国饮用水卫生标准中铅含量≤0.05mg/L为标准,根据废水中铅的含量,给出了吸附处理所需吸附剂投料量的估算方法和实验验证结果,为竹炭在含铅废水处理中的应用提供理论依据。

The Effects of Modified Bamboo Carbon on Adsorption Treatment of Lead-Containing Wastewater

This experimental conditions and effects of bamboo carbon for commercial use and modified bamboo carbon on adsorption treatment for lead-containing wastewater were studied.The results show that if the conditions and the quantity of adsorbent are appropriate to certain concentration and certain amount of lead- containing wastewater, the removal ratio of lead can be reached 99.9% and above. According to our country's drinking water standard, 0.05 mg/L Pb is the maximum limit of lead allowed to be contained in water. The estimate method to the quantity of adsorbent needed as well as validate the results by experiments during the treatment of a certain amount and a certain concentration of lead-containing wastewater were researched.It provides a theoretical basis for the usage of bamboo carbon on adsorption treatment of lead-containing wastewater.
