【摘要】 为了研究吸附剂对于沼液中重金属的去除能力,实验首先比较D401树脂对模拟沼液和实际沼液中Cu²⁺,Zn²⁺,Pb²⁺,Cd²⁺4种重金属的吸附效果。结果表明,D401树脂对模拟沼液中4种重金属的吸附能力远远高于实际沼液。其次,选取D401树脂、LSC-500树脂及沸石3种吸附剂,比较3种吸附剂对实际沼液中Cu²⁺,Zn²⁺,Pb²⁺,Cd²⁺4种重金属的吸附效果。结果表明沸石对实际沼液重金属的去除效果最差,LSC-500树脂的吸附能力略优于D401树脂。以期该实验结果为今后更高效地处理沼液中的重金属提供基础理论依据。更多还原

【Abstract】 In order to study the ability of adsorbent to remove heavy metals from biogas slurry, the experiment firstly compared the adsorption effect of D401 resin on Cu²⁺, Zn²⁺, Pb²⁺ and Cd²⁺ in simulated biogas slurry and actual biogas slurry. The results showed that the adsorption capacity of D401 resin to the 4 different heavy metals in simulated biogas slurry was much higher than that in the actual biogas slurry. Secondly, three adsorbents including D401 resin, lsc-500 resin and zeolite, were selected to compare their adsorption effects on Cu²⁺, Zn²⁺, Pb²⁺ and Cd²⁺ in actual biogas slurry. The results showed that zeolite had the worst effect on the removal of heavy metals from biogas slurry, and the lsc-500 resin was slightly better than that of D401 resin.更多还原
