摘要

摘要: 温度影响物质在环境中的存在形态及其生化反应速率,而高寒地区由于常年低温,常规处理方式是否能有效去除该地区污染物仍有待研究。基于此,选用硼选择性螯合树脂处理某高寒地区硼超标地下水,通过现场中试探讨工艺运行参数及效果,采用FTIR、SEM和BET表征探究树脂除硼机理。结果表明:16 BV/h(BV:树脂床体积,1 BV=22.5 L)的进水流速适用于该工程,此时的出水水质可达到GB 5749—2006《生活饮用水卫生标准》;树脂柱的穿透点为871.11 BV,树脂的交换容量为3.58 mg/g;树脂再生水中硼浓度为342.81 mg/L,可用作硼产品生产原料。树脂除硼后,树脂表面羟基官能团含量和孔容减少,且表面出现明显的褶皱,说明树脂对硼的去除过程包括颗粒内扩散和螯合过程。该试验结果可为高寒地区硼超标水处理提供理论支持和技术参考。

Abstract: Temperature affects the existent forms of substances and the rate of biochemical reaction in environmental mediums. Based on this, boron selective chelating resin was used to treat the groundwater with boron concentration exceeding the standard in an alpine region. The operation parameters and performance of the process were determined by field pilot test. And the mechanism of resin boron removal was explored by FTIR, SEM and BET characterization. The results showed that the inlet velocity of 16 BV/h (bed volume; 1 BV=22.5 L) was suitable for the project, and the effluent water quality met the Hygiene Standard for Drinking Water (GB 5749—2006). The penetration point of resin column was 871.11 BV, and the exchange capacity of resin was 3.58 mg/g; the boron content of wastewater generated during resin regeneration was 342.81 mg/L, which could be used as the raw material for boron production. After the boron removal test, the hydroxyl functional group content and pore volume on the surface of the resin were reduced, and obvious wrinkles appeared on the surface, indicating that boron was removed by intra-particle diffusion and chelation process. The results of this experiment can provide theoretical support and technical reference for the treatment of boron in alpine region.
