摘　　要：根据含铊废水的水质特征,开发出了复合纳米吸附深度除铊技术,结果表明:在原水中的铊为0.037 mg/L的条件下,在过流体积比为5000BV时,处理出水仍能稳定达标。吸附能力主要是由于负载的水合二氧化锰粒子的表面羟基的化学吸附作用,在吸附饱和后能够再生使用。该项技术在含铊废水处理工程得到了成功的应用,工程运行结果表明:出水中的铊浓度稳定达到《湖南省工业废水铊污染物排放标准》(DB43968—2014)。According to the quality characteristics of thallium-contained wastewater, an advanced treatment technology of thallium by nano composite adsorption was developed. The results indicated that when the thallium concentration in the raw water was 0.037 mg/L and the flow volume was 5000 BV, the effluent after treatment still complied with the standards. Adsorption capacity mainly came from the hydroxyl chemical adsorption of hydrated manganese dioxide particles and the adsorbent could be regenerated for use after saturation adsorption. The technology was successfully applied in the thallium-contained wastewater treatment engineering projects. Results from the engineering operation showed that thallium concentration of the effluent complied with the discharge standard of thallium for water pollutants in Hunan Province （DB43968-2014） in a stable mode.
