粉末活性炭工艺去除水中1,1,2,2,3-五氯丙烷

摘要

In this study, batch experiments were conducted to investigate the adsorption characteristic of 1,1,2,2,3-pentachloropropane. In pure water and raw water when concentration of 1,1,2,2,3 -pentapropane is 5 times the limit value of national standard, the amount of carbon dosage is 20 mg/L, and powdered activated carbon (PAC) adsorption time are 30 min and 60 min , the concen tration of 1,1,2,2,3-pentachloropropane in water are 0.029 7 and 0.031 0 mg/L, the removal rates are 81.8 % and 79.3 %, respectively. When maximum amount of carbon is 80 mg/L, the highest 1,1,2,2,3-pentachloropropane concentration which PAC can respond to are 0.78 and 0.61 mg/L in pure water and raw water.%该文研究了1,1,2,2,3-五氯丙烷在粉末活性炭上的吸附特性,在纯水和原水中5倍国标浓度条件下,投炭量为20 mg/L,吸附30和60 min,水中1,1,2,2,3-五氯丙烷的浓度为0.029 7和0.0310 mg/L,去除率为81.8％和79.3％.纯水、原水条件下,最大投炭量为80 mg/L条件下可以应对的1,1,2,2,3-五氯丙烷的最高质量浓度分别为0.78和0.61 mg/L.
