摘要
针对受硝基苯污染的松花江水,研究了应用粉末活性炭去除硝基苯的技术参数.试验结果表明,针对受污染的松花江水,唐山产木质PAC对硝基苯的吸附速度最快,吸附容量也最大;其具体投加参数为：硝基苯超标5-15倍时投加30 mg/L的PAC,15-40倍时投加50 mg/L的PAC,吸附时间2 h以上;硝基苯超标大于50倍时,PAC的投量80 mg/L,吸附时间不低于2 h.应用PAC的生产性试验结果表明,出水硝基苯含量低于国家标准,并且具有很高的稳定性.
Powdered activated carbon （PAC） is employed to adsorb nitrobenzene from polluted Songhua river and the technical parameters are studied. Results show that the xyloid PAC produced in Tangshan presents the fastest adsorption rate and the maximum adsorption capacity to nitrobenzene. The optimum parameters are presented below： the dosage of PAC is 30 mg/L when the concentration of nitrobenzene exceeds the national standard for 5 - 15 times, and 50 mg/L when the concentration of nitrobenzene exceeds the national standard for 15 40 times, both with an adsorption time of over 2 h; the dosage of PAC is 80 mg/L when the concentration of nitrobenzene exceeds the national standard for more than 50 times with an adsorption time of no shorter than 2 h. The results of full - scale experiment show that the nitrobenzene concentration in the effluent meets the national standard with a highly stable value.
