Abstract

One of China largest river, Songhua River was polluted due to the explosion at a PetroChina factory in Jilin province in 2005. A full scale test was carried out to investigate the removal of nitrobenzene in the raw water from polluted Songhua River. The removal and control effects of nitrobenzene by using Powered Activated Carbon (PAC) absorption and Granular Activated Carbon (GAC) filtration as emergent treatments were studied. The results showed that PAC dosage could change from 30mg/L to 50mg/L according to the variation of nitrobenzene concentration in raw water. The dosing point of PAC was at the intake of water source and enough adsorption time could be guaranteed by means of the water transportation pipeline with distance of 11.9km. Full scale study results showed that the nitrobenzene concentration in intake of water plant was below 0.005mg/L after 5 hours adsorption by PAC in intake of water source which nitrobenzene concentration was between 0.03~0.35mg/L.With the GAC filtration as following treatment, nitrobenzene concentration was below 0.001mg/L in purified water. The combined emergent treatments could be used as a good method for Songhua River pollution

活性炭应急治理松花江硝基苯污染的研究

松花江是中国最大的河流之一，由于2005年中国石油在吉林省的一家工厂发生爆炸而受到污染。对松花江原水中硝基苯的去除进行了试验研究。研究了粉状活性炭(PAC)吸附和颗粒活性炭(GAC)过滤作为应急处理对硝基苯的去除和控制效果。结果表明，PAC用量可根据原水中硝基苯浓度的变化在30mg/L ~ 50mg/L之间变化。PAC的加药点在水源取水口，通过11.9km的输水管道可以保证足够的吸附时间。全尺寸研究结果表明，水厂取水口硝基苯浓度在0.03~0.35mg/L之间，水源取水口PAC吸附5小时后，取水口硝基苯浓度低于0.005mg/L。经GAC过滤后，纯化水中硝基苯浓度低于0.001mg/L。联合应急治理是治理松花江污染的一种较好的方法
