饮用水源突发性柴油污染的吸附法应急处理模拟试验
Simulated Experiment of Emergency Treatment for Raw Water with Exfoliated Graphite Adsorption Process while the Accidental Diesel Oil Pollution of Drinking Water Source
摘要
Abstract
Simulated experiments were performed in laboratory. Exfoliated graphite adsorption method was used as emergency treatment technology of drinking source water which was suddenly polluted by diesel oil. The effect of shaking time, pH, exfoliated graphite dosage and temperature on the adsorption were investigated. The adsorption isotherms were determined and the thermal adsorption law was also discussed. The results show that exfoliated graphite can diminish unexpected diesel oil pollution quickly and efficiently. Under this research conditions, shaking rate, pH and temperature have no influence on the adsorption. When exfoliated graphite dosage is 5g/L, the removal rate of diesel oil can reach more than 97 ％ during 5 s, with regard to 1 000 mg/L of diesel oil in water. The isothermal adsorption law can be well described by Freundlich model. The acquired linear equation may supply instrumental model to emergency treatment of drinking source water suddenly polluted by diesel oil.关键词
