摘　　要：在对已建调蓄池臭气排放特征调研的基础上,针对目前土壤除臭技术存在的问题,提出了改良土壤除臭技术。选取砂土和瓜子片作为土壤改良介质,考察了污染负荷、温度、运行时间间隔等因素对除臭效果的影响。结果表明,在试验条件下,除臭装置对NH3和H2S的去除速率均随污染负荷的增加而增大;除臭系统的运行效果受温度影响较大,温度对NH3和H2S去除速率的影响规律均符合Arrhenius方程;除臭装置可以间歇运行,但对臭气的去除率会有所降低;在冬季低温、低浓度、间歇运行条件下,除臭装置仍可适用。Based on investigation of the odor emission characteristics of the built storage tanks, the improved soil deodorization technology was proposed to solve the problem existing in the current soil deo- dorization technology. Sand and gravel were used as the medium for improving soil. The influence of pol-lution load, temperature and operation time interval on the deodorization effect was investigated. The results showed that under trial conditions, the removal rates of NH3 and H2S by deodorization device were increased with the increase of the pollution load. The operation effect of deodorization system was greatly influenced by the temperature, and the influence law of temperature on the removal rates of NH3 and H2S was consistent with Arrhenius equation. The deodorization device could be intermittently operated, but the removal rate of odor would be reduced. The deodorization device could still be applicable under the conditions of low temperature in winter, low concentration and intermittent operation.
