本文在简述含氯废气的产生、来源和危害的基础上，结合我国锌矿资源基础储量大、贫矿多、富矿少、氧化矿占基础储量比例大的特点，选择了贵州省的某含铁氧化锌矿作为原料吸收含氯废气，通过正交实验试验表明本次实验中的最优条件为A2B2C2，即液固比为7:1，粒度为120目，吸收时间为70分钟，锌的利用率为99.87%，可使含氯废气的吸收率达99.88%以上。用含铁氧化锌矿吸收含氯废气吸收率高，效果显著，成本低廉，含氯废气经吸收后完全可以达标排放，同时为氯化锌的生产提供原材料，可获得一定的经济收益，该试验是将资源利用与环境保护相结合的尝试，具有一定的实用价值。为今后的工业化应用奠定了一定的基础。

Experimental Analysis on the absorption of Chlorine Exhaust Gas by Ferruginous Zinc Oxide Mine
Abstract
This paper in intended to analysis the origin and harm of chlorine exhaust gas, along with the characteristics of large fundamental reserves of Zinc mine, more lean ore, more rich ore, with the oxidized mine taking up a great proportion of reserves in our country. Taking certain ferruginous zinc oxide mine as the experimental materials to test its absorbability of chlorine exhaust gas, as is shown by the orthogonal experiment, the optimal condition for the experiment is A2B2C2. That is to say, the liquid-solid ratio is 7:1, granularity 120 with the absorbing time of 70 minutes and zinc utilization up to 99.88%. Ferruginous zinc oxide mine not only has a high absorption rate of chlorine exhaust gas, but it also works wonders at a low cost. Chlorine exhaust gas can be emitted after absorption safely within the standard. Meanwhile, it can also used as the materials to produce Zinc chloride, thus bringing into some extra economic benefits. This experiment is a trial based on the combination of the utilization of resources and environmental protection. And its Practical value will prove to set a good foundation for its further Industrial application
