一种处理黄磷尾气的方法
摘要：
本发明涉及一种处理黄磷尾气的方法，包括使黄磷尾气与铬渣进行接触以使黄磷尾气中的还原性气体与铬渣中的六价铬进行氧化还原反应。该方法不仅几乎可以一次性除去黄磷尾气中的有毒气体，具备了经简单燃烧处理后即可直接排放的条件，而且还使铬渣中的六价铬被有效地还原，并且还原后的铬渣不容易返黄。该方法能同时解除黄磷尾气和铬渣的毒性，达到以废治废、变废为宝的目的，是一种不会造成二次污染的环保型新工艺。
摘要（英）：

The invention relates to a method for treating a yellow phosphorus tail gas. According to the method, the yellow phosphorus tail gas to come into contact with chromium slag so that reducing gas in the yellow phosphorus tail gas and hexavalent chromium in the chromium slag have a redox reaction. The method can be used for removing harmful gases out of the yellow phosphorus tail gas at one time, the yellow phosphorus tail gas can be directly exhausted after being combusted simply, the method also can be used for effectively reducing the hexavalent chromium in the chromium slag, and the reduced chromium slag is unlikely to become yellow. The method can be used for simultaneously removing the toxicity of the yellow phosphorus tail gas and the chromium slag, thereby reaching the purpose of treating waste with waste and turning waste into wealth. Therefore, the method is an environmental-friendly novel process generating no secondary pollution.
