Method of treating platinum-containing wastewater and recovering platinum carbon

The present invention provides a method of treating platinum-containing wastewater and recovering platinum carbon by using a microbial fuel cell. The method specifically comprises: (1) introducing platinum-containing wastewater into the anode of a microbial fuel cell; (2) collecting an anode biofilm and the remaining sludge; and (3) carrying out carbonization on the anode biofilm and the remainingsludge under the protection of an inert and reducing mixed gas to obtain platinum carbon. Compared to the method in the prior art, the method of the present invention has the following characteristics that the platinum in the platinum-containing wastewater can be recovered and are prepared into the platinum carbon without the generation of secondary pollution, the process is simple, the cost is low, and the application prospect is good. 本发明提供种利用微生物燃料电池处理含铂废水并且回收铂炭的方法。该方法的具体包括以下步骤：（1）在微生物燃料电池阳极通入含铂废水；（2）收集阳极生物膜和剩余污泥；（3）将阳极生物膜与剩余污泥在惰性及还原性混合气体保护下炭化得到铂炭。与现有技术相比，本发明可以在不造成二次污染的条件下，回收含铂废水中的铂并制作成铂炭，工艺简单，成本低廉，具有良好的应用前景。
