Method for preparing ceramsite by using chromium-containing sludge
The invention discloses a method for preparing ceramsite by using chromium-containing sludge. The method comprises the following steps: carrying out reduction roasting treatment on the chromium-containing sludge, mixing the chromium-containing sludge with pulverized coal and/or saw dust, dehydrated silicon-aluminum tailings, limestone and water, granulating the mixture, and drying and sintering the granules to obtain the ceramsite. According to the method, the problem of pollution to human bodies and the environment in a hexavalent chromium sludge recycling process is solved, meanwhile, the hexavalent chromium sludge is recycled, and huge economic and environmental benefits are achieved.
本发明公开了一种利用含铬污泥制备陶粒的方法。该方法是将含铬污泥进行还原焙烧处理后，与煤粉和/或锯末、脱水硅铝质尾矿、石灰石及水混合造粒，粒料经过干燥和烧结，即得陶粒。该方法在解决六价铬污泥资源化过程中对人体及环境污染的同时实现了其资源化利用，具有巨大的经济与环境效益。
