Method for co-processing soil compositely polluted by multiple heavy metals through cement kiln
The invention discloses a method for co-processing multiple heavy metal compound contaminated soil by a cement kiln, which comprises the following steps: step 1, during use, placing limestone and sandstone into a drying box for drying, and after drying, placing the contaminated soil and the dried limestone and sandstone into a crusher for crushing treatment, and after crushing, adding the crushed mixture into a low-speed mixer for stirring and mixing. According to the invention, through the mutual cooperation of an air extracting pump and a filter, during use, generated high-temperature gas can be effectively recovered, so that the utilization rate of the whole method is effectively ensured, the utilization rate of calcined gas after calcination is ensured, and the utilization rate of the calcined gas after calcination is ensured. Meanwhile, through the arrangement of the method, the treatment effect on heavy metal can be effectively improved during use, and the mixing effect of the heavy metal and cement is better.
本发明公开了一种水泥窑协同处置多种重金属复合污染土壤的方法，包括以下步骤：步骤一、在进行使用的时候，将石灰石和砂岩放置到烘干箱进行烘干，在进行烘干后，将污染土和烘干后的石灰石与砂岩一起放置到破碎机中进行破碎处理，在进行破碎后，将破碎后的混合物加入到低速混合器中进行搅拌混合。本发明通过设置的抽气泵和过滤器之间的相互配合，使得在进行使用的时候，可以有效的起到对产生的高温气体进行回收的，进而有效的保证了整个方法的利用率，进而保证了在进行煅烧后，对煅烧后的气体的利用率，同时通过上述方法的设置，使得在进行使用的时候，可以有效的提高了对重金属的处理效果，使得其与水泥之间的混合效果更好。
