Method for carbonizing concrete turbidity washing liquid and preparing fresh concrete
The invention relates to the field of turbid washing liquid treatment and resource utilization, and particularly discloses a method for carbonizing concrete turbid washing liquid and preparing fresh concrete, which comprises the following steps: introducing carbon dioxide-containing gas into the concrete turbid washing liquid obtained by washing in a concrete production process for carbonization treatment until the pH value of the solution is 6.5 +/-0.2 to obtain a carbonized solution; and mixing the concrete powder by using the carbonized solution as a mixing raw material to prepare the newly prepared concrete. According to the method, effective absorption treatment of the turbid washing liquid can be realized, and the turbid washing liquid can be used as a raw material for preparing high-requirement concrete, so that high-performance concrete can be prepared in a recycling manner. In addition, the method can be applied to concrete production after carbonization treatment of carbide slag, dry desulfurization products, lithium battery waste residues and the like.
本发明涉及洗浊液处理和资源化利用领域，具体公开了一种混凝土洗浊液碳化并制备新拌混凝土的方法，向混凝土生产工序中冲洗得到的混凝土洗浊液中通入含二氧化碳气体进行碳化处理，直至溶液的pH为6.5±0.2，得碳化溶液；将碳化溶液作为拌合原料用于混凝土粉料的拌合，制得新制混凝土。本发明能够实现洗浊液的有效消纳处理，不仅如此，还能够将其用作原料，用于高要求的混凝土的制备，能够资源化制备高性能的混凝土。并且，本发明可以成为电石渣、干法脱硫产物、锂电池废渣等碳化处理后应用于混凝土生产。
