提高沉钒废水中V^(5+)、Cr^(6+)处理能力的途径

INCREASING ABILITIES OF HANDLING V^(5+)AND Cr^(6+)CONTAINING IN WASTEWATER AFTER VANADIUM PRECIPITATION

通过对还原沉钒废水中V^(5+)、Cr^(6+)还原剂的选用和还原-调pH后溶液沉降速度和固液分离后固体残渣量的研究,找到了一种使沉钒废水中V^(5+)、Cr^(6+)还原速度快、还原-调pH后溶液沉降速度快且固体渣量少的方法。在不增加沉钒废水处理设备的基础上,可提高沉钒废水的处理能力。

After studying on the reductant select of handling V^5 ＋ and Cr^6 ＋ containing wastewater after vanadium precipitation, precipitation speed of solution after pH value being adjusted and reduced, solid residues after solid and liquid being separated, we find out a method on higher reducing speed of V^5＋ and Cr^6 ＋, higher precipitation speed of solution after pH value being adjusted and reduced and fewer solid residues. We can improve the capability greatly on the handling wastewater after vanadium precipitation without processing equipments being not additional added.
