The invention relates to a method for utilizing a chrome-vanadium solution to produce a vanadium product and chromium sulfate basic. Through the steps of hydrolysis vanadium depositing, a calcification reaction, enriching of chrome, preparing of chromium sulfate basic and the like, a high-purity vanadium product and a chromium sulfate basic product are obtained, the concentration of the obtain vanadium product can reach 99.5% or above, the content of Cr2O3 in chromium sulfate basic can reach 24-26%, the content of a sundry Fe is smaller than 0.1%, the recovery rate of chrome and vanadium can reach 99.5% or above, and the purposes of efficiently extracting and separating chrome and vanadium are achieved. The production process is clean, saline water and NaOH mother liquor generated in the preparing process can return to a system for use, and no ammonia-nitrogen wastewater is generated in the whole process. The technology is feasible, the equipment is simple, the production cost is low,the automation is easy to implement, the economic benefit is high, and the application prospect is good.
