The invention provides a treatment method for water containing vanadium, chromium and iron and a smelting process for high chromium vanadium titanium magnetite concentrate. The treatment method for the water containing vanadium, chromium and iron comprises the following steps: filling the water containing vanadium, chromium and iron; controlling temperature of the water containing vanadium, chromium and iron to be higher than a theoretical liquidus temperature of 65-120 DEG C, carrying out bottom blowing, and adding a desilicification agent into a steel ladle in batches; removing slag in the steel ladle or dumping and discharging the slag; blowing oxygen into the water containing vanadium, chromium and iron under the condition that gas is introduced into the steel ladle in a bottom blowing way, wherein oxygen blowing amount is controlled to be 23-32Nm per ton iron, and controlling temperature of the water containing vanadium, chromium and iron in an oxygen blowing process to be higher than the theoretical liq
