The invention discloses a method for preparing high-quality titanium white from titanium-containing solution. The method comprises the following steps of: adding kali salt, zinc salt and aluminum salt into the titanium-containing solution to atomize the titanium-containing solution; adding the atomized titanium-containing solution into a reactor dropwise; introducing hot air into the reactor and hydrolyzing the titanium-containing solution at the temperature of between 150 and 350 DEG C so as to generate solid-phase hydrated titanium dioxide; and calcining the hydrated titanium dioxide at thetemperature of between 300 and 1,000 DEG C for 1 to 5 hours so as to obtain the high-quality titanium white. In the method, continuous spray hydrolysis is used instead of the conventional intermittent liquid-phase hydrolysis, so that reaction speed is high, yield is high, problems encountered in the conventional titanium white producing process by a sulfuric acid method can be solved effectively,product quality is enhanced, damage to the environment is avoided and the production cost of the titanium white can be lowered simultaneously.
