The method in the disclosure is achieved by chemically reacting diluted sulfuric acid generated when industrial sulfate titanium white powder production with a titanium raw material, and controlling an acid/titanium ratio and an iron/titanium ratio so as to produce the nano catalytic wastewater treatment agent. When being used for treatment of dyeing wastewater and other alkaline wastewater, by virtue of alkaline and dilution environment in wastewater, the nano catalytic wastewater treatment agent is subjected to self-fitting hydrolysist to produce a new ecological nano titanium dioxide ultrafine particle as a catalyst for decomposing organic matters in wastewater so as to decompose the organic matters into carbon dioxide and water; a decomposed and oxidized hydrated iron compound is used as a flocculation and adsorption nano particle, achieving the purpose of removing organic matters in wastewater.
