In present paper, photochemical degradation procedure of the methyl thionine chlorise as organic pollutants has been studied. The experiments research affecting factors such as the time and temperature of photocatalytic degradation,the amount of catalyst, the pH value of solution, the initial concentration(c0) of Methylene Blue and the flow of solution circulation(v),etc.The maths model is founded. The result is that when T= 35℃,c(TiO2)=400 mg·L-1,pH = 8, c0= 3 mg·L-1, v= 10 L·h-1, t=90 min,the initial Methylene Blue is reduced up to 94.6%.
