| Abstract: | Nanometer TiO2 powder has been obtained from TNB by sol-gel method. The size and structure of its powder and properties are analyzed by XRD and TEM. Under normal temperature,the effects of the pH, illuminating time and the dosage of catalyst on ethylene industrial wastewater are investigated. The processing conditions of photoeatalytic techniques are optimized. The reached 94.1% and 84.5% ,respectively. degradation rate of COD and ammonia-nitrogen have |
