Expansion of organic chemicals contamination especially which have endocrine disrupting effects in wastewater threat environment health by contaminate water resources and food chain by deposit in sea products. Considering the disadvantages of these chemicals on environment and human health, it is essential to treatment and elimination of these pollutants, however, in most countries there is no official rules for destruction of endocrine disrupting chemicals. We were chosen Estrone and 17 β Estradiol to study, regards watch list in the field of water policy of European Union (DIRECTIVE 2013/39/EU). Real samples were gathered from effluent of a wastewater treatment plant (WWTP) with input of both municipal and industrial wastewater. Row sewage was exposed to physical, chemical and biological processes in the WWTP. Solid phase micro extraction method by hollow fiber has used for samples extracting due to its compliance with green chemistry. Hollow fibers provide fast and sensitive extraction method for volatile organic compounds. Under optimum extraction condition, HPLC used for measures Estrone and 17 β Estradiol. After assessing the contents of studied analytes, the pilot reactor was designed to complete the treating system. In added system, treated wastewater was passed over glass surface covered by titanium dioxide (TiO2) under UV light. Using photocatalytic process has shown a great potential for wastewater treatment technology. Optimum refining condition was selected through changes in effective factors in degradation. Experimental results shown the efficient effects of photocatalytic system on studded chemical materials. TiO2 photocatalytic modifications can successfully utilized for the degradation of organic pollutants in wastewater treatment plants.
