紫外線照射による下水処理水中の女性ホルモンの削減に関する基礎的研究

抄録

The female hormone exhausted from the human body has from about 1, 000 to 10, 000 times stronger estrogens activity than a typical chemical to which the endocrine disrupter's action is suggested. Therefore, the research on effective reduction of the female hormone was conducted with an experimental apparatus by the continuous supply method using only ultraviolet rays because combination of ultraviolet rays with other technologies complicates the management of operation in the sewage plant. The treated wastewater was continuously supplied into the experimental apparatus, ultraviolet ray was radiated, and the reduction effect of El and E2 were measured while changing the irradiation time. The result of the experiment reveals the possibility to treat female hormone in the treated wastewater by ultraviolet rays.
