Efficiency Evaluation of Hospital Wastewater Treatment System: A Case Study of Ayatollah Nabavi Hospital in Dezful

The amount if pollutant and other hazardous and disease-causing agents in hospitals' wastewater are much higher than the domestic sewage. Thus, this subset of wastewater is really hazardous for both environments and people living in them. The purpose of this study is to investigate the efficiency of wastewater treatment system of Ayatollah Nabavi Hospital in Dezful on the treatment of pollutant agents within wastewaters. In this study, which was administered from November 2015 to April, 2016 (6 months period), the efficiency of wastewater treatment system has been investigated. The parameters under study included turbidity, PH, BOD, COD, TDS, TSS, Fecal Coliform and total coliform, Ammonium and Chloride in the input wastewater entering into the refinery and the output refined wastewater. The whole investigation was made on the basis of "Standards on Measuring Methods" book.
