Evaluation of the quality of the sewage and waste selected hospitals of Rasht and Tehran

Introduction and objectives Hospital wastewaters are loaded with pathogenic micro organisms laboratories and pharmaceutical remaining pharmacy part of metabolized radioactive elements and other toxic chemical Products so for wastewater treatment and excretion conditions of have particular importance Aim of this study is Evaluation of the quality of the sewage and waste selected hospitals of Rasht and Tehran nbsp Materials and methods Cross sectional method was performed in In addition to the several part of specialized hospitals were chosen In order to confirmed of hospitals wastewaters composite sampling were conducted from waste and waste points of selection hospitals wastewater plant to assessment from Chemical Oxygen Demand COD Biochemical Oxygen Demand BOD Total Suspended Solid TSS Electrical conductivity EC pH Phosphate PO Fical coliform Fecal coli Total Coliform T Coli and Total Detergents ABS nbsp Results The results showed that examined indicators in waste of total hospitals have decrease after that influent TSS PO pH ABS T Coli and Fecal Coliform at all hospitals were less than standard level BOD and COD value was exceeded the standard restriction alone in waste of Rasol Akram hospital in Rasht Iran While the electrical conductivity were measured higher than standard level in the Aban and Rasol Akram hospitals nbsp Conclusion Studied hospitals is in suitable circumstances if the aeration system action in standard level nbsp nbsp
