Background and Objective: Hospital wastewater due to having pollutants like pharmaceuticals and antibiotics, chemical and heavy metals and … In the absence of proper treatment and its entry into the receiving waters are causing health risks. This study evaluate treatment and the quality of effluents from a single wastewater hospital Behshahr's Shohada gynecology and compare effluent with environmental standards.
Materials and Methods: The study on wastewater treatment plant was to Descriptive - analytical method 2015-2016 in the hospital A single gynecologic Behshahr's Shohada. In order to determine the sewage quality and efficiency Wastewater treatment plant outlet effluent sampling was performed. Samples of BOD, COD, TDS, TSS, DO, turbidity, free chlorine, fecal coliform and total coliform were analyzed using standard methods.
Results: The average daily water consumption of 33 m3 and the average hospital wastewater generated per bed is 26.4 m3/day. Average parameters BOD, COD, TDS, TSS, DO, turbidity, free chlorine, fecal coliform and total coliform in the outlet effluent treatment plant respectively is 112/25 mg /l, 157 mg / L, 1122/25 mg / L, 138/75 mg / L, 59/5 mg / L, 13 NTU, 1mg / L,4/75 MPN / 100mL, 46 MPN / 100mL.
Conclusion: The results showed that all parameters are above the standard level suitable effluent disposal to receiving the waters were, therefore efficiency is unsuitable the process of and requires management and leadership is more accurate. This wastewater treatment plant also can be used for agricultural use, Discharge into surface waters and catchy wells are not and Total coliform and fecal coliform amounts were measured only by the standards of the Iran Environmental Protection Agency were compatible.
