Assess and compare the quality of hospital sewage Tehran and Rasht the standard

Background and Aim: Today, hospital waste is one of the problems facing human societies. Hospital waste contains toxic and dangerous compounds, infectious substances, biological microorganisms, toxic chemicals effluents (resulting from x-ray film processor and disinfectants) and pharmaceutical compounds. The absence of treatment and improper disposal can be a very dangerous to the environment and human’s health. The purpose of this study was to evaluate the performance of wastewater treatment and disposal condition and the quality of hospitals effluent of Hospital in Giulan and Tehran. Materials and Methods: This cross-sectional descriptive research studied the wastewater treatment and disposal systems condition and effluent quality in heshmat rasht, aria rasht, rasol akram rasht, ۱۲ Bahman Tehran, erfan tehran, alghadir tehran, fayazbaghsh tehran, hospitals. Tested for pH, BOD, COD, TSS and TC in the effluents of wastewater treatment plants using the current standard methods. Results: The Mean values of pH, TSS, BOD, COD, Total coliforms and fecal coliforms in wastewaters- outlet from the studied hospitals were ۱۲ bahman (۲۹۰ total and ۱۵۰ fecal) alghadir (۴۶۰total and ۲۴۰ fecal) erfan (۲۹۸ total and ۱۷۱ fecal) fayazbaghsh (۲۹۰ total and ۱۵۰ fecal) aria ((>۱۱۰۰ total and >۱۱۰۰ fecal) heshmat (>۱۱۰۰total and >۱۱۰۰ fecal) rasol akram (>۱۱۰۰ total and >۱۱۰۰ fecal) respectively. Conclusions: The mean value of TSS, BOD, COD and TC in the wastewater- outlet of the studied hospitals especially the hospitals studied, Gilan province Higher than the standard output of the country has been approved by the environmental protection agency of reducing the effectiveness of sewage purification systems remove dirt by at these centers. Therefore, the basic overview in order to improve the effectiveness of this type of treatment in the areas of design, operation and maintenance.
