Effect of laboratory chemical effluents on the charictristics of hospitals effluents.

This paper focuses on the effect of laboratory chemical effluents on the charictristics of hospital effluents for three hospital (Ibn seena, Ibn alatheer, Alkhansaa). From the comparisin of the effluent discharge with total effluents. The laboratory discharge assumulated about (7-20)% of total discharge effluent of the hospitals.Three locations have been chosen in each hospital,in order to study the characteristic of effluent the pH value is different. Besides the ratio of in the laboratory effluent is higher than other places because of the discharge of chemicals and detergents that used in the laboratory which rise the value of COD in the total hospital effluents and effect on the biological treatment plant.The phenol concentration was about (0.65-2.7)mg/l. The study reach to follow the regular method of casting and handling laboratory chemicals.
