Abstract:
Objective To understand the contents of residual chlorine in the wastewater of 12 hospitals in the urban districts of Jinan. Methods Wastewater samples discharged from 12 hospitals were collected from June to September in 2003. The contents of residual chlorine in the wastewater samples were determined using iodometric titration method and the fecal coliform counts of the wastewater were determined. Results The contents of residual chlorine in the wastewater of 12 hospitals were 3.7 mg/L-128 mg/L with the average level of 27.6 mg/L. The result of the fecal coliform count in the wastewater was accorded with the National Hygienic Standard. Conclusion The contents of residual chlorine in the wastewater discharged from municipal hospitals in Jinan were too high, which might cause the secondary pollution to water environment.
