Design and Running for a Hospital Wastewater Treatment Project

摘要

A combination process of biological contact oxidation, membrane bioreactor (MBR) and sodium hypochlorite disinfectant was utilized to treat hospital wastewater. The amount of wastewater is about 200 m~3/d. As a result, COD and NH_3-N of treated water are less than 50 mg/L and 10 mg/L, respectively. Total coliform and fecal coliform were not detected in the treated water. The main indexes could meet the requirement of Chinese Discharge Standard of Water Pollution for Medical Organization. With reasonable design and low cost of investment and running the hybrid process may be a good guide and reference for similar projects.
