Abstract

Abstract:

The biological contact oxidation process is used to treat the general medical wastewater and infectious department medical wastewater from a second-grade class-A hospital in Suzhou City. The treatment scale is 600 m³/d, and the effluent quality met effluent the requirements of Discharge Standard of Water Pollutants for Medical Organization(GB 18466-2005). The design and operation of the project are introduced which operation effect is stable. The cost of water treatment per ton during operation is 1.26 yuan.

Key words: hospital wastewater, biological contact oxidation, wastewater disinfection
