Hospital Wastewater Treatment With the Hydrolysis Oxidization Technology / 环境与健康杂志

ABSTRACT

Objective To study the application of contact oxidization and hydrolysis acidifying technology in hospital wastewater treatment. Methods Hydrolysis combined with chlorine dioxide disinfection was used in the engineering of treatment. Results Even if CODCr was 300 mg/L, BOD5 was 150 mg/L, SS was 300 mg/L, pH was 6-9 and large intestine bacteria number was 50 000/L, the wastewater quality met the requirement of related standard after treated with the present method. Conclusion The present technology was efficient, practical and economical.
