水解酸化-生物接触氧化工艺处理医院废水的效果

目的 研究水解酸化-接触氧化工艺处理医院废水的工程应用，为医院废水处理提供一种科学的方法。方法 处理工程采用水解酸化 二氧化氯消毒组合工艺，处理流程分为兼性段和好氧段。结果 经过半年多的实际运行表明，该工艺在进水生化需氧量(BOD5)150mg／L、化学需氧量(CODCr)300mg／L、固体悬浮物(SS)300mg／L、pH值6～9、粪大肠菌群50000个/L的条件下，污水经处理后，水质达到GB8978-1996《污水综合排放标准》表4中二级标准。结论 该工艺处理医院废水的工程具有较好的实际应用价值和明显的经济效益。

Hospital Wastewater Treatment With the Hydrolysis Oxidization Technology

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.
