上海某方舱医院污水处理系统分析

Analysis of Wastewater Treatment System of a Mobile Cabin Hospital in Shanghai

文章介绍了上海某方舱医院处理量达500 m^(3)/d的污水处理系统,主要包括污水处理系统的工艺设计流程、工艺原理等内容,并对系统的运行效果进行了分析。来自方舱的混合污水通过专门管道收集后经预处理系统、一体式生化系统及最后的末端消毒系统进行处理。结果显示,经过该系统处理后出水余氯质量浓度稳定在6.5~10.0 mg/L,且上午、下午不同时间段成有规律的相关性,pH值稳定在6~9,余氯值和pH均能够满足规定的污水排放标准。说明该处理系统对于此类污水具有较好的处理效果,为类似项目的污水处理提供了一定的参考。

Wastewater treatment system of a mobile cabin hospital with treatment capacity of 500 m/d was introduced in this paper,mainly included the process flow and principle of the wastewater treatment system,and the operation effect of the system was briefly analyzed.The mixed wastewater was collected and discharged into the pre-treatment system,integrated biochemical system and the disinfection device.The results showed that the residual chlorine value and pH value of the mixed wastewater from the medical area and living area in the storage tank were 6.5~10.0 mg/L and 6~9,respectively,which could meet the specified wastewater discharge standards.This treatment system has a good treatment effect and can provide a certain reference for similar projects.
