医疗废物高温蒸汽处理工艺的二次污染控制——以孝感市医疗废物处置中心为例

Secondary Pollution Control of Medical Waste Treatment by Steam Autoclave Process——A Case of Xiaogan Medical Waste Disposal Center

以孝感市医疗废物处置中心为例,介绍了高温蒸汽处理过程的二次污染控制工艺。结果表明:采用生物脱臭处理工艺,废气中的恶臭污染物可以达到《恶臭污染排放控制标准》(GB 14554—1993)相应排放速率限值要求;采用生化和物化相结合的废水处理工艺,出水水质可以满足《污水综合排放标准》(GB 8978—1996)的二级排放标准要求。

In this paper, Xiaogan Medical Waste Disposal Center was taken as an example for introduction of a secondary pollution control of medical waste treatment by steam autoclave process. The results showed that by application of biological deodorization process, emission rate of odour gas could meet the corresponding limits required in the Emission Standards for Odor Pollutants（GB 14554-1993）. By utilization of combined biochemical and physicochemical treatment process, quality of the effluent complied with level 2 limits required in the Integrated Wastewater Discharge Standard（GB 8978-1996）.
