医院污水处理的关键是采用既经济又有效的方法来杀灭各种有害的微生物,以达到医院污水排放标准(GBJ48—83);乃连续三次各取样500ml进行检验,不得检出肠道致病菌和结核杆菌。大肠菌群总数不得大于500个/L,并保证规定的余氯量。医院污水的消毒方法很多,基本上可分两大类: 1.物理方法:紫外线照射、加热、高压蒸气、冷冻、超声波及X射线等等。 2.化学方法:氯化、臭氧、活性银、石灰、碘酒等等。由于我国当前的技术经济条件,特别是电力供应、设备、投资等因素,目前在国内
The key to hospital sewage treatment is to use an economical and effective method to kill all kinds of harmful microorganisms in order to meet the hospital sewage discharge standard (GBJ48-83); it is a three-time sampling of 500ml for testing, and no intestinal disease can be detected. Bacteria and Mycobacterium tuberculosis. The total number of coliform bacteria should not exceed 500/L and the specified amount of residual chlorine should be guaranteed. There are many ways to sterilize hospital sewage, which can be divided into two major categories: 1. Physical methods: ultraviolet radiation, heating, high-pressure steam, freezing, ultrasonic waves, and X-rays. 2. Chemical methods: chlorination, ozone, active silver, lime, iodine, and so on. Due to China’s current technical and economic conditions, especially power supply, equipment, investment and other factors, currently in the country
