摘要：

围绕医院污水达标排放这个课题,探讨了目前医院污水处理工艺技术状况,在此基础上,进一步从工艺效果、经济效益和社会效益等方面探讨医院污水处理工艺发展趋势。国内外的一些工程实践证明:周期性循环活性污泥法(CASS)工艺配合二氧化氯消毒工艺能使二级处理的费用达到三级处理的出水效果,是目前医院污水处理最理想的方法。对医院污水中特殊污染物的处理提出了单独处理的建议,并从经济和工艺效果角度提出好的处理方案。

Abstract:

The status quo for the present hospital sewage disposal technology is discussed according to the task of hospital sewage drainage which reaches the standards. The developmental trend for hospital sewage processing technique is further probed from the aspects of technical, economical and social benefits. Some engineering practice shows that CASS technic cooperating with chlorine dioxide disinfection is the best method for the hospital sewage disposal which makes the drainage quality reach Grade 3 standards only with Grade 2 disposing cost. For hospital unusual sewage,separate disposal is necessary and the finer disposing projects should be offered according to economical and technical benefits.

Key words: hospital sewage, technology of sewage disposal, periodical activated sludge system, disinfection
