摘要
针对川北某县级医院扩建的污水处理工程设计,根据污水处理目标及水质水量特点,采用了行业标准未推荐的二级生化处理中的“生物接触氧化+过一硫酸氢钾消毒”工艺进行了污水处理,不仅达到了处理目标,还克服了一级强化处理化学污泥难以处置的困难,也避免了氯消毒等传统消毒方案的弊端,为医疗污水处理提供了一条新思路。该工艺设计可为同等规模的医院污水处理站提供参考,具有一定的实际应用意义。
Aiming at the sewage treatment project design of a county-level hospital in northern Sichuan,according to the sewage treatment target and the characteristics of water quality and quantity,the“biological contact oxidation+potassium persulfate disinfection”process in the secondary biochemical treatment that was not recommended by the industry standard is adopted.The treatment goal was reached;the difficulty of the first-level intensive treatment of chemical sludge was overcome,and the disadvantages of traditional disinfection schemes such as chlorine disinfection were also avoided,which provides a new idea for medical sewage treatment.The process design can provide reference for hospital sewage treatment stations of the same scale,and has certain practical application significance.
