摘要:醫院污水的處理近年來越來越受到重視。醫院污水包括醫療污水和生活污水兩部分，主要來自醫院門診部和住院部的化驗室、手術室、藥劑室、洗衣房、浴室等部門。由于醫院污水中含有較多的病原菌，因此，對該種廢水的治理必須引起足夠的重視。否則會造成病原菌的擴散和傳播，危害人的身體健康，污染環境。

　　　根據設計任務，本設計選用生物接觸氧化工藝做為醫院污水的處理工藝，具有投資少，運行費用低，自動化程度高，噪音小的特點，并且處理水質能達到國家規定的排放標準。本設計說明書重點說明了生物接觸氧化工藝在處理小區生活污水時所采用的運行參數、設計的計算方法和過程，以及一些常用水處理構筑物的設計計算方法，通過設計能達到預期的處理效果。

Abstract:Hospital sewage treatment in recent years more and more attention. Hospital sewage including medical waste water and sewage in two parts, mainly from the outpatient department and inpatient hospital laboratory, operating room, pharmacy room, laundry room, bathroom and other departments. Since the hospital contains more pathogens in sewage, so this kind of wastewater treatment must be taken seriously enough. Otherwise it will result in the proliferation of pathogenic bacteria and spread, harm people's health, pollute the environment. According to the design task, the design uses biological contact oxidation process as the hospital sewage treatment process, low investment, low operation cost, high degree of automation, low noise characteristics, and address water to meet the national emission standards. This design guide highlights the biological oxidation process in sewage treatment area when the operating parameters used in the design of the calculation methods and processes, and structures of some common design and calculation of water treatment method, designed to achieve the desired treatment effect.

醫院污水來源及成分復雜，不同部門科室排出的污水成分和水量也各不相同，除含有大量的細菌、病毒、蟲卵等致病病原體外，還含有化學藥劑、重金屬、消毒劑、有機溶劑、酸、堿和放射性同位素等。這些污水具有空間污染、急性傳染和潛伏性傳染的特征，危害性很大。如果未經有效處理排放進入城市下水道或自然水體，往往會造成水體、土壤的污染，引發各種疾病或導致介水傳染病的暴發流行，嚴重危害人們的身體健康。
