污水里含有大量危害人類健康的有害物質,會有寄生蟲大量的繁殖,深切的影響了我們的生活。所以只有經過認真嚴格水質檢測使其達到要求才可以排放。 根據醫院的規模、性質和處理污水排放去向,進行工藝選擇。污水處理所用工藝必須檢測后確保處理出水達標,主要采用的三種工藝有:加強處理效果的一級處理、二級處理和簡易生化處理。工藝選擇原則為:傳染病醫院處理工藝必須采用二級處理,并需進行預消毒處理。處理出水排入自然水體的縣及縣以上醫院必須采用二級處理。處理出水排入城市下水道(下游設有二級污水處理廠)的綜合醫院推薦采用二級處理,對采用一級處理工藝的必須加強處理效果。對于經濟不發達地區的小型綜合醫院,條件不具備時可采用簡易生化處理作為過渡處理措施,之后逐步實現二級處理或加強處理效果的一級處理。
