文档介绍：摘要
对1000张病床医院废水采用生物水解酸化+SBR工艺进行处理,通过废水的厌氧与氧化反应,利用水中微生物的新陈代谢作用,降解水中的有机污染物,达到净化水质、消除污染的目的。
本污水处理工程主要采用“化粪池+水解酸化池+SBR池+接触消毒池”的处理工艺。医院废水进入化粪池处理单元沉淀下来,调节池出水进入厌氧单元,通过厌氧生物的降解作用,使有机污染物得到部分降解,便于后期SBR池处理,水解酸化池的出水进入SBR池,有机污染物得到的彻底的降解。经处理的医院废水进入消毒区,在消毒区内利用液氯的强氧化性能有效杀死废水中的细菌和病毒,并具有持续消毒作用。
经消毒灭菌后的出水即可达到《医院染物排放标准》(DB37/596-2006)中的一级排放标准,最终达标排放。同时一部分水作为回用水处理。另外废水处理中的污泥必须得到消毒才能外运。

ABSTRACT
Uses the biology Hydrolytic acidification + SBR craft to the hospital waste water of 1000 beds to carry on processing, through the waste water Anaerobic and oxidation response, in the use water anism's metabolism function, degrades in the water anic pollutant, achieves the purification water quality, the elimination pollution goal.
This sewage treatment project main use “septic tank + Hydrolytic acidification pond + SBR tank + Contact disinfection tank” processing craft. The Hospital wastewater enters the septic tank processing unit precipitation to get down, The regulating reservoir water leakage enters the anaerobic unit, through the anaerobic biological degeneration function, enable anic pollutant to obtain the partial degeneration,which is convenient with processing in SBR tank later, the water of Hydrolytic acidification pool enters the SBR tank, through the biological degeneration function, enable anic pollutant to obtain the thorough hospital treated wastewater enters the disinfection area, achieves the sterilization goal in the disinfection area using the Chlorine strong oxidability.
After the disinfection antiseptic after water leakage then achieved "Hospital Dyes Emissions Standard" (DB37/596-2006) level emissions standard, finally attains a designated standard the the part of the water is treated as the back water. In addition, wastewater treatment sludge must be disinfected before sinotrans.
