毕业设计说明书（论文）中文摘要

本污水处理工程主要采用“水解酸化+IC厌氧反应+SBR+气浮”的处理工艺。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。造纸废水进入初沉池处理单元沉淀下来，水解酸化池的出水进入厌氧池，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，厌氧池出水进入SBR，最后进入气浮池，有机污染物得到的彻底的降解。 经处理后的出水即可达到《制浆造纸工业水污染物排放标准》（GB3544-2008）表3中的排放标准，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经过缩水后即可外运。 关键词 造纸废水：IC厌氧：SBR：气浮 毕业设计说明书（论文）外文摘要

Title The preliminary design of the Wuxi papermaking wastewater treatment engineering Abstract This sewage treatment project main use “Hydrolytic acidification pond + IC anaerobic reaction + SBR tank + Gas float”processing craft. Through the waste water Anaerobic and oxidation response, in the use water microorganism's metabolism function, degrades in the water the organic pollutant, achieves the purification water quality, the elimination pollution goal. The Papermaking wastewater enters the primary settling tank processing unit precipitation to get down, the water of Hydrolytic acidification pool enters the SBR tank, through the anaerobic biological degeneration function, enable the organic pollutant to obtain the partial degeneration, which is convenient with processing in SBR tank later, the water of Anaerobic reaction pool enters the SBR tank, Finally enter air-float pool, the organic pollutants thoroughly degradation. After the treatment after water leakage then achieved \standards for discharge of water pollutants \emissions standards, finally attains a designated standard the emissions. While the part of the water is treated as the back water. In addition, wastewater treatment sludge after shrink after sinotrans. Keywords Papermaking wastewater, IC anaerobic, SBR, floating
