云南某造纸厂原有废水处理系统只有一级物理处理设施，且其生产规模正在逐步扩大，原有的废水处理系统已经无法满足要求。本次改扩建采用浅层气浮-水解酸化-A/O-高级氧化-BAF-多相气浮-转盘过滤为主体的处理工艺。运行结果表明：废水CODCr、 BOD5、 SS、 NH3-N、 TP的去除率分别达到98.03%、99.20%、99.00%、75.01%、98.31%，出水水质达到GB 18918-2002《城镇污水处理厂污染物排放标准》一级A标准的要求。介绍了工艺流程设计，给出了主要构筑物设计参数及投资运行成本。
雲南某造紙廠原有廢水處理繫統隻有一級物理處理設施，且其生產規模正在逐步擴大，原有的廢水處理繫統已經無法滿足要求。本次改擴建採用淺層氣浮-水解痠化-A/O-高級氧化-BAF-多相氣浮-轉盤過濾為主體的處理工藝。運行結果錶明：廢水CODCr、 BOD5、 SS、 NH3-N、 TP的去除率分彆達到98.03%、99.20%、99.00%、75.01%、98.31%，齣水水質達到GB 18918-2002《城鎮汙水處理廠汙染物排放標準》一級A標準的要求。介紹瞭工藝流程設計，給齣瞭主要構築物設計參數及投資運行成本。

A paper mill in Yunnan province was only equipped with one-stage physical facilities for wastewater treatment; however, with the expansion of the production scale, the original system can hardly meet the requirement. In view of the above fact, the wastewater treatment project of the said paper mill was reconstructed and expanded with shallow air flotation-hydrolytic acidification-A/O-advanced oxidation-BAF-multiphase air flotation-turnplate filtration as the main process. The operation results showed that, the removal rates of CODCr, BOD5, SS, NH3-N, and TP reached 98.03%, 99.20%, 99.00%, 75.01%and 98.31%respectively, the effluent water quality meet the specification for class A grade 1 in GB 18918-2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant. The design of the process flow was introduced, besides, the design parameters of main constructions as well as the investment and operation cost were offered at the same time.
