    清河污水處理廠總服務人口約81.4萬，廠區總占地面積30.1公頃�？偺幚硪幠�為40萬m3/d。一期工程處理能力20萬m3/d，總投資4.42億元人民幣，其中使用瑞典政府貸款折合人民幣8300萬元，2002年9月建成通水。二期工程處理能力20萬m3/d，總投資2.75億元，2004年12月建成通水。
    清河污水處理廠一期采用倒置A2/O工藝，二期采用A2/O工藝，均具有脫氮除磷功能。為減少占地，設計上無初沉池和濃縮池，增設化學除磷池。處理廠的主要設施包括：進水泵房、曝氣沉砂池、生化反應池、沉淀池、鼓風機房、脫水機房等�！�
清河污水處理廠建成后，還將籌建一座日產8萬立方米再生水深度加工廠，為奧運公園提供補充水源。 

Qinghe Wastewater Treatment Plant Introduction

Qinghe Wastewater Treatment Plant takes up a 30.1-hectare building area and serves a population of 814,000 within the scope of 159.42 square kilometers. Qinghe waste water treatment plant locates on the north bank of Qinghe river-Mafang village which is on the east of Qinghe town. The planned capacity is 400,000m3/d. The first-stage project is capable of treating 200,000m3/d with the total investment of ¥442,000,000 including ¥8,300,000 of loan from Sweden government, completed in sep. 2002. The second-stage project completed in Dec 2004 with the capacity of 200,000 m3/d and total investment of ¥275,000,000.
The inverse A/A/O and A/A/O process are introduced respectively in the different stage, and these two processes have the function of removing phosphorous. To economize the land for building, the first sedimentation tank and the concentration tank are omitted from the process, meanwhile the phosphorous removal station is added. The main facilities of the plant includes: inlet pumping station, aerated grit chamber, biochemical reaction tank, sedimentation tank, air blower room and sludge dewatering room.
A water reclamation plant with the membrane treatment scale of 80,000 m3/d will be bulit in 2006, and reclaimed water will supplement water for Olympic Garden.
