Sewage disposal is an important measure to co-exist harmoniously with the nature and promote a cycling city. Yingkou Circle Water System project, undertaken by CNEEC, is for purpose of meeting the requirement of enterprises and residents for reused water. Yingkou project was listed in the important projects of Yingkou in 2006, considered as one of the ten promises that Yingkou Municipal Government made to its citizens.

The designed treatment dimension is 50,000m3/d, of which 30,000m3/d is the flux of the first phase. In this project, we adopted the treatment procedures of folded plate flocculation, inclined tube sedimentation and express filtration in order to eliminate COD, BOD, SS, NH4-N and TP in the used water. We conquered all the difficulties such as the technique difficulty, short term and heavy task and completed the project in time. After the acceptance, it was put into service successfully. CNEEC was highly appraised by Yingkou Municipal Government and the Owner.
