Because the aeration equipment of Xuedian Plant was corroded, most of the aerators in the oxidation ditch were completely blocked, resulting in sedimentation of floating mud in the oxidation ditch and secondary sedimentation tank of the plant area. The on-post staff of Xuedian Plant manually salvaged the floating mud day and night and reported the state of operation to group leadership for support.

At 7:30 p.m. on March 20, 2019, after receiving the aeration equipment allocated by the Group, Gao Yantao, Deputy Director of No.2 Plant of Zhengzhou Xinzhongzhou Water Co., Ltd., and Li Guanghui, Deputy Director of Xinzheng Xinkang Xuedian Sewage Treatment Plant, immediately led the company's maintenance and operation teams to start the overnight installation work of the aeration equipment in Xuedian Plant until 3:00 a.m. in the next day.

This overnight installation work of the jet aerators reflects the socialist professionalism and core values of the majority of officials and workers in the Xuedian Plant who are devoted to their duties, take the plant as their homes, love their posts and work hard, serve the people and benefit the society.
