[Text by Gao Jing from General Department of Xinzheng Kangda]
On the afternoon of August 27, 2019, the staff of four water plants under the jurisdiction of Xinzheng Branch went to visit and study in No.1 Sewage Treatment Plant of Zhengzhou Xinzhongzhou Water Co., Ltd. Li Guanghui and Gao Yantao, deputy directors of Zhengzhou Xinzhongzhou Water Co., Ltd., led all the participating staff to learn relevant processional knowledge.
At the beginning of the study, the staff members were divided into two groups to learn the professional knowledge related to the newly installed generating set. And they followed Director Li to learn technologies of No.1 Sewage Treatment Plant and key points of operations in site. Alongside from that, they learned differences between CASS process and oxidation ditch process, and their respective advantages and disadvantages.
As a brushless synchronous alternating-current generator, the generator newly installed in Zhengzhou Xinzhongzhou Water Co., Ltd. can avoid the production suspension caused by power cut due to unexpected electric supply failure of the city and at the same time, it can save operation cost to the greatest extent. The staff listened and recorded carefully. After getting familiar with each operation step, some staff volunteered to demonstrate "start" and "stop" operations of the generating set under the guidance of the generator factory engineer, laying a solid foundation for the practical application in future work.
