Considering that Dongying Power Supply Company is scheduled to perform the interruption maintenance to the high voltage line outside Kangda (Dongying) Environmental Protection Water Co., Ltd. on July 30, leaders of Dongying Plant immediately notified all departments to prepare for the power outage, and arranged the Operation Department to complete the emergency maintenance to the settling pond and biochemical pool during this period, in order to make full use of the interruption duration.

For guaranteeing the thorough, effective and quality maintenance, the Machine Maintenance Team and Operation Team cooperated with each other regardless of the burning sun; and leaders of Dongying Plant guided the whole process on the site to rigidly control the quality and safety, as well as coordinate and solve problems at any time. Despite that it was quite toilsome and sweatful working under the scorching sun, staff members performed the emergency maintenance from 06:00 A.M. to 20:00 P.M. without a break, thus, successfully completing the equipment maintenance, ensuring the normal production, and girding the standard effluent discharge.
