The Shandong Changyi Petrochemical Co has taken steps to improve its wastewater treatment to reach its goal of zero untreated wastewater discharges and to help it save more than 300 tons of fresh water every day. Changyi Petrochemical says that social responsibility is a priority so it does its best to treat wastewater. In January, it did a thorough inspection of its wastewater discharges and used 10 ways to treat wastewater. These helped in the harmonious development of water resource consumption and environmental protection, for example, by treating wastewater containing oil, and that with salt, separately. This year, the company put stricter controls on the discharge of wastewater from facilities, upstream and downstream units were told to report any abnormal water quality or volume from upstream. So, it has developed a comprehensive treatment system of wastewater, upstream and downstream, and at the same time, has adopted a responsibility system for environmental protection, and linked its environmental goals with remuneration for employees and officials. The company has established quotas for water use and is shifting from a water-consumer to a water-conserver.
