Construction work has just got under way to upgrade the wastewater treatment plant discharging into the Shi Li river in the north of the country, which forms part of the Beijing catchment. Design was by Australian consultant GHD.
The river has been polluted by toxic wastewater from a coal gasification plant in the industrial city of Datong.
The upgraded plant will be capable of handling 800m 3of water a day, reducing chemical oxidation demand from 50,000 milligrams a litre to less than 100 milligrams a litre. This meets the rigorous effluent discharge standards set by Chinese authorities.
Design of the plant was part of the AusAID-funded Datong Cleaner Environment Project. GHD is working in joint venture with Hassall International and Hatch. The contract also covers training for staff at the city's Environmental Protection Bureau and its Water Resources Management office. Demonstrations of more effective environmental management, particularly cleaner production principles, were also provided at the Datong Coal Gasification Company.
