Artificial wetland helps improve water quality of Fenhe River
Workers are planting watergrass in an artificial wetland, in a bid to improve the water quality in Fenhe River in Qingxu County in north China's Shanxi Province. Water from the river will first be diverted into the 18-hectare wetland and be filtered by the grass before flowing back into the river.
The Fenhe River, the second-largest tributary of the Yellow River, was heavily polluted before, prompting the local government to take actions.
The wetland is also expected to serve as a public recreation area.
