Chaoyang district will complete its treatment of the Xiaotaihou River, the earliest man-made river in Beijing, by the end of June 2017, and is expected to thoroughly purify 33 black-odor rivers by the end of 2017, according to an announcement made at the two sessions of Chaoyao district.
The clean-up efforts for the Xiaotaihou River started in 2016. The river, which used to flood the screen with an image of turbid and foul water, is expected to be transformed to a green culture leisure corridor in June 2017.
By then, the quality of the water can be classified as IV-grade, suitable for industrial use and other amusement purposes as long as it doesn't directly contact skin. There will be a 3.4 km-long passageway for people to sail. Additionally, four cultural landscape areas and 22 sightseeing spots will be constructed along the river to showcase the waterfront ecology as well as distinctive history and culture.
The transformation process used on the Xiaotaihou River will be reproduced with another 33 rivers. By initiating wastewater control in 33 black-odor rivers this year, wastewater that runs in 19 river sections must be eliminated. And the whole project will be finished by the end of 2017.
Two methods have been adopted in refining the water quality. Part of the wastewater is processed in large treatment plants, with an average daily processing capacity of 2,880,000 cubic meters.
The other part goes to scattered small treatment plants or equipment. For instance, an integration of a sewage treatment reaction pool has been installed at Xinbao Village as a pilot project. With help of this new, space-saving processing container, wastewater treatment for a particular area can be done locally. About 100 cubic meters of water can be processed per day at lower power consumption.
Furthermore, in 2017, a 110-kilometer pipeline for collecting sewage water and an 18-kilometer pipeline for confluence of rainwater and sewage will also be constructed.
To better implement the clean-up work next year, Chaoyang government will apply an accountability system by assigning specific work to officials in the district, villages, and communities, and will be monitoring and evaluating the results of clean-up work.
