China develops technologies to control water pollution
water pollution control project is divided into five main aspects: technologies that are used to solve water pollution in lakes and restore their ecological environment, technologies used to improve water quality in cities, technologies to guarantee the safety of drinking water, and new technologies on biological treatment of water, and on forming waste water handling equipment into a complete set. The major achievement includes technologies can be used to improve overall aquatic environment at lake sources, and restore the ecological environment for lakes after they are heavily polluted. These technologies are regarded as key technologies in solving the lake pollution problem. The technologies are have been put to use in 11 cities including Wuhan and Suzhou, and different schemes made that can improve the water quality in these cities based on their specific situation.
research team on the water pollution control project said some technologies have begun to produce good results, and some have been used in handling the Songhuajiang River pollution incident that occurred last year. In future, these technologies will be applied in solving the water pollution problems in areas such as the Three Gorges dam, the South-to-North Water Diversion Project, Taihu Lake, and Huaihe River reaches.
big technology program was initiated in 2002.
Chinese central government invested 350 million yuan for the project and another
700 million yuan was gathered from local governments and related social
institutions. So far, applications for patents for over 400 technologies in the
program have been filed, 14 sets of criteria have been made to control various
kinds of water pollution, four R centers established, and more than 100
big modeling projects established from the program.
