Strategy of environment protection in China
Key contradiction in China 中国社会的主要矛盾
The contradiction between unbalanced and inadequate development and
the people’s ever-growing needs for a better life.
人民日益增长的美好生活需要和不平衡不充分的发展之间的矛盾
Environment pollution is a major element of the unbalanced
development.
环境污染是这种矛盾的主要体现之一。

Three key time for China’s future: 2020, 2035, and 2050.
2020: Build a moderately prosperous society in all respects.
2035: Socialist modernization is basically realized.
2050:Develop China into a great modern socialist country that is
prosperous, strong, democratic, culturally advanced, harmonious, and
beautiful.

Strategy of Environment Protection
2020: Tough battle again pollution control for serious pollution issues.
2035: Environmental and ecological quality are overall improved, and
the goal of building a Beautiful China is basically attained.
2050: Beautiful China initiative is entirely achieved with improved
environmental quality and governance system.

Seriously polluted urban rivers/lakes are focus of water environment
improvement in 2018-2020
 By 2017, the number of seriously polluted rivers/lakes are reduced by 90% in
municipality cities and provincial capitals and reduced by 60% in prefectural-
level municipalities.
 By 2020, the number of seriously polluted rivers/lakes in prefectural-level
municipalities will be reduced by 90% and should be eliminated by 2030.

Technical demands of water environment protection

17. 2018/6/26 17
Key technical demands
(1) Municipal wastewater treatment
up-to-date wastewater treatment technology, energy-resources-environment sustainable WWTP
(2) Industrial wastewater treatment
treatment of refractory organic substances (ROS)
(3) Water quality improvement and ecological restoration of polluted rivers/lakes
Integrated water quality improvement and ecological restoration technologies
(4) Rural domestic wastewater treatment
Decentralized treatment technologies and equipment
Technical demands of water environment protection

18. 2018/6/26 18
Major weakness of the industry
(1) Technical evaluation and study are inadequate
(2) The treatment is lack of integrity
(3) Public interest of the environment vs. commercial feature of the industry
(4) Technical capacities are generally weak
(5) Protection of intellectual property
Technical demands of water environment protection

19. 2018/6/26 19
Broad opportunities for international corporations
(1) Cutting-edge water treatment technologies: aerobic granulate, anammox, and
new Membrane bioreactor
(2) Sustainable WWTP: environment-economic-social sustainability
(3) Smart Water: Integration of AI and water industry
(4) Treatment of emerging contaminants: risk assessment, monitoring, and
treatment
(5) Ecological restoration: watershed-scale restoration, nature-based solution
