The research and application of river control technology in foreign countries began with Japan, the
United States and some European countries in the 50s of 20th century. Their concept of river management
was the comprehensive control from the ecological protection and environmental governance, and
combined the engineering measures with water environment and social environment. The river ecorestoration
became an international hot spot after 1980s. China has entered the stage of comprehensive
river control and eco-restoration in the late 1990s, and has carried out much remediation work. But most
of them remain in the initial experiment. Proposals on the trend of river pollution remediation are finally
put forward.
To achieve health and sustainable development of the river ecosystem, the river should be treated by
bio-eco remediation as priority and the physico-chemical remediation as the assistant means.
Bioremediation materials should be optimized, and the bioremediation mechanism is studied from
different angles and hierarchical to improve the bioremediation technology further.
The general applied conditions of various technologies such as aeration, bio-film and microbial
preparation and dosing are determined.
The appropriate microorganisms are acclimated to adapt to different polluted river.
The river pollution control technique for urban area should be researched and studied.
