The separation methods of oily flavoring substances from tail water of Luzhou-flavor liquor were introduced.

After it caused water supply crisis in Wuxi city,the state made more stringent emission requirements to the Taihu lake basin urban wastewater treatment firm of tail water,many urban wastewater treatment finns are facing upgradeing of the removal of nitrogen and phosphorous technology.

Choice of temporary closure scheme of tailwater of Langshitan Hydropower Plant in construction period;

The combined constructed wetland process of aerated biological enhanced oxidation,three-stage surface flow wetland,two-stage subsurface flow wetland and biological stabilization pond was used to treat the tailwater from municipal WWTP.

Consequence analysis of effects on water environment of surface water heat pumps discharges

Based on the former results,this paper summrized research progress of thermal discharge for water environment,including the research of numerical simulation, influence on hydrobionts and tenor of eutrophication.
