Current Situation and Countermeasures of Phosphorus-Containing Wastewater Treatment in Surface Treatment Industry

The excessive discharge of phosphorus-containing substances will lead to eutrophication of water bodies and cause water environmental pollution.Hence，the prevention and control of phosphorus pollution is one of the major issues in China ecological environment construction.In this paper，the treatment methods for removing phosphorus from phosphorus-containing wastewater such as chemical precipitation method，adsorption method，ion exchange method，membrane separation method and biological method were emphatically expounded，and the advantages and disadvantages of each method were compared and analyzed.Moreover，based on the concept of cleaner production，the countermeasures for the prevention and control of phosphorus-containing wastewater in the surface treatment industry were put forward from the three aspects of source control，phosphorus recycling，and automatic control.
