Artificially intensified water purification technology and bank revetment plan for river

The artificially intensified water purification technologies applied to the water improvement of the polluted river at home and abroad are summarized herein,and then the technologies with good prospect of popularization in China,i.e.the gravel contact oxidation process and the ecological floating island,are emphatically expatiated with the analysis on the actual case.Furthermore,a new concept for purification of the polluted water,that is,the water purification technology must be combined with the water project under construction,is put forward and a structure plan of the bank revetment built with stone cage for water purification is recommended as well.
