Introduction Waterpollutionhasbecomeanurgentissueworldwidewiththeincreaseofindustrialization,urbanization,andpopulationgrowth.Naturalwetlandsplayavitalroleinpurifyingwater,butthenaturalwetlandsareusuallyscarceandfragile.Therefore,artificialwetlands,asanalternativesolution,arebecomingmorepopular.TheMaozhouRiverartificialwetlandprojectisatypicalexampleofwaterpollutioncontrolinChina.TheprojectaimstotreatwastewaterandimprovethewaterqualityoftheMaozhouRiver. Methods TheMaozhouRiverartificialwetlandcoversanareaof130,000squaremeters,whichconsistsofthreeseparatewetlands.Themainfunctionofthewetlandistotreatthesewagefromthesurroundingarea.Thewetlandisdesignedwithaseriesofphysicalandbiochemicalprocesses,includingsedimentation,filtration,plantabsorption,andmicrobialdecomposition.Thewetland'soperationiscontrolledbyacompletesetofautomaticcontrolequipment,includingwaterlevelmonitoring,flowregulation,andbiologicaltreatment.
