摘要：

In　current　paper,　compared　to　the　conventional　coagulation,　micro-sand(MS)　and　magnetic　powder(MP)　ballasted　flocculation　were　investigated　during　the　treatment　of　micro-polluted　surface　water　by　simulating　Actiflo™　and　Sirofloc™　process.　Under　an　optimized　operation　condition,　the　optimal　turbidity,　CODMn　and　TP　removal,　94.5%,　75.1%　and　93.0%,　respectively　could　be　achieved　by　the　MP　process.　In　further　research,　pollutants　removal　efficiency　at　various　settling　time　(5,　10,　15,　20　min),　flocs＇　two-dimensional　fractal　dimension　and　average　size　were　simultaneously　studied　and　the　relationship　among　them　was　also　discussed.　©　(2014)　Trans　Tech　Publications,　Switzerland.
