摘要：

To　study　the　effects　of　sulfur/sponge　iron　ratio　on　denitrification　and　phosphorus　removal,　a　series　of　static　experiments　were　conducted　using　different　ratios　of　sulfur　and　sponge　iron.　The　results　showed　that　the　denitrification　and　phosphorus　removal　effect　of　sulfur/sponge　iron　composite　fillers　was　significantly　higher　than　that　of　single　filler,　and　sulfur/sponge　iron　ratio　was　one　of　the　key　factors　influencing　nitrogen　and　phosphorus　removal　by　composite　fillers.　When　the　volume　ratio　was　equal　to　or　greater　than　1:1,　the　removal　efficiency　of　TN　and　TP　reached　85%　and　97%,　respectively.　The　denitrification　and　phosphorus　removal　process　of　the　composite　fillers　both　fitted　second-order　kinetic　equation,　the　denitrification　was　dependent　on　heterotrophic　denitrification　and　sulfur　autotrophic　denitrification;　the　phosphorus　removal　was　mainly　chemical　phosphorus　removal　caused　by　sponge　iron　corrosion.　©　2016,　Science　Press.　All　right　reserved.
