Influence of Different Components Ratio on the Performance of Controlled-release Carbon-source Material
Controlled-release carbon-source material of GSP-ABN contained corn starch as carbon source(S) and polyvinyl alcohol(P)as vector,as well as modifying with boric acid(B),attapulgite(A) and sodium sulfate(r).Nine kinds of GSP-ABN were prepared according to different components ratio.Nitrogen removal effect and TOC accumulation level were investigated when adding these nine kinds of materials in a static denitrifying experiment.The results showed that,different components ratio in material had a significant influence on TN removal effect and TOC accumulation level.The best technological condition of preparing GSP-ABN was finished by orthogonal design,it was that mass ratio of P to S,Ato S,and B to S was respectively 1.5,0.25 and 0.25.
