RESEARCH ON DENITRIFICATION OF SLUDGE BIOGAS SLURRY BY COAGULATION-SBR PROCESS

Yuan Jigang Guan Xiuqiong,

摘要: 采用混凝-SBR法处理污泥发酵产生的沼液,研究了混凝-SBR法对污泥沼液的脱氮效果和影响因素。结果表明:SBR在进水C/N为1.5,曝气时间8 h,反硝化补充C/N(COD与总氮的比值)为0.25时,其总氮去除率可达78.8%。沼液经过混凝-SBR法处理后,总氮去除率大于80%,其出水ρ(TN)小于100 mg/L,可用于发酵料液的配制,实现污泥沼液脱氮回用的目的。

Abstract: This paper used coagulation-SBR process to treat biogas slurry generated from fermentation of sludge，and investigated the denitrification effects and conditions of coagulation-SBR process． The results indicated that when C/N of inflow was 1. 5，aeration time was 8 h，and additional C/N of denitrification was 0. 25 in SBR，the total nitrogen removal rates could reach 78. 8%． Moreover，after coagulation-SBR process，the total nitrogen removal rates of biogas slurry was greater than 80% and the total nitrogen value of effluent was less than 100mg /L． In addition，after coagulation-SBR process，the effluent of biogas slurry could be reused and applied in the preparation of fermentation liquor．
