摘要
为了使共厌氧消化技术在实际生产中得到应用,研究了广泛使用的絮凝剂阳离子聚丙烯酰胺(PAM)对剩余污泥与酒精糟液高温共厌氧消化的影响,并考察了不同搅拌强度消除PAM的影响。结果表明,阳离子PAM的含量越高,对共厌氧消化反应影响越明显,相对高的搅拌速度有利用消除高分子PAM对质子传输的束缚作用,增加厌氧微生物与污泥的接触机会,从而有利于厌氧微生物对有机物的降解,但不利于污泥大颗粒的形成。
In order to apply anaerobic codigestion in industry,effect of cation PAM addition on anaerobic thermophilic codigestion of waste activated sludge and waste wine distillery was investigated,the relief influence of PAM addition by mixing intensity was discussed.Results showed that the more the concentration of PAM addition,the more of influence on anaerobic codigestion.Higher mixing intensity is benefit to the binding mass transfer by PAM and to increase contact chance between microbe and sludge,hence for the benefit to the degradation of organic matter,but is not benefit to sludge granular.
