摘要:

在温度35 ℃、pH=10条件下，对比研究了14 d内剩余污泥在KOH、NaOH、Ca(OH)2和Na2CO3这4种碱性条件下的水解产酸性能、脱水性能、氨氮和正磷酸释放情况以及污泥减量情况。结果表明：剩余污泥在4种碱性条件下表现出不同的水解产酸能力、脱水性能、以及污泥减量情况。污泥水解能力排序为Na2CO3 > NaOH ≈ KOH > Ca(OH)2；产酸能力排序为NaOH > KOH ≈ Na2CO3 > Ca(OH)2；脱水性能排序为Ca(OH)2>Na2CO3 > NaOH ≈ KOH，氨氮和正磷酸盐释放量排序均为为Na2CO3 > NaOH ≈ KOH > Ca(OH)2。剩余污泥在Na2CO3 条件下挥发性悬浮固体(VSS)去除率最高；但在NaOH条件下总悬浮固体(TSS)去除率最高。

Abstract:

The hydrolysis and acidification abilities, dewaterabilities and sludge reduction of waste activated sludge (WAS) under four types of alkaline conditions, which were KOH, NaOH, Ca(OH)2 and Na2CO3, were investigated. Temperature and pH value were controlled at 35 ℃ and 10 respectively for all alkaline conditions investigated. WAS demonstrated different hydrolysis abilities, acidification abilities and dewaterabilities under the four types of alkaline conditions. The order of WAS hydrolysis abilities, acidification abilities, ammonia and phosphorus release, dewaterabilities under the four types of alkaline conditions were Na2CO3 > NaOH ≈ KOH > Ca(OH)2,, NaOH > KOH ≈ Na2CO3 > Ca(OH)2, Na2CO3 > NaOH ≈ KOH > Ca(OH)2 and Ca(OH)2,>Na2CO3 > NaOH ≈ KOH, respectively. Volatile suspended solid (VSS) reduction of WAS was the best under Na2CO3 condition; while under NaOH condition total suspended solid (TSS) reduction was the best.
