摘要
解决污泥问题的最好办法就是污泥减量。研究了两种强氧化剂过氧乙酸(PAA)和Fenton试剂对污泥的溶解特性。研究表明PAA与Fenton试剂对污泥都有一定的减容效果,相比而言,Fenton试剂对污泥的减容效果更为显著。PAA溶解污泥的极值时间为2 h,Fenton试剂溶解污泥的极值时间为0.5 h。在加入1 mol/L的NaOH,至污泥液pH=10的前提下,PAA和Fenton试剂对SS(suspend solid)的减少率分别高达65.4%,87.8%。
Sludge reduction is the best way to solve sludge problem in wastewater treatment. Two strong oxidants, peracetic acid（PAA） and Fenton reactant（H2O2 ＋ Fe^2 ＋ ）, were used to evaluate the dissolve characteristics of sludge reduction. Results showed both PAA and Fenton reactant could reduce sludge. Efficiency of Fenton reactant was better than that of PAA on sludge reduction. Optimal time on sludge redution by PAA was 2 h, while by Fenton reactant was 0.5hr. Under condition of adding 1mol/L NaOH for adjusting pH to 10, SS reduction rates by PAA and Fenton reactant were 65.4 % and 87.8 %, respectively.
