高铁酸盐对剩余活性污泥的氧化水解效能

针对高铁酸盐的强氧化性,提出利用高铁酸盐进行污泥氧化的实验研究.结果表明,高铁酸盐能够有效地破坏活性污泥的絮体结构,对初始浓度为12 600 mg·L^-1的活性污泥,m（Fe）/m（SS）=0.40μg/mg的高铁酸盐能够使活性污泥的絮体全部解体.MLVSS随高铁投加量的增加下降,并呈线性相关.随高铁酸盐投加量的不同...

Efficacy of Ferrate Oxidation and Hydrolyze Remnant Activated Sludge

Using ferrate oxidized remnant activated sludge base on that ferrate hold strong oxidation capability. The results showed that: ferrate could destroy activated sludgy structure, when initial activated sludge concentrations was 12 600 mg x L(-1), m (Fe)/m (SS) = 0.40 microg/mg. Ferrate made activated sludge floccules desegregations with increase of ferrate concentration the MLVSS went down. With different ferrate was put in, the different concentration activated sludge had different dissolving characteristic; the much higher initial concentration that activated sludge had, the much more SCOD, NH4(+) -N, TP was released. When activated sludge was 12 600 mg x L(-1), ferrate was m(Fe)/m(SS) = 0.40 microg/mg,the activated sludge released the maximum concentration SCOD, NH:(4+)-N, TP. The liquid from sludge hydrolyze was treatment with waste water. The cost of sludge treatment is just 0.25 yuan/t that is lower than the sludge traditional treatment.
