摘要:
研究了三价砷As(Ⅲ)对序批式反应器SBRs系统中活性污泥的影响.采用反应器R1和R2(对照CK)进行对比试验,向RI中逐渐添加不同浓度的三价砷As(Ⅲ),定期检测两组反应器内活性污泥性状和出水水质.结果表明,整个实验过程中R1系统对COD去除率维持在90％左右,比R2系统低大约5％；随着三价砷浓度的提高,R1系统内污泥絮体直径变小且分散,SVI30由原来的37 mL/g提高至97mL/g,可能是部分微生物中毒引起絮体分解所致；与R2系统相比,Rl内微生物种类相对单一,特别在高浓度三价砷(20 mg/L)条件下,后生动物消失.
Abstract:
This paper studies the effect of As ( Ⅲ ) on the activated sludge in the sequencing batch reactorsystem. Rl and R2 ( control CK) were installed for contrast test. As( Ⅲ ) was increasingly added in R1 andthe activated sludge character and effluent quality were termly tested. The results showed that COD removalrate of Rl maintained at ca.90% which is 5% lower than that of R2. With stepwise augmentation of As(III), the flocs became disperse and tiny , SV130 increased from 37 mL/ g to 97 mL /g , which was proba-bly due to the decomposed structure of flocs caused by partial microorganisms poisoning.Compared with R2,the microbiological diversity was relatively simple,especially the protozoa disappeared under the high concen-tration of As().
