螺旋对称流厌氧反应器常温下的运行特性
Operational characteristics of spiral symmetry stream anaerobic bioreactor under room temperature
摘要
Abstract
A maximum organic loading rate of 361.5kgCOD/(m3·d) is achieved in spiral symmetry stream anaerobic bioreactor(SSSAB) under mesophilic condition(35℃). However,the performance and sludge features,which require further research,are still unclear under room temperature(10—30℃). In comparison to three compartmentalized anaerobic bioreactor(TCAB) and upflow anaerobic sludge blanket reactor(UASB),the performance and sludge features were studied with same operational conditions under room temperature. The results showed that:the average COD removal efficiency of SSSAB(88%) was higher than that of TCAB and UASB(80% and 78%). The first-order kinetic constant of SSSAB was 5.4d–1,higher than that of TCAB (3.6d–1)and UASB(2.2d–1). In macro scale,compared with that from TCAB and UASB,the anaerobic granular sludge from SSSAB was clearer,more black and denser. Moreover,the surface ofanaerobic granular sludge from SSSAB was rough and full of channels. The total amount of extracellular polymeric substance(EPS) of anaerobic granular sludge from SSSAB was higher than that of TCAB and UASB,which provided conditions for mass transfer between sludge and substrates. The protein(PN)/ polysaccharide(PS)ratio of the sludge from SSSAB was lowest,which might indicate that it had more favorable strength and settling ability. The distribution of flocculability of the sludge from SSSAB was more reasonable,and its fluctuation was smaller compared with that from UASB.关键词
