SBR法处理废水的影响因素   总被引:7,自引:0,他引:7  
系统评述了曝气方式,溶解氧浓度、温度等操作条件和pH值、废水中的营养物及其他物质等基质条件对SBR法处理废水效果的影响。在总结前人经验和我们实验的基础上得出:对于SBR法渐减曝气更合理、更经济;保持出水水质前提下,SBR法处理废水溶解氧浓度在一定程度是可以减小的,从而减少能耗;SBR法可操作的温度范围很宽,相应的适应菌群有所不同;SBR法对pH值、部分金属离子以及硫酸根有很强的耐冲击能力。SBR法处理废水对营养物的需求,各种因素之间的相互作用等问题还有待进一步研究,文章就此对以后的研究工作提出了建议。  相似文献

The effects of different substrates on the aerobic granulation process were studied using laboratory-scale sequencing batch reactors (SBRs). Four parallel granules sequencing batch reactors (GSBR): R1, R2, R3, and R4 were fed with acetate, glucose, peptone and fecula, respectively. Stable aerobic granules were successfully cultivated in R1, R2, R4, and smaller granules less than 500 μm were formed in R3. Morphology and the physic-chemical characteristics of aerobic granules fed with different carbon substrates were investigated by the four reactors operated under the same pressure. The aerobic granules in the four reactors were observed and found that peptone was the most stable one due to its good settleability even after a sludge age as short as 10 d. A strong correlation was testified between the characteristics of aerobic granules and the properties of carbon substrates. The stability of aerobic granules was affected by extracellular polymer substances (EPS) derived from microorganism growth during feast time fed with different carbon substrates, and the influence of the property of storage substance was greater than that of its quantity. Optimal carbon substrates, which are helpful in the cultivation and retention of well-settling granules and in the enhancement of the overall ability of the aerobic granules reactors, were found.  相似文献

采用厌好氧交替的SBR反应器培养好氧颗粒污泥,研究不同运行调控方式形成的好氧颗粒污泥性质的差异。结果表明,通过进料负荷和沉降时间的调控,都可以实现好氧污泥完全颗粒化。通过进料负荷调控培养出的好氧颗粒,污泥浓度大,颗粒周围原后生动物丰富,颗粒存在核心,从中心到表面有明显分层;使用短沉降时间调控培养出的好氧颗粒污泥,颗粒粒径均匀,表面有丝状微生物伸出,污泥浓度较小,颗粒周围少见原后生动物,颗粒从中心到表面无明显分层。两种颗粒的微生物分布具有相似性,即颗粒表面多为杆菌,中心以球菌为主。两种颗粒形成过程中,污泥浓度变化很大,但污泥均保持较高的沉降性,污泥良好的沉降性是形成好氧颗粒污泥的必要前提。  相似文献

为考察自养脱氮污泥亚硝化活性快速恢复的策略,在3个反应器内分别采用不同的方法对经过长期冷冻保存后的污泥进行了恢复活性的研究.其中R1为MBR(膜生物反应器),采用低ρ(DO)(0.30 mg/L)连续流恢复策略;R2为SBR(序批式反应器),采用低ρ(DO)(0.30 mg/L)间歇流恢复策略;R3为SBR,采用低ρ(NH4+-N)预培养-高曝气-低ρ(DO)运行三阶段的恢复策略.结果表明,R1的恢复时间为46 d,NH4+-N氧化速率达到4.99 mg/(h·g)(以N计),最终ρ(MLSS)达到5.43 g/L;R2的恢复时间为39 d,NH4+-N氧化速率达到4.61 mg/(h·g),最终ρ(MLSS)达到4.47 g/L;R3的恢复时间为48 d,NH4+-N氧化速率达到5.64 mg/(h·g),最终ρ(MLSS)达到5.16 g/L. 3个反应器均能长期抑制亚硝酸盐氧化细菌的活性,使亚硝化稳定运行. 3个反应器中,R3恢复所需时间最长,但污泥活性最好; R1中的污泥活性较低,但是膜组件有效截留了污泥,达到了最高的ρ(MLSS).研究显示,通过厌氧预培养后转为膜生物反应器连续流运行的策略,可有助于污泥的极大保留及污泥活性的最大恢复.   相似文献

To investigate the microbial communities of microorganisms cultivated under different carbon sources, three sequencing batch reactors were operated. They were supplied with sewage, glucose and sodium acetate as carbon sources respectively and showed high phosphorus removal performance. The results of denaturing gradient gel electrophoresis(DGGE) of polymerase chain reaction-amplified (PCR) 16S rDNA fragments demonstrated that β-protebacteria, Actinomyces sp. and y-protebactefia only exited in 1# reactor. The microbiological diversity of 1# reactor exceeded the other two reactors. Flavobacterium, Bacillales, Actinomyces, Actinobacteridae and uncultured bacteria(AF527584, AF502204, AY592749, AB076862, AJ619051, AF495454 and AY133070) could be detected in the biological phosphorus removal reactors.  相似文献

Three sequencing batch reactors supplied with different carbon sources were investigated. The system supplied with glucose gained the best enhanced biological phosphorus removal although all of the three reactors were seeded from the same sludge. With the measurement of poly-β-hydroxyalkanoate (PHA) concentration, phosphorus content in sludge and extracellular exopolymers (EPS) with scanning electron microscopy (SEM) combined with energy dispersive spectrometry (EDS), it was found that the biosorption effect of EPS played an important role in phosphorus removal and that the amount of PHA at the end of anaerobic phase was not the only key factor to determine the following phosphorus removal efficiency.  相似文献

The feasibility of the nitrous organic wastewater treated was studied in seven anaerobic sequencing batch reactors(ASBRs) (0^#-6^#) which had been run under stable anaerobic ammonium oxidation (Anammox). By means of monitoring and data analysis of COD, NH4^#-N, NO2^--N, NO3^--N and pH, and of microbial test, the results revealed that the optimal Anammox performance was achieved from 2^# reactor in which COD/NH4^+ -N was 1.65, Anammox bacteria and denitrification bacteria could coexist, and Anammox reaction and denitrification reaction could occur simultaneously in the reactors. The ratio of NH4^+-N consumed : NO2^- -N consumed : NO3^- -N produced was 1:1.38:0.19 in 0^# reactor which was not added glucose in the wastewater. When different ratio of COD and NH4^+-N was fed for the reactors, the ratio of NO2^- -N consumed: NH4^+-N consumed was in the range of 1.51-2.29 and the ratio of NO;-N produced: NH4^+ -N consumed in the range of 0 -0.05.  相似文献
