摘要:
针对现行SBR工艺设计中主要参数的选取仅凭经验或参照连续流系统的设计方法而忽视了序批式反应器自身生物降解的特点、造成设计计算上一定偏差的问题,以模拟生活污水为处理对象,在SBR反应器中对不同运行阶段的基质降解动力学过程进行了分析,推导出在缺/厌氧阶段以及好氧曝气阶段基质降解过程的动力学模型分别为S[aSi1S0]-5.654×10-6 Xt(缺氧/厌氧段)和S0101.662 5 10-5Xt(好氧段),同时提出了反应动力学参数的求定方法,并用实际运行数据对模型进行了有效性验证.结果表明,模型预测与实际SBR运行结果高度吻合、模型有效.这些模型为今后SBR工艺设计计算提供了适宜的设计...
Abstract:
Due to the lack of special designing model of sequencing batch reactor(SBR),the determination of basic parameters of the SBR has to depend on experience or refer to the design of continuous flow reactor in present, where its own characteristics of SBR has been ignored, resulting finally in some errors in the design. In order to solve the problem, the dynamic process of substrate biodegradation in different operation stage of the SBR treating synthesized domestic sewage was analyzed. Based on this, the dynamics models of substrate biodegradation were established according to anaerobic / anoxic (only mixing) stage and aerobic stage (aeration and mixing) of SBR operation. Selecting and determining method of the reaction kinetics’ parameters were proposed and discussed. The model was validated by data of performance of the SBR. As a result, substrate biodegrading model in anaerobic / anoxic stage is as S  [a ? Si  1 ?S0]?-5.654×10-6 Xt and that in aerobic stage S  ′ ? 101.662 510-5Xt. The results calculated by the models are highly consistent with that of performance of the reactor. The models are considered to be helpful for designing SBR applied to domestic wastewater treatment.
