摘　　要：将脉冲布水技术和复合水解工艺相结合,开发了间歇膨胀复合厌氧反应器。对复合厌氧/水解反应器的结构、运行参数、配水方式进行了阐述,讨论了间歇膨胀复合厌氧/水解反应器的污泥沉降性能及流态负荷与膨胀率的关系。分析结果表明,采用脉冲进水可提高反应器进水过程基质浓度、降低传质阻力,从而提高反应器反应速率及SS去除率;当平均上升流速<1 m/h时,直径<0.3 mm的颗粒污泥可有效保留在反应器内;当平均上升流速为0.45~0.88 m/h时,其膨胀率达到30%~80%,此时反应器为悬浮床反应器。目前该反应器已经应用于集中工业废水、综合城镇污水及制药废水治理,运行效果良好。An intermittent expansion anaerobic hybrid reactor was developed by combining pulse water distribution technology with hybrid hydrolysis process. The structure, operation parameters and wa- ter distribution mode of the intermittent expansion anaerobic hybrid reactor were expounded. The sludge settling property and the relationship between flow load and expansion rate were discussed. The results showed that intermittent expansion anaerobic hybrid reactor could increase the inlet substrate concentra- tion, reduce the mass transfer resistance, so as to improve the reaction rate and SS removal rate; when the average rising velocity was below 1 m/h, the granular sludge with diameter less than 0.3 mm could be effectively retained in the reactor; when the average rising velocity was in the range of 0.45 -0.88 m/ h, the expansion rate could reach 30% - 80%. At this time, the reactor was operated as suspended bed reactor. At present, the intermittent expansion anaerobic hybrid reactor was effectively used to treat in- dustrial wastewater, municipal composite wastewater and pharmaceutical wastewater.
