【摘要】：针对分散式生活污水进水分散、冲击负荷较大等特点,设计了1种主要用于处理分散式生活污水的新型一体化生物反应器,并研究了该一体化反应器的处理效能,探讨了污染物去除机理。结果表明,系统对COD、TN、TP的去除率分别为83%、74%、76%,处理效率较传统的OCO工艺均有所提高。经过分析认为,一体化反应器构型结构紧凑、占地省、沉淀池入口处可调挡板可调节系统内部运行参数之间的相对平衡,混合区内部循环流态存在较少的局部积泥区。同时该工艺中的污泥性能良好,具有良好的抗冲击负荷能力,活性污泥中微生物种群丰富且具有较好的稳定性。
[Abstract]:A new type of integrated bioreactor was designed for the treatment of dispersed domestic sewage. The efficiency of the integrated reactor was studied and the removal mechanism of pollutants was discussed. The results showed that the removal rate of COD / TNTP by the system was 837 / 7476% respectively. The treatment efficiency is improved compared with the traditional OCO process. It is concluded that the integrated reactor is compact in configuration and less in space. The adjustable baffle at the inlet of the sedimentation tank can adjust the relative balance between the internal operating parameters of the system, and there is less local sludge area in the internal circulation flow state in the mixing zone. Meanwhile, the sludge performance in this process is good. The activated sludge is rich in microbial population and has good stability.

【正文快照】： 据国家发改委统计,截止2010年底,我国城市污水处理效率已达77.4%,县镇污水处理率为60.1%,建制镇污水处理率仍不足20%,而农村的污水处理设备近乎空白[1]。我国城市与村镇污水处理率差距较大,小城镇污水治理相对非常滞后。对于城市污水收集管道难于延伸的区域(如农村、小城镇、
