Sewage conveying system and pipeline sediment flushing method
The invention relates to the technical field of sewage treatment, in particular to a sewage conveying system and a pipeline sediment flushing method.The sewage conveying system comprises a sewage pipeline and a pipeline flushing mechanism, the pipeline flushing mechanism comprises a water conveying pipeline, a first control valve and a water pump, and the water conveying pipeline comprises a main pipeline; the other end is communicated with the sewage pipeline; the water pump and the first control valve are both arranged on the main pipeline, and the water pump is used for adjusting the water flow velocity in the main pipeline so that the water flow velocity in the main pipeline is not smaller than 0.5 m/s; the first control valve is used for connecting or disconnecting the main pipeline and the sewage pipeline, so that water flow with enough impact force is used for carrying out hydraulic scouring with certain strength on the sewage pipeline, and most of florae distributed in middle and surface layers of pipeline sediments can be scoured away; further, the reproduction metabolism and growth states of florae such as methanogens and sulfate reducing bacteria are destroyed, so that the release of harmful substances is reduced.
本公开涉及污水处理技术领域，尤其涉及一种污水输送系统及管道沉积物冲刷方法，污水输送系统包括污水管道和管道冲刷机构，管道冲刷机构包括输水管道、第一控制阀和水泵，输水管道包括主管道，主管道的一端与水源连通，另一端与所述污水管道连通；水泵和第一控制阀均设置在主管道上，水泵用于调节主管道内的水流流速，以使主管道内的水流流速不小于0.5m/s；第一控制阀用于对主管道与污水管道进行连通或者关断，从而通过具有足够的冲击力的水流流对污水管道进行一定强度的水力冲刷，使大部分分布于管道沉积物的中、表层内的菌群则会被冲刷掉，进而破坏了例如产甲烷菌和硫酸盐还原菌等菌群的繁殖代谢和生长状态，从而减少有害物质的释放。
