Municipal drainage method
The invention discloses a municipal drainage method. The municipal drainage method comprises the steps that when raining, rainwater is primarily filtered through a second cover plate on a box culvert and then enters the box culvert, and the rainwater is secondarily filtered through a filter screen; the rainwater filtered through the filter screen flows into a fine sand settling pond, and intercepted coarse sand flows into a sand accumulating tank at the bottom of a coarse sand settling pond; the rainwater in the coarse sand settling pond is primarily settled, filtered through first filter holes in a first flow guide wall and then enters the fine sand settling pond; the rainwater in the fine sand settling pond is secondarily settled, filtered through second filter holes in a second flow guide wall and then enters a sludge settling pond; and the rainwater in the sludge settling pond moves upwards, is settled in a settling pipe three times and then flows into a drainage pipe. According to the municipal drainage method, sand grains of different specifications in the rainwater are filtered through the coarse sand settling pond, the fine sand settling pond and the sludge settling pond which are sequentially arranged, the sand grains are effectively prevented from entering the drainage pipe, and a sewer is prevented from being blocked.
本发明公开了一种市政排水方法，包括：下雨时，雨水经过箱涵上的第二盖板的初次过滤后进入箱涵内，过滤网对雨水进行二次过滤；过滤网过滤后的雨水流入细砂沉淀池，截留下来的粗砂流入粗砂沉淀池池底的积砂槽；粗砂沉淀池中的雨水经过初步沉淀后，通过第一导流墙上的第一过滤孔的过滤，进入到细砂沉淀池中；细砂沉淀池中的雨水经过二次沉淀后，通过第二导流墙上的第二过滤孔的过滤，进入到污泥沉淀池中；污泥沉淀池中的雨水向上移动，在沉淀管内进行三次沉淀后流至排水管中。本发明市政排水方法，通过依次布设的粗砂沉淀池、细砂沉淀池和污泥沉淀池，对雨水中不同规格的砂粒进行过滤，有效阻止砂粒进入排水管，防止下水道的堵塞。
