PIPE LINE PURIFYING DEVICES AND CONNECTING STRUCTURE FOR PIPE LINE PURIFYING DEVICES

摘要

The present invention is to provide an in-pipe purification apparatus which can purify sewage at low cost and with high efficiency. Further, the present invention is to provide a connection structure of in-pipe purification apparatuses, which structure can realize both excellent flowing performance and excellent purifying performance. The in-pipe purification apparatus according to the present invention includes a volume flow rate-securing section which secures a volume flow rate of water and which has water permeability, and a water purification section which is located below the volume flow rate-securing section and which purifies water supplied from the volume flow rate-securing section, the volume flow rate-securing section having an opening section through which the water is supplied from the volume flow rate-securing section to the water purification section.
