流力を作用させる。According to the above technical means, there are the following actions. (Claim 1) When the flow velocity is equal to or lower than the normal velocity, the contact material for water treatment maintains an upright state due to the buoyancy of the floating body, and microorganisms adhering to the contact material for water treatment and organic substances mixed in industrial wastewater and domestic wastewater. Contact with solids and suspended solids causes continuous purification of water quality. On the other hand, if the water volume suddenly increases due to the influence of heavy rain, etc., or if the water volume suddenly decreases due to the opening of the weir installed downstream and the flow velocity changes significantly, the contact material for water treatment falls to the riverbed side and is used for water treatment. Riverbed deposits and attached dust that have been purified by the contact material and settled are subjected to hydrodynamic force. (Claim 2) A desired amount of water is continuously discharged from the water discharge port, and the lower water pressure of the shaft support portion is higher than the upper water pressure to form a standing weir. When the lower water pressure acting on the water stop plate below the shaft support due to heavy rain etc. and the water stop pressure greater than the total force of the balancer act on the water stop plate above the shaft support, the balance is lost. , The water stop plate falls and flows the water flow downstream, winds up the riverbed sediments downstream of the water stop plate, and causes suspended suspended solid substances to flow vigorously downstream. At that time, since the volume of water is drastically reduced, the upstream water treatment contact material group falls to the river bed side as in the case of claim 1 and becomes riverbed sediments and adhered dusts purified by the water treatment contact material. Apply water flow force.

(Claim 1) When the flow velocity is higher than normal, there is no matching relationship between the floating body and the water pressure, and the water treatment contact material group, which is purified by the contact action with adhering microorganisms, is laid down on the riverbed. Immediately when the water is released and the weir is released and discharged, the water treatment contact material group is laid down close to the river bed to prevent the resistance of the effluent and continuously purify the water during normal times. It is possible to provide a purification device of a structure installed in a river that is simple and inexpensive. (Claim 2) A desired water stop volume due to the mutual balance between the position of the shaft support and the weight of the balancer, for example, a water stop plate that automatically falls when the balance is upset when water is about to overflow. Since some or all of the transverse weirs that are installed at intervals are formed, and the water treatment contact material group is provided on the upstream side of the weirs, in addition to continuation of water purification by adherent microorganisms, water quality riverbed deposit containing sediment is left by purification, washing stream of dust such adhering to for water treatment contact member
It is possible to provide a purification device rivers smoothly performed by effectively utilizing the natural force automatically discharged teeth.

In the normal state, since the water depth is constant as shown in FIG. 7, the water treatment contact materials 1 ... The organic substances in domestic wastewater and industrial wastewater mixed in the river water are captured by each water treatment contact material 1 ... While being decomposed and purified by the contact action with the attached microorganisms to be deposited on the riverbed a as the riverbed sediment 100. , Relatively large dust is contact material 1 for water treatment ...
There is no difference from the above-mentioned example. When the volume of water increases due to heavy rain or the like, a lower water pressure than the shaft support 13a and a water pressure larger than the total force of the balancer 23 act on the water stop plate 13 above the shaft support 13a to balance the water. When the water stop plate 13 collapses and the stop water flows down to the downstream side, each water treatment contact material 1 falls down to the river bed a in the direction of the downstream river bed a so as to be buried in the river bed sediment 100. The flow stop plate 13 rises again when the water level becomes shallower to a lower level than the shaft support 13a, and only the bottom end of the projection 33 is lifted. Upon collision, the water blocking plate 13 naturally returns to the initial state, and along with that, the clean water treatment contact materials 1 ...
