Although such a conventional method has no particular problem as long as it has only a purification function, it naturally requires a site for the installation of water treatment facilities around the river, and the installation of water treatment facilities also makes it possible to create a natural landscape. There is something inadequate in that Furthermore, there are some insufficient purification treatments that are more natural. In other words, since purifying a river is often intended to restore nature, it is desirable to purify the river in a state that is as close to the original function of nature as possible. On the other hand, there are some that are not sufficient in that they act externally and have the elements that impair the natural landscape as described above.

The high anaerobic condition is the immersion of the assimilation substance in water and further It is formed by the consumption of oxygen by aerobic bacteria that propagate temporarily by utilizing assimilation. Then, in the assimilation block under a high anaerobic condition, nitrate nitrogen is converted into ammonia nitrogen and nitrogen gas (N 2 ) by the following three kinds of processes that coexist.

る。The conversion to ammonia nitrogen is based on the anaerobic condition in the assimilation block and the reduction based on the biological activity of the bacteria capable of reducing nitrate which propagates by utilizing the assimilation, and the high anoxic condition in the assimilation block. In other words, it proceeds by pure chemical reduction at a high reduction level. These reduction processes are indicated as NO 3 − → NO 2 − → N 2 O → NH 4 − .

It is adsorbed without being redissolved in the material. On the other hand, nitrogen gas is released into the atmosphere.

利点もある。As the assimilation material used in the assimilation layer, one that can not only serve as a nutrient source for the bacteria but can also provide a favorable home for the bacteria is used. As such, dead plants are most suitable. That is, the dead plants contain a large amount of organic substances suitable as a nutrient source for bacteria and provide a comfortable place for bacteria due to their micropore structure. In addition to the advantage that the use of dead plants is easy, including the economic meaning,
For example, rice straw, old tatami mats, or used scallops of shiitake mushrooms,
Furthermore, there is an advantage that it can lead to effective utilization of pruned dead branches and the like.
