物が処理水中に放散されるためであると推定される。As shown in Table 3, in the water quality improving material of the present invention, in each of the first to fourth water passages, the amount of sodium hypochlorite was increased as the accumulated water flow increased. Adsorption and capture capacity are reduced, but water supply is stopped for a predetermined number of days and then water supply is resumed (at the start of the second, third, and fourth water supply)
It was confirmed that the adsorption and capture ability of sodium hypochlorite was restored. This is because during the suspension of water flow, silicate bacteria present in the water quality improvement material decompose the adsorbed and captured substances such as sodium hypochlorite, and the decomposed products are released into the treated water. Is estimated.
