Since the wastewater from the artificial dialysis is already stored in the storage tank 3, when the aqueous sodium hypochlorite solution is sent out into the storage tank 3,
By adding tap water from the water pipe 13 into the liquid storage tank 3, neutralization of the waste liquid in the liquid storage tank 3 is achieved.

の利点がある。In the above-mentioned example, the cold water stone 7
Crushed stones, but any natural rock mainly composed of calcium carbonate may be used. Examples of such natural rocks include crystalline limestone such as marble. The particle size of the natural rock loaded in the acid neutralization tank 2 is at most 3 cm, preferably 0.5 to 1.5 cm.
It is. When the natural rock particles have such a particle size, the handling is convenient, the contact area with the waste liquid is appropriate, the gap between the natural rock particles is appropriately provided, and the flow of the waste liquid is not hindered. There is an advantage that the neutralization action has a long life.
【００１８】酸中和槽２内を流通させる廃液は、酸中和

方、上方にある寒水石の粒径はさほど小さく成らないの
で、酸中和槽２の内部空間で目詰まりを起こすことがな
い。The waste liquid flowing through the acid neutralization tank 2 is preferably flowed from below to above the acid neutralization tank 2, but may be flowed from above to below. Acid neutralization tank 2
When the waste liquid is circulated from below to above, among the chilled stones loaded in the acid neutralization tank 2, the chilled stones below are depleted faster by the neutralization reaction than the chilled stones above, so that Meanwhile, the particle size of the fluorite at the lower portion becomes smaller, while the particle size of the fluorite at the upper portion does not become so small, so that the internal space of the acid neutralization tank 2 does not clog.
【００１９】酸中和槽２内を流通させる廃液の流通速度

通速度で廃液を流通させると中和が完全に達成される。
換言すると、流通速度が大き過ぎると中和が完全に行わ
れないことがあり、流通速度が小さいと中和処理効率が
悪くて工業的ではないことがある。The flow rate of the waste liquid flowing in the acid neutralization tank 2 is usually 5 to 15 cm / min. When the waste liquid is caused to flow at such a flow rate, the neutralization is completely achieved.
In other words, if the flow rate is too high, the neutralization may not be completely performed, and if the flow rate is low, the neutralization efficiency may be poor and not industrial.

液のみが飽和状態となって、酸性廃液全体の中和反応が
低下する。一方、流入速度を早め過ぎると、寒水石７と
透析廃液の接触時間が短くなり、中和が不充分となる。In other words, the flow rate of the dialysis waste liquid into the acid neutralization tank 2 needs to be at least a certain fixed rate. When the inflow speed is substantially 0, only a part of the acidic waste liquid on the surface of the spar 7 becomes saturated, and the neutralization reaction of the entire acidic waste liquid is reduced. On the other hand, if the inflow speed is too fast, the contact time between the chilled stone 7 and the dialysis waste liquid will be short, and the neutralization will be insufficient.

流入速度となる。尚、図１の装置においても水道管１３

度を大きくすることは可能である。In the example shown in FIG. 1, the flow rate of the dialysis waste liquid into the storage tank 3 becomes the flow rate of the dialysis waste liquid into the acid neutralization tank 2 as it is. Incidentally, the water pipe 13 in the apparatus of FIG.
, It is possible to increase the flow rate of the dialysis waste liquid into the acid neutralization tank 2.

In consideration of the frequency of replenishment of cold water stones, the height of the acid neutralization tank 2 is desirably 40 cm or more, preferably 60 to 100 cm.

If the outflow of the chilled water can be prevented and the waste liquid flows smoothly, a fine filter or the like may be used instead of the net. In short, the supporting member which can flow the waste liquid and hold the natural rock particles such as the dolomite, which is an example of the lower net 5, is the acid neutralization tank 2.
It is sufficient if it is provided in the opening below.
