物の他に担体を設置しておくことが望ましい。In the present invention, bacterial cells comprehensively identified using PVA are placed in the purification section of the device, and the immobilized microorganisms are used to purify them until a biofilm is formed on the surface of the carrier in the purification section to the extent that sufficient purification can be achieved. . Since surplus sludge is generated during the sewage treatment process, the sludge is adsorbed and filtered by the carrier, and the biofilm formed on the carrier improves the purification ability of this device. Therefore, it is desirable to install a carrier in addition to the immobilized microorganisms in the purification section.
ＰＶＡにより固定化する微生物としては目的の汚水を浄
化処理できる全酸化処理の活性汚泥を用いることが望ま
しい。As the microorganisms to be immobilized by PVA, it is preferable to use activated sludge that has undergone total oxidation treatment and can purify the target wastewater.

- Using the boric acid method. This PVA-freezing method involves mixing fully oxidized activated sludge and an aqueous PVA solution, and then
This method involves freezing at 0 to -80'C for 24 hours. Also,
The PVA-boric acid method uses fully oxidized activated sludge and PVA.
This is a method of mixing an aqueous solution of , dropping this into a boric acid solution, and stirring it overnight to form a gel.

けても良い。Regarding the method of attaching microorganisms immobilized by PVA to the device, there is a method of making them into spheres or cubes and mixing them with the carrier in the purification section, but if the microorganisms immobilized by PVA do not come out, Place it in a case with holes drilled all over the top and bottom, and place it in a place where the flow path of the device flows from the bottom to the top.
It is desirable to install the system so that the immobilized microorganisms are agitated by the flow, since this increases the contact area with the wastewater. Further, it may be attached separately without being mixed with the carrier of the purification section.
以上の方法は、該装置の使用当初や使用途中における浄

介して浴槽１に供給される。The bath water 2 contained in the bathtub 1 is supplied to the filter part 5 via the first water pipe 4 by the bomb 3, and impurities are filtered out. Next, the first purification section 6 is removed from the bath water filter section 5.
is supplied from below. Although not shown in the figure, this first purification section is filled with furnace material (crisbar), and above it is provided microorganisms 7 immobilized with PVA. This microorganism is immobilized to a size of about 5 to 6 mm, and is housed in a case 8 having a through hole that prevents the microorganism from flowing out. If the amount of microorganisms is about the same as the volume of the case, contact with running water is preferable from the viewpoint of purifying action. The bath water is then supplied to the second purification section 9. This purification section is filled with maifan stone (not shown in the figure), and like Crisbar, microorganisms are gradually formed during use and purify the bath water. The purified bath water is then adjusted to a predetermined temperature by the heater 10 and supplied to the bathtub 1 via the second water pipe 11.

00g was filled. The amount of bath water was approximately 2,000 ml, and the temperature was adjusted to approximately 41'C using a heater. Further, the circulation flow rate was set to 20 17 min. Bebuton 3g.
The turbidity of the bath water after adding 1 g of glucose and 0.5 g of dipotassium hydrogen phosphate was measured. The turbidity was measured by an integrating sphere photoelectric method, and the COD was measured by an acid method. The results are shown in Table 1. As a comparative example, a similar test was conducted without filling with PVA-immobilized microorganisms. These results show that the turbidity in bath water is faster and smaller when filled with PVA-immobilized bacterial cells.
This shows that the bath water purification speed is fast. Although the bath apparatus that circulates bath water has been described above, the present invention is also applicable to purification of circulating water in pools, fountains, and the like.
