FIG. 1 shows an embodiment in which the rainwater purifying apparatus of the present invention is applied to a domestic rainwater storage tank. The rainwater purification device 1 is arranged between the forced circulation flow paths 3 a and 3 b of the rainwater storage tank 2. Dirty water containing organic substances and general bacteria accumulated in the rainwater storage tank 2 flows from the inflow port 4 to the water flow path (outward path).
A water purification module 7 consisting of a basic mineral substance 6 to which a microorganism decomposing an organic substance is attached by a pump 5 via 3a. In this water purification module 7, four or more kinds of microorganisms such as protein-degrading bacteria, deaminating bacteria, ammonia-oxidizing bacteria, and nitrite-oxidizing bacteria are propagated. The dissolved organic matter in the dirty water in the water purification module 7 is decomposed into amino acids by proteolytic bacteria and deaminative bacteria adhering to the surface of the mineral 6 as shown in FIG. Will be immediately decomposed into. This ammonia is also oxidized and decomposed into nitric acid by ammonia-oxidizing bacteria and nitrite-oxidizing bacteria adhering to the surface of the mineral substance 6. On the other hand, an ejector 8 which is an air supply means is installed at the inlet of the water purification module 7, and oxygen in the air is sucked by the ejector effect through the flow pipe 9 to generate bubbles containing oxygen. Ammonia formed by the decomposition of suspended organic matter formed from bird excrement or tree leaves by this oxygen is accelerated by the bacteria to be oxidized and decomposed, and is completely converted to nitric acid according to the following formula.

The mineral substance 6 of the present invention has a tow-shaped cross section as shown in FIG. 4 and is curved in an arc shape as shown in FIG. Therefore, there is no occurrence of a portion where the mineral matter 6 overlaps and does not come into contact with water, the contact area with water in the water purification module is widened, and the area in which water purification microorganisms can be cultured can be maximized.

どが主成分である。FIG. 5 is a perspective view of the above-mentioned mineral substance 6, and even when viewed from this shape, the water flows in the water flow direction regardless of which direction the water hits. Therefore, the resistance of the mineral matter 6 in the water purification module is extremely small. The individual mineral substances 6 contained in the water purification module 7 were produced by granulating blast furnace. This granulated blast furnace is produced by rapidly cooling slag generated in a blast furnace of an iron mill at a rate of 0.5 ton per ton of molten iron, and is mainly used as a raw material for cement and a soil improving material. The blast furnace water frame is fired into a porous vitreous material and contains CaO, SiO 2 , Al 2 O 3 , MgO and the like as main components as shown in the table below.

Since it can be neutralized with CaO, the pH of the portion to which the water-purifying microorganisms are attached can be kept at about 8, so that the activity of the water-purifying microorganisms can be improved. Figure 9 shows NH in water
It shows the relationship between the activity of microorganisms decomposing 4 + and NO 2 − and the pH of water, and any microorganism shows a high activity at pH 7 or higher.

On the other hand, since the microorganisms that are negatively charged tend to adhere to the mineral substance 6 for purifying water, the mineral substance 6 is most suitable as a fixed bed of the microorganism.

Silicate glass, borosilicate low alkali glass, phosphate glass),
It is a waterproof type whose irradiation part is made of fluororesin. This irradiation part is preferably quartz or quartz with a fluororesin coated on the running water channel side. This is because quartz and fluororesin are particularly excellent in transmitting ultraviolet light, and even if quartz is cracked, if the quartz is coated with fluororesin, there is no concern that the broken quartz pieces will enter the water. On the other hand, the optimum product of the time for rainwater to pass through the ultraviolet ray lamp 10 in one pass and the ultraviolet ray irradiance of the ultraviolet ray lamp 10 is 10 to 10 5 μwsec / cm 2 Vertical is better than fat. This UV irradiance is 1 at a position 1 m away from the UV lamp light source.

The water purification module 7 is a cylindrical one made of vinyl chloride resin having an internal volume of 6 liters, and inside it is a microorganism that decomposes organic matter from a ceramic that is made of blast furnace water granulation and has a tow-shaped cross section and is curved in an arc. Used for the fixed bed of. Further, an ejector 8 was installed at the inlet of the water purification module 7, and 1 l / min of air was supplied by the ejector effect. The amount of oxygen in the air is more than the amount required for the organic substance-degrading microorganisms adhering to the mineral substances of the water purification module 7 to oxidatively decompose the organic matter, and therefore the amount of water passing through the water purification module 7 is increased. The amount of dissolved oxygen is saturated. In addition, the ultraviolet lamp 10 disposed downstream of the water purification module 7 described above.

にすることができる。As described above, according to the rainwater purifying apparatus of the present invention, the following effects can be obtained. (1) Since a ceramic containing a basic substance as a main component is used in the fixed bed of microorganisms in a water purification module that decomposes organic matter in rainwater storage tanks by utilizing microorganisms, acid is generated by decomposing organic matter. However, since the PH does not decrease around the fixed bed to which the microorganisms adhere, the high activity of the microorganisms can be maintained. (2) Organic matter in acid rain with a low pH could not be decomposed by microorganisms in the past, but the rainwater purification apparatus of the present invention can decompose organic matter in acid rain with a low PH. (3) Further, in the present invention, since the ejector which is an air supply means is installed at the inlet of the water purification module to blow in the air, the microorganisms of the water purification module efficiently use the oxygen in the air to efficiently remove organic substances in rainwater. Disassembles well. (4) The basic mineral substance, which is the fixed bed of the water-purifying microorganisms of the present invention, does not overlap because the cross-section is curved toy and has an arcuate shape, and the contact area with water in the purification module is the most. Can be widened. Furthermore, since the flow of water flows in the direction of water flow regardless of the surface of the mineral matter, the resistance of the mineral matter is extremely small. Therefore, the output of the pump for forced circulation can be small, and a water purification device with low power consumption can be obtained. Furthermore, since the end portions of the individual minerals are stacked in contact with each other, variations in the resistance value of the water flow due to the partial portions are small, and the water flow in the water purification module is made uniform. Therefore, the microorganisms can be uniformly replenished in a wide area in the water purification module, so that an efficient water purification apparatus can be obtained. (5) The ultraviolet lamp used in the water purification device of the present invention is
Without adding any chemical substances to the target, it can perform transient and effective sterilization in a very short time, so it does not harm humans and humans that decompose organic substances in water like conventional ozone. Can sterilize unwanted bacteria in rainwater. (6) Water supply and demand is becoming tight in urban areas, but rainwater use can be a very realistic water resource measure.
