酸素を供給し水質を改善する。The sludge mainly consists of anaerobic bacteria and generates ammonia, methane, hydrogen sulfide and the like, and pollutes water. The CaCO 3 component contained in the biozoa generates some oxygen in the water, and particularly has a high water quality. It is thought that Ca (PO 4 ) reacts with the phosphorus compound which is one of the nutrient causes, so that phosphorus is drastically reduced, and active oxygen generated as shown in Chemical Formula 1 in the reaction process has a sterilizing effect. By treating various bacteria, suspended matter supplies oxygen to lakes and rivers in a dilute oxygen state to improve water quality.

ｐｈを中性化して沈降固定化し水質を浄化する。[0011] The bryozoa is in an intermediate state of mineralization in water and calcites by the action of calcium carbonate, and physically adsorbs heavy metals, cutting oil, ink, sulfur dioxide, etc. contained in sludge into the microporous structure. Then, the water quality ph is neutralized and settled and fixed to purify the water quality.

5 to 27.0 mg / g Mercury adsorption amount 20.0 to 24.
0 mg / g), which is not a mere ion-exchange effect but is immobilized as an insoluble substance to maintain stable properties and once immobilized, the incorporated heavy metals dissolve.
Since it does not decompose, no burden is placed on the disposal facility.

となる。Most of the causes of water pollution in rivers and lakes are those whose water quality is eutrophic by organic substances, which itself is a substance of high nutritional value, and these pollutants are flocculated to cause flocculation and sedimentation. The precipitate becomes a particularly useful precipitate.

However, the fossil of this fresh moss is a bryozoa itself, which is completely different from general shell fossils.A major feature of bryozoa is that it can be easily peeled off with a finger, making powder processing simple.

Since h is alkaline, the water quality is also inclined in the alkaline direction, and the effect of suppressing spawning of mosquitoes and the like is also recognized. In natural lakes and marshes,
It is also recognized that the effect of maintaining the water quality is exhibited only by precipitating the briozoa.

い事が確認されている。[0017] Since the bryozoa is naturally occurring and is harmless to the natural world, it does not affect the natural world even if it is discharged in the course of turbid water treatment, and is easy to handle. By only providing the adjusting device for the charged amount and the stirring device, the treated water can be produced sufficiently within the drainage regulation value. Analysis of the Hokkaido Prefectural Central Agricultural Experiment Station confirmed that mercury, arsenic, cadmium, and lead were not detected.

The processing procedure is as follows: mining by open pit mining, 100 ° C. in a drying furnace. With moisture adjustment,
The drying temperature at this time is about 1 unit, which is the basic unit of biozoa.

Table 3 shows the results of the analysis at the Rikkyo Industrial Testing Center.

び図３による比較で明らかである。Further, by mixing an inorganic neutral coagulant containing a composite alumina silicate of a natural mineral as a main component with the fossil brizozoa powder, a necessary effect is obtained due to a synergistic effect of an ion exchange effect and a physical adsorption effect by a microporous structure. It suppresses the agitation force and hasten the flocculation of the underwater contaminants, thereby exhibiting the effect of the flocculant in a shorter time. This is apparent from the comparison according to FIGS. 1, 2 and 3.

For example, when a flocculant formed by microflocs is mixed with a flocculant forming a microfloc, a microfloc can be taken into the microporous structure of the biosorber, and a floc having a larger specific gravity can be formed.

The coagulant according to claim 1 or 2 is sprayed on the water surface in an appropriate amount in accordance with the state of a lake or the like to be purified, and is suspended on the water surface. The sediment is forcibly settled, but at this time, it takes in pollutants in the water to form flocs and settles on the bottom of the lake. In places where there is a water flow such as an inlet to a river or sedimentation basin,
Storing the flocculant according to claim 1 or 2 in a suitable container,
At the inlet, a device that can adjust the amount of water to be supplied according to the amount of flowing water is attached, and finally, a stirring device with flowing water is attached. FIG. 4 shows the concept of the apparatus. In any case, unlike the sludge, the size of the precipitate becomes a solid state of about 0.5 mm to 2.0 mm, and the handling of the dredging process is facilitated.

The results are shown in Table 4 for the sedimentation of turbid water.
Table 5 shows the turbidity water concentration and the amount added, and Table 6 shows the PAC comparison experiment. Thus, the product of the present invention using foliar biospores has a cohesive property against changes in the SS concentration and properties of the influent water. With little change, the cohesiveness of the conventional PAC is impaired due to the change in the influent water and the success or failure of pH adjustment. From this, the product of the present invention can hardly be required to manage a water purification device, and can exhibit its effectiveness particularly in a place where use in natural flowing water is required.

Add 800 g of red clay into 20 l of water. After vigorous stirring for 1 minute, let stand for 10 minutes. After standing, the supernatant water is collected and used as turbid water. A predetermined amount of turbid water is collected with stirring immediately before the experiment. Table 7 shows the pH, SS, and absorbance of the turbid water after the experiment.

In addition, it is harmless even if it is washed away from reservoirs, etc., because it is naturally returned in the end, so it can be used easily by anyone without the need for special technology. The required equipment is small-scale, which has economic efficiency and safety effects.
