Te, pellets made from the rear predicates of bottom mud is used, in this
Ri bottom mud can be effective use of, yet such sediment pellets you excellent cleaning ability. The bottom mud pellets have a structure in which the dried bottom mud is baked to be porous, and purification microorganisms are fixed. When the bottom mud is baked, the plant fibers contained in the bottom mud are carbonized, and the carbon surface is exposed on the porous inner wall. And, since the purifying microorganisms are fixed in the pores, when treated water flows into the pores, the contaminants in the treated water are adsorbed on the carbon surface and decomposed and purified by the purifying microorganisms. . Furthermore, since the present pellets are porous, they have a large adsorption area and can fix a large amount of purification microorganisms. Further, the inside of the pores is an optimum environment for the purification microorganism. Therefore, it is possible to top toward the adsorption performance and cleaning performance of the contaminants.

で、底泥は多孔質状となる。Since the bottom mud pellets float in water, there is no particular problem even if a relatively large amount is stored in a floating container. Since such bottom mud pellets can take oil such as crude oil floating on the water surface into the pores, they can also be used as an oil adsorbent. Further, by fixing the oil-purifying microorganisms in the pores, they can be used as an oil-decomposing material.
During the drying and firing of the bottom mud, the bottom mud can be made porous by introducing air into the bottom mud and forcibly stirring it. The bottom mud contains vegetable fibers, which are carbonized in the process of firing, so that the bottom mud becomes porous.

含水率の底泥を得た。In the lower container 3, a bottom mud pellet in which the dried bottom mud is baked to be porous and the purification microorganism is fixed is stored. Since the bottom mud pellets are dispersed and stored in a plurality of rooms of the lower container 3, it is possible to prevent the bottom mud pellets from shifting. This bottom mud pellet is produced by the following method. As bottom mud, riverbed, pond,
Use mud from lakes and lakes collected by dredging vessels. The collected bottom mud having a water content of about 95% is dehydrated to a water content of about 50% by a forced dewatering machine. Then, the bottom mud naturally dried in the previous step (having a water content of about 20%) is pulverized, and the dewatered bottom mud (having a water content of about 50%) is obtained.
Mix. The mixing ratio was 6: 4, which was forcedly dewatered bottom mud: naturally dried bottom mud. Thus, bottom mud having a water content of about 28 to 30% was obtained.

た。Next, the bottom mud is pulverized by a roller pulverizer and mixed to form a clay. This is extruded with an air pump, and high-speed stirring is performed with a stirrer while pressurizing bubbles in the clay. During high-speed stirring, a flocculant and a deodorant (microorganism) for deodorizing the bottom mud are introduced into the bottom mud, and after the malodor is completely removed, the bottom mud is sent to a pellet forming machine. The pellets thus completed are fired in a rotary kiln (rotary kiln). The temperature at this time is 400 ~
The temperature was set to 600 ° C. and the second time was set to 700 to 1000 ° C. When manufacturing an oil adsorbent, the second temperature is set to 15
Set to 00 ° C. Thus, the organic fibers inside the bottom mud are carbonized in the first firing step, and the whole becomes porous in the second firing step. In addition, the size of the pellet was set to a size that can be accommodated in the divided room of the lower container 3.

頻度を少なくすることも可能となる。Next, the operation of this embodiment will be described. When the floating container 1 of the present embodiment is poured into water, the upper container 2 is above the water surface, and the lower container 3 is immersed in water. lake,
There is a water flow in a swamp, a river, and the like. Water flows into the lower container from the opening of the net forming the lower container 3, and contacts with the bottom mud pellets to purify the water quality. Spilled out of container. By circulating the water in the container 3 as described above, the water is continuously purified, and the purification ability can be improved. The fin 4 swings the upper container 2 in response to wind resistance, whereby such water circulation can be forcibly performed. This is effective when purifying water when the water flow is small. The floating container 1 can float on the water surface, and the upper container 2 and the lower container 3 can easily exchange and collect the bottom mud pellets in the lower container 3 by detaching an engaging mechanism (not shown). Can be.
In addition, since the floating container 1 does not settle on the bottom of the water,
It is also possible to prevent clogging of the holes in the net of the lower container 3 and reduce the frequency of maintenance.
