The outline of the activated sludge method is shown below. FIG. 1 shows a flow chart of a typical activated sludge method. As shown in FIG.
Sewage containing organic matter is first passed through a screen to remove large foreign matter such as dust. Next, fine sand and the like are removed in the sand basin and flow into the first sedimentation basin 1. First
In the sedimentation basin 1, sewage is ventilated. As a result, microorganisms start to propagate and flocs float. This is called activated sludge and is mainly composed of bacteria and protozoa.

Here, by being mixed with the organic matter-containing water and passing air e,
Organic matter in the organic matter-containing water is oxidized by microorganisms. Some of the oxidized organic matter is taken up by microorganisms, absorbed by flocs, and reduced in concentration. Next, the activated sludge mixture discharged from the aeration tank 2 is sent to the second sedimentation basin 3, where it is separated into supernatant water and sludge. The supernatant water becomes treated water,
The sludge is returned to the aeration tank 1 as returned sludge a. By continuously performing this operation, the organic matter in the wastewater is purified.

完成した。However, in such a conventional method for treating water containing organic matter, the organic matter is taken up by the microorganisms in the activated sludge and the excess sludge is added as the microorganisms increase. b occurs. Therefore, sludge treatment of the excess sludge b is required, and there are the following problems. That is, the organic matter-containing water is discarded in the sludge treatment plant 4 through solid-liquid separation → concentration → dehydration → drying → incineration → cement solidification, etc. Around that time, there was an odor problem.
Thereby, the inventor studied a method of treating the organic substance-containing water. As a result, water containing organic matter contains "cement-based solidifying material and quicklime" and "activated carbon or zeolite."
And "fluidized bed boiler ash" were added directly, and it was found that the organic matter was precipitated and solidified at the same time as the deodorization of water, and the odor of the precipitate was hardly found. Thus, the present invention was completed.

However, when the amount of organic matter is large and it is difficult to solidify, the ratio of the solidified material may be increased. In order to further enhance the deodorizing and organic substance adsorption effects, the ratio of the adsorbent may be increased.

The addition amount of the deodorizing material as a whole made of lime and quicklime is 32 to 4% by weight based on the water containing organic substances.
And With this composition, even if the organic matter is relatively large as compared with the simple substance, it can be appropriately solidified. In any case, if the amount of each material on the solidified material side with respect to the organic substance-containing water is small, sufficient solidification of the precipitate cannot be achieved.
Conversely, a large amount of this addition is uneconomical.

It can be appropriately determined according to the odor intensity and the organic substance content of the organic substance-containing water to be treated. However, activated carbon alone is 15% by weight or less, especially 10 to 10% by weight, based on water containing organic matter.
It is preferable to add 0.2% by weight, and in the case of zeolite alone, it is preferable to add 15% by weight, particularly preferably 10 to 0.2% by weight. Further, in the case of a fluidized bed boiler ash alone, it is preferable to add 75% by weight or less, particularly 50 to 1% by weight.

In particular, the content of the fluidized-bed boiler ash is set to 55% by weight or less, particularly 40 to 1% by weight, and the total amount of activated carbon, zeolite, and fluidized-bed boiler ash on the adsorbent side is set to 5 to 0.1% by weight. The content is set to 50 to 1% by weight based on the organic substance-containing water. By this blending, it is possible to sufficiently deodorize and precipitate organic substances. In any case, if the amount of each material on the adsorbent side relative to the organic substance-containing water is small, the deodorization of the organic substance-containing water and the precipitation of the organic substances are insufficient. Conversely, a large amount of this addition is uneconomical.

Further, the fluidized-bed boiler ash contains a large amount of unburned carbon, and thus is effective for deodorizing organic-containing water and removing organic substances by absorbing malodorous substances and organic substances. In addition,
Since fluidized-bed boiler ash is generated as industrial waste,

For example, even if they are added simultaneously, any of them may be added first. As described above, the addition ratio of each additive is preferably appropriately determined in the above range according to the content of the organic substance and the degree of the odor. According to the method of the present invention, by simply adding these additives to the organic substance-containing water, the malodorous substances and the organic substances are adsorbed and naturally precipitated and solidified, so that the organic substance-containing water can be treated efficiently.
