とを発明した。First, the present inventor conducted various studies on the production of a porous sintered adsorbent for sewage sludge that can efficiently adsorb and treat humic substances mixed in wastewater. Sewage sludge incineration ash obtained by incinerating sewage sludge and organic matter having a thickening effect are well γ-combined and granulated to a diameter of about 0.5 to 10 m by the binder effect of the organic matter.

の間を循環させた。Next, as to how effective the porous sintered adsorbent produced in this way is in the adsorption treatment of humic substances, as shown in the following experimental example, activated carbon used as an adsorbent for humic substances and -C As a result of the comparison, we reached the conclusion shown in the experimental example. As mentioned above, a porous sintered adsorbent produced by mixing sewage treatment sludge incineration ash and organic matter, granulating it, and then sintering it;
The activated carbon was separately sieved through the 1mth and 2nd round sieves, and the materials that passed through the 2nd round sieve and remained on the lrmth sieve were placed separately in transparent cylinders of the experimental apparatus, each having the same volume. A humic acid solution adjusted to 24 μ/l was circulated between the cylinder and the Erlenmeyer flask at a rate of 36 μ/min via a metering pump.

が判明した。As mentioned above, when we measured the weight of the same volume of porous sintered adsorbent and activated carbon filled in a transparent cylinder, the weight of the porous sintered adsorbent was 342g, while the weight of activated carbon was 178g. It was found that the sintered adsorbent has a higher density than the activated carbon.

断されている。As is clear from the graph in Figure 1, the adsorption rate of humic acid when filled with the porous sintered adsorbent of the present invention is slightly slower than that of activated carbon, but the adsorption pattern is almost the same as that of activated carbon. It is clear that The present inventor has discovered two cases in which the above-mentioned sewage treatment sludge incineration ash is used as a granular porous sintered adsorbent with many pores, and a case where the sewage treatment sludge incineration ash is simply used without using this granular porous sintered adsorbent. A comparison was made between the use of molten slag produced by melting incinerated ash at 1,000 to 1,300°C, and it was found that molten slag is also effective in adsorbing humic substances, but the porous incineration of the present invention It became clear that the effect was incomparably smaller than that of condensed adsorbents. The reason for this is that the porous sintered adsorbent used in the present invention has a porous interior with many pores.
It is considered that the purpose of this is to increase the area where the adsorbent contacts wastewater and the like and the area where it adsorbs soluble components such as humic substances.

果が得られた。The present inventor used the experimental apparatus used in the above experimental example to
When experiments were conducted on the porous sintered adsorbent of the present invention and activated carbon using ligninsulfonate phosphorus instead of humic acid, the effect was slightly less than that of humic acid in the above experimental example, but it still showed a considerable effect. It was also found that decolorization of dyeing wastewater discharged from a dyeing factory using the porous sintered adsorbent according to the present invention was similarly attempted, and the results showed that the decolorization of dyeing wastewater discharged from a dyeing factory was approximately It was found that a decolorization efficiency of 60% could be obtained. The porous sintered adsorbent of the present invention, which has been adsorbed with humic acid 1, lignin sulfonic acid, dye, etc. until it becomes saturated after long-term use,
It has also become clear that repeated use is possible by heat treatment at ~800°C. Next, the present inventor compared the manufacturing cost of conventionally commonly used activated carbon with the manufacturing cost of the above-mentioned porous sintered adsorbent according to the present invention, and found that the manufacturing cost of activated carbon is approximately 950 yen. On the other hand, the cost of the adsorbent is about 40 to 95 yen, and it has become clear that activated carbon can be manufactured at a manufacturing cost that is 1/10 to 20 times lower than that of the adsorbent. Although the above embodiment describes the treatment of wastewater, very good effects were obtained by treating clean water in a similar manner.
