理方法は、脱水して焼却してしまうのが一般的である。However, the conventional carbon-made filter material has a drawback that it is expensive. By the way, at the present time, the paper mill has a problem in processing the paper sludge generated in the paper manufacturing process. This is because if the paper sludge is poured into the river as it is, it will accumulate as sludge, which will lead to pollution of the river and the ocean. Therefore, the current method for treating paper sludge is generally to dehydrate and incinerate.

And a calcium chloride mixed solution or potassium permanganate, or a mixture of carbonic acid potassium permanganate and a mixed solution of cobalt chloride, etc., and a clay that is baked and hardened at a temperature lower than the temperature at which carbon burns,

The present invention provides a filter material obtained by baking the kneaded product at a temperature at which carbon does not burn.

ボンが優れた濾過能力を発揮する。When the kneaded product of the paper sludge, the clay and the carbonization aid is fired, the paper sludge is carbonized to become carbon. At this time, carbonization of the paper sludge is promoted by the function of the carbonization auxiliary material. Since the clay is baked at a temperature lower than the temperature at which the carbon burns, the carbon remains in the state of being mixed with the clay without burning. This carbon exhibits excellent filtering ability.

The paper sludge used as the raw material is a large amount contained in the wastewater of the paper mill, and this is subjected to a centrifuge or a filter press to obtain a water content of about 30 to 50%. The carbonization aid is a mixed solution of phosphoric acid (H 3 PO 4 ) and calcium chloride (CaCl 2 ), potassium permanganate (KMnO 4 ), or a mixed solution of potassium permanganate and cobalt chloride (CaCl 2 6H 2 O). And so on. By properly using these carbonization aids, a filter medium suitable for the application can be obtained. This point will be described later. As the clay, one that can be fired at a temperature at which carbon does not burn, that is, at a temperature of about 450 to 470 ° C. is used. For example, high-quality elutriated clay is applicable.

り、濾過能力が飛躍的に高まる。The filter material of the present invention has the following excellent effects. It contributes to pollution prevention because it uses paper sludge, which has been a problem for disposal, as a raw material. Paper sludge is essentially a waste material, so it costs almost no raw material,
In addition, the carbonaceous filter material can be provided at a very low price because it can be manufactured by a simple manufacturing method in which the carbonization auxiliary material and clay are kneaded and fired. In a filter material coated with a chemical such as manganese zeolite or manganese sand, the chemical is exfoliated by long-term use or backwashing, which causes a problem of deterioration of filtration ability. Even if the surface is worn, the filtration performance does not decrease because carbon is mixed up to the point. Since clay is used as a shaping material, the filtering material can be processed into any shape. Therefore, the present invention can be applied to various fields, for example, by forming a cylindrical shape as shown in FIG. 2 through which exhaust gas is passed and adsorbing harmful substances in the exhaust gas.
It is harder than a 100% carbon filter medium because the whole shape is maintained by the clay that has been baked and solidified. Therefore,
Rapid contact filtration is possible. Even if impurities etc. adhere to the filter medium, it can be easily regenerated by baking the surface. Since the shrinkage rate of clay and paper sludge during firing is different, countless fine holes are formed inside the filter medium. The fine pores increase the surface area of the filter material, which dramatically increases the filtering ability.
