Due to the Basel Agreement established at the Global Environment Summit in July 2012, ocean dumping will be banned worldwide. Therefore, the method of treating human livestock excrement and the disposal of the final sediment of the treatment plant has become impossible with the conventional method, and this problem has been actively taken up in various fields. In addition, although there is a plan to reuse sludge from human livestock and the final sediment of the treatment plant, there is a risk of odor pollution and insect damage such as flies, and the current situation is that it is difficult to deal with it. Therefore, an object of the present invention is to provide an effective use method of human feces sludge and final sediment of a treatment plant.

It is made by paying attention, and in a wastewater treatment method of adsorbing and treating wastewater using an adsorbent, a charcoal of sludge is used as the adsorbent. The sludge charcoal is preferably obtained from human feces sludge and / or the final sediment of the treatment plant. In addition, it is preferable that the sludge charcoal-containing material be mixed with clay so as to be precipitated in water.

い。The sludge carbonization is carried out by removing foreign matters from sludge such as human livestock manure sludge and final sludge of the treatment plant, mixing clay with the sludge, and performing pretreatment such as water content adjustment, molding and drying. The details of the manufacturing method will be described below. First, the mixed foreign matter is removed from sludge such as human animal feces sludge and final sludge of the treatment plant. In this way, a deodorant such as wood vinegar is added to the sludge from which foreign substances have been removed, and the mixture is stirred to deodorize the peculiar odor of these sludges. Next, clay is mixed in the sludge in order to precipitate the finally obtained carbide in water. The amount of clay mixed in this sludge varies depending on the usage situation and purpose of use,
Generally, about 20 to 50% by weight of sludge is preferable.

It is preferable to set the content to about% by weight. Next, the sludge whose water content has been adjusted in this way is molded using an extruder or the like. The size to be molded varies depending on the intended use and range of use, but generally the smaller the mass and the larger the surface area, the more effectively the toxic substances are adsorbed during the treatment of sewage.

The same amount of activated carbon was deposited in each sewage tank, and the sewage treatment capacity was compared. Since the activated carbon made from coconut has a low specific gravity by itself, it was put in a net of 10 mm mesh and sunk with a weight. Since the sludge charcoal had clay added, there was no problem as it naturally precipitated. Regarding the results of the sewage treatment, the adsorption amounts were almost the same in both cases.

を行える。As described above, according to the sewage treatment method of the present invention, it is possible to perform the sewage treatment while effectively utilizing the human animal dung sludge and the final sediment of the treatment plant, which have been conventionally troubled with the waste treatment. In this case, the bacteria contained in the sludge charcoal are decomposed by the minerals contained in the sludge charcoal to promote biological wastewater treatment. In addition, when clay is mixed with the sludge charcoal, unlike the activated carbon, neither a net for storing nor a weight for precipitating the sludge is required, and the wastewater treatment can be performed only by adding the sludge charcoal.
