When purifying sewage of 8.640 m 3 / day and BOD of 15 mg / liter, the total BOD load L of the purifier is 86.
40 x 15 g = 129.6 kg / day. On the other hand, when this is treated using a purification unit in which three double box culverts (see FIG. 2) having a length of 1.5 m, a width of 1.5 m, and a depth of 1.5 m are connected and a contact oxidizing material is loaded therein. , The content of one box culvert is 1.5 × 1.5 ×

On the other hand, if the volume load a of the BOD per 1 m 3 of the contact oxidizing agent loaded in the box culvert is obtained from experimental results and the like, the BOD volume load x per purification unit can be calculated. Now, assuming that the volume load x of BOD per 1 m 3 of the contact oxidizing material is 0.3 kg / m 3 day, the volume load X of BOD per purification unit is 0.3 kg / m 3 day × 18.26. $ 5.48 kg / day.
