2. Description of the Related Art As a method for solid-liquid separation of wastewater as described above, precipitation separation, flotation separation, centrifugal separation, filtration, drying and the like are generally known. Among these methods, there are a method of utilizing gravity, a method of using pressure and centrifugal force, and the like. In many cases, a drug is used in combination except for a part of gravity filtration. The present invention relates to a gravity filtration method. Sand, sawdust, and the like are conventionally used as a filtering material (filter material), and sewage is poured into a filtration tank in which 30 to 100 cm is deposited, and sewage is discharged near a deposition surface. The solid matter inside is trapped, and the solid matter is removed manually after drying in the sun to restore the filtration ability.

Therefore, the restoration of the filtration capacity differs depending on the solar drying period, that is, the drying capacity varies depending on the season and region (in winter, about 1/3 to 1/5 of that in summer).
) And its drying ability is extremely low compared to other drying methods (water-evaporating capacity per square meter of filter bed in winter is about 1.5 to 2.0 kg per day). There is a problem that the tank facility scale becomes large. Also,
The pores in the filter tank are blocked by solids of a small particle size that are not filtered on the surface of the filter tank and microorganisms that grow in the filter tank, and the filtering capacity gradually decreases. There is a problem that it has to be replaced.
As described above, in the conventional gravity filtration method using a filter medium such as sand and sawdust, the filtration efficiency is reduced due to the clogging of the solid material retained by filtration on the surface and inside of the filter medium, thereby reducing the size of the treatment facility. There are limits.

If the treatment with the filter medium 2 is continued, the retained solids block the space of the filter medium 2 and cause clogging, which causes a decrease in filtration capacity. Stirring / turning is performed by moving the stirring / turning blade up and down randomly along the length direction of the back and forth, and randomly in the width direction. 2 The air from the blower 7 is forcibly ventilated from the lower gap of the lowermost net 5 through the porous tube 8 to supply oxygen (air) to the filter medium 2 to promote aerobic fermentation. By this operation, the easily decomposable substance in the solid material causing the clogging of the filter medium 2 is decomposed and generates heat, the water in the material is evaporated, and the dry matter (solid matter) due to the decomposition of the solid matter Due to the decrease, the clogging phenomenon is eliminated, and the filtration ability is restored.

The dimensions of the filter medium 2 used here are as follows:
Extremely fine ones are easily clogged, and extremely large ones cannot be filtered. Therefore, the filter material 2 has a size of about 0.1 mm (minimum dimension of sawdust) to about 5.0 mm (maximum dimension of rice husk). Deposition height is 0.5 in practical terms
The filter medium 2 is compacted and deposited as much as possible, and the space of the filter medium 2 is reduced so that fine solids in wastewater can be filtered. Therefore, in the filtration tank 1 using the filter medium 2 and the like, it is possible to increase the amount of sewage that can be treated by the filter medium 2 of a fixed volume, and to improve the treatment efficiency.
Processing time can be reduced, processing facilities can be reduced, and the like.

First, sewage discharged from a livestock house such as a piggery is pumped up by a pump P in an amount to be treated every day, and is uniformly sprayed from a sewage spray pipe 3 onto a filter medium 2 deposited in a filtration tank 1. Most of the solid matter in the sprinkled sewage is filtered and held in the upper layer of the filter medium 2, and the filtrate having a reduced solid matter content is discharged from the mesh 5 at the bottom of the filtration tank 1 and passes through rice husks, boring stones 6 and the like. The water is discharged from the drain groove 9 to the water seal portion 10. The filtrate overflowing from the water sealing section 10 is temporarily stored in a filtrate storage tank 11 and discharged through a discharge pipe 12.

The solid matter held in the upper layer of the filter medium 2 is stirred and mixed by moving the stirring and turning mechanism 4 back and forth, right and left, and moving the stirring and turning blade up and down to stir and mix the filter medium 2, and the solid material below the mesh body 5. The air from the blower 7 is forcibly ventilated from the gap through the perforated pipe 8 to supply oxygen (air) to the filter medium 2 to perform aerobic fermentation to prevent a decrease in the filtration capacity and maintain the filtration capacity. If the filtration ability is lowered even at the stage of stirring and mixing by the stirring / turning mechanism 4 to the lowermost layer of the deposited filter medium 2, the entire amount of the filter medium 2 in the filter tank 1 is replaced with a new filter medium 2. A new filtration operation is performed. At this time, with the side wall plate 13 opened, the filter medium 2 holding the solid matter is carried out by the power shovel 14 and a new filter medium 2 is carried in. In addition, the filter medium 2 holding the solid matter taken out from the filtration tank 1 is deposited separately for a period required for the pyrolysis in a composting facility or the like, and is composted by aerobic fermentation.
