POULTRY FARMING METHOD, ULTRAFINE BUBBLE MAKER FOR POULTRY FARMING, AND DRINKING WATER PREPARING DEVICE FOR POULTRY FARMING
The present invention feeds egg-laying poultry with drinking water containing ultrafine bubbles of air by using a drinking water supply device 1 installed in a poultry house. This drinking water supply device 1 is provided with: a bubble water tank 2 for storing water containing ultrafine bubbles of air; a bubble water preparing device 3 that adds the ultrafine bubbles of air by supplying the water in the bubble water tank 2 and prepares ultrafine bubble water; and a water storage tank 4 that stores the ultrafine bubble water supplied from the bubble water tank 2. The ultrafine bubble water of the water storage tank 4 is guided by a branch pipe 6 through a supply pipe 5 and is supplied as drinking water to egg-laying poultry by a water supplier 7 provided to the branch pipe 6. The remaining water in the branch pipe 6 is returned to the water storage tank 4 through a return pipe 8.
The present invention feeds pigs for meat with drinking water containing ultrafine bubbles of air by using a drinking water supply device 1 installed in a pigsty. This drinking water supply device 1 is provided with: a bubble water tank 2 for storing water containing ultrafine bubbles of air; a bubble water preparing device 3 that adds the ultrafine bubbles of air to the water from the bubble water tank 2; a second bubble water tank 4 that stores the ultrafine bubble water; a mixed fluid tank 5 for storing a mixed fluid of the ultrafine bubble water and a plant extract-mixed fermented liquid; a fermented liquid water tank 6 for storing an aqueous solution of the plant extract-mixed fermented liquid; and a water tank 7 for storing tap water. The liquids in the tanks are respectively guided to first to fourth farming areas A1, A2, A3, and A4, and are supplied to the pigs for meat by a water supplier 8.
This ultrafine bubble water preparing device 1 is provided with: a volute pump 3; an ejector 4; a cascade pump 6; a branch part P on the downstream side of the cascade pump 6; a return passage 7 connected from the branch part P to a portion between the ejector 4 and the cascade pump 6; a flow rate adjusting valve 9 and a first ultrafine bubble maker 2A which are provided in the return passage 7; a discharge path 8 connected to the branch part P; and a second ultrafine bubble maker 2B and a control device 13 which are provided in the discharge path 8. The control device 13 adjusts an air amount adjusting valve 5, the volute pump 3, the cascade pump 6, and the flow rate adjusting valve 9, on the basis of a measured value of a densitometer 10 in the discharge path 8 and measured values of first and second pressure gauges 11, 12 on the upstream and downstream sides of the cascade pump 6.
For manufacture of solid fuels by solidifying processing-object materials containing plastics, waste paper and waste wood, the processing-object materials inputted through an input port 12 are subjected to water injection so that their water content becomes 15 wt % or more, preferably 20 wt % or more, and then kneaded, compacted and extruded in three turns or less, being extruded from molding nozzles 53 of an end face plate 5. The water injection is performed by a water injection nozzle 31 from the input port 12 into a casing 11. Opening and closing of a solenoid valve 33 interposed on a water injection pipe 32 adjoining the water injection nozzle 31 is controlled based on a signal S1 derived from a temperature sensor 55 provided at a molding nozzle 53 of the end face plate. Such disadvantages as inflammation due to excessively high temperatures of the processing-object materials or worsened shape retention of solidified materials due to excessively low temperatures of the processing-object materials can be prevented.

METHOD OF REPLACING ARTIFICIAL LAWN AND ARTIFICIAL LAWN DISPOSAL APPARATUS
An existing artificial lawn filled with a filler is removed from the laying surface, and the removed artificial lawn is disposed of by a mobile artificial lawn disposal apparatus provided in the vicinity of the laying surface. The artificial lawn disposal apparatus comprises a single-screw crusher (11) for artificial lawn crushing mounted on a bed (10) of heavy-duty truck; a centrifugal separator (12) for separation of filler from artificial lawn body fragments; and a band dryer (13) for drying the filler. As the filler is recovered from the artificial lawn in the vicinity of the laying surface, there can be saved the labor and cost for transporting the artificial lawn to a crushing site and disposal site. Further, as the filler for use in a new artificial lawn can be promptly obtained by the recovery of the filler from the artificial lawn in the vicinity of the laying surface, there can be shortened the time for completion of replacing work.

SOLIDIFICATION PROCESSING METHOD AND SOLIDIFICATION PROCESSING APPARATUS
In the production of solid fuel by solidification of a processing object containing plastic, waste paper and waste wood, water is poured onto the processing object charged through charge port (12) so as to realize a water content of 15 wt.% or more, preferably 20 wt.% or more. The mixture is subjected to blending, compression and extrusion in three turns or less, and extruded out from shaping nozzle (53) of edge board (5). The water pouring is performed through water pouring nozzle (31) from the charge port (12) into casing (11). The opening/closing of electromagnetic valve (33) intermediately disposed on water pouring pipe (32) connectedto the water pouring nozzle (31) is regulated on the basis of signal (S1) from temperature sensor (55) fitted to the shaping nozzle (53) of the edge board. Consequently, there can be prevented the disadvantage of firing attributed to an excessive increase of the temperature of the processing object and the disadvantage of deterioration of the shape retention of solidified matter attributed to an excessive decrease of the temperature of the processing object.
