Abstract:
A desalination apparatus utilizing solar energy, and a method of operating the same. This apparatus is provided with a solar heat collector 12 for heating a heating medium 13 with solar energy, a heat exchanger 92 cooperating with an evaporation can 60 so as to subject the heating medium and raw water 62 in the evaporation can to heat exchange and generate water vapor 63 therein, a condenser 98 cooperating with a raw water tank 72 so as to receive the vapor 63 from the evaporation can, cool the vapor by subjecting the vapor and raw water in the raw water tank to heat exchange and obtain distilled water, a distilled water tank for storing distilled water, an evacuating means for evacuating the evaporation can and depressurizing the inside so as to promote the generation of vapor in the evaporation can, and a means for supplying raw water to the evaporation can. When a plurality of evaporation cans 60 are provided, a condenser cooperating with the evaporation cans is provided so as to receive the vapor 63 from an upstream-side evaporation can, cool the vapor with the raw water in a downstream-side evaporation can and thereby produce distilled water, and also heat the raw water in the downstream-side evaporation can and generate vapor.

PROBLEM TO BE SOLVED: To provide a method and an apparatus for treating a biodegradable plastic bag in which garbage is collected, which can produce good compost and can reduce the amount of residues to be discharged outside a composting facility. SOLUTION: The method for treating the biodegradable plastic bag containing the garbage is characterized in the garbage 13 collected by the biodegradable plastic bag is shredded and sorted by a selective shredding sorting device 1 and a material 13 primarily comprising the biodegradable plastic bag after garbage 14 has been sorted is decomposed by fermentation treatments 4, 5. The material 14 primarily comprising the garbage which has been shredded and sorted is subjected to fermentation treatments 9, 10 separately from the material primarily comprising the biodegradable plastic bag. Fermentation treatment of the material primarily comprising the biodegradable plastic bag can be performed with addition of compost.
Abstract:
PROBLEM TO BE SOLVED: To provide a water culture apparatus for plant, capable of generating utilities such as water and electric power necessary for the culture of plant by solar energy and minimizing or eliminating the use of external utilities. SOLUTION: This water culture apparatus is at least provided with a roofed culture chamber 100, a water-culture facility 200, a photovoltaic power generation apparatus 400 and a desalination apparatus 300. The photovoltaic power generation apparatus 400 supplies the total or a part of power and the desalination apparatus 300 supplies the total or a part of water necessary for the water culture of plant. The apparatus is further provided with a water-temperature controlling apparatus 500 to control the temperature of the water-culture liquid of the water culture facility 200 to a prescribed level suitable for water culture.
