摘要:
Developed is a technique according to which a nitrogen-containing bicyclic heterocyclic compound can be manufactured directly from nitrogen-containing heterocyclic compounds in a short period of time through a small number of steps without using expensive agents and a starting material that takes time and effort to synthesize. A method for manufacturing a nitrogen-containing bicyclic heterocyclic compound includes a synthesis step of synthesizing a nitrogen-containing bicyclic heterocyclic compound such as bipyrimidine, bipyrazine, or biquinoline by reacting, in a reaction solvent, one nitrogen-containing heterocyclic compound and another nitrogen-containing heterocyclic compound with a solution containing an alkali metal.

Upper and lower dampers (11, 12) are provided in a vertical chute (6) of a waste-feeding apparatus (1). The upper and lower dampers (11, 12) have a sealing function that inhibits external air from entering a gasifier (20) and configured to be alternately opened and closed. The lower damper (12) includes a lower left damper (12 L ) and a lower right damper (12 R ) configured to be opened and closed through lower supporting shafts (12p), provided on opposite portions of an inner wall of the vertical chute (6) and parallel to a center line (Lc), the center line (Lc) extending in a longitudinal direction and passing through the center in a width direction of the waste-conveying device (7). A merged line (12m) defined by distal portions of the lower left damper (12 L ) and the lower right damper (12 R ) in a closed state is located above the center line (Lc) .

Disclosed is a waste treatment technique characterized in that it comprises: blowing a fluidizing gas from around a mixture discharge port (29) to form a first fluidization region (15) having a degree of fluidization of the fluidizable particles which is set to an extent allowing waste (18) to be accumulated on fluidizable particles (12), while blowing a fluidizing gas between the first fluidization region (15) and an opposite-side wall (25) at a higher flow velocity to form a second fluid region (16) having a degree of fluidization of fluidizable particles (12) greater than that in the first fluidization region (15), whereby the fluidizable particles (12) are mixed with the waste(18) to gasify the waste (18); and supplying waste (18) from a supply-side sidewall portion (24) onto the fluidized bed (14) to cause the waste (18) to be accumulated on the first fluidization region (15) while causing the accumulated waste (18) to be moved into the second fluidization region (16) step-by-step.
摘要:
An object is to provide a fresh water generating apparatus that is capable of efficiently and stably producing fresh water. Provided is a fresh water generating apparatus equipped with a seawater-treating reverse osmosis membrane device that produces fresh water from seawater by a reverse osmosis membrane, including a mixing section that mixes wastewater as dilution water with seawater to produce mixed water, and a first seawater-treating reverse osmosis membrane device that acts as the seawater-treating reverse osmosis membrane device to filter the mixed water, in which the apparatus is configured so that used water that is wastewater resulting from the use of the produced fresh water as service water is mixed as dilution water with seawater at the mixing section.

Provided is a dehumidifier including an adsorption column allowing a to-be-treated gas produced by electrolysis of water to circulate therethrough so as to allow moisture in the to-be-treated gas to be adsorbed therein, wherein the adsorption column includes an adsorbent capable of adsorbing moisture, a column body having a housing region containing the adsorbent, and a heating unit arranged within the column body and capable of heating the adsorbent so as to cause desorption of the adsorbed moisture from the adsorbent, and the column body is a tube having a bent portion.
摘要:
An object of the present invention is to provide a fresh water generating apparatus that is capable of efficiently producing fresh water according to an intended use, while utilizing wastewater. Provided is a fresh water generating apparatus equipped with a seawater-treating reverse osmosis membrane device that produces fresh water from seawater by a reverse osmosis membrane, which includes: a mixing section that mixes wastewater as dilution water with a portion of seawater to be subjected to membrane treatment to produce mixed water; a first seawater-treating reverse osmosis membrane device that acts as the seawater-treating reverse osmosis membrane device to filter the mixed water; and a second seawater-treating reverse osmosis membrane device that acts as the seawater-treating reverse osmosis membrane device to filter the remaining portion of the seawater to be subjected to membrane treatment, in an unmixed state with the dilution water.
摘要:
An object is to provide a sea water desalinating method that is capable of efficiently producing purified water, such as fresh water, from unpurified water, such as sea water. There is a step of carrying out a wastewater treatment by subjecting inorganic wastewater to precipitation and separation. Thus obtained supernatant water is further filtered e.g. by sand filtration means, microfiltration or ultrafiltation and the permeate is directed to the reverse osmosis unit. The RO concentrate is considered low salt concentration water and is mixed, as diluent water, into sea water to produce mixed water. The mixed water prepared by the mixing is finally subjected to reverse osmosis membrane filtration, thereby generating fresh water.
