Alkaline waste water neutralization treatment equipment

摘要

PROBLEM TO BE SOLVED: To provide an alkaline wastewater neutralization treatment system capable of sufficiently neutralizing alkaline wastewater by utilizing combustion exhaust gas.;SOLUTION: The alkaline wastewater neutralization treatment system is equipped with a neutralization treatment tank 2 for neutralizing alkaline wastewater, and an exhaust gas feed means 20 for feeding the combustion exhaust gas to the neutralization treatment tank 2. In the alkaline wastewater neutralization treatment system, the combustion exhaust gas is fed to gas/liquid contact chambers 10, 12 of the neutralization treatment tank 2 in bubbles to neutralize the alkaline wastewater. The neutralization treatment tank 2 is equipped with an exhaust gas chamber 8 in which the combustion exhaust gas from the exhaust gas feed means 20 is flown, and the lower gas/liquid contact chamber 10 and the upper gas/liquid contact chamber 12 for applying gas/liquid contact to the alkaline wastewater. In the lower ventilation partition 26 and upper ventilation partition 28, a plurality of diagonally extending ventilation slits are provided. The combustion exhaust gas is passed through the ventilation slits to form bubbles, and fed to the alkaline wastewater.;COPYRIGHT: (C)2005,JPO&NCIPI
