Abstract

The invention relates to a semi-buried integrated desulphurization wastewater treatment apparatus. The apparatus comprises a wastewater treatment zone, a dosing zone and a sludge treatment zone. The apparatus is designed in an integrated manner, a wastewater treatment flow completely adopts a buried design, the wastewater treatment zone is arranged underground, and all treatment facilities are designed in a wall sharing manner, and are connected through a guiding slot. Stirring facilities in the wastewater apparatus completely adopt underwater stirrers, so the space is saved, and the apparatus arrangement is compact. A medicine storage device shares the wall with a precipitation zone, and is arranged above a wastewater treatment flow, so a dosing device conveniently runs, and can be conveniently evacuated. A sludge treatment facility is arranged above the dosing reaction zone, and is positioned above the ground level.

Description

Technical field [0001] The invention belongs to the technical field of water treatment, and relates to a limestone-gypsum method desulfurization wastewater treatment device, in particular to a semi-buried integrated desulfurization wastewater treatment device. Background technique [0002] With the rapid development of my country’s energy industry and the construction of large-scale coal-fired power plants, fuel consumption continues to increase, SO 2 More and more emissions, the resulting air pollution is becoming more and more serious, the adoption of desulfurization measures has become imminent. SO 2 The control methods include pre-combustion desulfurization, in-combustion desulfurization and post-combustion desulfurization, namely flue gas desulfurization (FGD). Currently, flue gas desulfurization is considered to control SO 2 The most effective means of emissions. The limestone-gypsum method is the most widely used and most mature desulfurization process in the world. The d...
