The invention discloses a deodorizing device and a deodorizing method of a
sludge storage pool. The deodorizing device comprises a stirrer, a
pool cover, a high-energy
ion deodorizing device which is communicated with the
sludge storage pool through a first pipeline and a primary foul
gas concentration detection device which is arranged on the first pipeline; the stirrer comprises blades, a stirring shaft and a drive mechanism, wherein each blade is provided with a plurality of
aeration holes, the stirring shaft is provided with a gas inlet passage which is communicated with each
aeration hole, and the stirring shaft penetrates through the
pool cover; the
pool cover is provided with a stirring shaft installation hole and a foul gas discharging opening, the gas inlet end of the gas inlet passage is connected with the foul gas discharging opening, and the pool cover and the
sludge storage pool form a
closed space. The deodorizing method comprises the following steps: step A, enabling the sludge storage pool to stay at a
closed state; step B, stirring the sludge in the pool by utilizing the stirring device, and conveying air into the pool through the stirring blades; step C, extracting the foul gas by utilizing the high-energy
ion deodorizing device, and generating high-energy ions to decompose the foul gas. The deodorizing device and deodorizing method are specially used for deodorizing the sludge storage pool of a
sewage treatment factory; moreover, the deodorizing effect is good, the stable emission on standard can be realized, and the environmental
pollution can be avoided.
