The utility model relates to the technical field of
waste gas treatment, in particular to a biochemical
pool waste gas collecting and treating device which comprises a main body, the top of the main body is fixedly connected with a
waste gas pretreatment component, and the side surface of the main body is provided with a biological attachment gas filtering component; according to the utility model, the gas collecting hood adopts a negative pressure type design, so that waste gas generated by the biochemical
pool can be effectively collected, the waste gas is conveyed to a follow-up
treatment system through the waste gas conveying pipeline, and the waste gas is firstly cooled by the condenser, so that
water vapor in the waste gas is condensed into
liquid water; the temperature and
humidity of the waste gas are reduced,
fog drops in the waste gas are removed through the
demister, the influence of the
fog drops on subsequent treatment equipment is prevented, the tank body is filled with the volcanic biological filler, and when the waste gas is in contact with the volcanic biological filler, microorganisms on the volcanic biological filler degrade and absorb harmful gas in the waste gas, so that the harmful gas in the waste gas is degraded and absorbed; the waste gas treatment device is simple in structure, high in treatment efficiency and capable of effectively removing harmful gas in waste gas of the biochemical
pool.
