Description
Technical Field
The utility model relates to a waste water treatment technical field especially relates to a gaseous processing system of equalizing basin.
Background
The wastewater treatment system usually needs to be provided with a regulating tank for balancing due to the uneven change of water inflow and water quality so as to ensure the uniformity and stability of subsequent wastewater treatment. Because the water level in the regulating reservoir is constantly changing during the operation of the wastewater treatment system, the volume of the gas in the regulating reservoir is changed accordingly. When the water level of the adjusting tank is changed from low to high, gas needs to be discharged from the adjusting tank, and when the water level of the adjusting tank is changed from high to low, external gas needs to enter the adjusting tank, so that the normal operation of the adjusting tank can be ensured. At present, in order to prevent the gas in the regulating reservoir from escaping, the regulating reservoir is usually closed by a cover, the balance of the gas in the regulating reservoir is generally realized by a vent hole on the top of the reservoir, and the gas in the regulating reservoir is usually treated as odor.
When the treated wastewater is high-concentration organic wastewater with daily water inflow and water quality periodically and greatly changed, the volume required for regulating balance is large due to large daily water inflow and water quality periodic change amplitude, the retention time of the wastewater in the regulating tank is long, and high-concentration organic matters in the wastewater inevitably generate combustible and explosive gases such as methane under the action of anaerobic microorganisms. If adopt traditional blow vent mode to carry out gaseous regulation in the pond, when the water level changes low by the height in the equalizing basin, the air can get into in the pond through the blow vent at equalizing basin top, and when the water level changes high by the low, the mixed gas that contains air and marsh gas in the pond can get into deodorization system through the blow vent at equalizing basin top again. Since the deodorization system has no treatment capability for the mixed gas of biogas and air, the mixed gas containing biogas and air will eventually escape after the deodorization system. The mixed gas is easy to combust and explode, so that safety accidents are easily caused, and the mixed gas is not suitable for being used as pure methane to enter a methane storage cabinet or being used for treating odor.
Therefore, a conditioning tank gas treatment system with high safety is urgently needed.
