Description

Technical Field

[0001] The utility model relates to the technical field of odor control devices, in particular to a sewage odor control device. Background Art

[0002] Wastewater contains a large amount of particulate matter, hydrogen sulfide, ammonia, easily oxidized organic malodorous gases and oily substances, which cause the waste gas generated by the wastewater to have a bad smell and have a great destructive power on environmental hygiene. The waste gas is fugitive and can easily affect the surrounding environment. Therefore, the sealed collection of waste gas is a prerequisite for waste gas treatment. The most effective way for the existing sewage pool waste gas treatment system to collect waste gas from the pool is to cover and seal the sewage pool, and then ventilate through the air inlet and outlet, and pump the waste gas to the treatment device for treatment. When the waste gas is then passed into the alkaline oxidation tower for cleaning, since the waste gas contains many large particles of impurities, they are deposited inside the alkaline oxidation tower and are difficult to clean. Regular shutdowns are required to manually clean the inside of the alkaline oxidation tower to remove sediment, which is inconvenient to use. Utility Model Content
