Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a chemical wastewater desulfurization processor. Background Art

[0002] Wastewater refers to the general term for water discharged during residential activities and runoff rainwater. It includes domestic sewage, industrial wastewater, and other unused water such as initial rain runoff into drainage pipes. It generally refers to water that cannot be recycled after certain technical treatment or water that cannot meet certain standards for purification after primary pollution.

[0003] In some production processes, a certain amount of wastewater will be generated, and hydrogen sulfide generated in the production is easily soluble in the wastewater. According to the chemical properties of hydrogen sulfide, hydrogen sulfide is easily soluble in water, and reacts with oxygen in the air to produce elemental sulfur and water. If discharged directly, low-concentration hydrogen sulfide has a "rotten egg" smell, which pollutes the surrounding environment. High concentrations of hydrogen sulfide can cause damage to the human respiratory tract. Therefore, it is very important to remove hydrogen sulfide in wastewater. A device for removing hydrogen sulfide from wastewater is disclosed in a public patent (patent number: CN219689471U). The electric slide rail in the wastewater pool can drive the support plate, so that the contact area between air and wastewater is increased during the process of gas passing into the wastewater pool. In addition, an interference mechanism is provided. During the process of gas passing, the rotation of the blades on the support column can increase the agitation of the liquid around the air inlet pipe, thereby increasing the amount of air dissolved and the reaction efficiency. However, this device does not clean and collect elemental sulfur, and the subsequent treatment is not perfect. In addition, the wastewater pool is in an open state, and the hydrogen sulfide gas in the wastewater is easily diffused in the air to harm the health of the staff. Utility Model Content
