Description

Technical Field

[0001] The utility model relates to the technical field of wastewater deodorization in dead livestock and poultry incineration disposal projects, in particular to a VOC purification oxidation ionization tower for wastewater deodorization. Background Art

[0002] Incineration of dead livestock and poultry involves wastewater treatment. This wastewater often carries a strong odor, primarily from high concentrations of volatile organic compounds (VOCs), ammonia, hydrogen sulfide, and other gases. These gases not only cause serious pollution to the surrounding environment but also directly impact the health of workers and the quality of life of surrounding residents. Therefore, the development of efficient, economical, and environmentally friendly wastewater deodorization technologies is urgently needed.

[0003] Traditional wastewater treatment methods, such as biological, chemical and physical methods, can remove organic pollutants in wastewater to a certain extent, but they have limitations in deodorization efficiency, energy consumption, operating costs and secondary pollution. Especially when faced with high-concentration, highly toxic and difficult-to-degrade VOCs, traditional methods often find it difficult to achieve ideal treatment effects. Common wastewater deodorization equipment currently on the market, such as activated carbon adsorption, biological filters, chemical scrubbers, etc., can remove some malodorous gases, but have problems such as adsorption saturation, slow biodegradation rate, and high consumption of chemical reagents. Especially when dealing with high-concentration VOCs and complex organic matter, the effects of these methods are often unsatisfactory, and it is difficult to achieve continuous and stable operation.

[0004] Furthermore, large particles and lumps in wastewater can easily clog pipes and equipment, increasing treatment difficulty and impacting overall efficiency. Stirring alone can still easily clog and cause uneven mixing of the solution. Filtration alone cannot purify odors from wastewater and can still pollute the environment, reducing practicality.
