Description

Technical Field

[0001] The invention relates to the technical field of urban sludge purification and treatment equipment, in particular to an urban sludge deodorization and collection device. Background Art

[0002] With the development of economy and the acceleration of industrialization, the amount of various pollutants such as urban sewage is increasing. Sludge is the product of sewage treatment. It is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content (up to 99% or more), high organic content, easy to rot and stink, fine particles, small specific gravity, and colloidal liquid. If it is not treated and discharged arbitrarily, it will cause serious pollution to the environment. However, there are two main reasons for the difficulty of sludge treatment: first, sludge will emit a foul odor, which contains harmful gases such as hydrogen sulfide, nitrogen oxides, and ammonia, and has a large amount of irritating odor and particulate matter, which pollutes the environment and endangers human health; second, the high water content makes it difficult to dry. Mechanical dehydration of sludge is actually sludge concentration, in which biomass is not affected, and the sludge drying and heating method is from the surface to the inside, resulting in the formation of a dry crust on the surface of the material, resulting in a long drying time and uneven drying of the material.
