Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, in particular to sludge dehydration and drying treatment equipment for sewage treatment. Background Art

[0002] In the process of sewage treatment, a large amount of sludge is generated. With the global emphasis on environmental protection and increasingly stringent sewage discharge standards, the amount of sewage treatment is increasing. For example, in urban sewage treatment plants, after sewage undergoes a series of physical, chemical and biological treatment processes, pollutants such as suspended solids and organic matter are aggregated to form sludge. These sludges usually contain a large amount of water, are large in volume, and have complex components, including microorganisms, organic debris, inorganic particles, etc. From an environmental protection perspective, if sludge that has not been effectively dehydrated and dried is randomly piled up or disposed of, it will cause serious pollution to the soil, water bodies and atmospheric environment. For example, during the stacking process of sludge with high water content, the pollutants in it may infiltrate into groundwater with leachate, polluting groundwater resources. At the same time, sludge will produce odorous gases during the decomposition process, affecting the living environment of surrounding residents. With the continuous increase in sludge production and the continuous improvement of environmental protection regulations, the requirements for sludge dehydration and drying equipment are also getting higher and higher.
