Description

Technical Field

[0001] The utility model relates to the technical field of sludge dehydration equipment, in particular to an oily sludge dehydration device for sewage treatment. Background Art

[0002] Sewage treatment refers to a water treatment technology that processes wastewater generated in production, life and other activities through a series of treatment processes to meet national emission standards and discharge requirements, thereby protecting water resources from pollution. The purpose of sewage treatment is to reduce or remove pollutants in sewage to protect aquatic biological resources and water environment safety. In the sewage treatment process, common treatment processes include physical treatment, chemical treatment and biological treatment. Among them, physical treatment mainly refers to the removal of suspended matter, organic matter, pathogens, etc. in sewage through physical effects such as filtration and adsorption; chemical treatment mainly refers to the removal or conversion of pollutants by adding chemical agents such as disinfection, oxidation, and reduction to change the properties of sewage; and biological treatment mainly relies on the action of microorganisms, such as nitrification, denitrification, denitrification, desulfurization, and phosphorus removal to remove pollutants in sewage. Different treatment processes are suitable for different water quality conditions and pollutant compositions. Generally speaking, sewage treatment plants will select a suitable combination of treatment processes based on the characteristics of the influent water quality to form a complete set of treatment processes. The treated effluent needs to be strictly monitored to ensure that it meets the emission standards before it can be finally discharged into the environment. In general, sewage treatment is an important environmental protection task. It is related to the sustainability of human life and production, as well as the safety and health of the ecological environment.

[0003] Sewage treatment plants produce a large amount of oily sludge every year, which accounts for a large proportion of the solid waste treatment volume. This sludge not only contains a large amount of grease, but also has an extremely high water content, which means that most of the sludge is actually water rather than useful grease components. At present, the plant lacks sludge dewatering equipment and effective treatment measures, and is unable to separate the oil pollution, resulting in high treatment costs. The existence of this problem puts a double pressure on both the environment and the economy. First, the high water content of sludge increases the complexity of treatment, requiring more energy and resources in the treatment process, thereby increasing treatment costs. Secondly, the grease contained in these sludges is a valuable resource, but due to the lack of effective separation technology, most of the grease cannot be recycled and utilized, resulting in a waste of resources.
