Description

Technical Field

[0001] The utility model relates to the technical field of sludge drying devices, in particular to a sludge drying device for water treatment. Background Art

[0002] Wastewater treatment refers to the physical, chemical, biological and other treatment methods for sewage to meet the discharge standards or reuse requirements. Pretreatment, including coarse screening, fine screening, grilles, sedimentation tanks, etc., is used to remove large particles, suspended matter and sediment in sewage. Biological treatment is the process of converting organic matter into inorganic matter using microorganisms. It is used to further improve the effect of sewage treatment, especially for removing microorganisms and difficult-to-degrade organic matter. Recycling technology, including sewage reuse and sludge resource utilization, reuses treated water resources and sludge to reduce water waste and sludge discharge. The main purpose of sludge drying equipment for water treatment is to reduce the moisture content of sludge and reduce the volume of sludge, thereby facilitating treatment and disposal.

[0003] Existing water treatment devices will form sludge after purifying water. The sludge is usually treated by first concentrating it to reduce its volume and then incinerating it. Although incineration can reduce the volume of sludge, the energy and organic matter therein are also destroyed at the same time, and resource recycling cannot be achieved. The incineration process may produce fly ash and harmful gases, such as sulfur dioxide, nitrogen oxides, heavy metals, and dioxins. If these substances are not properly treated, they will have a serious impact on the environment and human health. Therefore, in order to solve the above problems and treat sludge more reasonably and effectively, a sludge drying device for water treatment is proposed. Utility Model Content

Through circulating drying, the amount of sludge processed can be reduced, the sludge processing cost can be reduced, and the scraper pressure can be adjusted at will so that sludge with different dryness degrees can be scraped.
