Description

Technical Field

[0001] The utility model relates to the technical field of sludge, in particular to a sludge dewatering machine. Background Art

[0002] Sludge is a soft muddy substance consisting of a mixture of solid matter and water produced in water treatment, industrial production or other processes. It usually contains organic and inorganic substances, such as suspended particles, dissolved substances, bacteria, viruses, etc. These pollutants will be removed during sewage treatment and eventually deposited in the sludge. The composition of sludge depends on the source and treatment method, but in general, sludge contains a large amount of water, organic matter, inorganic matter, microorganisms and heavy metals. After proper treatment and processing, sludge can be used for many purposes, such as soil conditioner, fertilizer manufacturing, energy recovery, etc. When treating sludge, a dehydrator is needed to dehydrate the sludge for easy storage and transportation.

[0003] Sludge usually releases odors, which mainly come from gases produced by the decomposition of organic matter in the sludge, such as hydrogen sulfide, ammonia, etc. In addition, there may be some microorganisms and bacteria in the sludge, and their metabolic activities will also cause the production of odors. When workers operate near the dehydrator, they inhale a large amount of sludge odor, which may cause symptoms such as discomfort, headache, eye irritation and difficulty breathing, affecting their health.
