Description

Technical Field

[0001] This application relates to the field of sludge treatment technology, and in particular to a highly efficient and harmless sludge treatment device. Background Technology

[0002] Sludge treatment refers to the process of treating, disposing of, and utilizing sludge generated during wastewater treatment. Sludge is generally composed of organic matter, inorganic matter, bacteria, viruses, etc. It usually originates from the wastewater purification process of wastewater treatment plants, industrial wastewater treatment, and other wastewater discharge sources. The purpose of sludge treatment is to reduce its volume, remove harmful substances, and ensure that the sludge can be safely disposed of or utilized as a resource.

[0003] Existing technologies typically employ microbial sludge treatment methods, mixing microorganisms into the sludge and treating it through microbial fermentation. Devices using microbial sludge treatment utilize motor-driven rotating rods and stirring rods mounted on a tank to agitate the sludge, rapidly mixing the microorganisms with it. A heating ring equipped with a controller and temperature sensor heats the sludge, raising its temperature to facilitate fermentation.

[0004] Microorganisms require additional nutrients during fermentation, but existing equipment makes it difficult to evenly distribute nutrients into wastewater, resulting in uneven nutrient distribution and an inability to obtain a balanced nutrient supply. This affects the metabolic activity of microorganisms and reduces the efficiency of sludge treatment, thus requiring improvement. Utility Model Content

[0020] 1. By combining a first motor, casing, and stirring rod, microorganisms can process sludge. Nutrients can be placed inside a conical tray via a storage cylinder, conduit, and metering valve. A second motor, rotating rod, gears, and gear ring enable the conical cylinder to drive a scraper, which agitates the nutrients inside the conical tray. The centrifugal force from the rotating scraper evenly distributes the nutrients into the sludge below, ensuring a balanced nutrient supply for the microorganisms, maintaining their metabolic activity, and improving sludge treatment efficiency.

[0021] 2. Sludge is added to the inside of the machine casing through the feed pipe, followed by the introduction of microorganisms. The first motor is then started, causing the stirring rod to rotate and mix the sludge and microorganisms, allowing the microorganisms to begin degrading the sludge. After a certain period of degradation, nutrients are added to the inside of the storage cylinder. The nutrients flow downwards through a conduit into the conical tray, with the flow rate controlled by a metering valve. Subsequently, the second motor is started, causing the rotating rod to rotate the gear, which in turn rotates the gear ring. This causes the conical cylinder to move the scraper, scraping the nutrients evenly into the sludge to provide nutrition to the microorganisms. Attached Figure Description
