Description

Technical Field

[0001] The utility model relates to the technical field of anaerobic tower equipment, in particular to a UASB anaerobic tower and a water distribution structure thereof. Background Art

[0002] Anaerobic reactors, also known as anaerobic towers, are commonly constructed in IC, UASB, and EGSB configurations. They are primarily used to treat high-concentration organic wastewater and are widely used in light industries such as food, beverages, fermentation, papermaking, and landfill leachate. The UASB anaerobic tower consists primarily of a water distributor, riser, downcomer, three-phase separator, top cover, and gas-liquid separator.

[0003] When the existing UASB anaerobic tower and its water distribution structure are in use, a large amount of fixed sludge is easily deposited at the bottom of the separator in the UASB anaerobic tower, and the discharge efficiency is relatively slow, which affects its reliability. In addition, the water distribution node usually uses a filter to filter large particles in the water. When the filter is used for a long time, the large particles in the water easily clog the filter, which will greatly reduce the flowability of the water supply channel. Therefore, regular equipment maintenance is required, which is costly. Utility Model Content
