Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a slag retaining plate for a radial flow sedimentation tank. Background Art
[0002] Radial flow sedimentation tanks are mostly circular in plan, but there are also square ones. The diameter (or side length) is 6-60m, and the maximum can reach 100m. The water depth around the pool is 1.5-3.0m, and the pool bottom slope should not be less than 0.05. Wastewater enters the pool from the water inlet pipe in the center of the pool and flows slowly around the pool along the radius. Suspended matter settles during the flow and enters the sludge hopper along the slope of the pool bottom, and clarified water overflows from the pool periphery to the canal. Radial flow sedimentation tanks mostly use rotary scrapers to collect sludge. The scraper scrapers scrape the sludge that sinks to the bottom of the pool to the sludge hopper in the center of the pool, and then discharge it by gravity or sludge pump. In order to meet the sludge discharge requirements of the scraper, the pool bottom slope of the radial flow sedimentation tank is gentle.
[0003] A slag retaining plate is required when the radial flow sedimentation tank is in use. The existing slag retaining plate has a fixed overall height. When the wastewater is small, the slag is difficult to clean, and needs to be improved. Utility Model Content
