Problems solved by technology

However, the existing vertical flow sedimentation tanks have certain requirements on the hydraulic load and the properties of suspended matter. When the hydraulic load increases, it is easy to stir up the sediment in the mud collection well; when the suspended matter has a small particle size and a small density, Sedimentation efficiency will be greatly affected

Abstract

The invention discloses an integrated settling pond which comprises a filter layer (1), a water collection tray (2), a settling tank III (3), a settling tank I (4), a water inlet pipe (5), a settling tank II (6), a settling inclined plate I (7), a water outlet pipe (8), a sludge collection well I (9), a sludge collection well II (10), a sludge discharge pipe II (11), a sludge discharge pipe I (12), a settling inclined plate II (13) and a perforation aeration disc (14); the water collection tray (2), the settling tank III (3), the settling tank I (4), the water inlet pipe (5) and the settling tank II (6) are of a concentric structure; the settling inclined plate II (13) is arranged at the bottom of the settling tank II (6), the perforation aeration disc (14) is mounted in the sludge collection well II (10), and the water collection tray (2) is filled with the filter layer (1).The integrated settling pond has the advantages that (1) the settling efficiency is high, and the integrated settling pond has higher removal efficiency on small-particle and low-density suspended matters; (2) cleaning is convenient, and no blocking occurs; (3) the structure is compact, and the land is saved.

Description

technical field [0001] The patent of the invention belongs to the technical field of environmental protection, specifically relates to the treatment of suspended matter in agricultural waste water, industrial waste water, surface water and ground water, and is especially suitable for the treatment of industrial aquaculture circulating water. Background technique [0002] Sedimentation tanks have a variety of structural forms. Among them, the vertical flow sedimentation tank has a small footprint and high sedimentation efficiency. It has been widely used in industrial and agricultural wastewater treatment, surface water purification and other fields. However, the existing vertical flow sedimentation tanks have certain requirements on the hydraulic load and the properties of suspended matter. When the hydraulic load increases, it is easy to stir up the sediment in the mud collection well; when the suspended matter has a small particle size and a small density, The precipitatio...
