Immersion-type precipitation device and precipitation system

Abstract

The invention discloses an immersion-type precipitation device and a precipitation system. The precipitation system comprises a precipitation pond, a partition plate and the immersion-type precipitation device; the immersion-type precipitation device comprises a pond-shaped precipitation tank, a plurality of precipitation assemblies which are arranged in the precipitation tank, and a sludge hopper; a water inlet and a water outlet are respectively formed in the two ends of the precipitation tank; each precipitation assembly comprises a first inclined plate and a second inclined plate which are arranged in an inclined manner relative to the horizontal plane; the first inclined plates and the second inclined plates are arranged in the length direction of the precipitation tank; the upper end of each second inclined plate is connected with one side surface of the corresponding first inclined plate; the upper end of the sludge hopper is communicated with the precipitation tank. On one hand, the immersion-type precipitation device can be directly placed into a sewage channel for performing sewage precipitation treatment, moreover, the position can be moved according to requirements, the capital construction cost of precipitation equipment is reduced, and the immersion-type precipitation device can be utilized secondarily; on the other hand, the sewage moves in a horizontal flow manner along the first inclined plates and the second inclined plates, so that the flowing stability of the sewage is ensured, and the precipitation efficiency and the precipitation load of the sewage are improved.

Description

technical field [0001] The invention relates to sewage treatment technology, in particular to an immersion sedimentation device and a sedimentation system. Background technique [0002] Sedimentation treatment of sewage is an indispensable step in the sewage treatment process. At present, the main devices for sewage sedimentation include sedimentation tanks, inclined tube settlers, inclined plate settlers, etc. Among them, the inclined tube settler and inclined plate settler are based on their Higher precipitation efficiency has been recognized by people. [0003] Inclined tube settler and inclined plate settler are high-efficiency combined settlers designed according to the shallow pool sedimentation theory. Specifically, many dense inclined tubes or inclined plates are set in the settlement area to make the suspended impurities in the water flow in the inclined tubes or Sedimentation occurs in the inclined plate, and the water flows upward along the inclined tube or incli...
