Abstract

The invention relates to an efficient sewage precipitation device and method, and belongs to the technical field of sewage precipitation separation. The device comprises a body, an inner cavity of thebody is divided into three cavities which are a clear water cavity, a sewage cavity and a sludge cavity from top to bottom, a packing layer mounted on a net-shaped supporting plate is arranged between the clear water cavity and the sewage cavity, the edge of the net-shaped supporting plate is mounted on the inner wall of the body, a solid-liquid separation barrel is mounted at the bottom of the packing layer, a stand column is arranged in the solid-liquid separation barrel, the top of the stand column is fixed at the bottom of the packing layer, a conical baffle is installed at bottom of thestand column, the small-diameter end of the conical baffle is connected with the stand column, the conical baffle plate is positioned in the solid-liquid separation barrel, a water inlet is formed inthe side wall of the solid-liquid separation barrel, the water inlet is formed in the middle of the solid-liquid separation barrel and is connected with a water inlet pipe, the water inlet pipe penetrates through the body and is arranged in the tangential direction of the outer wall of the solid-liquid separation barrel, an overflow port is formed in the side wall of the top of the solid-liquid separation barrel, and an opening is formed in the bottom of the solid-liquid separation barrel. The technical problem of low precipitation efficiency of a sewage precipitation technology in the prior art is solved.

Description

technical field [0001] The invention relates to a high-efficiency sewage sedimentation device and method, belonging to the technical field of sewage sedimentation and separation. Background technique [0002] Sewage sedimentation devices are widely used in mine water treatment, high turbidity water treatment, high suspended solids wastewater treatment and reuse, blast furnace gas washing wastewater treatment, coal washing water treatment and power plant wastewater treatment. The sewage sedimentation device in the prior art generally uses the traditional coagulation sedimentation technology for sedimentation, which cannot fully separate the suspended solids in the sewage, resulting in excessively high inorganic components in the activated sludge of the subsequent biochemical system, reducing the sludge activity , generally have the defects of low sedimentation efficiency and high moisture content of sludge. Contents of the invention [0003] Aiming at the deficiencies of t...
