Spiral-flow type crystal phosphorous removal reactor

Abstract

The invention relates to a spiral-flow type crystal phosphorous removal reactor comprising an underflow area, a hydraulic cyclone area and an overflow area from bottom to top, wherein the underflow area comprises a bottom plate to which a lower column body is connected; the lower column body is provided with a recovery pipe and a return pipe; the hydraulic cyclone area comprises an inverted horn mouth, a cone and a middle column body; the inverted horn mouth extends into the underflow area, and the upper end of the inverted horn mouth is connected with the lower end of the cone; the cone extends into the underflow area, and the upper end of the cone is connected with the lower end of the middle column body; the upper end of the middle column body is connected with a cover plate; the middle part of the cover plate is connected with the overflow pipe; two water inlets and two drugging openings which are respectively symmetric are arranged on the middle column body; the overflow area comprises an upper column body connected with the cover plate; the middle part of the upper column body is provided with a packing layer; a water discharging weir is arranged above the packing layer; and a slag removal pipe and a water discharging pipe are arranged on the upper column body. The spiral-flow type crystal phosphorous removal reactor can be used for realizing rapid separation of granular crystallized phosphor salt and is suitable for treating phosphonium-containing waste water on different scales.

Description

technical field [0001] The invention belongs to the technical field of phosphorus removal devices, in particular to a cyclone crystallization phosphorus removal reactor. Background technique [0002] With the development of industry and agriculture and the improvement of human living standards, a large amount of phosphorus-containing urban sewage, industrial wastewater and agricultural (breeding) sewage are discharged into water bodies. Taking 2008 as an example, the discharge of wastewater in my country was 57.20 billion tons. Based on the average phosphorus concentration of wastewater of 10 mg / L, the discharge of phosphorus-containing wastewater nationwide was 572,000 tons, which led to serious environmental pollution and ecological damage. Outstanding performance Eutrophication of water bodies. The national water environment quality status in 2008 pointed out that the eutrophication problem of lakes in my country is prominent, and eutrophic lakes (reservoirs) accounted fo...
