Description

technical field [0001] The invention relates to the field of water body purification, in particular to an air flotation phosphorus removal purification device and a control system. Background technique [0002] Industrial wastewater, domestic sewage and other wastewater contain a large amount of phosphorus elements, and industrial wastewater and domestic sewage are directly discharged into lakes and rivers, which will lead to eutrophication of lake water and damage the ecological environment. [0003] According to the patent application number 2020213387390, a deep phosphorus removal air flotation device includes a base, the lower side of the base is provided with universal wheels, the inner side of the base is provided with a bottom plate, and the upper end of the bottom plate is fixedly installed with a column. The upper end of the column is fixedly equipped with a reaction tank, the left side of the reaction tank is provided with a drain, the right side of the reaction ta...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the problems of insufficient dissolution of existing phosphorus removal drugs, low dissolution efficiency, and unstable operation of phosphorus removal equipment in the prior art, the present invention proposes an air flotation phosphorus removal purification device, including a purification pool, outside the purification pool There is an aeration device on one side, the aeration tube of the aeration device runs through the purification tank, and a number of micro-air holes are opened on the aeration tube, and a partition with a window is arranged across the purification tank, and the partition separates the purification tank into an aeration tank. Gas purification area and sedimentation area; a feeding unit is provided above the sedimentation area; the feeding unit includes a screw mandrel, a feeding platform and a feeding barrel; the screw mandrel is symmetrically rotated and connected to the platforms on both sides of the upper port of the purification tank, The screw rod is connected to the supporting legs of the feeding table. The feeding table is symmetrically opened with through holes. The upper hole end of the through hole is equipped with a feeding cylinder, and the bottom of the feeding cylinder is provided with a No. 1 discharge hole; the aeration device is Wuxi Haituo Environmental Protection Equipment Technology Co., Ltd. The device developed by the company connects the outlet end of the aeration device with the aeration pipe, centrally circulates the gas into the aeration pipe, and places the aeration pipe inside the purification tank; removes industrial wastewater, domestic sewage and other wastewater from the The water inlet at the bottom of the purification tank is driven into the purification tank, and the aeration device is activated through the aeration system. The aeration device generates micro-nano bubbles and acts on the sewage. The gas-liquid atomization of the bubbles and sewage occurs and forms in the purification tank. 1500mm-2000mm thick micro-nano bubble filter layer, at the same time through the feeding system, control the movement of the feeding platform after it comes up in the purification tank, so that the aluminum salt dephosphorization drug inside the feeding cylinder is evenly sprinkled in the purification tank, and the drug mixes with the sewage in the purification tank , and under the promotion of the filter layer, accelerate and improve the reaction of drugs and sewage, purify the pollution factors such as solid suspended solids and grease in sewage, and improve the purification efficiency and operation stability of the aeration device for sewage
