Embodiment 1

[0036] Adopt 4 aerators of the present invention to be placed in a certain pond in Miyun County, Beijing (surface area 26m2) 2 ) shore, the pond water is treated, before and after the aeration device runs for 48 hours, the DO and BOD in the pond water 5 , COD, SS, oil, NH 3 -N, TN and TP concentrations are detected, and the odor (H 2 S) detect, the results are shown in Table 1 below.

[0037] Table 1 is a list of pollutant changes in pond water before and after being treated by the suspension aeration device with water body restoration function of the present invention

[0038]

[0039]

[0040]It can be seen from Table 1 that the DO content in the pond water increased by 4.41 mg / L after being treated with the suspended aeration disc with water restoration function. BOD 5 , COD, SS, petroleum, NH 3 The removal rates of -N, TN and TP were 46.67%, 64.61%, 71.64%, 72.12%, 89.76%, 89.22% and 84.20%, respectively. Odor (H 2 The removal rate of S) is 96.15%, and the tre...

Embodiment 2

[0042] One aeration device of the present invention is placed in a park lake in Beijing, and the air compressor is fixed on a barge to treat the lake water. Before and after the device runs for 48 hours, DO and BOD in the lake water will be treated. 5 , COD, SS, oil, NH 3 -N, TN and TP concentrations were detected, and the odor (H 2 S) detect, and the results are shown in Table 2 below.

[0043] Table 2 is a list of pollutant changes in lake water before and after being treated by the suspension aeration device with water body restoration function of the present invention

[0044] serial number

[0045] It can be seen from Table 2 that the DO content in the lake water increased by 4.57 mg / L after being treated with the suspended aeration disc with water restoration function. BOD 5 , COD, SS, petroleum, NH 3 The removal rates of -N, TN and TP were 36.05%, 52.92%, 67.03%, 68.85%, 90.15%, 87.71% and 86.46%, respectively. Odor in the atmosphere at 1 meter from the s...

Abstract

The invention discloses a suspending aeration device with a water body restoration function. The suspending aeration device comprises a gas distribution region, a gas-water mixing region and an aeration region, wherein the thee independent regions are arranged and combined into an integral structure from bottom to top; a corundum aeration plate and an air cavity connected with the corundum aeration plate are arranged in the air distribution region; the air cavity is connected with an externally-arranged air source device; three aeration holes with different apertures are formed in the corundum aeration plate; the gas-water mixing region is in an arc-shaped cavity structure of which the bottom part is thicker than the upper part; the internal angle of the bottom part and the external angle of the top part of the gas-water mixing region are arc-shaped; a plurality of long oval injection holes are evenly distributed in the middle part of the gas-water mixing region; an aeration top plate is adopted by the aeration region; and the diameter of the aeration top plate is greater than that of the top part of the gas-water mixing region.

Description

technical field [0001] The invention relates to the field of water treatment equipment for environmental protection, in particular to a suspended aeration device with water body restoration function. Background technique [0002] Suspension (pontoon) surface aerator is used in sewage treatment, using certain methods and equipment to forcefully add air to the sewage, so that the sewage in the pool is in contact with air to oxygenate, and stir the liquid to accelerate the oxygen in the air to the liquid. The transfer of the suspended matter in the pool prevents the sinking of the suspended matter in the pool, strengthens the contact between the organic matter in the pool, microorganisms and dissolved oxygen, and oxidizes and decomposes the organic matter in the sewage. This kind of forced aeration equipment in the sewage is called aeration equipment. The aeration equipment is suspended on the surface of the water body and is called a suspended (pontoon) surface aerator. The s...
