Embodiment 1

[0015] The ozone micron aeration device of the present invention is such as figure 1 Shown is composed of high-pressure water pump, ozone generator water-steam mixing electrical control system, water-steam circulation control combination valve. The ozone generator 1 is connected to the water inlet pipe 5 through the ozone inlet and outlet pipes 2 and 13, and the ozone inlet and outlet valves 4 and 12 are connected to the water inlet pipe 5. The water inlet valve 7 and the water inlet pipe 5 are connected to the high pressure water pump 3 in turn, and then to the water vapor The mixed circulation control combined valve body 10 and the water outlet pipe 11 are connected in series; the water-vapor mixing electronic control system 9 synchronously controls the high-pressure water pump 3, the ozone inlet and outlet valves 4 and 12, the water inlet valve 7, the water-steam mixing circulation control combined valve body 10; the water pipe 8 Located between the high-pressure water pump 3 ...

Embodiment 2

[0017] Example 2: According to the content of the invention, the aeration device and the aeration water produced in Example 1 are treated as 5 poor water samples, and the poor five water samples contain COD 110mg / L, BOD 19.2mg / L, and total phosphorus 0.051 mg / L, total ammonia nitrogen 2.93mg / L, polluting impurities 119mg / L, colony of Escherichia coli 1.7×10 5 . The treatment method is to add 5-10mg / L PAL water purifier to the water sample and stir, add 10-15% ozone micron aeration water after 3 minutes, 15-20 minutes later, the suspended pollutant impurities in the water sample will float on the water surface to remove the water. Contaminated impurities on the sample surface, the rest is clear, clean and transparent water. The tested water quality is first-class water, COD5.6mg / L, BOD 2.2mg / L, total phosphorus 4 . The pollution removal rate is above 90%.

Embodiment 3

[0018] Example 3: According to the content of the invention and implementation 1, the aeration device and the aeration water produced is lower than the six types of water samples, which is lower than the COD 218mg / L, BOD 26.2mg / L, and total phosphorus in the six types of water samples. 0.65mg / L, total ammonia nitrogen 6.73mg / L, pollution impurities 128mg / L, coliform 2.9×10 5 . The treatment method is to add 5-10mg / L PAL water purifier to the water sample and stir, add 10-15% ozone micron aeration water after 3 minutes, 15-20 minutes later, the suspended pollutant impurities in the water sample will float on the water surface to remove the water. Contaminated impurities on the sample surface, the rest is clear, clean and transparent water. The tested water quality is first-class water, COD 15.9mg / L, BOD 3.4mg / L, total phosphorus 0.086mg / L, total ammonia nitrogen 0.64mg / L, and Escherichia coli group 1.2×10 3 . The pollution removal rate is above 90%.

Abstract

The invention relates to a sewage disposal method of an ozone micron aeration system and a converse floating type which is characterized in that the system is composed of high pressure pump, ozonizer, vapor mixing electronic control system, vapor mixing cycle control combined valve body, ozone inlet and outlet hydrovalve, inlet valve, inlet and outlet water pipe, ozonizer pipe, pressure meter. The system disposes sewage of low quality by producing ozone micron aeration water, adding different sewage cleansers (based on the difference of water quality characters) to the sewage of low quality to separate the pollution impurities to form impurity groups from the sewage of low quality, then injecting the ozone micron aeration water into sewage, and combining with the separated pollution impurity groups to make them float on the water surface in the sewage of low quality, subsequently sucking the pollution impurity on the water surface.

Description

Technical field [0001] The invention relates to an ozone micron aeration device and a reverse-floating sewage treatment method, which belongs to the field of sewage treatment of low-quality water of ordinary rivers, rivers, lakes and seas. Background technique [0002] Prior to the present invention, the domestic and foreign methods used in the treatment of low-quality water and sewage of rivers, rivers, lakes, ditch, sea, etc., all used the traditional sewage treatment method of sewage purifier plus sedimentation. Pollution suspended impurities can only be deposited at the bottom of the water body by the sedimentation method, so that the polluted suspended impurities in the low-quality sewage cannot be easily cleaned out of the water body; or use various filtering methods to filter the pollution suspension in the low-quality sewage Impurities, these traditional sewage treatment methods are very expensive, requiring a large amount of expensive sewage purification treatment agents...
