Embodiment 1

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

Embodiment 2

[0017] Example 2: According to the content of the invention, the aeration device described in Example 1 and the aeration water produced are treated as 5 inferior water samples, among which the COD 110mg / L, BOD 19.2mg / L, and total phosphorus 0.051 mg / L, total ammonia nitrogen 2.93mg / L, pollutant impurities 119mg / L, coliform bacteria 1.7×10 5 . The treatment method is to add 5-10mg / L PAL water purifier to the water sample and stir, then add 10-15% ozone micron exposure soda water after 3 minutes, and after 15-20 minutes, the suspended pollution impurities in the water sample will float on the water surface, and the water will be removed. The contamination impurities on the surface of the sample are removed, and the rest is clear, clean and transparent water. After inspection, the water quality is Class I water, COD5.6mg / L, BOD2.2mg / L, total phosphorus 4 . Pollution removal rates are above 90%.

Embodiment 3

[0018] Embodiment 3: According to the content of the invention and the aeration device described in Implementation 1 and the aeration water treatment produced is lower than the six types of water samples, which are 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, pollutant impurities 128mg / L, coliform group 2.9×10 5 . The treatment method is to add 5-10mg / L PAL water purifier to the water sample and stir, then add 10-15% ozone micron exposure soda water after 3 minutes, and after 15-20 minutes, the suspended pollution impurities in the water sample will float on the water surface, and the water will be removed. The contamination impurities on the surface of the sample are removed, and the rest is clear, clean and transparent water. After inspection, the water quality is Class I water, with COD 15.9mg / L, BOD 3.4mg / L, total phosphorus 0.086mg / L, total ammonia nitrogen 0.64mg / L, coliform ...

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 steam aeration device and a reverse floating sewage treatment method, belonging to the field of sewage treatment of ordinary rivers, rivers, lakes and seas with low-quality water. Background technique [0002] Prior to the present invention, domestic and foreign current methods of treating low-quality and low-quality water such as rivers, rivers, lakes, ditches, and seas all used sewage purifying agents to add precipitation to the traditional sewage treatment methods. Pollution suspended impurities can only be deposited at the bottom of the water body by precipitation method, so that the suspended pollutants in low-quality sewage cannot be easily cleaned out of the water body; or the suspended pollution in low-quality sewage can be filtered by various filtration methods Impurities, these traditional sewage treatment methods are very expensive, requiring a large amount of expensive sewage purification treatment a...
