Embodiment 1

[0041] refer to figure 1, The system for removing environmental hormone pollutants and black odor in water body includes: ozonation pure oxygen preparation device 1 and several rotating nozzles 2. The ozonated pure oxygen preparation device 1 is used to output ozonized pure oxygen with a pressure of 0.05 to 0.2 MPa. The ozonated pure oxygen is a mixed gas of ozone and pure oxygen, wherein the volume percentage of ozone can be determined according to the water body to be treated. The situation is set between 4% and 15%, for example, it can be set at 5.5%, 7%, 11%, etc., and it is usually set at 6% to 10%. Several rotating nozzles 2 are arranged in the water body 100 to be treated, and its air inlet pipe is connected to the output end of the ozonated pure oxygen preparation device 1, and is used for fully mixing the ozonated pure oxygen output by the ozonated pure oxygen preparation device 1 with the water body to be treated. mix.

[0042] Wherein, the ozonation pure oxygen pr...

Embodiment 2

[0049] refer to image 3 , embodiment 2 further increases the dissolved oxygen water preparation device 3 on the basis of embodiment 1, and the dissolved oxygen water preparation device 3 contains an axial flow pump 31 and an air-water mixer 32, and the axial flow pump 31 is used to extract water from the water body to be treated The air-water mixer 32 is connected to the water outlet of the axial flow pump 31 , and the air inlet is connected to the output end of the pressurizer 12 . The air-water mixer 32 quickly mixes the pressurized pure oxygen with the water flow drawn from the water to be treated by the axial flow pump 31 to prepare high-concentration dissolved oxygen water with a dissolved oxygen concentration of 80-120mg / L, which is sent into the Inside the tubular body 21 of each rotary nozzle 2 . That is to say, in embodiment 1, what is sucked into the tubular body 21 of the rotary nozzle 2 is sewage to be treated, while in embodiment 2, what is sucked into the tubul...

Embodiment 3

[0052] Embodiment 3 provides a kind of boat that removes environmental hormone pollutants and black odor in the water body, wherein the rotary nozzle 2 adopts figure 2 Rotating nozzle shown. refer to Figure 4 a, b, the ship provided by Example 3 for removing environmental hormone pollutants and black odor in water bodies includes: a hull 4, an ozonated pure oxygen preparation device 1, several rotating nozzles 2 and a dissolved oxygen water preparation device 3. in,

[0053] The ozonated pure oxygen preparation device 1 is installed in the hull 4, and is used to output ozonated pure oxygen with a pressure of 0.05-0.2 MPa. The ozonated pure oxygen is a mixed gas of ozone and pure oxygen, wherein the volume of ozone is 100 Mineral content is 4% ~ 15%. The ozonated pure oxygen preparation device 1 has an oxygen generator 11 , a pressurizer 12 and an ozone generator 13 . The pressurizer 12 is connected to the output end of the oxygen generator 11, and is used to pressurize t...

Abstract

The invention relates to a method and a system for removing environmental hormone type pollutants and black and odorous matter in water bodies. The method comprises the steps that: pure oxygen is pressurized to 0.05 to 0.2MPa and is introduced into an ozone generator, and ozonized pure oxygen with the ozone volume percentage rate being 4 percent to 15 percent; and a plurality of rotary spray nozzles or microporous titanium plate aerators are arranged in the water bodies to be treated, and the ozonized pure oxygen and the water bodies to be treated are fully mixed through the rotary spray nozzles or the microporous titanium plate aerators. The system comprises an ozonized pure oxygen preparation device and a plurality of rotary spray nozzles, wherein the rotary spray nozzles are arranged in the water bodies to be treated, in addition, air inlet pipes are connected with the output end of the ozonized pure oxygen preparation device, and further, the system also comprises a dissolved oxygen water preparation device which provides high-concentration dissolved oxygen water for the rotary spray nozzles. The method and the system have the advantages that color and smell type substances and environmental hormone type pollutants of the water bodies can be simultaneously removed, the oxygen consumption rate of the water bodies can be greatly reduced, and the self cleaning capacity of the water bodies is improved.

Description

technical field [0001] The invention relates to water environment restoration, and is a multi-effect treatment method and system suitable for black and odorous water bodies, especially suitable for urban landscape rivers that are severely polluted to cause black and odorous water bodies and excessive concentrations of environmental hormone pollutants. Background technique [0002] In the process of urbanization, due to imperfect sewage collection and treatment and non-point source pollution control systems, a large number of pollutants enter the urban landscape rivers, resulting in the exhaustion of dissolved oxygen in the rivers, and serious "black and odorous" phenomena in water bodies. After the water body enters the anaerobic stage, anaerobic microorganisms reproduce in large numbers, and acidify and decompose a large amount of organic matter in the water body and sediment, producing various volatile organic compound intermediates, and the water body begins to have a putr...
