Problems solved by technology

But over time, drug-resistant algae will appear in the water, the effectiveness of the algicide will gradually decrease, the interval between dosing will become shorter and shorter, and the dosage will increase, and the species of algicide must be replaced frequently. It will also cause secondary pollution to the water environment

Embodiment 1

[0027] Embodiment 1: The eutrophication water body self-purification restoration method described in this embodiment consists of the following steps:

[0028] 1. In the eutrophication water, mix ozone gas according to the concentration of 5mg / L.

[0029] 2. The gas-liquid mixture composed of eutrophic water and ozone is irradiated with ultraviolet rays. Intensity of ultraviolet irradiation is based on the volume of the inner cavity of the excitation reaction chamber 7, and a 30-watt ultraviolet lamp tube is installed every 10 liters.

[0030] Wherein, the residence time in the excitation reaction chamber 7 is controlled at 120 seconds. Simultaneously agitate the bottom sludge to allow it to rise and re-sediment.

Embodiment 2

[0031] Embodiment 2: The eutrophication water body self-purification restoration method described in this embodiment consists of the following steps:

[0032] 1. In the eutrophication water, mix ozone gas at a concentration of 45mg / L.

[0033] 2. The gas-liquid mixture composed of eutrophic water and ozone is irradiated with ultraviolet rays. Intensity of ultraviolet irradiation is based on the volume of the inner cavity of the excitation reaction chamber 7, and a 40-watt ultraviolet lamp tube is installed every 30 liters.

[0034] Wherein, the residence time in the excitation reaction chamber 7 is controlled at 20 seconds. Simultaneously agitate the bottom sludge to allow it to rise and re-sediment.

Embodiment 3

[0035] Embodiment 3: This embodiment describes a self-purifying restoration device for eutrophic water body, its structure is as follows figure 1 shown. This embodiment includes a water intake pipe 2, an ozone mixer 3, a turbulent flow mixer 6, an excitation reaction chamber 7, and a return pipe 9, which are sequentially connected in series by corresponding pipelines. In this embodiment, the ozone mixer 3 is made up of a water pump 31 and an ejector 32; the ozone gas production port of the ozone generator 4 is connected with the air inlet of the ejector 32, and a check valve 5 is installed in the middle to prevent the water from pouring into the ozone generator 4. The excitation reaction chamber 7 is equipped with an ultraviolet light source 8, and the ultraviolet light source is an ultraviolet lamp with a wavelength of 200 to 280 nm as a light source; in the present embodiment, the volume of the inner cavity of the excitation reaction chamber 7 is 400 liters, and 40 A 30-wa...

Abstract

The invention provides the eutrophication water self-purification renovation method, comprising the following steps: 1. add the ozone gas into the eutrophication water. 2. Ultraviolet irradiates the solution-air mixture composed by eutrophication water and ozone. The invention also provides the eutrophication water self-purification renovation device, comprising ship hull. On the ship hull there is water pipe, ozone agitator, agitation catalyst case, and reflux pipe, which are connected in series by pipes. The inlet port of ozone agitator is connected with outlet of ozone source, and in the middle of them there is back valve. In the agitation catalyst case there is ultraviolet light source. The invention has the advantages of fast recovering the water self-purification ability, improving impact resistance, extending rebound time and inhibiting eutrophication water quality.

Description

technical field [0001] The invention relates to a method for self-purification and repair of eutrophic water body and a repair device. Background technique [0002] Eutrophic water refers to water bodies such as rivers, lakes, and landscape water. After being polluted, a large number of algae will be formed, and in severe cases, algal blooms will break out. It contains a very complex microbial population, including harmful algae and plankton, as well as beneficial aerobic bacteria, anaerobic bacteria and facultative bacteria. [0003] At present, there are mainly the following methods for treating eutrophic water bodies at home and abroad: aeration and oxygenation method, filtration method, and chemical dosing method, but they all have many shortcomings, such as: [0004] Although the aeration and oxygenation method can provide dissolved oxygen in the water body and strengthen the self-purification ability of the water body, it cannot effectively remove nitrogen and phospho...
