Embodiment Construction

[0014] Now the specific embodiment of the present invention is described (taking Microcystis aeruginosa as example):

[0015] (1), the cultivation of Microcystis aeruginosa, inoculate the pure algae species of Microcystis aeruginosa purchased in "BG-11 medium", the inoculation amount is 10%, at 28 ℃, the light cycle is 12:12 (h) cultured in a constant temperature incubator. After the culture grows to the logarithmic growth phase, when the color of the culture medium turns green obviously by visual inspection, it can be used as an experimental sample and is ready for use;

[0016] (2) Pour the above-mentioned algae solution cultivated to the logarithmic growth phase into a sterilized petri dish, place it on an electron beam radiation device in an open environment, and perform electron beam radiation treatment. The electron beam irradiation device has an energy of 1.8MeV, a beam current of 1.0mA, and a radiation dose of 1kGy. The radiation doses used in the experiment were 1kG...

Abstract

The invention relates to a method for efficiently controlling, eliminating and inactivating blue algae, particularly microcystis aeruginosa in the source water, the water in the water plant, the scenic lake water and the river water by irradiating electron beams, belonging to the field of the water pollution control, the water treatment technology and the environmental protection. The test proves that the electron beams are irradiated by an electronic irradiating device which has the electron beam irradiating energy of 1.8 MeV and the electron beam current of 1.0 mA at the room temperature of 25 DEG C and the atmospheric pressure of 1013.2 hpa, and the optimum dosage of the electron beams irradiated for eliminating or inactivating the microcystis aeruginosa is 4-5 kGy.

Description

Technical field: [0001] The invention relates to an electron beam irradiation treatment method for controlling and inactivating Microcystis aeruginosa in a water body, belonging to the fields of water pollution control, water treatment technology and environmental protection. Background technique [0002] Cyanobacterial blooms and their toxins are the focus of water eutrophication pollution hazards, and Microcystis aerugiosa occupies a major proportion in the number of individuals and the secretion of algal toxins. Conventional water treatment processes such as coagulation, sedimentation, filtration, and chlorination in tap water treatment processes cannot effectively remove algal toxins in water. Physical methods such as air flotation, membrane filtration, and activated carbon adsorption can only transfer MCs from one medium to another. A medium, general chemical oxidation methods such as chlorination and potassium permanganate oxidation have the risk of forming three disin...
