Embodiment 1

[0023] Embodiment 1 prepares mineral algae decomposition accelerator

[0024] Weigh 85g of 2500-3000mesh muscovite powder, 10g of 2500-3000mesh amazonite and 5g of limestone, add 500g of hydrogen peroxide with a concentration of 30v% at 85°C, stir thoroughly for 4-8 hours, and then add 4.5g of NaCl in sequence , FeCl 3 2.0g and MgCl 2 2.5g (NaCl, FeCl 3 and MgCl 2 Both need to be configured as an aqueous solution with a concentration of 10wt% before adding). Stir again for 4-8 hours, then dry and grind to become the finished product of mineral algae decomposition accelerator.

Embodiment 2

[0025] Example 2 Application of a landscape lake in Fengtai, Beijing

[0026] Investigate the method of the present invention to the algae treatment effect of a landscape lake in Fengtai District, Beijing. The characteristics of the lake are that the source of replenishment water is regenerated water, the amount of replenishment water meets the amount of evaporative seepage water, there is no ecological water exchange amount, no sewage outlet source enters the lake, and the treatment method is continuous treatment throughout the year.

[0027] The dosing method is as follows: fix the dispensing barrel and the sprayer on a speedboat with a power of not less than 10 3 Add 400L of clear water to the PE dispensing cartridge, weigh 2.5kg of mineral algae decomposing agent, and 5kg of compound microbial strains, and stir evenly. Then use a 5.5-horsepower high-pressure sprayer (lift 22 meters) to spray the mixed medicine on the water surface at an angle of 40 degrees (the angle betw...

Embodiment 3

[0035] Example 3 Application of algae control in a certain river in Beijing

[0036] The total length of this experimental section is about 4.2 kilometers, and the water surface area is about 84,000 square meters. The characteristics of this river course are: there is continuous water coming from the upper reaches, and a small amount of sewage flows into it. The treatment method is from July to November every year. Adopt the dosing method described in embodiment 2, the dosage of composite microbial strains in 2013 and 2014 is 3.0g / m 3 , the dosage of mineral algae decomposer is 1.5g / m 3 . Before treatment, algal growth was serious in the water quality of the water body. After four weeks of treatment, the degree of eutrophication in the water body was greatly reduced.

Abstract

The invention discloses a method for treating algae-containing water bodies by utilizing a mineral algae decomposition accelerator with a compound microorganism in an assistant manner. The method comprises the step of adding the mineral algae decomposition accelerator into algae-containing water bodies while adding the compound microorganism, wherein the mineral algae decomposition accelerator is white mica which adsorbs Na, F and Mg ions; the dosage of the compound microorganism is 0.5-5 g / m<3>; the dosage of the mineral algae decomposition accelerator is 0.1-3 g / m<3>. The method is suitable for the natural or artificial water bodies such as algae-containing lakes, reservoirs and rivers, and can be used for greatly improving the elimination and degradation speeds of the algae and eliminating the influence of algae explosion on the water environment in a short time. The method is simple to operate, low in operation management expense and rapid in algae elimination effect; the mineral algae decomposition accelerator and the compound microorganism do not cause secondary pollution to the water bodies, so that the method belongs to an environment-friendly technology.

Description

technical field [0001] The invention relates to a method for treating algae-containing water by microorganisms, in particular to a method for using a mineral algae decomposition accelerator to assist compound microorganisms to treat algae-containing water. Background technique [0002] Cyanobacteria are prokaryotic organisms, also known as blue-green algae. Most of the blue-green algae have gelatinous coats outside their cell walls, and blue-green algae are the simplest and most primitive one. In some nutrient-rich water bodies, cyanobacteria often multiply in large numbers in summer, and form a layer of blue-green and fishy-smelling floating foam on the water surface, which is called a bloom. Algal blooms can cause deterioration of water quality, and in severe cases deplete the oxygen in the water and cause the death of fish. Some species of cyanobacteria (such as Microcystis) also produce microcystins, which are directly toxic to fish, humans and animals. [0003] The co...
