Embodiment Construction

[0033] Examples of the present invention are described below.

[0034] 1. Preparation of cyanobacteria culture material

[0035] Take 30kg of blue-green algae mud, first hydrothermal treatment (121 ℃ and 1.2MPa) for 30 minutes, to destroy the blue-green algae cells. After cooling, add 20% bran by weight and mix well. Then inoculate about 5% of the mixed fermentation broth and ferment naturally for 2 days.

[0036] 2. Preparation of fly eggs

[0037] Get about 10g of pure Chrysocephala brucella ovum from the breeding cage of the kind of fly for hatching larvae (fly maggots).

[0038] 3. Cultivation of fly maggots with cyanobacteria compost

[0039] The prepared cyanobacteria culture material is evenly placed in 2 culture trays with a groove around it, the length of the plate is 70cm, the width is 50cm, the depth is 8cm, and the culture material is filled with a thickness of 5cm. According to the standard of inoculating 0.3 grams of eggs per kilogram of material (equivalent...

Abstract

The invention provides a method for biologically treating and transforming blue algae by using insect larvae, and belongs to the technical field of resource environments. The method comprises the following steps of: after the fished blue algae serous fluid or the dehydrated blue algae mud is hydro-thermally treated, adding a little amount of bran into the blue algae serous fluid or the blue algae mud, and pre-fermenting the mixture for 2 days to prepare a culture material for fly larvae, wherein the thickness of the culture material in a culture tray is 5 to 10 centimeters; inoculating 0.3 gram of fly eggs to the surface of each kilogram of culture material, wherein the point-sowing density is 3 to 5 places per square meter; and placing the culture tray in a room with good ventilation and weak rays, culturing the fly eggs for 3 to 5 days, and harvesting the fly larvae serving as feed protein after the fly larvae is mature. The residue is smell-less and loose, greatly reduces the moisture, has rich nutrient, and can be directly used as a biological organic fertilizer. The method for treating the blue algae is efficient and quick and has high economic benefit.

Description

1. Technical field [0001] The invention relates to a method for biologically treating and transforming cyanobacteria with insect larvae so as to obtain complete resource utilization of the cyanobacteria, and belongs to the technical field of resources and environment. 2. Background technology [0002] With the discharge of industrial wastewater and domestic sewage, there are also some agricultural activities (such as large-scale fertilization), resulting in a large amount of nutrient salts entering the lake, resulting in increasingly serious eutrophication of the water body, thereby inducing large-scale explosive reproduction of cyanobacteria (algae bloom phenomenon) ). Blue-green algae blooms will deteriorate the sensory properties such as water color and transparency. When blue-green algae multiply, they will emit a fishy smell, and when they die and rot, they will emit a foul smell. The large-scale reproduction of cyanobacteria and the decomposition of dead algae will al...
