Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a method for resource utilization of aquatic plants. The raw material of the method is the waste of aquatic plants, which not only solves the problem of common waste of aquatic plants such as landfill, on-site stacking or incineration, etc. The environmental problems caused by the means of waste disposal have also enriched the resource utilization of aquatic plants, giving full play to the value of aquatic plants

Embodiment 1

[0049] A resource utilization method for aquatic plants, comprising the following steps:

[0050] 1) The production process of plant feed:

[0051] 1-1) Raw material pretreatment: mechanically crushing the aquatic plant waste to a particle size of ≤20 mm to obtain the first crushed raw material;

[0052] 1-2) Feed production: transport the first crushed raw material to the treatment tank, and use ammoniation to process the first crushed raw material to obtain vegetable feed; said ammoniated refers to the first crushed raw material in step 1-1). Adding urea to the crushed raw materials makes the cellulose, hemicellulose and lignin separate, the structure is looser, and the utilization rate of aquatic plant straw is improved. Specific operation: now pure urea and water are prepared in a ratio of 1:10 by mass ratio to prepare an aqueous urea solution, and then the aqueous solution of urea and the first crushed raw material in step 1-1) are mixed by a ratio of 1:5 by mass, and th...

Embodiment 2

[0071]A resource utilization method for aquatic plants, comprising the following steps:

[0072] 1) The production process of plant feed:

[0073] 1-1) Raw material pretreatment: mechanically crushing the aquatic plant waste to a particle size of ≤20 mm to obtain the first crushed raw material;

[0074] 1-2) Feed production: transport the first crushed raw material to the processing tank, and use silage to process the first crushed raw material to obtain vegetable feed; the silage refers to the use of microbial fermentation to generate an acidic environment and inhibit microbial fermentation. The reproduction of is currently the method with the largest processing capacity. Specific operation: first use a watering can to spray 15kg of water on every 100kg of the first crushed raw material in step 1-1), then add 5kg of urea to every 100kg of the first crushed raw material, stir evenly, compact and seal in the silage tank , silage can be used for feeding after 40-60 days;

Embodiment 3

[0089] A resource utilization method for aquatic plants, comprising the following steps:

[0090] 1) The production process of plant feed:

[0091] 1-1) Raw material pretreatment: mechanically crushing the aquatic plant waste to a particle size of ≤20 mm to obtain the first crushed raw material;

[0092] 1-2) Feed production: the first crushed raw material is transported to the treatment tank, and the first crushed raw material is processed by a micronized production method to obtain vegetable feed; the micronized is in step 1-1) High-efficiency active fermentation bacteria are added to the first crushed raw material to accelerate the decomposition and conversion of cellulose, hemicellulose and lignin by increasing the number of microorganisms, and convert the first crushed raw material into moist, swollen and soft feed.

[0093] 1-3) feeding the plant feed obtained in step 1-2) to livestock and poultry; the excrement of livestock and poultry will be used in the production pr...

Abstract

The invention discloses an aquatic plant recycling method. The method comprises the following steps: 1, producing a botanical feed: 1-1) preprocessing a raw material; 1-2) producing a feed; and 1-3) nursing livestock and poultry; 2, producing biomass energy: 2-1) carrying out retting pretreatment; 2-2) mixing raw materials; 2-3) carrying out dry anaerobic fermentation; and 2-4) carrying out biogas comprehensive utilization; and 3, producing a high-efficiency multi-bacterial composite ecologic fertilizer: 3-1) preparing raw materials; 3-2) mixing and proportioning the raw materials; 3-3) carrying out high-temperature aerobic composting; 3-4) carrying out medium-temperature aerobic composting; and 3-5) mechanically granulating the obtained product, and packaging the granulated product. Aquatic plant wastes are adopted as the raw material, so the environment problems brought by landfill, onsite stacking or burning and other common aquatic plant waste disposing means are solved, the aquatic plant recycling mode is enriched, and values of aquatic plants are fully shown.

Description

technical field [0001] The invention relates to a resource utilization method of aquatic plants, which belongs to the technical field of environmental protection. Background technique [0002] At present, the surface water environment in our country is seriously polluted, which has brought many hazards to the water environment quality, water ecological safety and drinking water safety. The protection of water resources, water pollution control and water ecological restoration of urban inland rivers and related rivers are imminent. The technology of using aquatic plants to restore water bodies in situ is gradually being applied to water restoration projects. [0003] In order to avoid the decomposition and decay of aquatic plant residues, consume dissolved oxygen in water, and cause secondary pollution of water bodies, it is necessary to harvest them in time, which will generate a large amount of aquatic plant waste. The commonly used methods of disposal of aquatic plant was...
