[0003] Patent Nos. CN101418315, CN102876727, and CN101665807 use Enteromorpha to ferment biogas, but the fermentation time is long, time-consuming and energy-consuming, and there is no effective utilization method for biogas residues, and the utilization value of Enteromorpha cannot be fully developed. Patent Nos. CN103772073, CN103772012A, CN103352016 use aerobic fermentation to make a kind of organic fertilizer that can use crops and soil, but the single product obtained by relatively complex treatment of Enteromorpha cannot fully exert the potential of Enteromorpha
Patent Nos. CN103583683A and CN103040075 propose a method of utilizing Enteromorpha to produce preservatives, but the utilization method is single and the utilization is not thorough
In terms of academic papers, "Research on the Biogas Potential of Fresh Enteromorpha Fermentation at Room Temperature", "Effects of Particle Size and Several Pretreatment Methods on the Biogas Production of Enteromorpha Anaerobic Fermentation", "Different Pretreatment and Fermentation Conditions on the Biogas Production of Enteromorpha Yield Impact" and so on have proved that Enteromorpha has excellent potential for biogas production, but the pretreatment in its process is completely prepared for anaerobic fermentation, and the product cannot be obtained, nor can the potential value be developed from it, and there is no impact on biogas production. The slag provides a valuable utilization method, which cannot achieve the purpose of comprehensive development

Embodiment 1

[0019] (1) Rinse 10 tons of fresh Enteromorpha with a water content of 85% for 3 times with fresh water to remove some impurities such as salt and sediment in Enteromorpha;

[0020] (2) Carry out pretreatment to Enteromorpha, cut Enteromorpha into 5 cm strips of Enteromorpha;

[0021] (3) Put Enteromorpha into the aerobic fermentation equipment, add fresh water to make the total solid content in the fermentation equipment 5%, add the inoculum (EM-W bacterial agent), and the inoculum amount is 2%. Place it in a fermentation bed for constant temperature fermentation, and the culture temperature is 35°C.

[0022] (4) Enteromorpha was fermented for 10 days and filtered, and the filtrate was centrifuged to separate the supernatant and Enteromorpha residue. After the supernatant is packaged, it is used as a fruit liquid preservative.

[0023] (5) Using the fermentation residue separated in step (4) as a raw material for anaerobic biogas fermentation. Put the enteromorpha residue ...

Embodiment 2

[0027] (1) Pretreatment is carried out, and 10 tons of semi-dried Enteromorpha enteromorpha with a water content of 40% are crushed to a particle size of 5 mm;

[0028] (2) Put Enteromorpha into the aerobic fermentation equipment, add water to make the total solid content in the fermentation equipment 0.5%, add the inoculum (special fermentation bacteria agent), the inoculation amount is 0.2%. Place it in a fermentation bed for constant temperature fermentation, and the culture temperature is 25°C.

[0029] (3) Enteromorpha was fermented for 6 days and filtered, and the filtrate was centrifuged to separate the supernatant and Enteromorpha residue. After the supernatant is packaged, it is used as a fruit liquid preservative.

[0030] (4) Anaerobic fermentation is carried out using the fermentation residue separated in step (3) as a raw material. Put the enteromorpha residue obtained by centrifugation into an anaerobic fermentation tank, add biogas slurry, add water to the ana...

Embodiment 3

[0034] (1) Rinse 10 tons of dry Enteromorpha with water to remove some impurities such as salt and sediment in Enteromorpha;

[0035] (2) Pretreating the Enteromorpha, crushing the Enteromorpha until the particle size is 10 mm;

[0036] (3) Put Enteromorpha into the aerobic fermentation equipment, add water so that the total solid content in the fermentation device is 2%, add the inoculum (Bacillus subtilis, Pseudoalteromonas, Bacillus pumilus, Bacillus licheniformis, green Trichoderma complex agent), the inoculation amount is 1%. Place it in a fermentation bed for constant temperature fermentation, and the culture temperature is 30°C.

Abstract

The invention relates to the field of biomass resource utilization, particularly a comprehensive utilization method for enteromorpha prolifera. The invention aims to provide the high-additional-value comprehensive utilization method which is completely utilized and free of waste, for enteromorpha prolifera. According to the characteristics of the enteromorpha prolifera, flow line type production is realized by using an enteromorpha prolifera production fruit preservative, biogas and an organic fertilizer through aerobic fermentation and anaerobic fermentation. The comprehensive utilization method has an outstanding utilization value of completely and sufficiently utilizing the enteromorpha prolifera resource, so that a marine ecological problem caused by large-scale bred enteromorpha prolifera is eliminated, the fruit preservative, the biogas and the organic fertilizer which have an extremely high commercial value are developed. The comprehensive utilization method has a sufficient commercial development value.

Description

technical field [0001] The invention relates to the field of utilization of biomass resources, in particular to a comprehensive utilization method of enteromorpha. Background technique [0002] Enteromorpha, also known as moss strips, green seaweed, etc., is a widely distributed large seaweed. Enteromorpha is rich in nutrients, with protein content of 9%-14%, fat content of 0.9%-2%, crude fiber of 8%-12%, and ash content of 18%-25%. In addition, the reproductive capacity of Enteromorpha is extremely strong. Since 2007, there have been many "green tides" of Enteromorpha in the sea area of ​​​​Shandong, China. smelly, pollute the environment, and these gathered enteromorpha will block the waterway, seriously threatening the development of coastal fishery and tourism. In 2008, the green tide covered an area of ​​more than 2×10 km2 in the sea area of ​​Qingdao, and 8×10 7kg of Enteromorpha was salvaged. In recent years, scientists have actively studied the application value ...
