Problems solved by technology

Since 2008, millions of tons of Enteromorpha have gathered along the coast of the Shandong Peninsula from June to July every year. Pieces of Enteromorpha float and gather on the sea surface to form a green tide, blocking waterways and affecting shipping and fishing operations; a large amount of Enteromorpha deposits on the coast At the same time, the deterioration of water quality seriously threatens the production of sea cucumbers, abalones, prawns, fish, etc., and the coastal landscape is also damaged, causing huge losses to its tourism industry.
These traditional methods of disposal of Enteromorpha have not fundamentally solved the problem of Enteromorpha, and there are deficiencies and serious problems such as low collection efficiency, high transportation costs, and secondary pollution to the terrestrial environment.

Embodiment 1

[0019] Install salvage devices, conveyor belts, shredders, beaters, on-board fuel-fired steam boilers, steam reaction tanks and other facilities and equipment on the enteromorpha salvage ship to realize independent operation of the vessel platform. figure 1 shown.

[0020] In late June 2016, the satellite cloud image observed that Enteromorpha moved northward and entered the coastal waters of Rizhao City, Shandong Province. When Enteromorpha gathered in the southeast waters of Huangdao District, Qingdao City and formed strips, the salvage ship went out to sea and arrived at Enteromorpha. In the front line, tracking and salvage operations are carried out. The fresh Enteromorpha salvaged from the sea is drained on the conveyor belt, chopped by a chopper (0.5-2cm), and seawater is added according to the ratio of Enteromorpha: seawater mass ratio of 1:2-4, and the Enteromorpha is made by grinding with a beater Slurry (the particle size of Enteromorpha after grinding reaches 20-20...

Embodiment 2

[0022] Denaturation Effect of Maturation Process on Enteromorpha Protein

[0023] Get the Enteromorpha slurry before and after denaturation in Example 1 and carry out microscopic observation, it can be seen that the Enteromorpha particle size ranges from 75 to 850 μm after being ground by a beater, and the particle size is 20 to 200 mesh ( figure 2 ); the microscopic observation of the undenatured Enteromorpha showed that the cells of the Enteromorpha debris particles were arranged neatly and densely after plasmatization, and the chloroplasts were bright, and they were still in the state of active vegetative cells. The gap increased, the color of chloroplasts deepened and the cleavage was scattered in the cells, showing signs of apoptosis ( image 3 ). Take 1ml of the heat-denatured slurry, put it into the PES culture medium after autoclaving, and cultivate it in a light incubator. 2 .s), the light cycle is 12L:12D, after 10 to 15 days of light culture, no Enteromorpha bran...

Abstract

The invention relates to a ripening and degenerating treatment and utilization method of alive enteromorpha prolifera in offshore sea areas, and belongs to the technical field of environmental protection and biological processing. According to the method, before the enteromorpha prolifera enters near shores, the enteromorpha prolifera floating on the sea surface are collected, pulped, ripened anddegenerated into semi-fluid algin, and the semi-fluid algin is directly discharged into the sea areas through a delivery pipe; the semi-fluid algin serves as a good bait for various marine organisms to achieve resource utilization. By the method, offshore on-site treatment of the enteromorpha prolifera can be realized, and food sources convenient to absorb and utilize can be provided for the marine organisms; gametes of the enteromorpha prolifera can be efficiently killed due to the thermotropy, the reproductive effect of the enteromorpha prolifera can be efficiently inhibited, the proliferation speed of the enteromorpha prolifera is decreased when the enteromorpha prolifera drifts near the shores, propagation control and limited expansion of the enteromorpha prolifera in the offshore seaareas are benefited, and good economic, social and ecological benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and biological processing, and in particular relates to a treatment and utilization method for ripening and denaturation of fresh and live Enteromorpha in offshore sea areas. Background technique [0002] Enteromorpha is a natural wild green algae in coastal beaches. Relevant studies have shown that Enteromorpha has multiple reproductive modes, including sexual reproduction, asexual reproduction, and vegetative reproduction (Lin, 2008). In this way, algae are continuously expanded (Liang Zongying et al., 2008), and the release of a large number of germ cells has imported more new individuals into the sea area. Enteromorpha is a high-protein, low-fat, and rich in trace elements algae, which can be used as a feed source for a variety of marine organisms. It is a good biomass with good potential for resource utilization (Lin Yingting, 2015), But a large number of growth and regional...
