Technical Field
The invention relates to the technical field of enteromorpha prevention and control, in particular to an offshore enteromorpha disposal method based on a glue enveloping technology.
Background
In 2008, about thousands of tons of enteromorpha are gathered on the Qingdao along the bank in 6-7 months every year, and the flaky enteromorpha floats and gathers on the sea surface to form green tide, block a channel and influence shipping and fishing boat operation; a large amount of enteromorpha deposits on the coast, and the rotten odor is deteriorated, so that the marine ecosystem is damaged; meanwhile, the water quality is deteriorated, the production and development of coastal fishery such as sea cucumbers, abalones and the like are seriously threatened, and coastal landscapes are also damaged, so that the tourism industry suffers great loss.
After green tide of enteromorpha occurs, government departments organize to develop 'enteromorpha war' for a plurality of times, and make important contribution to keeping coastal cleanness and normal resident life. Currently, main disposal methods for enteromorpha are offshore sea surface salvage and shore side collection, and then the enteromorpha is transported to a sea area behind a Qingdao for burying treatment. Due to the fact that the enteromorpha is large in quantity and quick in time, and the enteromorpha has the characteristic of growing while moving, if the enteromorpha is subjected to general traditional shoreside fishing and collection, the enteromorpha cannot be thoroughly treated. Therefore, an emergency disposal method before large-scale outbreak of enteromorpha is urgently needed.

The invention is implemented according to the following technical scheme:
an offshore enteromorpha disposal method based on a glue enveloping technology comprises offshore fishing, crushing and fermenting of enteromorpha and glue enveloping of enteromorpha; after the enteromorpha is salvaged and loaded on the salvage ship, the enteromorpha is smashed by a smashing machine and then fermented in a biological reaction chamber, fermented enteromorpha liquid is enveloped by a carrier, spheroids with high shape-preserving rate and density higher than that of seawater are prepared by a granulating device, and the spheroids are directly conveyed to the seabed.
Further, seawater is added in the enteromorpha crushing process for crushing.
Further, the fermentation treatment comprises inoculating baker's yeast and bacillus subtilis in the crushed enteromorpha liquid, then uniformly stirring, and fermenting at room temperature;
further, the carrier for enveloping the fermented enteromorpha liquid is yellow soil with higher viscosity, and after the yellow soil and the enteromorpha slurry are mixed and stirred uniformly, the weight ratio of the enteromorpha slurry to the carrier yellow soil is 4: 1-3: 1, preparing spheroids with high shape-keeping rate, wherein the size of the spherical particles is 2.0cm-2.5 cm.
Furthermore, the addition amount of the seawater is 2-5 times of the volume of the enteromorpha during the crushing of the enteromorpha.
Further, the particle size of the crushed enteromorpha is 1-10 mm.
Further, the inoculation amount of the bread yeast in the enteromorpha fermentation process is 0.01-0.05% of the weight of enteromorpha slurry, and the inoculation amount of the bacillus subtilis is 0.02-0.04% of the weight of the enteromorpha slurry; the fermentation time is 5-12 h.
Compared with the prior art, the invention has the beneficial effects that:
1) the method for treating the enteromorpha only needs a plurality of ships with high mechanization level to operate, and the millennia is not needed to salvage, so that a great amount of manpower, material resources and financial resources can be saved.
2) The enteromorpha is actively tracked and early warned offshore, the passive waiting until the enteromorpha outbreak and then emergency treatment are not needed, the passive is changed into the active, and the enteromorpha is disposed before the enteromorpha disaster.
3) Offshore disposal can implement ecological application to change waste into treasure, and enteromorpha is changed into food of sea organisms such as sea cucumber, shellfish, cephalopods, fishes and the like, thereby generating obvious ecological benefit.
4) The offshore disposal can lead the enteromorpha to return to the sea by active glue body and feed marine organisms, and the material is obtained from the sea and used for the sea. Saves a large amount of stacked land resources for burying enteromorpha.
