Embodiment 1

[0027] A method for preparing seaweed water-soluble fertilizer with fresh kelp blanching wastewater, specifically comprising the following steps:

[0028] 1. Preparation of concentrated seaweed liquid

[0029] The fresh kelp blanching waste water is transported to the raw material water tank through the water pump, and then the raw material water is transported from the raw material water tank to the bag filter for filtration through the water pump. The mesh number of the filter screen is 80-120 mesh, and the impurities in the raw material water are filtered out. , the filtrate is pumped into the filtrate tank. The filtrate is pumped to a three-effect falling film evaporator for concentration, the concentration ratio is 30 times, and the specific gravity of the concentrate reaches 1.03. The concentrated liquid is pumped into a high-speed centrifuge to filter out the high-temperature salt (mainly sodium chloride) and other impurities in the concentrated liquid. The centrifugal...

Embodiment 2

[0039] A method for preparing seaweed water-soluble fertilizer with fresh kelp blanching wastewater, specifically comprising the following steps:

[0040] 1. Preparation of concentrated seaweed liquid

[0041] The fresh kelp blanching waste water is transported to the raw material water tank through the water pump, and then the raw material water is transported from the raw material water tank to the bag filter for filtration through the water pump. The mesh number of the filter screen is 80-120 mesh, and the impurities in the raw material water are filtered out. , the filtrate is pumped into the filtrate tank. The filtrate is pumped to a three-effect falling film evaporator for concentration, the concentration ratio is 32 times, and the specific gravity of the concentrate reaches 1.03. The concentrated liquid is pumped into a high-speed centrifuge to filter out the high-temperature salt (mainly sodium chloride) and other impurities in the concentrated liquid. The centrifugal...

Embodiment 3

[0051] A method for preparing seaweed water-soluble fertilizer with fresh kelp blanching wastewater, specifically comprising the following steps:

[0052] 1. Preparation of concentrated seaweed liquid

[0053] The fresh kelp blanching waste water is transported to the raw material water tank through the water pump, and then the raw material water is transported from the raw material water tank to the bag filter for filtration through the water pump. The mesh number of the filter screen is 80-120 mesh, and the impurities in the raw material water are filtered out. , the filtrate is pumped into the filtrate tank. The filtrate is pumped to a three-effect falling film evaporator for concentration, the concentration ratio is 38 times, and the specific gravity of the concentrate reaches 1.04. The concentrated liquid is pumped into a high-speed centrifuge to filter out the high-temperature salt (mainly sodium chloride) and other impurities in the concentrated liquid. The centrifugal...

Abstract

The invention relates to seaweed water-soluble fertilizer and a preparation method thereof and solves the problems that existing methods cannot comprehensively utilize fresh kelp blanching waste water and are complex in extraction processing and high in processing cost. The seaweed water-soluble fertilizer comprises one or more of fucoidan, mannitol, major elements, medium elements, trace elements, humic acid and amino acid. The preparation method is applicable to kelp blanching waste water processing and seaweed water-soluble fertilizer preparing. The seaweed water-soluble fertilizer includes organic seaweed water-soluble fertilizer, seaweed water-soluble fertilizer containing humic acid, seaweed water-soluble fertilizer containing amino acid, seaweed water-soluble fertilizer containing major elements, seaweed water-soluble fertilizer containing medium elements and seaweed water-soluble fertilizer containing trace elements.

Description

technical field [0001] The invention belongs to the fields of environmental protection and seaweed fertilizer, and in particular relates to a water-soluble seaweed fertilizer and a preparation method thereof. Background technique [0002] The processing and production of salted kelp in my country is mainly concentrated in coastal areas, such as Shandong, Fujian, and Liaoning. Fresh kelp is blanched in hot water at 80-90°C, and then mixed with salt for dehydration to obtain salted kelp. During the processing of salted kelp, a large amount of wastewater is generated, and these wastewaters are generally discharged directly into the sea without any treatment. [0003] After a lot of research and analysis, it was found that in addition to some suspended solids, nitrates, nitrites and other environmental pollutants in fresh kelp blanching wastewater, most of the ingredients are iodine, fucoidan, mannitol, fucoidan, and fucoxanthin. Wait. Therefore, if the fresh kelp blanching w...
