Problems solved by technology

[0007] The above patents are all for the purpose of supplementing minerals and trace elements. Among them, the treatment process of the invention patent CN103082372A uses fiber filtration, ultrafiltration, reverse osmosis, evaporation and concentration to obtain mineral concentrates. The process is complicated and difficult to operate, resulting in energy waste; Invention patent CN9210636.4 removes chloride ions by electrolysis and then evaporates and concentrates, which consumes a lot of energy and causes secondary pollution; Invention patent CN105884086A is relatively simple in the early stage and causes the burden of the later nanofiltration process, and does not deepen the treatment of excessive heavy metal ions and harmful substances in seawater. substances, resulting in poor product quality

Embodiment 1

[0038] Use brine as raw material to produce mineral concentrates rich in trace elements, such as figure 1 shown, including the following steps:

[0039] 1) When the brine is pumped into the first-stage coagulation tank, the coagulant A+B is mixed through the mixer, and the addition amount is 20mg / L. Most of the heavy metals were removed by coagulation and sedimentation. Coagulant A+B is polyferric silicate (PFSI) + polyaluminum ferric chloride (PAFC). The weight percentage of coagulant added is: polyferric silicate accounts for 40%, and polyaluminum ferric chloride accounts for 60%.

[0040] 2) The brine after coagulation and settlement is injected into the three-stage filtration system with the pump, and the pore size of the filter element decreases step by step to less than 0.01µm, and the maximum operating pressure is 0.3Mpa, and then passes through the pre-purification device to remove part of the organic matter and heavy metal ions in the seawater. The operating pressur...

Embodiment 2

[0047] The difference with Example 1 is that the amount of coagulant A+B added to the mixer in this Example 2 is 30 mg / L, and the maximum operating pressure of the nanofiltration membrane in step 3) is 3.5 MPa. When TDS (dissolved The total amount of sexual solids) reached 215000mg / L

[0048] , the concentrated solution can be pumped out. After testing, the main ion concentration in the mineral concentrated solution is Ca 2+ 150mg / L, Mg 2+ 31000mg / L, K + 3000mg / L, Cl - 12000mg / L, other heavy metal ions lead ions ≤0.005 mg / L, cadmium ions ≤0.01 mg / L, arsenic ions ≤0.05 mg / L, NO 2- The content is effectively reduced to 0.005mg / L.

Embodiment 3

[0050] The difference from Example 1 is that the amount of coagulant A+B added to the flow mixer in Example 2 is 40 mg / L, and the maximum operating pressure of the nanofiltration membrane in step 3) is 3.7 MPa. When TDS (dissolved When the total amount of sexual solids) reaches 230000mg / L, the concentrated solution can be pumped out. After testing, the main ion concentration in the mineral concentrated solution is Ca 2+ 200mg / L, Mg 2+ 35000mg / L, K + 3500mg / L, Cl - 8000mg / L, other heavy metal ions lead ions ≤0.005 mg / L, cadmium ions ≤0.01 mg / L, arsenic ions ≤0.05mg / L, NO 2- The content is effectively reduced to 0.005mg / L. Coagulant A+B is polyferric silicate (PFSI) + polyaluminum ferric chloride (PAFC). The weight percentage of coagulant added is: polyferric silicate accounts for 40%, and polyaluminum ferric chloride accounts for 60%.

Abstract

The invention provides a mineral matter concentrate rich in trace elements, and a preparation method and an application thereof. The concentrate is prepared from brine obtained after concentrating seawater, the total content of soluble solids in the concentrate is 200,000-230,000 mg / L, the concentration of Ca<2+> in the concentrate is 100-200 mg / L, the concentration of Mg<2+> in the concentrate is 28000-35000 mg / L, the concentration of K<+> in the concentrate is 2500-3500 mg / L, and the concentration of Cl<-> in the concentrate is 8000-15000 mg / L. Coagulation sedimentation, filtration and pre-purification, nanofiltration and deep purification processes are carried out to remove a large number of monovalent salts in the seawater and heavy metals harmful to human bodies and obtain the mineral matter concentrate reserving beneficial minerals and trace elements needed by human bodies; and the concentrate has the advantages of supplementation of trace elements missing in the human bodies, deep removal of wastes and toxins from the human bodies, purification of blood, and stimulation of the regeneration and self-repairing ability of cells, and has the efficacy of promoting human body metabolism, enhancing the systemic immunity and restoring youthfulness.

Description

[0001] Technical field: [0002] The invention relates to a mineral concentrate rich in trace elements, a preparation method and application thereof. [0003] Background technique: [0004] Minerals and trace elements are necessary for the human body. 600 experts have warned that 90% of diseases are caused by the lack of trace elements. Dr. Lanus Pauling, a two-time Nobel laureate, said: "All human diseases originate from Mineral element imbalance", therefore, too much or too little minerals and trace elements in the human body will endanger human health and even life. The mineral concentrate rich in trace elements produced by the present invention contains a variety of minerals and trace elements needed by the human body, and has various pharmacological and physiological functions, such as calcium supporting and protecting bones and teeth, calcium in blood Participate in the blood coagulation process, maintain a certain ratio of calcium and potassium, sodium, and magnesium io...
