preparation example Construction
[0035] The invention provides a method for preparing physiological deep seawater, comprising the following steps:
[0036] S1. Use polypropylene melt-blown PP cotton with a pore size of 5mm to initially filter the original seawater, and then use polypropylene melt-blown PP cotton with a pore size of 1mm to filter the seawater again;
[0037] S2, using the KDF filter element to filter the seawater obtained in step S1;
[0038] S3, using the repeated freeze-thaw method to concentrate the seawater obtained in step S2;
[0039] S4, using a PVC alloy ultrafiltration membrane with a pore size of 0.01mm to filter the seawater obtained in step S3;
[0040] S5, using activated carbon to perform adsorption treatment on the seawater obtained in step S4;
[0041] S6. Dilute the seawater obtained in step S5 with sterile purified water, and then sterilize to obtain physiological deep seawater.

Embodiment 1
[0070] S1. Under the pressure of 0.3MPa, use polypropylene melt-blown PP cotton with a pore size of 5mm to perform preliminary filtration on the original seawater to remove solid impurities larger than 5mm in the water.
[0071] S2. Routinely detect the salt concentration and element content (potassium, sodium, chlorine, calcium, phosphorus and magnesium, etc.) of seawater. The detection method is as described above.
[0072] S3. Under the pressure of 0.3MPa, the original seawater is re-filtered with polypropylene melt-blown PP cotton with a pore size of 1mm to effectively remove bacteria, small molecular particles and suspended solids in the water.
[0073] S4. Use the KDF filter element to filter seawater to remove soluble metals and compounds such as lead, copper, mercury, nickel, chromium, and arsenic.
[0074] S5. Concentrate and remove excess salt in the seawater by repeated freeze-thaw method, and process until the volume of the seawater after concentration is 1% of th...

Abstract
The invention provides a preparation method of physiological deep seawater. The preparation method comprises the following steps: S1, primarily filtering original seawater by using polypropylene melt-blown PP cotton with the pore diameter of 5mm, and then filtering the seawater again by using polypropylene melt-blown PP cotton with the pore diameter of 1mm; S2, filtering the seawater obtained in the step S1 by using a KDF filter element; S3, carrying out concentration treatment on the seawater obtained in the step S2 by utilizing a repeated freezing and thawing method; S4, filtering the seawater obtained in the step S3 by using a PVC alloy ultrafiltration membrane with the pore diameter of 0.01 mm; S5, carrying out adsorption treatment on the seawater obtained in the step S4 by using activated carbon; and S6, diluting the seawater obtained in the step S5 by using sterile purified water to obtain the physiologic deep seawater. The physiological deep seawater prepared by the preparation method is balanced in various trace elements, safe and durable, and can be used for medical use.
Description
technical field [0001] The invention relates to the field of water treatment, in particular to a method for preparing physiological deep seawater. Background technique [0002] Deep seawater generally refers to seawater below 200m above sea level. The ocean area accounts for about 70.8% of the earth's surface area, the average depth of the ocean is about 4000m, and 95% of the seawater belongs to the deep seawater. Because sunlight is difficult to reach, photosynthesis in the deep seawater almost stops, and heterotrophy dominates. In addition, there is very little exchange with the surface seawater, and biological activities are not intense. Generally speaking, deep seawater has the following salient features: [0003] (1) low temperature. Because sunlight cannot be directly irradiated, compared with surface water, the temperature of deep seawater is lower, generally As the depth increases, the seawater temperature gradually decreases. The water temperature below 300m f...
