1. A stabilized electromagnetic base liquid having a pH value between 12 and 14, an oxidation reduction potential between about −1.0 and −1.8 v comprising a exothermic reaction mixture of
(i) 20-30 parts by weight ratio alkali metal hydroxide,
(ii) 20-30 parts by weight ratio non-alkali metal,
(iii) 2-6 parts by weight ratio ammonia, and
(iv) 31-140 parts by weight ratio water resulting in electromagnetic base liquid with hydrated electrons (eaq−)
to which reaction mixture a direct current is applied to stabilize the hydrated electrons (eaq−) and the electromagnetic base liquid.
 
4. A high-salt wastewater treatment with the stabilized electromagnetic base liquid of claim 1 comprising the following steps:
Step 1: pump the wastewater into a wastewater container and perform a sand filtration and ultrafiltration for the removal of organic macromolecules and inorganic particles in the wastewater;
Step 2: pump the filtered wastewater into a sedimentation tank and add the stabilized electromagnetic base liquid into the wastewater for the removal of calcium and magnesium, obtaining a concentrated brine with electromagnetic base liquid;
Step 3: pump the concentrated brine into a nanofilter with a nanofiltration membrane pressure of 2.5 MPa for desalination to obtain reclaimed water and salts;
Step 4: place the salts in an evaporation tank and dry the salts with high-temperature incineration or evaporation crystallization; and,
Step 5: recycle the reclaimed water.
 
5. A method for preparing a stabilized electromagnetic base liquid comprising the following steps:
Step 1: as weight ratio, weigh and take 20-30 parts of alkali metal hydroxide and 20-30 parts of non-alkali metal; mix the alkali metal hydroxide and non-alkali metal uniformly to obtain the mixture;
Step 2: add a first part of ammonia water to the mixture for a reaction of 1-2 hours, obtaining the preliminary reaction mixture; as weight ratio, the first part of ammonia water is 1 to 2 parts of ammonia and 20 to 40 parts of water;
Step 3: when the temperature of preliminary reaction mixture reaches 110°, add a second part of ammonia water to the mixture for a reaction of 4-6 hours; control the reaction temperature between 110-160°, obtaining the complete reaction mixture; as weight ratio, the second part of ammonia water is 1 to 4 parts of ammonia and 10 to 40 parts of water;
Step 4: as weight ratio, add 1-60 parts of water to the complete reaction mixture for dilution, obtaining the diluted mixture;
Step 5: filter the diluted mixture and let it stand for 10-24 hours, obtaining the filtrate;
Step 6: apply a plasma generator with direct current to process the filtrate by the plasma jet generated in the discharge process to obtain a electromagnetic base liquid with following characters: a pH value between 12 and 14; oxidation reduction potential value between −1.0 and −1.8 v; with no corrosivity; and with stabilized hydrated electrons (eaq−−).
