Hydrogen-rich liquid biological detergent and preparation and application methods thereof

The invention discloses a hydrogen-rich liquid biological detergent and preparation and application methods thereof. The hydrogen-rich liquid biological detergent is prepared from raw materials including solvent and hydrogen dissolved inside the solvent, wherein the degree of saturation of the hydrogen inside the solvent is 0.1-100%, and the solvent is purified water or drinkable tap water. The preparation and application methods of the hydrogen-rich liquid biological detergent comprise the following steps of S1 preparing hydrogen, then inletting the hydrogen into the solvent for more than 5 min to obtain the hydrogen-rich liquid biological detergent of different degrees of saturation; S2, applying the hydrogen-rich liquid biological detergent to soaking and washing objects to be washed and cleaned including clothes, fabric, greasy dirt, ceramics, metal and glass; S3, electrolyzing water through a method of electrolyzing distilled water through 2-24 V direct current and performing water-gas separation and dry
