Embodiment 1
[0026] A kind of method utilizing yellow water to make bartender liquid, comprises the following steps:
[0027] (1) Add attapulgite to 3L of fresh yellow water, the addition of attapulgite is 0.5% of the quality of fresh yellow water, then stir at room temperature for 6h, let stand to clarify and get the clear liquid, and obtain the first-level clear liquid 2.9 L;
[0028] (2) Microfilter the first-stage clear liquid with a 0.2 μm inorganic ceramic membrane to remove residual attapulgite particles, and the operating pressure is 0.3 MPa to obtain 2.88 L of the second-stage clear liquid;
[0029] (3) The second-stage supernatant was nanofiltered with an organic membrane with a molecular weight cut-off of 300, and the membrane pressure was controlled to be 1.5 MPa to finally obtain 2.6 L of colorless and transparent liquor.
Embodiment 2
[0031] (1) Add attapulgite to 6L of fresh yellow water, the addition of attapulgite is 0.6% of the fresh yellow water quality, then stir at room temperature for 6.5h, let stand to clarify and take the clear liquid, and obtain the first-level clear liquid 5.8L;
[0032] (2) Microfilter the first-stage clear liquid with a 0.2 μm inorganic ceramic membrane to remove residual attapulgite particles, and the operating pressure is 0.2 MPa to obtain 5.73 L of the second-stage clear liquid;
[0033] (3) The second-stage clear liquid is nanofiltered with an organic membrane with a molecular weight cut-off of 300, and the membrane pressure is controlled at 1.0 MPa to obtain 5.3 L of colorless and transparent liquor.
Embodiment 3
[0035] A kind of method utilizing yellow water to make bartender liquid, comprises the following steps:
[0036] (1) Add attapulgite to 9L of fresh yellow water, the addition of attapulgite is 0.8% of the fresh yellow water quality, then stir at normal temperature for 8h, let stand to clarify and get the clear liquid, obtain the first-level clear liquid 8.5 L;
[0037] (2) Microfilter the first-stage clear liquid with a 0.2 μm inorganic ceramic membrane to remove residual attapulgite particles, and the operating pressure is 0.5 MPa to obtain 8.32 L of the second-stage clear liquid;
[0038] (3) The second-stage supernatant was nanofiltered with an organic membrane with a molecular weight cut-off of 300, and the membrane pressure was controlled to be 2.0 MPa, and finally 7.6 L of colorless and transparent liquor was obtained.
[0039] The fresh yellow water in Embodiment 1 to Embodiment 3 is taken from the production workshop of Luzhou Laojiao Co., Ltd. Compared with the yell...
