Problems solved by technology

[0006] 2. The mineral components to be removed must be unstable under certain conditions
[0009] ① There is no research on the principle and regularity of crystal precipitation, and the control parameters of the aeration method are given
[0010] ②Simple application of underground hot water or sewage aeration methods, no pre-precipitation of CaCO for these methods 3 In-depth research on the principle and feasibility of the system, even though it is found that the expected pre-sinking effect has not been achieved, there is no way to solve it

Embodiment Construction

[0056] In conjunction with Fig. 1, take a certain water source existing in the fluvial sedimentary sandstone of the Miocene Fengshan Formation of the Upper Tertiary as an example, the specific implementation of the present invention is as follows: the water quality and water quantity of the water source are stable, and the strontium content is 0.39-0.43mg / L, the content of metasilicate is 49.4-58.0mg / L, which belongs to sodium calcium bicarbonate mineral water containing strontium and metasilicate. The resulting mineral salt precipitates as calcium carbonate (CaCO 3 ), the limit precipitation amount at 40°C and 90°C was 27.4mg / L and 122.6mg / L respectively. Assuming that the highest drinking temperature is 95°C, the limit metastable calcium concentration is 39.5 mg / L, and the limit metastable bicarbonate concentration is 320.3 mg / L. Use one of these two values ​​as the method control parameter.

[0057] The operation steps are as follows:

Abstract

A predeposition process for the natural drinking mineral water features that CO2 free air aeration, returning CaCO3 deposit, separation of deposit by natural deposition and fabric filter, and mixing air are used. Its system is composed of air compressor, air-water separator, air-cleaning buffer tank, alkali solution tank for washing gas, boosting pump, water tank, etc. Its advantages are high cleaning effect and retaining the coherent mineral components to maximum.

Description

technical field [0001] The invention relates to a pre-sedimentation method for drinking natural mineral water. Background technique [0002] Some mineral water containing specific mineral components often precipitate CaCO due to the difference between the underground environment and the surface environment after mining. 3 Precipitation and precipitation of mineral salts such as hydrated oxides of iron and manganese. It is more common for bottled mineral water to precipitate mineral salts when it is heated for drinking. Although the national "Drinking Natural Mineral Water" technical standard (GB8537-1995) stipulates that "a very small amount of natural mineral salt precipitation is allowed" in the product, it is not recognized by consumers. In particular, the mineral salt precipitation precipitated from bottled mineral water when it is heated for drinking is often no longer a "very small amount". These mineral salt precipitation suspended in mineral water give consumers th...
