Embodiment Construction

[0030] A kind of preparation method of industrial new water of the present invention is characterized in that, comprises the steps:

[0031] 1) Industrial new water consists of five parts, namely groundwater, river water, reservoir water, advanced treatment reuse water and demineralized water; among them:

[0032] The water quality indicators of groundwater are: temperature 12-14°C, suspended solids 4-4.8ppm, total dissolved solids 240-250ppm;

[0033] The water quality indicators of the river water are: temperature 13-15°C, suspended solids 12-14ppm, total dissolved solids 130-140ppm;

[0034] The water quality indicators of the reservoir water are: temperature 19-21 ℃, suspended solids 18-20ppm, total dissolved solids 100-120ppm;

[0035] The water quality indicators of advanced treatment reuse water are: temperature 26-28 ℃, suspended solids 8-10ppm, total dissolved solids 980-1000ppm;

[0036] The water quality indicators for desalinated water are: temperature 26-28°C, s...

Abstract

The invention relates to a preparation method of new industrial water. The method comprises steps as follows: the new industrial water comprises five parts including underground water, river water, reservoir water, recycled water obtained through advanced treatment and desalted water; 2) a mathematical model is constructed; 3) the mathematical model is solved in the step 2), and the mixing proportion of all kinds of water is solved with MATLAB scientific calculation language software; the water quality of the finally prepared new industrial water meets the following indexes: the temperature issmaller than 24 DEG C, suspended solids are smaller than 16 ppm, and total dissolved solids are smaller than 300 ppm. The mathematical model is constructed for computer analog computation, the composition ingredients and proportion of the new industrial water are adjusted, recycling of reclaimed water is increased on the premise that safety and reliability of water consumption in enterprises areguaranteed, exploitation of underground water resources is reduced, and the purposes of reducing the water cost, saving the investment and protecting the ecological environment are achieved.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a preparation method of industrial new water. Background technique [0002] The iron and steel industry is a major player in water consumption and sewage discharge in the industrial field. Its water consumption accounts for about 14% of the national industrial water consumption, and its sewage discharge accounts for about 12% of the total industrial discharge. The Outline of the Twelfth Five-Year Plan for National Economic and Social Development stipulates that water consumption per unit of industrial added value needs to be reduced by 30%. The Ministry of Water Resources recently stated that "in the future, it is possible to control the total amount of water used by large water users in key areas. After the water consumption quota is used up, the newly added water can only be met through the transfer of water rights and the use of non-traditional water sources." In addi...
