Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wastewater treatment, in particular to a high-concentration salt wastewater membrane separation treatment device and use method. BACKGROUND

[0002] High-concentration salt wastewater, namely high-salt wastewater, refers to wastewater with high salt content. Such wastewater is mainly derived from industrial production and part of domestic sewage, in which inorganic salt ions such as potassium ions, calcium ions, sodium ions, chloride ions, sulfate ions, etc. account for a considerable proportion, in addition, the wastewater may also contain some organic substances such as glycerol and low-carbon chain compounds, etc. At present, membrane separation technology is often used in the treatment of high-concentration salt wastewater. Membrane separation technology is a technology that separates solutes from solvents in a solution through a semi-permeable membrane based on the selective permeability of biological membranes. Its basic principle is to use the selective permeability of the membrane, that is, only molecules of a specific size and shape can pass through the semi-permeable membrane, while other molecules are retained.

[0003] Through the applicant's investigation, it is found that the traditional wastewater membrane separation treatment device mostly uses an entire membrane for filtration. For example, a high-salt wastewater filtration membrane treatment device disclosed in patent No. CN207537297U. Since the area of the entire filtration membrane is large, once the membrane surface is contaminated or clogged, the difficulty of cleaning and maintenance will be relatively large, and the entire filtration membrane must be replaced, which requires more time and resources to ensure the effective operation of the filtration membrane. In addition, the membrane surface is easily damaged during operation due to various factors (such as pressure, water flow rate, particle impact, etc.), resulting in a decrease in filtration efficiency. At the same time, impurity filtration and membrane treatment are mostly operated separately, resulting in low efficiency. In some improved equipment, the membrane is partially arranged in the opening of the filter plate, but this cannot ensure that the water is above the membrane area, and dead angles may be formed in some areas of the plate, causing poor water flow and affecting the filtration effect. In addition, the smaller membrane has poorer bearing capacity, and excessive water pressure can easily damage the membrane.

[0004] Therefore, the present application particularly needs to design a high-concentration salt wastewater membrane separation treatment device and use method to solve the above technical problems. SUMMARY

[0019] S2, filtering step

[0020] Through the water inlet pipe, the high-concentration salt wastewater to be filtered is added to the water tank.
