Miscellaneous salt resource utilization method and miscellaneous salt resource utilization system

Abstract

The invention discloses a miscellaneous salt resource utilization method and a miscellaneous salt resource utilization system. The method comprises the following steps: S1, removing organic matters; S2, dissolving; S3, carrying out salt separation treatment. The system comprises an organic matter removal unit, a dissolving pool, a pretreatment system and a salt separation treatment system. With the method and the system of the invention, miscellaneous salt generated by industrial treatment or piled miscellaneous salt can be effectively treated, so that the problems that conventional miscellaneous salt cannot be eliminated and is excessively stacked and accumulated are solved, miscellaneous salt having high harm and incapable of being effectively treated can be subjected to resource utilization after being treated, the recycling rate of miscellaneous salt treatment can reach 70-96%, the purposes of harmlessness, reduction and recycling treatment of miscellaneous salt is truly achieved,and the environmental problem caused by direct landfill of the miscellaneous salt is relieved; and the huge operation cost caused by direct incineration of the miscellaneous salt can be avoided, the waste of energy and resources due to secondary solid waste landfill treatment after traditional incineration treatment is avoided, the byproduct crystalline salt obtained through treatment can be soldoutside, and the overall cost of miscellaneous salt treatment is reduced by 89-100%.

Description

Technical field: [0001] The invention relates to the field of miscellaneous salt treatment, in particular to a method and system for resource utilization of miscellaneous salts. Background technique: [0002] Miscellaneous salt is a kind of solid waste, mainly produced by industrial production and wastewater treatment. As a kind of hazardous waste, there has been no reasonable and effective method or means for the effective treatment of miscellaneous salt, which has caused miscellaneous salt treatment to become a hindrance to the development of environmental protection technology. a bottleneck. [0003] The generation of miscellaneous salt in industrial production is mainly due to the fact that in the actual production process, due to problems such as annual inspections of enterprises, equipment operation and maintenance, accidents, etc., the normal production process is forced to be interrupted, and raw materials cannot be reasonably converted into products. excreted in th...

AI Technical Summary

Problems solved by technology

However, due to the strong solubility of miscellaneous salts, but the extremely poor stability and solidification, if not handled properly, it will easily cause secondary environmental pollution and is defined as hazardous waste

With the strengthening of national environmental protection efforts, the requirements for the types of hazardous wastes that are landfilled or dumped are becoming increasingly stringent, and the scale of landfills or dumps is limited, and a large amount of miscellaneous salt cannot be processed, which not only limits the sustainable development of industrial production. Stable, healthy and green development, and it has also affected people's daily life. For the above problems, there is no effective solution to the above problems that have been published or reported in the literature.
