Equipment used for treating high-salt high-organic-matter wastewater

Abstract

The invention relates to the technical field of treatment equipment for salt-containing wastewater, and in particular relates to equipment used for treating high-salt high-organic-matter wastewater. The equipment comprises a material tank, a material inlet device, an evaporation device, a transfer device and a drying machine; and the external wastewater to be treated passes through the material tank, the material inlet device, the evaporation device, the transfer device and the drying machine in sequence to complete treatment, and the drying machine comprises a cylinder body, a rotating component and a plurality of stirring heating components. According to the equipment provided by the invention, the evaporation device and the drying machine are arranged, firstly evaporation treatment of the high-salt high-organic-matter wastewater is completed, then a viscous mixture is dried, so that the purpose of drying while stirring is realized, the purpose of all-dimensional drying is realized,and a phenomenon that the mixture is not dried thoroughly is avoided.

Description

technical field [0001] The invention relates to the technical field of treatment equipment for salty wastewater, in particular to equipment for treating wastewater with high salinity and high organic matter. Background technique [0002] In the prior art, the following three methods are usually used for the treatment of wastewater containing high salt and high organic matter: [0003] 1. MVR evaporation + centrifuge method, directly use MVR to evaporate. In the later stage of operation, impurities such as organic matter in the wastewater will continue to enrich, resulting in the inability to continue evaporation. At the same time, the evaporated precipitate is viscous and cannot be centrifuged; [0004] 2. MVR evaporation + reactor concentration method, using this process to run to a large amount of concentrated liquid in the later stage, it is easy to cause system blockage; [0005] 3. MVR evaporation + incineration method, this process is limited by conditions, the invest...
