Sewage treatment system

Abstract

The invention relates to a sewage treatment system. The sewage treatment system comprises a preheating system, a high-temperature steam generation system and an evaporation system, wherein the preheating system is used for preheating sewage; the high-temperature steam generation system is used for generating high-temperature steam; the evaporation system is connected with the preheating system andthe high-temperature steam generation system; the evaporation system comprises a plurality of evaporation modules, any one of the evaporation modules can be isolated, and under the heating effect ofhigh-temperature steam, the other evaporation modules cooperate to conduct step-by-step evaporation and concentration on preheated sewage to obtain a concentrated solution and condensate water. Due tothe fact that any one of the multiple evaporation modules can be isolated, cleaning or overhauling can be conducted conveniently, and when the evaporation module is isolated, normal work of the otherevaporation modules cannot be affected, and therefore continuous, stable and efficient work of the sewage treatment system is achieved. Except for the isolated evaporation modules, the other evaporation modules can cooperate with each other to evaporate and concentrate the sewage step by step, so as to achieve a better treatment effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment system. Background technique [0002] At present, for conventional sewage treatment systems, regular cleaning is required to ensure that the sewage treatment effect is maintained at a good level. However, when cleaning the sewage treatment system, it usually needs to be shut down for cleaning, which will cause the stoppage of sewage treatment work, delay the progress of sewage treatment, and cause relatively large economic losses to the enterprise. Contents of the invention [0003] Based on this, it is necessary to provide a sewage treatment system that can ensure continuous, stable and efficient sewage treatment. [0004] A sewage treatment system comprising: [0005] Preheating system for preheating sewage; [0006] High temperature steam generation system for generating high temperature steam; [0007] The evaporation system is connected with...
