High-salt wastewater treatment process system and method thereof

Abstract

The invention discloses a high-salt wastewater treatment process system and a method thereof. the system comprises a desulphurization treatment system, a raw water regulating tank, a super softening sedimentation basin, a super ozone device, a clean water basin, a multi-media filter, a weak acid cation bed, a sodium bed, a ultraviolet device, a tubular membrane, a security filter, a SCRO, a special separating membrane, a high pressure reverse osmosis device, a flue evaporation crystallization drier, a wastewater tank and a recycled water tank. In order to ensure the long-term stable operationof the process system, the related matched cleaning device, a chemical dosing device, an electrical system and instrument control are also included. The system has the following advantages: chemical dosage is less; wastewater is reutilized, and investment and operation treatment costs of part of wastewater are saved. The problems in zero emission of high-salt wastewater in the prior art are solved.

Description

Technical field [0001] The invention relates to the technical field of industrial wastewater treatment and environmental protection, in particular to a high-salt wastewater treatment process system and method. Background technique [0002] At present, my country's economy is developing at a high speed. At the same time, with the huge consumption of energy, environmental problems are becoming increasingly serious. In order to improve the current environmental situation, the country's management of the three wastes is becoming more and more stringent. The zero discharge of industrial wastewater has been accepted by many enterprises and professionals, and it has gradually begun to be implemented in the industrial field. As water is an indispensable resource in the industrial field, the discharge of concentrated brine is an important environmental indicator. my country's implementation of zero discharge in the field of industrial wastewater, especially in thermal power plants, the k...

AI Technical Summary

Problems solved by technology

Miscellaneous salts are produced by waste heat evaporation of flue gas, which may be affected by environmental protection policies in the next stage, while membrane method + evaporation crystallization, the cost of softening agents is too high, and the operation and maintenance requirements are relatively high
