Abstract

The invention discloses a desulfurization waste water treatment zero-emission processing system and method. The system comprises a boiler sub system, an electric dust removing device, an evaporating device, a desulfurization device, a heat device, a desulfurization waste water tank, a steam turbine sub system, a recycling device, a heat exchange device and a sludge filter pressing device. The system further comprises a related fitting cleaning device, a dosing device, an electrical system and meter control for ensuring the long-term stable operation of the process system, the system has the advantages of less dosing, repeated utilization, partial waste water investment and operating treatment cost saving and the like, and the current problems encountered by industrial waste water zero-emission are solved.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment and environmental protection, in particular to a zero-discharge process system and method for desulfurization wastewater treatment. Background technique [0002] At present, my country's economy is developing rapidly, and at the same time, with the huge consumption of energy, environmental problems are becoming more and more 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. The zero discharge implemented in the field of industrial wastewater in my country, especially in t...
