Abstract

The invention discloses a high-salt industrial wastewater treatment process system. The system includes a raw water equalizing pool, a mechanical accelerated clarification pool, a clear water pool, a multi-medium filter, a weak acid cation bed, a softened water pool, a self-cleaning filter, an ultrafilter, an ultrafilted water pool, a primary RO security filter, a primary RO instrument, a concentrated water pool, a secondary RO security filter, a secondary RO instrument, a tertiary RO instrument, a pre-desalted water tank, a lime device, a FeCl3 device, a PAM device, a MgO device, a soda ash device, a HCl device, a NaOH device, a scale inhibitor device and a reducing agent device; and the process system also comprises, related supporting, a cleaning system, an adding medicine storage system, a compressed air system, a wastewater neutralization system, an electrical system and an instrument control system in order to ensure the long-term stable operation of the process system. The high-salt industrial wastewater treatment process system has the advantages of operation at a high pH value all the time, effective avoiding of the pollution plugging of the RO instrument, and realization of investment and operation cost saving by utilizing the regeneration characteristic of weak acid cation resin.

Description

technical field [0001] The invention relates to the technical field of industrial wastewater treatment and environmental protection, in particular to a high-salt industrial wastewater treatment process system. 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. Industrial zero emission 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 key problem of the implementation of zero discharge in my country's industrial field is that the high-salt industrial wastewater at the end...
