Thermal power plant resin regeneration wastewater treatment method and system

Abstract

The invention belongs to the technical field of thermal power plant resin regeneration wastewater, and particularly relates to a thermal power plant resin regeneration wastewater treatment method andsystem. By means of a resin washing part treatment unit, a resin conveying part treatment unit, an anion resin regeneration part treatment unit, a cation resin regeneration part treatment unit and a resin mixing part treatment unit, automatic classified collection of high-salt-content wastewater and low-salt-content wastewater is realized through logic control of automatic valves, wherein the classified statistics and abnormal judgment alarm of high-salinity wastewater and low-salinity wastewater are realized through water quantity metering. According to the treatment method and system for theresin regeneration wastewater of the thermal power plant, the regeneration wastewater of a boiler make-up water treatment system of the thermal power plant and the regeneration wastewater of a condensation water precision treatment system can be reasonably treated, and subsequent wastewater recycling and thermal power plant water affair management are facilitated.

Description

technical field [0001] The application belongs to the technical field of resin regeneration wastewater in thermal power plants, and in particular relates to a treatment method and system for resin regeneration wastewater in thermal power plants. Background technique [0002] Power companies are large industrial water users, with huge water consumption and discharge. With the gradual implementation of various national environmental protection policies and regulations, the water intake quota of thermal power plants and other indicators are gradually tightened, and power companies will face the pressure of zero discharge of wastewater. In thermal power plants, water is an important working medium and cooling medium, which plays an extremely important role in the normal operation of thermal power plants. The quality of water directly affects the safe operation and economic efficiency of thermal power plants. [0003] For thermal power plants, in order to achieve zero discharge ...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that among the various types of wastewater generated by thermal power plants, the water quality of the recycled wastewater from the ion exchange resin method boiler feed water treatment system and the recycled wastewater from condensate polishing is relatively poor. The resin recycled wastewater from thermal power plants is collected and directly enters the industrial wastewater treatment system for treatment Treatment, or direct discharge, resulting in a large amount of industrial wastewater generation and discharge, which cannot meet the requirements of deep water conservation. At the same time, the cost of wastewater treatment is high, and subsequent recycling is difficult.
