Embodiment Construction

[0049] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described The embodiments are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of this specification.

[0050] Considering that based on the existing power station condensate polishing system, the waste water of different treatment stages, different sources, and different characteristics generated in the process of recycling and treating the invalid resin is often not distinguished, and is discharged into the same waste water pool; and then through Use correspond...

Abstract

The invention provides a wastewater treatment system, a method and a device for fine treatment of condensed water of power station. According to the system, a first resin trapper, a second resin trapper and a wastewater stepped utilization subsystem are additionally arranged and connected outside an original power station condensed water fine treatment system comprising a separation tower, a negative tower and a positive tower; the method comprises the following steps: separating first-class wastewater with relatively poor water quality and second-class wastewater with relatively good water quality, which are discharged from a power station condensed water fine treatment system, through the first resin trapper and the second resin trapper, and respectively carrying out resin recovery and filtration on the two types of wastewater to obtain filtered first-class wastewater and filtered second-class wastewater; and then conveying the filtered first-class wastewater and filtered second-class wastewater respectively to a preset wastewater pool in the wastewater stepped utilization subsystem and a recycling pool matched with the water quality grade, so that water in different recycling pools can be accurately and effectively reused in the power station condensed water fine treatment system subsequently according to the use requirements.

Description

technical field [0001] This specification belongs to the technical field of power station wastewater treatment, and in particular relates to a wastewater treatment system, method and device for power station condensate polishing treatment. Background technique [0002] Usually, the waste water generated by the condensate polishing system of the power station when recovering and treating the invalid resin will be uniformly discharged into the waste water pool, and then the waste water in the above waste water pool will be uniformly treated. [0003] Based on the existing wastewater treatment system, it is often impossible to effectively reuse the relatively good quality wastewater generated during the condensate polishing process of the power station, which also increases the cost of wastewater treatment. [0004] For the above problems, no effective solution has been proposed yet. Contents of the invention [0005] This specification provides a waste water treatment syste...
