Method for recycling non-radioactive production wastewater of nuclear power plant

Abstract

The invention relates to a method for recycling non-radioactive production wastewater of a nuclear power plant. The method comprises the following steps: firstly classifying non-radioactive production wastewater in a plant area according to main pollutant characteristics, and adopting the same type of treatment facility for the same type of wastewater or wastewater similar in water quality; and transporting the collected and treated non-radioactive production wastewater to a seawater pretreatment plant forebay of a circulating water system by virtue of a pipeline, carrying out seawater treatment, and then taking the treated wastewater as supplementary water of a cooling water system. The method provided by the invention is firstly applied to the nuclear power plant, and the problem of discharge of the non-radioactive production wastewater is solved by applying the method. The method provided by the invention reduces the intake quantity of the cooling water system on raw water, improves the water reuse rate of the whole plant, saves the operation management cost, and also can reduce the discharge of the non-radioactive production wastewater of the nuclear power plant and reduce the influence of the discharged water on the environment. The non-radioactive production wastewater recycling way provided by the invention can provide a reference for nuclear power project design adopting a seawater cooling tower in future.

Description

technical field [0001] The invention belongs to the technical field of waste water recycling in nuclear power plants, and in particular relates to a method for recycling non-radioactive production waste water in nuclear power plants. Background technique [0002] At present, on the one hand, nuclear power projects have many water systems. During normal operation, a large amount of water needs to be consumed to maintain the operation of the entire power generation system, and a large amount of wastewater will inevitably be generated. The large proportion of fresh water consumption of nuclear power projects in the total local water consumption will not only exacerbate the shortage of fresh water resources in my country, but also cause a certain impact on the surrounding environment and receiving water bodies due to the large and continuous discharge of wastewater. In the design of the water system of nuclear power projects, energy saving and consumption reduction and pollutant...
