Treatment method and system for circulating water quality control

Abstract

The invention discloses a circulating water quality control treatment method and system, and relates to the technical field of seawater cooling utilization, and the method comprises the following steps: S1, adding an oxidizing bactericide into a pump suction inlet of a circulating water pool, continuously adding for 24 hours, the oxidizing bactericide being sodium hypochlorite; s2, sampling at regular time and detecting the content of residual chlorine; s3, if the content of residual chlorine detected in the step S2 exceeds the range, the adding concentration of sodium hypochlorite is changed; s4, regularly adding a non-oxidizing bactericide, and stopping adding the oxidizing bactericide before adding the non-oxidizing bactericide; and S5, after the non-oxidizing bactericide is added, continuously adding the oxidizing bactericide. The quality of the circulating water can be controlled by regularly adding the oxidizing bactericide and the non-oxidizing bactericide into the circulating water, and meanwhile, the reagents can be automatically and quantitatively added by adopting a specific control process, so that sufficient purification treatment on the circulating water can be ensured.

Description

technical field [0001] The invention relates to the technical field of seawater cooling and utilization, in particular to a method and system for controlling and treating circulating water quality. Background technique [0002] With the development of industrial production, the water consumption is getting larger and larger, and the phenomenon of insufficient water supply has appeared in many areas. Therefore, reasonable and saving water has become an important issue in the development of industrial production. The industrial application of circulating cooling water has completely solved the problem of water use. problem in order to achieve the purpose of saving water. [0003] However, in the seawater direct discharge circulation system, it is necessary to control the growth of organisms in the seawater. The conventional operation is to directly add oxidative bactericides or electrolytic chlorine into the seawater, and then the organisms in the seawater are prone to develop...

Problems solved by technology

[0003] However, in the seawater direct discharge circulation system, it is necessary to control the growth of organisms in the seawater. The conventional operation is to directly add oxidative bactericides or electrolytic chlorine to the seawater, and then the organisms in the seawater are prone to develop drug resistance, resulting in further The blockage of water mesh or drainage pipes will affect the normal use of circulating water, so it needs to be added alternately with non-oxidizing fungicides to prevent drug resistance
