Circulating cooling water ozone bypass-flow treatment system and method

Abstract

The invention provides a circulating cooling water ozone bypass-flow treatment system and method. The circulating cooling water ozone bypass-flow treatment method comprises the following steps: introducing part of circulating cooling water in a water storage tank or filter tank into an ozone reaction tower, introducing ozone into the ozone reaction tower so that higher-concentration ozone water is formed in the ozone reaction tower, staying for some time, sending the treated ozone water solution with certain sterilization and algae removal functions into the water storage tank, and keeping the residual ozone amount of the circulating cooling water in the cooling tower or water storage tank at lower level, thereby performing the sterilization and algae removal functions. The measurement control technique of the system is based on measurement of OPR (oxidation-reduction potential) probes arranged in two different positions: one probe is arranged in the water storage tank, and used for monitoring the residual ozone amount in the circulating cooling water, thereby preventing the overhigh residual ozone amount from corroding the equipment; and the other probe is arranged in the ozone reaction tower and used for monitoring the concentration of the ozone water, thereby ensuring the water treatment effect and effectively solving the problems of corrosion, scaling and the like in the circulating cooling water.

Description

technical field [0001] The invention relates to a cooling tower circulating cooling water treatment technology, in particular to a circulating cooling water ozone bypass treatment system and method. Background technique [0002] The consumption of cooling water accounts for 50-90% of the total water consumption of enterprises in different industries. Due to the increasingly scarce water resources, industrial cooling water is usually recycled. Long-term recycling of cooling water will inevitably bring about problems of scaling, corrosion and microbial growth and deposition. Only by solving these three problems can we stabilize production, save resources and energy, thereby reducing environmental pollution and improving economic benefits. These three main problems are directly or indirectly related to microorganisms in the cooling water system. On the one hand, slime-forming bacteria, sulfate-reducing bacteria, nitrifying bacteria, iron bacteria, algae, etc. in circulating coo...
