Abstract

The invention discloses a sterilization and synergy stripping agent for circulating water treatment. The sterilization and synergy stripping agent is prepared from the following components in percentage by weight: 5-15% of sodium bromide, 5-25% of alkylphenol polyoxyethylene, 2-10% of polyethylene glycol and 50-80% of water; large alkylphenol in the alkylphenol polyoxyethylene is alkylphenol with9-12 pieces of carbon, the mole number of ethylene oxide in the alkylphenol polyoxyethylene is 3-15, and the alkylphenol polyoxyethylene is selected from one or more components of octaphenyl polyoxyethyiene, nonylphenol polyoxyethylene ether and alkyl-polyoxyethylene; and the theoretical relative molecular mass of the polyethylene glycol is 200-800, and the polyethyl glycol is selected from one ormore components of polyethyl glycol 200, polyethyl glycol 400, polyethyl glycol 600 and polyglycol 800. According to the sterilization and synergy stripping agent for circulating water treatment, thesterilization effect of a chlorine-system oxidized sterilizing agent can be effectively enhanced, and the sterilization and synergy stripping agent permeates into slime to achieve the effect of stripping the slime.

Description

technical field [0001] The invention relates to the technical field of industrial circulating cooling water treatment, in particular to a bactericidal synergistic stripping agent for circulating water treatment. Background technique [0002] In the industrial circulating cooling water system, the temperature, pH, nutrient source, dissolved oxygen and other factors of the circulating cooling water provide a suitable environment for the reproduction of microorganisms; and with the concentration of the circulating cooling water, the reproduction of microorganisms will be aggravated. The growth and reproduction of microorganisms will cause corrosion, slime deposition and other hazards, which not only reduces the heat exchange cooling effect of heat exchangers and cooling towers, deteriorates water quality, but also reduces the efficacy of corrosion inhibitors, scale inhibitors and biocides, directly Affect production and bring economic losses. Therefore, the treatment of circul...
