Efficient algae-inhibiting method for water circulation system of cooling tower

Abstract

The invention provides an efficient algae-inhibiting method for a water circulation system of a cooling tower. Silver ion-containing hydrogen peroxide is used as an algae inhibitor. When the cooling tower starts running, 3.5-4.5 g of silver ion-containing hydrogen peroxide is added in every liter of circulation water; and the silver ion-containing hydrogen peroxide is supplemented one time every 7-10 days. A stable sanitizer (the silver ion-containing hydrogen peroxide) is used as an algae inhibitor to replace conventional sanitizer, algaecide and biocide. The algae inhibitor is long in action time and obvious in effect, and can inhibit growth of the algae in the circulation water and effectively control production of biological membranes. The silver ion-containing hydrogen peroxide is colorless and has no smell, is mutually soluble with water, can be decomposed into water and oxygen, is safe and environment-friendly, is harmless to human, is not influenced by temperature and pH value, has a broad spectrum bactericidal effect, and can achieve an object of energy conservation and cost consumption.

Description

technical field [0001] The invention relates to the technical field of water treatment in industrial circulating water systems, in particular to a method for efficiently inhibiting algae in a cooling tower water circulating system. Background technique [0002] During the operation of the cooling tower, the circulating cooling water system is affected by the temperature and environment, and there will be bacteria and biofilms, ① affecting heat transfer efficiency and increasing energy consumption: research shows that when there is a 0.5mm biofilm , will increase the energy consumption by 20%. If the biofilm on the heat exchange equipment reaches 1mm, it will increase the energy consumption of the system by 55%. In severe cases, the cooling system cannot meet the process requirements; The biofilm and bioslime attached to the heater will isolate the chemical treatment agent from the equipment, making the corrosion inhibitor and scale inhibitor ineffective; ③Increasing equipmen...
