Abstract

The invention discloses a bactericide composition. The composition comprises a Fumei-series bactericide and a quaternary ammonium bactericide. The invention further discloses application of the bactericide composition in water treatment. The sludge stripping capability, bacterium killing capability and carbon steel coupon corrosion speed of a water treatment agent of the bactericide composition are tested, and testing results indicate that the bactericide composition serving as a water treatment agent has a good sludge stripping effect, quick bacterium killing effect, long duration and excellent corrosion inhibition effect for carbon steel coupons.

Description

Technical field [0001] The invention relates to a bactericide composition and the application of the bactericide composition in industrial cooling circulating water treatment. Background technique [0002] The control of bacteria and algae in the circulating cooling water system is generally controlled by adding fungicides. Commonly used fungicides are divided into two categories, oxidizing and non-oxidizing fungicides. Commonly used oxidizing fungicides mainly include chlorine gas, sodium dichloroisocyanurate (referred to as Youlujing), trichloroisocyanuric acid (referred to as strong chlorin), etc.; commonly used non-oxidizing fungicides mainly include quaternary ammonium organics, quaternary Phosphonium salt organics, isothiazolinone, glutaraldehyde, etc. Oxidizing bactericides are widely used because of their low price, but they are easily affected and interfered by circulating cooling water pH, organic matter, scale and corrosion inhibitors, etc., which reduce their bacter...
