Problems solved by technology

Among them, the method of physical blending is relatively simple and low in cost, but it is difficult to find a suitable fluorescent tracer; both polymer modification and fluorescent monomer copolymerization are to improve the water treatment agent itself, but its production cost is high, which affects its performance. Widely popularized and applied in small and medium-sized circulating cooling water systems

Abstract

The invention discloses a method for detecting the content of compound water treatment agent in industrial circulating cooling water by adopting fluorescent tracer. Disodium 4,4'-bis(2-sulfostyryl) biphenyl fluorescent tracer and the water treatment agent containing acrylic acid-hydroxypropyl acrylate-AMPS copolymer and hydrolytic polymaleic anhydride are blended, so that fluorescence-labeled compound water treatment standard additive is prepared, the mass concentration of the acrylic acid-hydroxypropyl acrylate-AMPS copolymer and the hydrolytic polymaleic anhydride of the fluorescence-labeled compound water treatment standard additive is 2.5kg / M3, 40g / M3 to 50g / M3 of fluorescence-labeled compound water treatment standard additive is added into industrial circulating cooling water and industrially circulated, and if the measured fluorescence value is less than 5470 plus or minus 100, then the fluorescence-labeled compound water treatment standard additive needs to be added. The content of the compound water treatment agent can be quantitatively monitored according to the fluorescence intensity of the circulating cooling water, so that the compound water treatment agent can be conveniently added in real time in order to guarantee the scale inhibition effect of a circulating cooling water system.

Description

technical field [0001] The invention relates to a method for detecting the content of a compound water treatment agent in industrial circulating cooling water by using a tracer substance, and belongs to the field of industrial water treatment detection. Background technique [0002] In industrial water treatment systems, water treatment agents have been widely used, and the concentration control of water treatment agents has always been one of the difficult problems in water treatment management. Usually, the concentration of the water treatment agent can be monitored by manual sampling to detect the total phosphorus value, but this method is time-consuming, the control lags, and it is easy to cause the waste of the water treatment agent and the scaling and corrosion of the system. In recent years, with the promotion and use of environmentally friendly phosphorus-free water treatment agents, the concentration of water treatment agents cannot be monitored and controlled by co...
