Scaling,cleaning and water quality stability disposal technology of the circulation cooling water system of the oxygen making works are presented.

For the washing water system of blast furnace gas,based on the reaction mechanism of water quality purification(flocculation) and water quality stability(scale inhibitor and dispersant) techniques,and through the experiment of the selective program of agent prescription,the treatment technology of water quality suitable for circulating cooling water system has been studied.

According to the processes such as flushing, chemical cleaning, prefilming and normal treatment etc in the practice of water quality stability treatment of circulating cooling water system and the technical requirements for system drainage, sweep, water filling and substitution, monitoring and normal dosing etc were discussed.

The stability of water quality is very important to industrial circulating cooling water and plant production.

Electrochemical sterilization is a novel technique for water quality stabilization and has an important significance for elimination of the eutrophication of surface water body caused by the water quality stabilizer with phosphorus series formulation.

Based on the production practice of the circulating water system operation,the relation between the pass-by flowing treatment and the suspending solid,the elimination of the floating solid,the shortcomings of the glass fiber reinforced plastics cooling tower,or the inclusive perfect concept of water quality stabilization have been put forward for the designers to refer to.
