The main problems lying ahead of recirulating cooling water treatment techniques in thermal power plants of our country after reform of the power system and the development direction of said techniques in the future have been presented. Based on the practical demand and possibility at present

it is considered that the enrichment factor of circulatory water at each thermal power plant in the near future should be greater than three

and taking this factor as a control target. For this reason

eight points of recommendation have been put forward as follows: （1） perfection of external treatment method for circulatory water; （2） development of new stabilizing agents and high-effective complex prescription; （3） strengthening the research of anticorrosion technology for condenser tubes; （4） carrying out the study on technique of using urban sewage as recirculating water; （5） exploring application of other pestisides; （6） strengthening application of automatic control techniques; （7） carrying out the study of descaling technique during the time of operation; （8） assigning fixed points to produce agents used for circulatory water treatment.
