In thermal power plants

intermediate water is mainly used as make-up water for the circulating water.Directing against the problems exisiting in reusing the intermediate water in thermal power plants

such as higher content of organic matters

ammonia

nitrogen

oils

phospher

and salts etc.

study and analysis have been carried out.It is believed that the treatment process of make-up water for circulating water

i.e.lime treatment + composite water quality stabilizing agent treatment

is more suitable for reusing intermediate water in thermal power plants.The bacteria-killing treatment of circulating water has to be strengthened

so as to ensure the cleaning effectiveness of rubber-ball cleaning system for circulating water

and increase flow speed of the circulating water

preventing corrosion of condenser tubes

at the same time

the prevention of corrosion for circulating water pipelines and for cement structural members of the cooling tower has also to be strengthened;increasing aeration time of waste water in aerobic pool

or increasing the amount of aeration

can effectively decrease the content of ammonia and nitrogen in the effluent water.
