By property.In addition, carrying out feedback control when handling water processing establishment and by the detection abnormal conditions such as measurement desulfurization wastewater component
System, and operating condition etc. is changed as countermeasure, from abnormality to stable state, however, in pair for executing feedback control
Abnormal due to having had already appeared fouling etc. in plan, so having a problem that, i.e. washing, chemistry injection etc. needs high
Cost, to make water processing establishment back to stable state.
Therefore, in the related art, it has been proposed that measurement will be supplied to the water quality of the raw water of water processing establishment, and right
The injection rate of the chemical reagent such as the flocculant based on measurement result carries out feedforward control, however, because directly measuring the water of raw water
Matter, it is difficult to execute reply water quality rapid fluctuations control, furthermore in power plant desulfurization wastewater, desulfurization wastewater composition due to heat
The variation of type, the generation load of coal etc. and in the case where significantly fluctuating, cause the water quality of waste water reverse osmosis membrane apparatus (such as
Desalter) in film surface on the problems such as generating dirt dirt, therefore can not achieve the pre-determined characteristics as water processing establishment.Cause
This, even if, also there is an urgent need to introduce a kind of water treatment system, which can in the case where the service conditions such as boiler significantly fluctuate
Performance with stable operation without deteriorating water processing establishment.
