Background technique
Water pollution index is to represent the technical indicator of the pollutant loads such as particle in water, bacterium, colloid.By calculating sample
The speed that product water blocks 0.45 μm of miillpore filter calculates the pollution index value of water, manually measures to realize.
Reverse osmosis technology is widely used in the water treatment field of power plant and other industries, and water pollution index (SDI) is anti-
The important water inlet index of permeability apparatus, the method generallyd use are monitored with SDI analyzer.Although existing SDI is automatic at present
Measurement device, but because it is only that can not achieve real time on-line monitoring and expensive, so power plant instead of manual operation
Generally use the manual measurement device of the lower SDI of price.But SDI has its limitation in the application:
1) SDI cannot be monitored on-line continuously and be reacted variation water quality situation in time, be unfavorable for searching variation water quality original in time
Cause is unfavorable for the operation steady in a long-term of reverse osmosis membrane；
2) easily there is biggish error in different people operation；
3) temperature when test film and measurement of different manufacturers production will affect measurement result.
Therefore, no matter from the angle of safe and stable operation, or from the angle increased economic efficiency, in feed water by reverse osmosis
