In one embodiment, as shown in Figure 1, providing a kind of monitoring method of clarifier, this method includes following step
It is rapid:
S100 obtains the primary purification rate lower limit value P of clarifiermin。
S200 obtains the current import pollutant concentration ρ of clarifierinWith current outlet pollutant concentration ρout。
S300, it is previous according to current import pollutant concentration and working as current outlet pollutant concentration calculating acquisition clarifier
Secondary purifying rate.
S400, judges whether current primary purification rate is less than or equal to primary purification rate lower limit value；If so, thening follow the steps

Speed, the current air volume 200m for such as exporting blower3/ h, at this time purification efficiency η=(ρ of clarifierin-ρout) * V=(100ug/
m3-20ug/m3)*200m3/ h=16mg/h reduces the energy consumption of clarifier in this way while guaranteeing higher purification efficiency.
If detecting obtained current import pollutant concentration is 100ug/m3, the current pollutant concentration that exports is 80ug/m3It is current at this time
Although the corresponding tertiary gradient of the credit rating of environment, due to current import pollutant concentration and current outlet pollutant concentration
Difference is smaller, i.e., the clean-up effect of purifying part is poor in current purge device, thus can it is appropriate improve blower revolving speed, such as
The current air volume 500m for exporting blower3Purification efficiency η=(ρ of/h clarifier at this timein-ρout) * V=(100ug/m3-
80ug/m3)*500m3/ h=10mg/h, to guarantee that clarifier reaches higher purification efficiency.It can make in above-described embodiment net
