Sewage treatment monitoring system

Abstract

The invention discloses a sewage treatment monitoring system. The system comprises a signal sampling module and an amplitude modulation calibration module, the signal sampling module uses a signal sampler J1 with the model of DAM-3056AH to sample a data signal in the sewage treatment monitoring system; the amplitude modulation calibration module uses an adjustable resistor RW1, an adjustable resistor RW2, a triode Q1 and a capacitor C3 to form an amplitude modulation detection circuit to adjust the signal waveform amplitude. In one path, an operational amplifier AR1, an inductor L1 and a triode Q3 are used for forming a frequency modulation circuit to filter high-frequency signal components in signals; in the second path, an operational amplifier AR3, a capacitor C4 and a capacitor C5 forma noise reduction circuit to reduce the signal-to-noise ratio; the in-phase input end signal of the operational amplifier AR1 influences the inverted input end signal of the operational amplifier AR3; two paths of signals can be enabled to be synchronous in amplitude and finally sent to a sewage treatment monitoring system terminal through a signal emitter E1, and data signals in the sewage treatment monitoring system can be sampled and calibrated and converted into correction reference signals of the sewage treatment monitoring system terminal.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment monitoring system. Background technique [0002] At present, sewage treatment in oil drilling, refining, chemical industry, electric power, pharmaceuticals, medicine and other industries has attracted increasing attention. Sewage treatment is related to the development of the entire ecological industry and is also an important link in the healthy development of human beings. There are certain loopholes in self-monitoring. With the development of big data, data monitoring has been carried out in sewage treatment. However, due to the pollution of different pollution sources, the sewage becomes different water quality. The corresponding sewage treatment processes are not the same. The processes involved There are more and more equipment, so it is necessary to continuously compare and analyze the collected sewage data to avoid errors in the data informatio...

However, due to the pollution of different pollution sources, the sewage becomes different water quality. The corresponding sewage treatment processes are not the same. The processes involved There are more and more equipment, so it is necessary to continuously compare and analyze the collected sewage data to avoid errors in the data information received by the sewage treatment monitoring system
