For drinking water treatment units or enterprises, two contradictions are generally faced in the process, namely the contradiction between the raw water quality with increasingly serious pollution and the effluent quality which is urgently required to be improved, and the contradiction between the high effluent quality and the high treatment cost. In addition, most drinking water treatment units in China still face a severe practical problem, namely that the backward treatment process and operation management are gradually not suitable for the changeable drinking water supply situation. This problem can be solved by the patent "a multi-stage barrier modular graded drinking water treatment system".
The problem faced in the aspect of operation is that the existing operation mode is adapted and regulated based on the original process and cannot be adapted to the variable drinking water grading treatment process.

According to the scheme, the emergency wind control system comprises a water inlet quality monitoring device and a water outlet quality monitoring device, wherein the water inlet quality monitoring device is an emergency response unit, and when the water inlet quality exceeds a normal value or contains toxic and harmful substances, a detection signal is transmitted to the automatic control system for emergency response; and the effluent quality monitoring is a risk control unit, and when the effluent quality is detected to be not in accordance with the national standard, a detection signal is transmitted to the automatic control system for risk control.
According to the scheme, the on-line monitoring system carries out conventional water quality monitoring on the water treated by the pretreatment module, the conventional treatment module and the advanced treatment module, transmits a detection signal to the automatic control system, and regulates and controls the operation parameters of each treatment module by evaluating the treatment effect inside each treatment module and the mutual influence among the treatment modules so as to achieve the optimal operation effect.
The operation mode of the system of the invention is as follows (see figure 2):
the method comprises the steps that source water enters a factory, the pollutant level in the water is subjected to response evaluation through an online monitoring system, the adopted technical scheme and treatment route are determined according to different pollution levels, the evaluation result is transmitted to an automatic control system, a pipeline and a valve switch are adjusted through the automatic control system to form a drinking water treatment scheme corresponding to the water quality, various pollutants are effectively removed in the drinking water treatment system, the water quality monitoring system transmits the data of the water outlet end of each module to the automatic control system, the operation parameters of each module are conveniently regulated and controlled to achieve the optimal operation effect, the water passing through the drinking water treatment system enters a risk control unit in an emergency pneumatic control system, the risk control unit gives risk assessment for the water quality of the outlet water according to national standards and is used as the basis of graded water supply, and the water is directly discharged through the risk control unit, and the part which fails to pass through the risk control unit is subjected to reflux route selection by the automatic control system according to the risk level, and enters the drinking water treatment system again to complete the circular treatment.
If the online monitoring system evaluates that the water quality is better and when there is no sudden pollutant, the automatic control system closes the pipeline valve leading to the advanced treatment module or reduces the water volume leading to the advanced treatment module and opens the valve of the overtaking pipeline, most of the effluent passes through the advanced treatment module via the overtaking pipeline and directly enters the risk control unit of the emergency wind control system, and a small part of water still needs to pass through the advanced treatment module to ensure the activity of microorganisms in the activated carbon in the advanced treatment module, namely, the mode one: emergency response, pretreatment, conventional treatment and risk control, wherein the risk control unit evaluates the treated water quality, if the treated water quality meets the national standard, the treated water can be directly disinfected and discharged, 50-80% of the water enters the conventional treatment, and 20-50% of the water enters the advanced treatment module; if not, the water flows back to the next water treatment module of the water outlet module, namely the advanced treatment module, by the control system for further treatment.
