Environment-friendly system and method for remotely monitoring industrial sewage discharge

Abstract

The invention discloses an environment-friendly system and method for remotely monitoring industrial sewage discharge. Water quality information at monitored places is acquired by a PH (Potential of Hydrogen) sensor, a COD (Chemical Oxygen Demand) detector and a flowmeter. Data information is acquired by a system power supply voltage sensor, a district power grid voltage sensor and a flowmeter. When the system power supply voltage sensor detects that the system power supply voltage is zero, a UPS (Uninterrupted Power Supply) supplies power. Secret discharge phenomenon is determined when the following information is simultaneously obtained, i.e., the district power grid voltage of the place monitored by the district power grid voltage sensor is normal, and the sewage discharge quantity of the place monitored by the flowmeter is increased. When site failure occurs, a customized circuit breaker drops out and trips, and a bridging type sampling switch sends out an alarm signal. After water quality, secret discharge and site failure information is acquired by a PLC (Programmable Logic Controller) processor, the information is transmitted to a monitoring center by a GPRS (General Packet Radio Service) module, and data is summarized, analyzed and processed by the monitoring center. The secret discharge, the site failure and sewage parameters, such as sewage discharge quantity, a COD value and a PH value are monitored in real time.

Description

technical field [0001] The invention relates to a monitoring system for industrial sewage discharge, in particular to a remote environmental protection anti-stolen discharge and discharge fault monitoring method and device, which are used to realize real-time monitoring of enterprise sewage discharge, sewage sneaky discharge and on-site faults. Background technique [0002] Water pollution is one of the main environmental problems facing our country, and industrial wastewater is the main cause of water pollution. With the development of my country's industry, the discharge of industrial wastewater is increasing day by day. After the industrial wastewater that does not meet the discharge standards is discharged into the water body, it seriously pollutes the water resources. [0003] Most of the current automatic monitoring systems for sewage discharge are a comprehensive online automatic monitoring system composed of modern sensing technology, automatic detection and control ...

Problems solved by technology

However, the current automatic monitoring system is difficult to effectively monitor illegal discharges, making the phenomenon of illegal discharges very rampant without reasonable punishment

Moreover, the on-site fault monitoring part of the current automatic sewage discharge monitoring system is not perfect. When the sewage valve is blocked and stopped, the overcurrent fault or the overload, short circuit, undervoltage and other faults of the power circuit will cause the circuit breaker to trip. , and the site is unattended, it will cause the monitoring system to stop working, causing the monitoring system to be paralyzed and the environment damaged
