Generate regulatory requirements for units

Industrial total water monitoring: Monitor the industrial total water flow rate (cubic meters) and instantaneous flow rate (liters/second).

Monitoring of water volume and liquid level in wastewater collection tank: Monitor the liquid level height (in centimeters) and water volume (in cubic meters) of the wastewater collection tank. If there are multiple collection tanks or buckets with bottom not connected in series, each collection tank or bucket needs to be monitored.

Industrial wastewater discharge monitoring: If an enterprise has industrial wastewater discharge in addition to scattered industrial wastewater, it needs to monitor the industrial wastewater discharge. The monitoring factors are the industrial wastewater discharge flow rate (cubic meters) and the instantaneous industrial wastewater discharge flow rate (liters/second).

Video surveillance: Video surveillance of wastewater collection tanks. If there are multiple collection tanks or buckets, the video must be fully covered.

2、 Acceptance standards

Acceptance conditions

The construction content of the on-site monitoring system meets the requirements of the parameter monitoring subsystem

The construction content of the on-site monitoring system complies with the requirements of the parameter monitoring subsystem in the "Dongguan City Pollution Source Online Monitoring Construction Technical Guidelines".

Equipment selection meets the requirements of equipment configuration

The selection of equipment and instruments complies with the equipment configuration requirements of the "Dongguan City Pollution Source Online Monitoring Construction Technical Guidelines".

Data acquisition and transmission device

Integrate reliable industrial wireless communication modules, coupled with efficient and stable power supply solutions, to provide effective support for long-term network operation of wireless communication modules. The data acquisition and transmission instrument shall support HJ 212 "Data Transmission Standard for Pollutant Online Monitoring (Monitoring) System" and the expanded protocol content (factor coding) in this technical guide.

In order to ensure the stability, reliability, accuracy, and security of data collection and transmission, and to prevent the entry of "three no" products into the market, data collection and transmission devices need to have Zhonghuan Xie certification.

The data acquisition and transmission device has automatic timing function.

The data acquisition and transmission device has a temporary storage function for data, which can be temporarily stored locally on the data acquisition device in case of network interruption. Network recovery can achieve data retransmission. The data acquisition and transmission device has a display screen function, which can view real-time data, minute data, etc. collected on site.

The data acquisition and transmission device should achieve data transmission and reverse control according to the transmission instructions, and should meet the transmission requirements for sending online monitoring data to multiple platforms.

3) Network debugging, stable data transmission

Upload data from the central monitoring platform through the on-site monitoring system, which complies with the data in the "Technical Guidelines for Online Monitoring Construction of Pollution Sources"

According to the requirements of the collection and transmission standards, the system has successfully connected to the platform and has been running continuously and stably for 168 hours.

Networking acceptance

The communication between the on-site monitoring system and the central monitoring platform is stable, eliminating communication issues such as frequent communication interruptions, data loss, and incomplete data. The online rate of the data collection and transmission system is over 90%.

Accuracy of data transmission

After the system runs stably for one week, take at least three consecutive days of data for inspection, and ensure that the data received by the upper computer is completely consistent with the data collected and stored by the data acquisition and transmission device. The relevant data reception qualification certificate shall be issued by the on duty unit of the central monitoring platform.
