Description

Technical Field

[0001] This utility model belongs to the field of wastewater discharge monitoring technology, specifically a multi-plant wastewater monitoring system. Background Technology

[0002] Industrial wastewater is generated during the production processes of food processing and other enterprises. To monitor wastewater quality, companies typically set up wastewater monitoring stations equipped with COD (Chemical Oxygen Demand) monitoring equipment. The power cord of a sampling pump is connected to this equipment. The COD monitoring equipment outputs a sampling signal, controlling the pump to start and transport wastewater from the sewage pipeline to the monitoring station. However, due to factory layout limitations, the power cord of the sampling pump, located far from the monitoring point, often needs to cross roads or other buildings. This is typically done by running the cord through the sewage pipeline to the COD monitoring equipment. Prolonged immersion of the wiring in wastewater can cause liquid to seep into the insulation, leading to short circuits and electrical leaks. In severe cases, this can result in electric shock or damage to equipment. Utility Model Content

[0003] The purpose of this invention is to provide a multi-plant wastewater monitoring system to avoid the sampling pump power line being submerged in the wastewater pipe for a long time, thereby enabling multi-plant wastewater monitoring.

[0004] To achieve the above objectives, the technical method adopted by this utility model is as follows: A multi-plant wastewater monitoring system includes a wastewater monitoring station, which is equipped with a wastewater monitoring device and a wireless transmitter, which are electrically connected. Each plant area is equipped with a wastewater sampling tank, and each sampling tank is connected to a sampling pump, which is connected to the wastewater monitoring device. Each plant area has a control box installed in its power supply area, which contains a sampling pump start / stop controller and a wireless receiver, which are electrically connected to the sampling pump start / stop controller. The sampling pump start / stop controller is also electrically connected to the sampling pump in the corresponding plant area. Each plant area's wireless receiver is communicatively connected to the wireless transmitter, and each plant area's wireless receiver has a unique logical address.

[0005] As a limitation, the wastewater monitoring device shall use an online COD water quality monitoring device.

[0006] The beneficial effects achieved by this utility model, due to the adoption of the above-mentioned solution, compared with the prior art, are as follows: This utility model provides a multi-plant wastewater monitoring system that transmits the sampling signal output by the wastewater monitoring device to the sampling pump start / stop controller via a wireless transmitter and receiver, thereby controlling the start and stop of the sampling pump. This avoids the sampling pump power line being submerged in the wastewater pipe for a long time, eliminates the risk of leakage and short circuit, improves the safety of the system, prevents electric shock accidents and equipment damage, and realizes multi-plant wastewater monitoring.

[0007] This invention is applicable to wastewater monitoring in multiple plant areas. Attached Figure Description

[0011] A multi-plant wastewater monitoring system, such as Figure 1 As shown, the system includes a wastewater monitoring station, which is equipped with a wastewater monitoring device and a wireless transmitter, which are electrically connected. Each plant area has a wastewater sampling tank, and each sampling tank is connected to a sampling pump via a pipeline. The sampling pump is connected to the wastewater monitoring device via a pipeline. Each plant area has a control box installed in its power supply area. The control box contains a sampling pump start / stop controller and a wireless receiver, which are electrically connected to the sampling pump start / stop controller. The sampling pump start / stop controller is also electrically connected to the sampling pump in the corresponding plant area. Each plant area's wireless receiver is communicatively connected to the wireless transmitter, and each plant area's wireless receiver has a unique logical address.

[0012] In this embodiment, the wastewater monitoring device adopts an online COD water quality monitoring device, and the wireless transmitter and receiver adopt the Siwei Wireless SK200pro single-channel wireless switch control module.

[0013] In this embodiment of the multi-plant wastewater monitoring system, the wastewater monitoring device outputs a sampling signal for a certain plant area. The sampling signal is transmitted to a wireless receiving device via a wireless transmitter. The wireless receiving device transmits the received sampling signal to the sampling pump start / stop controller. The sampling pump start / stop controller controls the sampling pump to start according to the sampling signal. The wastewater from the wastewater sampling pool of the corresponding plant area is transported to the wastewater monitoring device for water quality testing via the sampling pump.
