Description

Technical Field

[0002] Industrial water treatment equipment, as the name suggests, is a device that degrades and purifies organic waste in wastewater through a series of physical, chemical and biological reaction methods. It is common in the field of industrial wastewater treatment technology. Since various human production activities require the participation of water, a large amount of organic wastewater will be generated in this process. If it is directly discharged without treatment, it will seriously endanger the local water source environment and cause damage to the water quality ecology. Therefore, it is necessary to use water treatment equipment to carry out a series of purification treatments on the wastewater.

[0003] After searching, it was found that a water treatment system with 4G Internet of Things function was disclosed in a utility model patent with Chinese patent publication number CN216946269U.

However, the water treatment system only has the detection function, but cannot purify the industrial wastewater in the box.

[0031] The PLC system module 3 includes a PLC master control cabinet 301, which is connected to an Ethernet module 302 via an Ethernet cable signal. The model of the Ethernet module 302 is USR-PLC100-EX24DRA, and the Ethernet module 302 is configured with a power module. The Ethernet module 302 is connected to a PLC cloud gateway 303 via a data cable signal.

The model of the Ethernet touch screen 304 is USR-HMI-107E.

[0032] according to Figure 3 and Figure 8 As shown, the industrial wastewater tank 1 is introduced into the industrial wastewater through the industrial wastewater pipeline, and then the wastewater is pumped into the neutralization tank 201 through the first pumping pump, and the water level height is detected by the photoelectric detection probe of the water level alarm, and the PH detection terminal of the PH detector detects the PH value data of the wastewater, and the water level data and the PH value data are synchronously transmitted to the PLC main control cabinet 301 and displayed by the Ethernet touch screen 304. At this time, the volume of the introduced wastewater can be calculated in combination with the volume size of the neutralization tank 201.

[0033] according to Figure 2 and Figure 3As shown, the two reagent tanks are respectively filled with an acidic neutralizer and an alkaline neutralizer through the feeding hoppers on the top, and the bottoms of the two reagent tanks are connected to the flow metering controller 203 through the first discharge pipe.

The two negative pressure fans are used to form negative pressure areas in the aeration tank 2051 and the purification box 2054, respectively, that is, clean air is introduced into the aeration tank 2051 to increase the oxygen concentration, and then the exhaust gas generated by aeration is passed into the purification box 2054, and the desulfurizer filler layer and the denitrifier filler layer in the two filter plates are used to neutralize the sulfide or nitrogen oxide exhaust gas. At the same time, a wind hole layer is provided on the inner top wall of the purification box 2054, and an activated carbon plate is provided below the wind hole layer to remove the odor of the exhaust gas.

[0036] according to Figure 4 and Figure 7 As shown, the wastewater treated by aeration in the aeration tank 2051 is sent to the filter tank 206 through the No. 4 water pipe, so that the wastewater flows through the filter plate 207 of the ultrafiltration membrane layer structure and the RO reverse osmosis membrane tube 208 respectively, and the remaining bacteria, microorganisms and small molecular organic matter in the wastewater are filtered out. The bottom of the RO reverse osmosis membrane tube 208 is fixedly connected with a drain pipe, and the drain pipe recycles the purified water. The top of the RO reverse osmosis membrane tube 208 is connected to the front of the RO flushing valve 209 through a cleaning pipe. The PLC main control cabinet 301 is used to control the RO flushing valve 209 to connect clean water to flush the RO reverse osmosis membrane tube 208 to prevent small molecular impurities from adhering and clogging, which affects the filtering effect.

[0037] In summary, the water treatment system based on the Internet of Things passes the wastewater with macromolecular impurities removed into the industrial wastewater tank 1, and then sends it into the neutralization tank 201 through the first water pump. After the pH detector detects the pH value of the wastewater, the flow metering controller 203 is used to quantitatively add the neutralizers in the two reagent tanks in the medicine storage box 202 into the neutralization tank 201, and cooperates with the stirring gear rod to fully mix and react. Then, the neutralized wastewater is passed into the aeration tank 2051 through the water inlet solenoid valve 204 for aeration treatment, thereby increasing the efficiency of aerobic bacteria in consuming the reaction organic waste. The aerated wastewater is then discharged into the filter tank 206, and the filter plate 207 of the ultrafiltration membrane structure and the RO reverse osmosis membrane tube 208 are used to remove bacterial microorganisms and small molecular organic matter in the wastewater, thereby achieving a multi-stage purification effect on the wastewater, and solving the problem that the water treatment system with 4G Internet of Things function in the above-mentioned background technology comparison document cannot perform multi-stage purification treatment on industrial wastewater.
