[0049] The drainage system control module 106 is used to control the amount of recycled water reuse based on the drainage control instruction.

[0050] The present embodiment provides a device for treating and reusing production wastewater from a sand and gravel processing system. With an intelligent analysis module and a PLC control module as the center, the device intelligently treats and reuses the wastewater generated during the production process of the sand and gravel processing system. The amount of production wastewater added and the amount of recycled water reused are adjusted at any time according to the suspended matter concentration data of the sewage treatment tank and the water volume monitoring data of the production wastewater. This improves the treatment efficiency of the production wastewater of the sand and gravel processing system, reduces the sewage treatment cost, and improves the efficiency and speed of the overall water treatment system. At the same time, it also reduces the subsequent labor burden for operators, thereby avoiding secondary pollution of production wastewater, greatly improving the environmental protection and cleanliness of the treatment and reuse device, and protecting the environment while making the treatment and reuse process of production wastewater more green and environmentally friendly.

[0051] In some optional embodiments, the intelligent analysis module 101 is specifically used to analyze the suspended matter concentration data, and determine whether the production wastewater meets the reuse standard based on the analysis results. If the production wastewater does not meet the reuse standard, the dosage and reaction time of flocculants and coagulants are determined based on the suspended matter concentration data and the production wastewater water volume monitoring data, and the dosage and reaction time of flocculants and coagulants are sent to the PLC control module 102.

[0052] Specifically, the intelligent analysis module 101 analyzes whether the production wastewater meets the reuse standard (generally required to be 100 mg / L) based on the suspended solids concentration data. If the reuse standard is not met, the intelligent analysis module 101 calculates and analyzes the suspended solids concentration data and the production wastewater water volume monitoring data to obtain the dosage and reaction time of the flocculant and coagulant aid; wherein, the calculation formula for the dosage and reaction time of the flocculant and coagulant aid is as follows:

[0053] M 助凝剂 =f 2 (Q 水 , S 1 , S 0 ) (1)

[0054] M 絮凝剂 =f 1 (Q 水 , S 1 , S 0 ) (2)

[0055] T=g(Q 水 , S 1 , S 0 , M 助凝剂 , M 絮凝剂 ) (3)

[0056] Among them, M 助凝剂 Indicates the dosage of coagulant aid, M 絮凝剂 represents the dosage of flocculant, T represents the reaction time, Q水 Indicates the amount of production wastewater, S 1 Indicates the concentration of suspended solids in production wastewater, S 0 Indicates the concentration of production wastewater that meets the standard, f 2 represents the calculation function of the amount of coagulant added, f 1 represents the calculation function of flocculant dosage, and g represents the calculation function of reaction time.

[0057] The present embodiment provides a device for treating and reusing production wastewater from a sand and gravel processing system. By judging whether the production wastewater meets the reuse standard, a preliminary judgment on the reuse of the production wastewater is achieved. Furthermore, by calculating the dosage and reaction time of the flocculant and the coagulant aid, precise control of the addition amount of the flocculant and the coagulant aid is achieved, thereby providing a guarantee for the production wastewater to meet the reuse standard.

[0058] In some optional embodiments, the PLC control module 102 is specifically used to determine the dosing control instructions based on the dosage of flocculants and coagulants and the reaction time, and send the dosing control instructions to the dosing system control module 105; wherein the dosing system control module 105 controls the addition amount of flocculants and coagulants based on the dosing control instructions.

[0060] Furthermore, the dosing system control module 105 is composed of a metering pump and a dosing motor. The metering pump adopts an electromagnetic diaphragm metering pump, which interacts with the PLC control module 102 through analog signals. The PLC control module 102 outputs a signal (i.e., a dosing control instruction) to control the dosing amount of the metering pump.

[0061] The present embodiment provides a device for treating and reusing wastewater produced by a sand and gravel processing system. The PLC control module sends a dosing control instruction to the dosing system control module to control the addition amount of flocculants and coagulants, thereby achieving accurate control of the addition amount of flocculants and coagulants.

[0062] In some optional embodiments, the intelligent analysis module 101 is also used to generate a water volume simulation signal based on the production wastewater water volume monitoring data if the production wastewater meets the reuse standard, and send the water volume simulation signal to the PLC control module 102.

[0063] Specifically, if the production wastewater meets the reuse standard, the intelligent analysis module 101 determines the drainage volume according to the production wastewater volume monitoring data, and the intelligent analysis module 101 sends a signal to the PLC control module 102, which sends an instruction to the drainage system control module 106 to control the reuse volume of recycled water; for example, the production wastewater volume monitoring data is 100m 3 , the displacement is set to no more than 100m 3 , and then according to the drainage volume, the PLC control module 102 sends instructions to the drainage system control module 106 to control the amount of recycled water reuse.

[0064] Alternatively, the intelligent analysis module 101 can obtain the water demand of the sand and gravel processing system, determine the corresponding drainage volume of the drainage system control module 106 according to the water demand of the sand and gravel processing system, and send instructions through the PLC control module to control the recycled water reuse amount of the drainage system control module 106.

[0065] This embodiment provides a device for treating and reusing production wastewater from a sand and gravel processing system. The intelligent analysis module generates a water volume simulation signal based on production wastewater volume monitoring data, and sends the water volume simulation signal to a PLC control module, thereby achieving accurate grasp of the current production wastewater volume monitoring data.

[0066] In some optional embodiments, the PLC control module 102 is further used to send a drainage control instruction to the drainage system control module 106 based on the water volume simulation signal; wherein the drainage system control module 106 controls the amount of recycled water reused based on the drainage control instruction.

[0067] Specifically, the drainage system control module 106 is composed of a flow meter and a gate control motor. The gate control motor and the flow meter control the amount of wastewater reuse. The flow meter realizes data interaction with the PLC control module 102 through analog signals. The PLC control module 102 outputs analog signals (i.e., drainage control instructions) to control the amount of recycled water reuse.

[0068] The present embodiment provides a device for treating and reusing wastewater produced by a sand and gravel processing system. The device controls the amount of recycled water reused through drainage control instructions, thereby achieving precise control of the discharge volume of the drainage system, saving water resources, improving the treatment efficiency of wastewater produced by the sand and gravel processing system, and reducing sewage treatment costs.

[0069] In some optional embodiments, the method further comprises:

[0070] The reclaimed water reuse module 107 is connected to the drainage system control module 106, and is used to store the reclaimed water discharged by the drainage system control module 106, and obtain the water demand of the sand and gravel processing system, and transmit the reclaimed water to the sand and gravel processing system based on the water demand of the sand and gravel processing system.

[0071] Specifically, Figure 4 As shown, the recycled water reuse module 107 is connected to the sand and gravel processing system to build a recycled water supply and demand platform; when the sand and gravel processing system needs water, the recycled water treated by the recycled water reuse module 107 is preferentially called; when the sand and gravel processing system temporarily does not need water, the recycled water generated by the recycled water reuse module 107 enters the recycled water storage tank for subsequent use by the sand and gravel processing system.

[0072] The present embodiment provides a device for treating and reusing wastewater produced by a sand and gravel processing system. According to the water demand of the sand and gravel processing system, treated recycled water is used preferentially, thereby realizing the distribution and utilization of recycled water, improving the utilization rate of water resources, and reducing the cost of water use.

The wastewater volume detection module monitors the wastewater volume in real time. The wastewater volume detection module calculates the corresponding water volume through water level monitoring and transmits the suspended solids concentration data and wastewater volume monitoring data to the intelligent analysis module in real time.

[0077] The intelligent analysis module analyzes whether the production wastewater meets the reuse standard based on the suspended solids concentration data. If it does not meet the reuse standard, the intelligent analysis module calculates and analyzes the suspended solids concentration data and the production wastewater volume monitoring data, adjusts the dosage of flocculants and coagulants, and the required reaction time, and transmits the dosage data and reaction time to the PLC control module, which issues instructions and transmits them to the dosing system control module;
