Description

Technical Field

[0001] This invention belongs to the field of coal mine water inrush treatment technology, and relates to a deep treatment device system and treatment method for coal mine water inrush. Background Technology

[0002] With increasingly stringent requirements for the quality of coal mine water effluent, existing treatment processes are no longer limited to single technologies but rather employ a combination of technologies targeting different pollutants, exhibiting a diversified, intensive, and intelligent development trend. For example, in treating mine water containing suspended solids, traditional processes use a combination of coagulation sedimentation and filtration, which is simple and achieves a suspended solids removal rate of over 95%. For treating high-mineralized mine water, the mainstream process is a combination of ultrafiltration and reverse osmosis, which can reduce TDS (Total Dissolved Solids) to below 100 mg / L, producing high-quality water that can be recycled. For acidic mine water, limestone neutralization is generally used, while the innovative combination of biological and chemical treatment improves resource recovery rates and reduces treatment costs.

[0003] However, traditional coagulation and sedimentation processes are insufficiently adaptable to fluctuations in water quality. When influent water quality changes abruptly, problems such as poor floc settling and excessive effluent quality can easily occur. Most mine water treatment systems lack dynamic intelligent control capabilities, resulting in insufficient intelligence and difficulty in adapting to the spatiotemporal heterogeneity of water quality and quantity. Furthermore, existing mine water treatment systems still rely primarily on manual experience-based operation or simple automatic control, failing to optimize parameters such as chemical dosage and backwashing cycles in real time based on influent water quality. Therefore, how to efficiently remove pollutants from coal mine inflow water while simultaneously achieving intelligent management has become the focus of mine water treatment technology development.

[0036] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] In one specific embodiment, the present invention provides a deep treatment device system for coal mine inrush water, comprising a main control unit, a data monitoring unit, a water treatment unit, and a drainage unit. The main control unit is communicatively connected to the data monitoring unit, the water treatment unit, and the drainage unit, and is used to adjust the specific operating conditions of the water treatment unit and the drainage unit based on data feedback obtained from the data monitoring unit. The data monitoring unit includes a flow velocity detection device, a water quality detection device, and a water level detection device. The flow velocity detection device, the water quality detection device, and the water level detection device are each independently connected to the water treatment unit for online collection of coal mine inrush water condition data. Figure 1 As shown, the water treatment unit includes a water collection device 1, a buffer device 2, a multi-stage flocculation device 3, a biological filter disc 4, and a sedimentation device 5 arranged sequentially along the water flow direction to achieve deep treatment of coal mine water. The drainage unit also includes several drainage pumping components 6, which are connected to the outlet end of the sedimentation device 5 to discharge the purified clean water from the system.

[0038] In this invention, coal mine inflow refers to water that flows into the underground mining space from various water sources during the construction and production of coal mines. Coal mine inflow is characterized by complex water quality, large volume, and strong seasonality. Based on different water qualities, coal mine inflow can be categorized into clean coal mine goaf inflow, conventional component mine water, acidic mine water, high suspended solids mine water, high mineralization mine water, and mine water containing special components. Among these, clean mine water and conventional component mine water have relatively good water quality, with pollutant concentrations below environmental quality thresholds; acidic mine water has a pH less than 6 and often contains pollutants such as sulfates and heavy metals; high suspended solids mine water has a neutral pH and low mineralization, but a high proportion of fine coal and rock dust particles; high mineralization mine water is weakly alkaline or alkaline, with a mineralization greater than 1000 mg / L; mine water containing special components may include strontium, selenium, fluorine, mercury, chromium, lead, arsenic, and radioactive elements such as radium, uranium, thorium, and radon. This invention is mainly aimed at the advanced treatment of acidic mine water, mine water with high suspended solids, and mine water with high mineralization.

[0039] In some embodiments, the water collection device 1 is used to store the incoming coal mine water. It can be a water tank structure or a pool structure excavated according to local conditions. An inlet pump assembly 11 is provided at the inlet end of the water collection device 1. The inlet pump assembly 11 is communicatively connected to the main control unit, which provides feedback control over the opening and closing of the inlet pump assembly 11 and its opening degree. An inlet pipe can be provided at the inlet end of the water collection device 1, and the inlet pump assembly 11 is installed on the inlet pipe. The inlet pump assembly 11 collects water from various sources into the inlet pipe and pumps it into the water collection device 1. The inlet pump assembly 11 can be a peristaltic pump or a screw pump. Typically, an outlet pump assembly is also provided at the outlet end of the water collection device 1 to discharge the coal mine water from the water collection device 1.

[0040] The flow velocity detection device includes a first flow velocity detection component L1, located at the inlet end of the water inflow collection device 1, for monitoring the flow velocity of water entering the water inflow collection device 1. The first flow velocity detection component L1 is communicatively connected to the main control module to upload the collected data to the main control unit, which analyzes the data to determine the total water volume in the water inflow collection device 1.

[0041] The water level detection device includes a first liquid level detection component S1, which is disposed in the inner cavity of the water inflow collection device 1 for monitoring the liquid level inside the water inflow collection device 1. It is also communicatively connected to the main control module to upload the collected data to the main control unit. The main control unit analyzes the data, and when the real-time liquid level exceeds a predetermined limit, it can provide feedback control to the inlet pump component 11 and / or the outlet pump component to reduce the flow rate of coal mine water flowing into the water inflow collection device 1, thereby reducing the inflow volume and / or increasing the outflow volume from the water inflow collection device 1, ensuring that the water level inside the water inflow collection device 1 remains within a safe range.

[0042] In some embodiments, the water treatment unit further includes a water source heat pump 12, which is connected to the coal mine water collection device 1 for recovering heat from the coal mine water inflow. The water source heat pump 12 includes an evaporator, condenser, and compressor, as is well known to those skilled in the art. During application, the coal mine water inflow from the water collection device 1 enters the evaporator of the water source heat pump 12 through a pipeline, causing the refrigerant in the heat pump unit to absorb heat from the coal mine water and evaporate. The gaseous refrigerant is then compressed by the compressor, increasing its temperature and pressure. The high-temperature, high-pressure refrigerant then flows through the condenser, achieving heat transfer. The coal mine water inflow, as a low-grade heat source, can be used for production activities both underground and above ground in the coal mine.

[0043] Furthermore, the water quality testing device 9 includes an inlet water pH testing component and an inlet water hardness testing component, used to detect the pH and total hardness of the coal mine water in the water collection device 1, respectively. The inlet water pH testing component and the inlet water hardness testing component are also independently communicatively connected to the main control unit to upload the collected data. The main control unit analyzes the data; if the pH and / or total hardness exceed predetermined limits, it controls the disconnection between the water collection device 1 and the water source heat pump 12, stopping heat recovery and directly sending the coal mine water into the buffer device 2 to avoid damaging the heat pump equipment.

[0044] In some embodiments, the buffer device 2 includes at least two buffer bodies 21, which are independently connected to the water inflow collection device 1, allowing adjustment of the communication between the water inflow collection device 1 and different buffer bodies 21. The number of buffer bodies 21 can be 2, 3, 4, 5, 6, 7, or 8, etc. Along the flow direction of the coal mine water inflow, the volume of at least two buffer bodies 21 gradually decreases. Preferably, the volume of the preceding buffer body 21 is 1.2 to 2.0 times the volume of the following buffer body 21.

[0045] Taking the buffer device 2, which includes three buffer bodies 21, as an example, denoted as the first buffer body, the second buffer body, and the third buffer body, their volumes decrease sequentially. The water collection device 1 is connected to the first buffer body, the second buffer body, and the third buffer body. The main control unit can control the connection between the water collection device 1 and the different buffer bodies 21 based on the total inflow water volume. For example, when the total water volume is large, the main control unit controls the connection between the water collection device 1 and the first buffer body; when the total water volume is small, the main control unit controls the connection between the water collection device 1 and the second buffer body or the water collection device 1 and the third buffer body.

[0046] An overflow outlet is provided between two adjacent buffer bodies 21. When the total water volume exceeds the volume of the first buffer body 21, it can flow into the second or even the third buffer body 21 through the overflow outlet to cope with flooding, seasonal changes or sudden water surges.

[0047] Specifically, a first electrically controlled valve k1 is provided on the connecting pipeline between the buffer body 21 and the water collection device 1, and a second electrically controlled valve k2 is provided at the outlet end of each buffer body 21. The first electrically controlled valve k1 and the second electrically controlled valve k2 are independently communicatively connected to the main control unit. The main control unit realizes feedback control of the buffer body 21 by switching the opening and closing of the first electrically controlled valve k1 and the second electrically controlled valve k2 of different buffer bodies 21.

[0048] The flow rate detection device also includes a second flow rate detection component L2, which is located at the inlet end of the buffer device 2. It is used to detect the flow rate of the water entering the buffer device 2 and upload it to the main control unit. The main control unit analyzes the data to provide feedback control on the opening degree of the first electrically controlled valve k2.

[0049] The water quality testing device 9 includes several first pH testing components, several first hardness testing components, several first TDS testing components, and several first metal ion concentration testing components. These components are independently installed within the buffer body 21 of the buffer device 2, and are used to detect the pH value, total hardness, TDS concentration, and metal ion concentration of the influent, respectively, and upload the data to the main control unit. The main control unit analyzes the data to determine the pollution level of the influent, and uses this information to control the operation of the multi-stage flocculation device 3.

[0050] The water level detection device further includes several second liquid level detection components S2. Each second liquid level detection component S2 is disposed within the inner cavity of the buffer body 21 of the buffer device 2 and is used to monitor the liquid level within the buffer body 21. The second liquid level detection components S2 are also communicatively connected to the main control module to upload the collected data to the main control unit. The main control unit analyzes the data, and when the real-time liquid level exceeds a predetermined limit, it can provide feedback control to the opening degree of the first solenoid valve k1 and the second solenoid valve k2, or open the next buffer body 21 to divert excess coal mine water into an adjacent buffer body 21, thereby maintaining the liquid level within a safe range.

[0051] In some embodiments, the multi-stage flocculation device 3 includes at least two flocculation bodies 31 connected sequentially along the flow direction of the coal mine water, used to remove suspended solids, emulsified oil, and heavy metal ion pollutants adsorbed on suspended particles from the coal mine water. The inlet end of each flocculation body 31 is connected to the outlet end of the buffer device 2, allowing adjustment of the connection between the buffer device 2 and different flocculation bodies 31. The number of flocculation bodies 31 can be 2, 3, 4, 5, 6, 7, or 8, etc.

[0052] Specifically, a flocculation pump assembly and a third electrically controlled valve k3 are installed on the connecting pipeline between the flocculation body 31 and the buffer body 31 of the buffer device 2. The third electrically controlled valve k3 and the flocculation pump assembly are independently communicatively connected to the main control unit, which is used to provide feedback control on the opening and closing of the flocculation pump assembly and the opening degree of the third electrically controlled valve k3. Furthermore, the inlet end of each flocculation body 31 is independently connected to all buffer bodies 21 of the buffer device 2. Taking the multi-stage flocculation device 2 comprising three flocculation bodies 31 as an example, they are respectively referred to as the first flocculation body, the second flocculation body, and the third flocculation body. The first flocculation body is connected to the first buffer body, the second buffer body, and the third buffer body, and a flocculation pump assembly and a third electrically controlled valve k3 are installed on the connecting pipeline. The second flocculation body is connected to the first buffer body, the second buffer body, and the third buffer body, and a flocculation pump assembly and a third electrically controlled valve k3 are installed on the connecting pipeline. Simultaneously, the third flocculation body is connected to the first buffer body, the second buffer body, and the third buffer body, and a flocculation pump assembly and a third electrically controlled valve k3 are installed on the connecting pipeline. The main control unit provides feedback control over the opening and degree of the flocculation pump assembly and the third electrically controlled valve k3 on the connecting pipelines of different flocculation bodies 31 and buffer bodies 21 to adapt to different water quality conditions.

[0053] In some embodiments, the multi-stage flocculation device 3 further includes several dosing components 32, which are connected to and connected to the flocculation body 31. A dosing pump assembly and a fifth electrically controlled valve k5 are installed on the connecting pipeline between the dosing components 32 and the flocculation body 31. The dosing pump assembly and the fifth electrically controlled valve k5 are independently communicatively connected to the main control unit, which is used to provide feedback control on the opening and closing of the dosing pump assembly and the opening degree of the fifth electrically controlled valve k5. The flocculants used in this invention include, but are not limited to, polyaluminum chloride, polyferric sulfate, polyaluminum ferric chloride, anionic polyacrylamide, and chitosan. The dosage is precisely controlled according to different influent water quality conditions and the water volume in each flocculation body 31, ensuring flocculation effect while avoiding material waste.

[0054] Specifically, the flow rate detection device also includes a sixth flow rate detection component L6, which is located at the outlet end of the dosing component 32 of the multi-stage flocculation device 3. The main control unit controls the opening and closing and the degree of opening of the sixth flow rate detection component L6 based on the water quality in the buffer device 2, thereby adjusting the dosage.

[0055] The water level detection device further includes several third liquid level detection components S3. Each third liquid level detection component S3 is disposed within the inner cavity of the flocculation body 31 of the multi-stage flocculation device 3, and is used to monitor the liquid level within the flocculation body 31. The third liquid level detection components S3 upload the detected liquid level data to the main control unit. The main control unit analyzes the data and provides feedback to control the inflow and / or outflow of water into the flocculation body 31 to ensure the liquid level remains within a safe range.

[0056] In some embodiments, microorganisms and fungi that can adsorb heavy metal ions grow on the packing material of the biofilter disc 4, trapping heavy metal ions in the gushing water within the filter layer. For example, iron-manganese oxidizing bacteria dissolve or convert iron and manganese ions. The inlet end of the biofilter disc 4 is connected to the outlet end of the last flocculation body 31 and the outlet end of the sedimentation device 5, respectively, to further treat the water discharged from the flocculation device 3. Simultaneously, it can treat water whose quality still does not meet requirements after treatment by the sedimentation device 5. In addition, the biofilter disc 4 also includes necessary pipelines, conventional valves, and general-purpose pumps for complete process implementation. However, the above content is not the main inventive point of this invention, and those skilled in the art can add layouts based on the process flow and equipment structure selection. Specifically, a filter disc inlet pump and a filter disc outlet pump are respectively installed at the inlet and outlet ends of the biofilter disc 4, and the filter disc inlet pump and filter disc outlet pump are independently communicatively connected to the main control unit for remote control.

[0057] Furthermore, a sixth electrically controlled valve k6 is installed on the connecting pipe between the inlet end of the biological filter plate 4 and the outlet end of the sedimentation device 5. The sixth electrically controlled valve k6 is communicatively connected to the main control unit. The main control unit adjusts the opening and closing of the sixth electrically controlled valve k6 to return the sedimented water to the biological filter plate 4 and further adjust its water volume.

[0058] The flow rate detection device also includes a third flow rate detection component L3, located at the inlet end of the biofilter disc 4, for collecting influent flow rate data. The third flow rate detection component L3 is communicatively connected to the main control unit, uploading the collected data to the main control unit. The main control unit then adjusts the influent and effluent flow rates of the biofilter disc 4 to ensure the water volume remains within the manageable capacity of the microorganisms and fungi within the biofilter disc 4. Specifically, based on the influent flow rate data, the main control unit can control the power of the filter disc influent pump and filter disc effluent pump, thereby regulating the influent and effluent flow rates.

[0059] In some embodiments, the sedimentation device 5 is used to further remove suspended solids in the effluent, as well as bacterial flocs and insoluble precipitates discharged from the biological filter disc. The sedimentation device 5 can be a horizontal flow sedimentation tank, a vertical flow sedimentation tank, a radial flow sedimentation tank, an inclined plate sedimentation tank, etc., and the present invention does not specifically limit it in this regard.

[0060] In some embodiments, the outlet of the sedimentation device 5 is connected to a drainage unit to discharge the treated clean water. Simultaneously, it is also connected to the inlet of each of the flocculants 31 to return water that does not meet the water quality requirements to the flocculants 31 for repeated treatment. According to the effluent quality of the sedimentation device 5, the present invention returns water that does not meet the requirements to different flocculants 31. For example, when the effluent pollutant level of the sedimentation device 5 is level one, it can be directly fed to the drainage unit; when the effluent pollutant level of the sedimentation device 5 is level two, the effluent is returned to the inlet of the last flocculant 31; when the effluent pollutant level of the sedimentation device 5 is level three, the effluent is returned to the inlet of the second flocculant 31; and when the effluent pollutant level of the sedimentation device 5 is level four, the effluent is returned to the inlet of the first flocculant 31.

[0061] Specifically, a fourth electrically controlled valve k4 is provided on the connecting pipe between each of the flocculants 31 and the sedimentation device 5. The fourth electrically controlled valve k4 is communicatively connected to the main control unit. The main control unit remotely controls the opening and closing of the fourth electrically controlled valve k4 and the opening degree to realize the adjustment of the effluent return flow and the return flow rate.
