[0002] With the exploitation of coal resources, the amount of mine water produced is increasing. Mine water usually contains suspended matter, organic matter, and heavy metal ion pollutants. If it is discharged directly, it will not only cause a waste of water resources, but also cause serious pollution to the environment. Therefore, it is of great significance to deeply treat mine water to meet the reuse or discharge standards.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] Reference Figure 1-Figure 7 , In the first embodiment of the present invention, the present invention provides a mine water deep treatment system, including: a pretreatment module, a primary treatment module, a secondary treatment module, a deep treatment module and a disinfection reuse module;

[0041] The pre-treatment module is used to remove large-sized debris and balance water quality and quantity;

[0042] The primary treatment module is used to form flocs and precipitate and remove suspended matter and some organic matter in the mine water;

[0043] The secondary treatment module is used to remove macromolecular organic matter, colloidal substances, bacteria and viruses;

[0044] The deep treatment module is used to efficiently remove dissolved salts, small molecular organic matter and various ions;

[0045] The disinfection and reuse module is used for disinfection and sterilization to ensure the safety of reuse and to store qualified reused water for reuse.

[0046] The pretreatment module includes a screen well, an adjusting tank and a primary sedimentation tank. The screen well is used to intercept large-sized debris, the adjusting tank is used to balance the water quality and quantity, and reduce the impact of fluctuations in mine water quality and quantity on subsequent treatment processes. The primary sedimentation tank is used for preliminary sedimentation to remove larger particles of suspended matter and some sediment.

[0047] The primary treatment module includes a coagulation reaction tank and a sedimentation tank. The coagulation reaction tank is used to mix coagulants and coagulant aids with suspended matter and some organic matter in the water to form larger flocs. The sedimentation tank is used to settle the flocs formed by the coagulation reaction to further remove suspended matter and some organic matter in the water.

[0048] The secondary treatment module includes an ultrafiltration device, a reverse osmosis device and a concentrate tank. The ultrafiltration device is used to remove macromolecular organic matter and colloidal substances in mine water. The reverse osmosis device is used to remove soluble salts and small molecular organic matter in mine water. The concentrate tank is used to store the concentrate produced by the reverse osmosis device.

[0049] The deep treatment module includes an ultraviolet sterilizer and an activated carbon adsorption tower. The ultraviolet sterilizer is used to kill bacteria, viruses and microorganisms in the water. The activated carbon adsorption tower is filled with activated carbon to absorb odor, trace organic matter and residual heavy metal ions in the water.

[0050] The disinfection and reuse module includes a disinfection tank and a reuse water tank. The disinfection tank is used to disinfect and sterilize the treated mine water, and the reuse water tank is used to store the disinfected reuse water and transport it to the water use point.

[0051] The pretreatment module provides stable water inlet conditions for subsequent treatment, which helps to improve treatment efficiency and effectiveness, reduce treatment instability caused by fluctuations in water quality and quantity, and the primary sedimentation tank initially precipitates larger suspended matter and some silt, effectively reducing the load of subsequent treatment units and improving overall treatment capacity.

[0052] In the primary treatment module, the coagulation reaction tank allows the coagulant and coagulant aid to fully mix with the pollutants to form flocs, increasing the particle size of the pollutants to facilitate subsequent sedimentation and removal. The sedimentation tank separates the flocs and further removes suspended matter and some organic matter, significantly improving water quality and laying a good foundation for subsequent deep treatment.

[0053] The ultrafiltration device of the secondary treatment module can efficiently remove large molecular organic matter and colloidal substances, improving the purity of water quality. The reverse osmosis device can deeply remove soluble salts and small molecular organic matter, making the effluent quality reach higher standards. The concentrate tank stores the concentrate produced by reverse osmosis for subsequent centralized treatment or reuse, reducing the impact on the environment.

[0054] The ultraviolet sterilizer of the deep treatment module uses the strong penetrating power and bactericidal effect of ultraviolet rays to quickly and efficiently kill all kinds of bacteria, viruses and microorganisms in the water, ensuring the biological safety of the water quality. The activated carbon in the activated carbon adsorption tower absorbs odors, trace organic matter and residual heavy metal ions, further improving the water quality and making it fresher and harmless.

[0055] The disinfection pool of the disinfection and reuse module thoroughly disinfects and sterilizes the treated mine water, eliminating potential health risks and ensuring safe reuse. The reuse water pool stores the disinfected and qualified reuse water and delivers it accurately to the water use point through the conveying system, realizing the recycling of water resources, saving water resources and reducing water costs.

[0056] Embodiment 2:

[0057] Reference Figure 1-Figure 7 In a second embodiment of the present invention, the present invention provides a method for deep treatment of mine water, the method comprising:

[0058] Step 1: The mine water first enters the pretreatment module, passes through the screen well, intercepts debris larger than 10-20 mm in size, and then enters the regulating tank. The liquid level sensor and stirring device are used to balance the water quality and quantity, and then enters the primary sedimentation tank. The mud hopper and mud pump at the bottom of the tank discharge large suspended solids and some sediment sediments;

[0059] Step 2: The pretreated mine water flows into the primary treatment module. In the coagulation reaction tank, according to the online monitoring of pH value and turbidity instrument data, appropriate amount of coagulant and coagulant aid are added. After being fully stirred by multiple stirring paddles, it enters the sedimentation tank and uses the inclined tube sedimentation structure to accelerate the floc sedimentation and separation. The treated water enters the intermediate water tank and is monitored by the lifting pump and water quality monitoring probe, ready to enter the secondary treatment module;

[0060] Step 3: The water in the intermediate pool enters the ultrafiltration device of the secondary treatment module, using an external pressure ultrafiltration membrane assembly whose membrane material is polyvinylidene fluoride and whose membrane pore size is 0.01-0.1 μm. Under the protection of the backwash system and chemical cleaning system, macromolecular organic matter and colloidal substances are removed;

[0061] Step 4: The effluent from the ultrafiltration device enters the activated carbon adsorption tower, and the adsorption performance of the activated carbon is used to further remove organic matter, odor and some heavy metal ions in the water. The water treated by the activated carbon adsorption tower enters the reverse osmosis device of the deep treatment module, and the spiral reverse osmosis membrane element is used. The membrane material is aromatic polyamide. Under the synergistic effect of the high-pressure pump, energy recovery device and antiscalant dosing system, the soluble salts, small molecular organic matter and various ions are efficiently removed;

[0062] Step 5: The effluent from the reverse osmosis device enters the disinfection tank of the disinfection and reuse module, and is disinfected and sterilized by ultraviolet light or chlorine dioxide under the control of the disinfection dosage control device. The disinfected water enters the reuse water tank and is reused through the overflow port and the reuse pump to achieve the reuse of qualified water.

[0063] Chlorine dioxide disinfection methods include:

[0064] First, a chlorine dioxide solution of a certain concentration is prepared by a chlorine dioxide generator, and then the chlorine dioxide solution is accurately added to the disinfection pool using a metering pump;

[0065] In the disinfection tank, the chlorine dioxide solution is fully mixed with the mine water. The chlorine dioxide molecules can quickly diffuse into the water and come into contact with the microorganisms in the water;

[0066] Keep the mine water in the disinfection tank for 15 to 30 minutes to ensure that the chlorine dioxide has sufficient contact time with the mine water.

[0067] In the pretreatment process of step one, the interception function of the screen well is crucial. It can effectively block large debris and prevent it from entering the subsequent treatment link, thereby avoiding blockage and damage to the treatment equipment. The liquid level sensor in the regulating tank accurately monitors the water level in real time, and the stirring device ensures that the water quality is evenly mixed, making the subsequent treatment more stable and efficient. The sludge bucket and sludge pump of the primary sedimentation tank work together to discharge the precipitated impurities in time, ensuring the continuous and effective operation of the primary sedimentation tank.

[0068] In step two, the online monitoring instrument in the coagulation reaction tank feeds back water quality data in real time, providing a scientific basis for the precise addition of coagulants and coagulant aids to ensure that the reaction proceeds fully. The strong stirring of multiple agitators fully mixes the reagents and sewage, improving the reaction efficiency. The inclined tube sedimentation structure of the sedimentation tank increases the sedimentation area, accelerates the sedimentation and separation of flocs, and improves the sedimentation effect. The lifting pump and water quality monitoring probe in the intermediate water tank work closely together to accurately control the water flow and water quality, making full preparations for entering secondary treatment.

[0069] In step three, the external pressure ultrafiltration membrane component of the ultrafiltration device has high-efficiency separation performance and can accurately intercept large molecular organic matter and colloidal substances. The backwash system and chemical cleaning system regularly clean and maintain the membrane component to extend the service life of the membrane component and ensure the long-term stable operation of the ultrafiltration device.

[0070] In step four, the activated carbon in the activated carbon adsorption tower has a rich pore structure and a huge specific surface area, which can deeply adsorb organic matter, odor and some heavy metal ions in the water, further improving the water quality. The rolled reverse osmosis membrane element of the reverse osmosis device has the characteristics of high selectivity and high flux. Under the synergistic effect of the high-pressure pump, energy recovery device and antiscalant dosing system, efficient separation and purification are achieved to ensure that the effluent water quality meets high standards.

[0071] In step five, the ultraviolet disinfection method used in the disinfection pool is fast, efficient, and has no secondary pollution. It can quickly kill microorganisms in the water. The disinfection dosage control device accurately controls the dosage of the disinfectant to ensure the disinfection effect while avoiding excessive use of the agent. The overflow port and reuse pump of the reuse water pool are reasonably designed, which can stably store and transport qualified reuse water to meet different reuse needs.

[0072] For chlorine dioxide disinfection, the concentration of the solution prepared by the chlorine dioxide generator is stable and reliable, which provides a guarantee for the disinfection effect. The precise addition of the metering pump ensures the uniform distribution of chlorine dioxide in the disinfection tank. In the disinfection tank, the chlorine dioxide molecules have sufficient contact and sufficient contact time with the microorganisms, making the disinfection process more thorough, effectively killing various harmful microorganisms and ensuring the safety of reuse.
