Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a water purification device capable of monitoring water quality in real time. Background Art

[0002] In recent years, in the field of environmental pollution control, conventional remediation technology that adds chemical substances can no longer meet the needs of complex environmental remediation such as multi-pollutants. Against this background, the biofilm remediation system came into being.

[0003] The biofilm remediation system is a technical system that uses biofilms formed by microorganisms to treat environmental pollutants or repair damaged ecosystems. Biofilm is a structure in which microbial communities are attached to solid surfaces and wrapped by extracellular polymers (EPS) secreted by themselves. These microorganisms cooperate with each other in the biofilm to degrade organic pollutants and transform harmful substances such as heavy metals, thereby achieving the purpose of repairing the environment. The biofilm remediation system consists of three parts: adsorption and enrichment of pollutants, microbial metabolic degradation, and biotransformation. When water containing pollutants flows through the biofilm, the pollutant molecules are adsorbed by the EPS and microbial cell walls on the surface of the biofilm and enriched on the surface of the biofilm. At the same time, the microorganisms on the biofilm use pollutants as carbon sources, nitrogen sources or energy sources for growth and metabolism. In this process, organic pollutants are gradually decomposed into carbon dioxide, water and simple inorganic substances. In the biofilm remediation system, microorganisms can also biotransform pollutants to achieve the purpose of degradation. The biofilm remediation system can be repaired directly at the site of pollution, avoiding the complex process of digging or extracting pollutants for off-site treatment.

[0004] Wen Yizhang et al. disclosed a device in Chinese utility model patent publication number CN219104721U for solving the error caused by sedimentation and for real-time detection of unpolluted water quality. Wu Wenhai et al. disclosed a device in Chinese utility model patent publication number CN218232126U for ultra-efficient shallow-layer flotation water purification.

[0005] Considering that traditional water purification devices often focus on post-processing of pollutants, that is, the purification process is not started until the water quality has deteriorated to a certain extent, and there is a lack of real-time control over water quality changes. This lag makes it impossible to respond effectively in time when faced with sudden pollution incidents or water quality fluctuations, resulting in the expansion of the scope of pollution and a surge in the cost of ecological restoration. Moreover, existing water quality monitoring methods mostly rely on manual regular sampling and then send it to the laboratory for analysis and testing, which not only consumes a lot of manpower, material resources and time, but also has obvious time delays in the test results, making it difficult to provide accurate basis for the real-time regulation of water purification devices. Therefore, it is very necessary to use a biofilm treatment device with real-time monitoring of water quality, which not only has important practical significance, but also has important engineering value. Summary of the invention

[0006] The present invention aims to provide a water purification device capable of monitoring water quality in real time in view of the technical defects of the prior art, so as to solve the technical problem that conventional water purification devices cannot automatically monitor water quality in real time, and thus their process measures have lags.

[0007] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0013] Preferably, the water quality monitoring system measures and stores water quality indicators at predetermined intervals, wherein the water quality indicators include water temperature, dissolved oxygen, pH, and redox potential.

[0014] Preferably, the monitor takes pictures of the interior of the body at predetermined intervals.

[0015] Preferably, the predetermined time is half an hour.

[0016] Preferably, a waterproof battery compartment is provided on the top of the device, and the waterproof battery compartment is electrically connected to the water disturbance device and the monitor respectively.

[0017] Preferably, the material of the biofilm carrier is an aerobic biofilm material, and its raw materials are polyurethane foam filler and porous spheres. The polyurethane foam filler is made by reticulating a polyurethane soft foam system containing oxidized sodium alginate powder, didecyldimethylammonium chloride and phosphoenolpyruvic acid, and the carrier surface has a wrinkled structure and a porous structure.

[0018] The present invention provides a water purification device that integrates a real-time monitoring system and a biofilm repair system, and is used for collecting water samples from a target water environment. The device is currently mainly used for the remediation of water environment pollution. After the device is put into the target water environment, it first stimulates the vibration of the water body to promote the water body to absorb oxygen, increase the dissolved oxygen content of the water body, and rapidly attach and multiply microorganisms on the carrier, forming a basis for ecological restoration. It adsorbs and reduces macromolecular organic matter and heavy metals in the water environment, especially for the current new pollutants such as microplastics and nanoparticles. It also has a good removal efficiency. The device is safe and non-toxic, and can treat water bodies for a long time. It has a very good promotion prospect for the restoration of the ecological function of water bodies.

[0019] The operation process of the present invention is as follows:

[0020] Step 1: Construction of water purification device

[0021] Considering that the suspended filler is fully fluidized in the water, the device is set to 3m×1.4m×1.2m in length×width×height. The water disturbance device is arranged at the tail of the device to provide the dissolved oxygen required for microbial degradation of pollutants and the power required for the fluidization of suspended fillers. The inlet and outlet water holes are evenly distributed on the front, back, left and right sides of the remediation system, while increasing the residence time of wastewater in the device. Solar panels and a 24-hour monitoring system are installed on the top of the device. The wireless data information transmission system adopts the WSNs system, which is an emerging system with the characteristics of low cost, simple deployment, and long data communication and transmission distance.

[0022] Step 2: Suspended filler and microbial inoculation

[0023] Aerobic biofilm material is used, and its raw materials are polyurethane foam filler and porous sphere. The polyurethane foam filler is made by reticulation of polyurethane soft foam system containing oxidized sodium alginate powder, didecyl dimethyl ammonium chloride and phosphoenolpyruvic acid, and the diameter of the sphere is 50-200mm, and the porosity is not less than 95%. The biological carrier material in the aerobic biofilm material provides sufficient space for the enrichment and growth of microorganisms, and the biological film effect is excellent, the film speed is fast, the efficiency is high, the time is short, the microbial load and adsorption capacity are large, and the microbial adhesion is good. The biofilm reactor has a short start-up time and high sewage biochemical treatment efficiency, which greatly improves the purification function of the biofilm. The equipment is put into the water area for treatment, the water body is disturbed, the water body absorbs oxygen, the dissolved oxygen of the water body is increased, and the oxygen molecules in the water are transported through all-round disturbance, including the bottom mud. Dissolved oxygen is the basic condition for maintaining the survival of aquatic microorganisms, plants and animals and the purification capacity of water bodies. After a period of time, local microorganisms continue to multiply and grow to form biofilms, which promotes the reduction of the content of pollutants in the water body.

[0024] Step 3: Pollutant degradation

[0025] During the early disturbance process, the energy released activates water molecules and generates a series of radicals, such as OH (hydroxyl), which has a strong oxidizing ability to oxidize and decompose most pollutants in water and sediment, which can greatly reduce suspended matter in water and improve water transparency. Large molecular organic pollutants are adsorbed, absorbed and decomposed by microorganisms, turning into small molecular organic matter, such as nitrogen-containing substances, which can turn into nitrogen gas and overflow from the water body, and the rest into NO 2- 、NO 3- Small molecules such as phosphorus can be absorbed and utilized by aquatic plants and animals as nutrients. Phosphorus-containing substances can also be reduced. After the macromolecular substances are digested, the suspended solids in the water will also decrease, and the transparency of the water will be improved. For inorganic compounds, such as inorganic phosphorus compounds, they can be converted into ATP and ADP and enter the organism under the action of microorganisms, which can promote the reproduction and growth of aquatic plants and animals. Microorganisms can fix, move or transform heavy metals in the soil, change their environmental chemical behavior in the soil, promote the detoxification of toxic and harmful substances or reduce their toxicity, thereby achieving the purpose of bioremediation. The principles of microbial remediation of heavy metal-contaminated soil mainly include bioenrichment (such as bioaccumulation, biosorption) and biotransformation (such as biological redox, methylation and demethylation, and dissolution of heavy metals and organic complex coordination degradation).

[0026] The present invention provides a water purification device capable of real-time monitoring of water quality. The device performs in-situ treatment based on a biofilm repair system and improves the real-time monitoring function of the water purification device. By real-time monitoring of water quality parameters, such as dissolved oxygen, pH, redox potential and other water quality indicators, the water purification device can automatically adjust the purification process according to the actual water quality conditions; in addition, by comparing the water quality data of the inlet and outlet water, it can be timely discovered whether the purification equipment has a fault or performance degradation; at the same time, after reaching a stable state, the microorganisms can be used as "biosensors" for gaseous pollutants in the environment, and the air quality can be reflected by real-time monitoring of changes in microorganisms.

[0027] In summary, the present invention can effectively solve the shortcoming of the water purification device that the target water environment water quality index cannot be monitored in real time, and can also monitor the biofilm growth state in real time to maintain high water purification efficiency. At the same time, after reaching a stable state, the microorganisms can be used as "biosensors" for gaseous pollutants in the environment, reflecting the air quality by monitoring the changes in microorganisms.
