[0002] Comprehensive ecological improvement is a comprehensive method of environmental protection and ecological restoration, which aims to improve polluted and damaged natural ecosystems and achieve ecological balance and sustainable development. It is usually applied to areas that are greatly affected by human activities, such as industrial areas, agricultural areas, urban areas, etc., to improve the local ecological environment.

[0003] Traditional remediation systems usually rely on a single treatment method, such as physical sedimentation or basic biological treatment, which is not efficient in removing dissolved organic matter, fine particles or special chemicals. Secondly, traditional methods require aeration or heating steps, which leads to increased operating costs and increased environmental burdens. They also lack adaptability to water quality fluctuations and complex sewage compositions, making it difficult to cope with the changing composition of industrial wastewater or the increased pollution load of urban sewage.

[0004] Therefore, a method of ecological comprehensive remediation system based on environmental protection water treatment technology is proposed. Summary of the invention

[0031] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0032] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0033] like Figure 1-5 As shown, the embodiment of the present invention provides a method for an ecological comprehensive improvement system based on environmental protection water treatment technology, including:

[0034] Multi-layer biofiltration modules, each equipped with a microbial community to remove different types of water pollutants;

[0035] The multi-level biofiltration module is a vertically stacked structure that supports the weight of the entire filtration system by building a foundation platform that is sufficiently load-bearing.

[0036] Installation of the first layer (coarse particle removal layer): install the frame of the first layer on the base platform, fill the filter medium of the first layer, and add the microbial community that degrades macromolecular organic matter;

[0037] Installation of the second layer (fine particles and partially dissolved matter removal layer): install the frame of the second layer on top of the first layer, fill it with the filter medium of the second layer, and inject the microbial community for the degradation of small molecular organic matter;

[0038] Installation of the third layer (dissolved organic matter and nutrient removal layer): The frame of the third layer is installed on top of the second layer, filled with filter media, and added with microbial communities for dissolved organic matter degradation and nutrient removal;

[0039] First layer - coarse particle removal: The bottom layer is used to remove larger suspended particles and organic matter. This layer uses a larger pore size filter medium to reduce clogging and allow larger particles to remain. The microbial community in this layer mainly includes microorganisms that can survive in a rough environment and decompose large molecular organic matter;

[0040] Its structure is mainly made of stainless steel frame to support the weight and water pressure of the upper layer. The filter medium is coarse sand or pebbles, and the particle size is generally between 2 and 10 mm. It is used to intercept large particles of pollutants and suspended solids, and the surface for microorganisms to attach to provides attachment points for microorganisms to decompose these larger organic matter, and intercept and remove larger particles in the water, such as mud, fallen leaves, and larger organic fragments.

[0041] Second layer - fine particles and partially dissolved matter removal: The middle layer is designed to process smaller suspended matter and partially dissolved organic matter. The filter media in this layer is finer to improve the capture capacity of fine particles. In this layer, the selected microbial community has a higher metabolic rate and the ability to degrade small molecular organic matter.

[0042] Its structure is similar to the first layer, with a finer grid to support finer filter media. The filter media mainly include fine sand and specially made porous materials of biological ceramsite. The particle size is usually between 0.5 and 2 mm. The surface is treated with microporous design to promote the growth of microorganisms. It is aimed at the removal of medium-sized suspended solids and some soluble organic matter, and promotes the growth and activity of microorganisms.

[0043] The third layer - dissolved organic matter and nutrient removal: The top layer is used to remove dissolved organic matter and nutrients. This layer uses finer filter materials to provide a larger surface area for microorganisms to attach. Nitrifying bacteria, denitrifying bacteria and phosphorus accumulating microorganisms are selected to effectively decompose dissolved organic matter and remove nitrogen and phosphorus through absorption and metabolic processes;

[0044] It adopts a precise frame structure to ensure the finest filtration and good water flow distribution. The filter medium mainly includes activated carbon, highly absorbent polymer, highly porous material with high specific surface area, and the design of biocompatible coating promotes the optimal growth of microorganisms.

[0045] The natural ecological purification park is equipped with a variety of wetland plants and microbial communities to remove nutrients and organic matter from the water. The natural ecological purification park adopts a modular design. Each module automatically adjusts the combination of wetland plants and microbial communities according to water quality monitoring data to adapt to different water quality conditions;

[0046] It adopts the configuration of shallow water area module, deep water area module and staggered vegetation area module;

[0047] The shallow water module is a shallow wetland with a water depth usually maintained at 30 to 60 cm. The ground is paved with permeable but stable fine sand and gravel to support the growth of plant roots and microorganisms. Reeds with strong roots are used to absorb nitrogen, phosphorus and other nutrients in the water. Water hyacinth is used to absorb soluble pollutants and provide microbial attachment points. Nitrifying bacteria and denitrifying bacteria are introduced for the biological transformation of ammonia nitrogen. Rhizosphere microorganisms are combined to utilize plant root secretions to enhance the degradation of organic matter. Slow-flowing water is used to ensure sufficient contact time to promote the absorption and degradation of nutrients.

[0048] The water depth of the deep water module is set at 1 to 2 meters. A deep water area and a shallower edge area are set up, and a plastic film is laid on the bottom to prevent water bodies from penetrating into the soil. The fixed organisms are lotus, whose roots are stable in the deep water area and can absorb soluble pollutants. The floating organisms are duckweed, which covers the water surface, reduces the growth of algae, and absorbs pollutants in the water. The organic pollutants in the deep water area are treated by methane-producing anaerobic microorganisms, which work synergistically with the plant roots to improve the degradation efficiency of organic matter.

[0049] The staggered vegetation zone module combines shallow and deep water areas to form a diverse water environment. Aquatic plant areas, floating bed areas and submerged plant areas are set up in this environment. Cattails and water celery are used as fixed plants to adapt to diverse water depths, promote physical filtration and biodegradation, and water lilies and aquatic ferns are used as floating plants to increase water surface coverage and control algae growth. By combining aerobic and anaerobic microorganisms to adapt to different redox conditions, biofilms are formed around plant roots to improve the removal efficiency of pollutants.

[0050] Water quality monitoring sensors are arranged throughout the natural ecological purification park. The sensors are installed at the water inlet, outlet and the central area of ​​each module to monitor the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) in real time: reflecting the degree of organic pollution in the water body, total nitrogen and total phosphorus: indicating the level of nutrients, too high will lead to algal blooms, dissolved oxygen (DO): assessing the redox state in the water body, pH value: affecting microbial activity and chemical treatment processes, turbidity: reflecting the content of suspended particles in the water. Under normal circumstances, the data is automatically updated every 15 to 30 minutes; in the event of extreme weather or suspected pollution incidents, the collection frequency is increased to respond in real time;

[0051] Its adjustment:

[0052] Automatically adjust the water flow into different modules according to COD, BOD and nutrient levels, and control the water flow to the areas that need treatment most by adjusting the gate position and pump speed;

[0053] If data show a decrease in efficiency of a treatment stage (e.g., insufficient nitrogen removal), enhance the treatment capacity of that stage by adding or activating microorganisms and, if necessary, adding plants that are more effective against pollutants, depending on water quality;

[0054] In deep water modules, water depth is adjusted according to dissolved oxygen and organic matter load to optimize microbial activity under anaerobic conditions, and in shallow water and interlaced vegetation areas, flow rate is adjusted according to nitrogen and phosphorus removal requirements to ensure sufficient contact time.

[0055] Through the joint work of these three modules, a diverse ecology is formed, which not only effectively removes nutrients and organic matter from the water, but also provides biodiversity and beautifies the environment. Through monitoring data and adjustments, it is ensured that the ecological purification park can efficiently remove various pollutants while adapting to environmental changes and water quality fluctuations.

[0056] Microbial electrolysis cells, which are equipped with highly conductive materials as electrodes and use electroactive microorganisms for organic matter decomposition and electrical energy recovery;

[0057] The electrode is made of graphene composite material, which has extremely high conductivity and chemical stability. The high specific surface area of ​​graphene provides a large number of microbial attachment points, increases the contact area between microorganisms and electrodes, and thus improves the efficiency of electrical energy recovery. Electroactive microorganisms are used in MEC, which can directly convert organic matter into electrical energy under anaerobic conditions. Through their metabolic processes, microorganisms convert organic matter in wastewater into electrons and transfer them to the anode. At the anode, electroactive microorganisms oxidize organic matter, releasing electrons and protons. Electrons flow through the circuit to the cathode, while protons migrate through the solution. At the cathode, electrons, protons and oxygen react to produce water.

[0058] The physical adsorption and precipitation unit uses porous high adsorption materials to remove tiny suspended particles and soluble pollutants. The physical adsorption and precipitation unit is configured as a series of adsorption chambers, each of which is filled with adsorption materials. Water flows through the adsorption chambers in turn to ensure full contact with the adsorption materials. The adsorption materials used in the physical adsorption and precipitation unit are porous activated carbon and modified zeolite. Activated carbon with high specific surface area can effectively adsorb organic matter and certain inorganic matter in water. Modified zeolite is suitable for removing ammonia nitrogen and heavy metal ions in water, thereby improving the removal efficiency of soluble pollutants and tiny suspended particles.

[0059] The water body first enters the sedimentation area, and the slow water flow is conducive to the sedimentation of suspended particles. The water after preliminary sedimentation flows into the adsorption cabin, ensuring that the fine particles and soluble pollutants in the water body can fully contact with the adsorption material. The water flows through the cabin filled with activated carbon and modified zeolite, and captures and adsorbs tiny pollutant particles and soluble substances through the surface and internal pore structure of the materials. The activated carbon is mainly responsible for the removal of organic matter, while the modified zeolite is more effective in removing inorganic ions. The physical adsorption and precipitation units can effectively remove tiny suspended particles and soluble pollutants, significantly improving the effluent quality.

[0060] In this comprehensive water treatment system, multi-level biological filtration modules, natural ecological purification parks, microbial electrolysis cells, and physical adsorption and precipitation units work together to form a complete water treatment process:

[0061] (1) Initial treatment stage: The multi-level biological filtration module is the first stage of water treatment, mainly used to remove suspended solids, macromolecular organic matter and some nutrients (nitrogen and phosphorus) in water;

[0062] Each filter module has a type of pollutant setting to ensure that large particles and primary pollutants are effectively removed. After preliminary treatment, the water quality is improved, and most large particle pollutants and some dissolved organic matter are removed;

[0063] (2) Intermediate treatment stage: After multi-level biological filtration, the water flows into the natural ecological purification park. In this stage, dissolved organic matter, nitrogen, phosphorus and other nutrients are further removed through ecological methods. Plants and microorganisms work together in this stage. Through the treatment of the natural ecosystem, the organic matter and nutrients in the water body are effectively degraded and removed, improving the ecological quality of the water body and increasing biodiversity.

[0064] (3) Advanced treatment stage: The water purified by natural ecology flows into the microbial electrolysis pool, where the electroactive microorganisms use organic matter to generate electric current, further degrading the remaining organic matter;

[0065] (4) Final fine treatment stage: After the first three stages of treatment, the water quality has been significantly improved. Finally, the water flows into the physical adsorption and precipitation unit for final fine treatment. In this stage, activated carbon and modified zeolite remove tiny suspended particles and remaining dissolved pollutants;

[0066] The entire system gradually deepens the degree of water treatment through multiple staged treatment modules, from physical filtration to biodegradation, to electrochemical treatment, and finally to fine purification through physical adsorption and precipitation. The multi-stage treatment method not only improves the efficiency and effectiveness of water treatment, but also ensures the overall improvement of water quality and adapts to different treatment needs and environmental standards.

[0067] In this comprehensive water treatment system, through the different organic combinations of multi-level biological filtration modules, natural ecological purification parks, microbial electrolysis cells, and physical adsorption and precipitation units, specific effects are achieved:

[0068] Combination 1: Multi-level biological filtration module + natural ecological purification park

[0069] Primary treatment: The water first passes through a multi-level biological filtration module to remove large particle pollutants and some dissolved organic matter;

[0070] Intermediate treatment: It then flows into the natural ecological purification park, where dissolved organic matter and nutrients are further removed through the synergistic action of plants and microorganisms;

[0071] This combination 1 is mainly aimed at the removal of nutrients and is suitable for the treatment of agricultural drainage or mild industrial wastewater. It can significantly improve water quality while maintaining biodiversity.

[0072] Combination 2: Multi-level biological filtration module + microbial electrolysis cell

[0073] Primary treatment: removal of suspended and larger organic matter through multi-level biofiltration modules;

[0074] Electrochemical treatment: The water then flows into a microbial electrolysis cell, where electroactive microorganisms convert remaining organic matter into electricity, further purifying the water.

[0075] This combination 2 is suitable for the treatment of high-concentration organic wastewater, which not only improves the removal rate of organic matter but also recovers part of the energy.

[0076] Combination 3: Natural ecological purification park + physical adsorption and precipitation unit

[0077] Ecological treatment: The water first flows through a natural ecological purification park to remove most organic matter and nutrients;

[0078] Fine treatment: It then passes through physical adsorption and sedimentation units to remove tiny suspended particles and residual dissolved pollutants;

[0079] This combination 3 is suitable for deep treatment of urban sewage and can effectively improve water quality to meet higher discharge or reuse standards.

[0080] Combination 4: Multi-level biofiltration module + microbial electrolysis cell + physical adsorption and precipitation unit

[0081] Primary treatment: Water passes through a multi-level biological filtration module to remove large particles and some organic matter;

[0082] Electrochemical treatment: It then enters the microbial electrolysis cell to further degrade organic matter and generate electricity;

[0083] Final fine treatment: Finally, tiny suspended particles and residual dissolved pollutants are removed through physical adsorption and precipitation units;

[0084] This combination 4 is suitable for various types of wastewater treatment, especially where high-standard purification is required. It can remove various pollutants to the maximum extent and provide the cleanest effluent.

[0085] In one embodiment, it also includes an integrated control unit equipped with a sensor network for real-time monitoring of the working status of each module and water quality parameters to optimize the overall water treatment efficiency;

[0086] The integrated control unit collects the working status and water quality parameters of each module in real time through the connected sensor network. The collected data is transmitted to the integrated control unit for continuous monitoring and analysis. Based on the data analysis results, the control unit automatically adjusts the water flow, treatment time, and chemical dosage of each module to improve treatment efficiency and water quality.

[0087] In one embodiment, feedback control is also included, which collects real-time water quality data from multi-level biological filtration modules, natural ecological purification parks, microbial electrolysis cells, and physical adsorption and precipitation units to automatically adjust the water flow path and residence time to achieve optimal treatment effects on various pollutants.

[0088] In one embodiment, it also includes waste heat recovery, collecting and utilizing the heat generated in the microbial electrolysis cell and the chemical reaction to preheat the water entering the system, reducing the additional energy demand and improving the overall energy efficiency; installing a heat exchanger in the microbial electrolysis cell and the area involving the chemical reaction to capture the heat generated in the reaction process, and efficiently transferring the heat energy through the heat exchanger with minimal impact on the water treatment process. By setting pipes and pumps, the captured heat is transferred to the location where the water flow enters the treatment system, and a preheating water tank is installed at the location where the water flow enters the treatment system to store and preheat the water entering the system. By adjusting the temperature of the incoming water, a more suitable growth environment is provided for microorganisms, especially in areas with colder climates;

[0089] Specifically, when the microbial electrolysis cell and chemical reactions are taking place, the heat generated is captured by a heat exchanger and transferred to the preheating pool through thermal energy. The water entering the system first flows through the preheating pool, where the captured heat is used to raise the water temperature and reduce the energy consumption required to heat the water in other parts. The preheated water enters the water treatment system. The higher water temperature helps to increase the activity of microorganisms and the efficiency of chemical reactions, thereby enhancing the water treatment efficiency of the entire system.

[0090] The following steps are involved:

[0091] S1. Adjust the operating parameters of the multi-level biological filtration module, the natural ecological purification park, the microbial electrolysis cell, the physical adsorption and precipitation unit based on the real-time water quality monitoring data received by the integrated control unit;

[0092] S2. Perform water treatment on the adjusted water treatment system;

[0093] S3. Monitor the quality of treated water and further adjust water treatment parameters based on the monitoring results to optimize the treatment effect.

[0094] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
