Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a water pollution treatment method using an energy transfer method. Background Art

[0002] At present, apart from drought and water shortage, the biggest threat to China's water environment is water pollution.

[0003] Chinese patent application number: CN031339077, specifically discloses a combined process for sewage ecological treatment, which uses floating bio-bed technology as a pretreatment process and a subsurface artificial wetland system to organically combine the floating bio-bed technology with the artificial wetland sewage ecological treatment technology. The specific process is: the sewage passes through the regulating tank and is lifted by a water pump to the floating bio-bed system for pretreatment, the effluent from the floating bio-bed is precipitated in the sedimentation tank and then enters the subsurface wetland system, and the sludge is concentrated and then transported.

[0004] The above-mentioned sewage treatment method has certain shortcomings during its implementation: first, it does not give full play to the role of various organisms in the water ecosystem, but only utilizes the absorption of dissolved pollutants in the polluted water by plants. For insoluble organic particles, additional facilities can only be added to adopt gravity (or centrifugal) separation, filtration and physical adjustment measures to remove them; in addition, it fails to build the entire ecosystem of polluted water, and ignores the comprehensive treatment role of organisms other than aquatic plants as energy transfer carriers, which affects the treatment effect. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a water pollution control method using an energy transfer method, which converts most of the soluble and insoluble pollutants in the water body into high-order biological energy through energy transfer, separates them from the water body, and achieves the purpose of improving water quality.

[0006] To achieve the above object, the present invention adopts the following technical solution: a water pollution control method using energy transfer, comprising the following steps: (1) Cultivating oysters, stocking mullets, sea cucumbers and other filter-feeding and lick-feeding marine organisms in ponds; (2) Utilize naturally occurring marine plants such as kelp, agar, and Ulva pertusa in the pond, and add a small amount of beneficial microbial groups such as Nitrobacter and Bacillus; (3) Add some unicellular algae to decompose and absorb soluble pollutants such as nitrogen and phosphorus dissolved in the water.

[0007] Preferably, marine organisms are utilized to fully filter out solid nutrient particles such as leftover bait and feces in the edible tail water.

[0008] Preferably, marine animals, marine plants, phytoplankton and marine microorganisms are used to form a complete ecosystem of coexistence.

[0009] Preferably, pollutants such as nitrogen and phosphorus in the water body are absorbed and utilized by microbial flora, unicellular algae, and large aquatic plants through mineralization, nitrification, and biological fixation, transferring low-level energy to higher-level biological energy.

[0010] Preferably, aquatic animals in the water body are utilized to filter and consume organic particles suspended in the water body, and the chemical energy in the organic particles is transferred to the aquatic animals and converted into biological energy of their bodies.

[0011] The beneficial effects of the present invention are: 1. This energy transfer method for water pollution control only carries out water pollution control in the water body, does not build auxiliary facilities, does not occupy other land and space, does not increase investment in other facilities, and has low investment; 2. The water pollution control method of this energy transfer mode selects suitable organisms, builds a full ecosystem in the polluted water body, opens up the energy transfer channel, uses biological carriers to transfer pollutant energy and converts it into bioenergy, and establishes a stable water ecosystem; 3. This energy transfer method of water pollution control utilizes suitable aquatic animals to consume organic pollutant particles and their chemicals, and transfer and convert chemical energy into higher-order bioenergy; 4. This energy transfer method for water pollution control utilizes microbial flora and aquatic plants to transfer the chemical energy of soluble pollutants in the water and convert it into high-level bioenergy.

[0012] 5. This energy transfer method for water pollution control is based on the principle of energy transfer. It constructs a multi-trophic level and full-ecosystem aquaculture effluent purification system, opens up energy transfer channels, and utilizes aquatic organisms in different nutritional niches to comprehensively treat insoluble particulate nutrients and soluble inorganic nitrogen and phosphorus pollutants in polluted water bodies in a three-dimensional manner.

[0013] 6. This water pollution control method using the energy transfer method utilizes all levels of organisms in the entire ecosystem of the water body as energy carriers, which absorb nutrients, convert energy, and actively transfer energy to the highest level to become bioenergy of aquatic organisms, separate the energy from the water body, improve the water quality, and control the pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 It is a schematic diagram of the process flow of the present invention. DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0016] See also Figure 1 , a water pollution control method using energy transfer, comprising the following steps: (1) In ponds, oysters, mullets, sea cucumbers and other filter-feeding and lick-feeding marine organisms are raised, and the marine organisms are used to fully filter out the solid nutrient particles such as leftover bait and feces in the tail water; insoluble organic particles are the root cause of water pollution, and as they decompose, they continuously release various soluble pollutants into the water. Different aquatic animals in the water body are used to filter and eat the organic particles suspended in the water body, and transfer the chemical energy in the organic particles to the aquatic animals and convert them into biological energy for their bodies.

[0017] (2) Utilize naturally occurring marine plants such as kelp, agar, and Ulva pertusa in the pond, and add a small amount of beneficial microbial groups such as Nitrobacter and Bacillus; (3) Release some unicellular algae to decompose and absorb soluble pollutants such as nitrogen and phosphorus dissolved in the water. Use marine animals, marine plants, phytoplankton, and marine microorganisms to form a complete ecosystem of coexistence.

[0018] Pollutants such as nitrogen and phosphorus in water bodies are absorbed and utilized by microbial flora, unicellular algae, and large aquatic plants through mineralization, nitrification, and biological fixation, transferring low-level energy to higher-level biological energy.

[0019] Nitrogen in water bodies generally exists in the form of organic nitrogen, ammonium nitrogen, nitrate nitrogen, nitrite nitrogen, etc.; phosphorus exists in the form of phosphate, polyphosphate and organic phosphorus. After being absorbed by microorganisms, bacteria, algae and aquatic plants, nitrate nitrogen is reduced to nitrite nitrogen by nitrate reductase, and nitrite nitrogen is reduced to ammonium by nitrite reductase. Ammonium is fixed biologically to form protein energy in the body, which is upgraded from chemical energy to biological energy. Microorganisms, bacteria, algae and aquatic plants use the energy released by the oxidative decomposition of BOD5 in the water body or the poly-β-hydroxybutyric acid stored in the body to absorb phosphorus in the water body. Part of the phosphorus is used to synthesize ATP, and most of the phosphorus is collectively referred to as polyphosphate and stored in the cell body.

[0020] On the one hand, small aquatic plants and animals such as unicellular algae and copepods can accept energy transfer and absorb and utilize soluble pollutants in the water. On the other hand, their energy can also be transferred to higher levels through the food chain and become food for large aquatic animals, and their energy is converted into the highest level of large aquatic animal bioenergy.

[0021] Beneficial microbial flora in this ecosystem not only plays an energy transfer function, but also inhibits the reproduction of decomposing bacteria, inhibits the decomposition of organic matter particles, and blocks the further deterioration of water pollution.

[0022] After a period of purification, the water in the pond is refreshing and smooth, the water is clear and transparent, and the transparency reaches more than 4 meters. The visible organisms in the purification pond include fish such as sea bass, mullet, swimming fish, conger eel, kelp, wakame, Ulva perforata, shrimp, barnacles, clams, mud snails, moss, etc. The pond ecosystem is healthy and stable. From 2020 to 2022, the water quality of the purification pond was tested many times, and comparative tests of inlet and outlet water were also carried out. The results of several tests were better than the Class I discharge standards of the "Discharge Requirements for Marine Aquaculture Water" (SC / T9103) and the "Fishery Water Quality Standard" (GB11607).

[0023] The first step of this water pollution control method is to build a complete ecosystem of the water body, select suitable beneficial bacteria and other microorganisms, unicellular algae, aquatic plants, aquatic animals, etc. in appropriate quantity ratios, transplant them into the water body, and appropriately adjust their ratios or types to achieve a complete and stable water ecosystem. Based on the principle of energy transfer, a multi-trophic level full-ecosystem aquaculture tailwater purification system is constructed to open up energy transfer channels, and use aquatic organisms in different nutritional niches to three-dimensionally and comprehensively treat insoluble particulate nutrients and soluble inorganic nitrogen and phosphorus pollutants in polluted water bodies. All levels of organisms in the whole ecosystem in the water body act as energy carriers, absorb nutrients, convert energy, and actively transfer energy to the highest level, becoming bioenergy of aquatic organisms, separating from the water body, improving water quality, and controlling pollution.

[0024] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
