[0014] The technical solutions in the embodiments of the present application will be described clearly and completely below with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0015] The above purposes, features and advantages of the present application will be more obvious and easy to understand. The present application will be further described in detail below with the drawings and specific embodiments.

[0016] In an exemplary embodiment, as shown in Figure 1 The present application provides a composite microbial efficient integrated sewage treatment device, which comprises a microbial filler bed, a water quality monitoring sensor module 1, an information control system 2, a microbial delivery module 3, an aeration module 4 and a comparator 6. The microbial filler bed is arranged in the water body. The signal output end of the water quality monitoring sensor module 1 is connected with the signal input end of the comparator 6, and the signal output end of the comparator 6 is connected with the signal input end of the information control system 2. The signal output end of the information control system 2 is connected with the control end of the microbial delivery module 3 and the control end of the aeration module 4 respectively.

[0017] The water quality monitoring sensor module 1 is used for detecting the water quality index of the water body in real time. The comparator 6 is used for comparing the water quality index with the index threshold value, and sending a high level to the information control system 2 when the water quality index is greater than the index threshold value. Exemplarily, the index threshold value is equal to the average water quality index value of the previous day or the set index limit value.

[0018] The information control system 2 is used for controlling the microbial delivery module 3 to deliver the composite microorganism to the water body when the high level is received, and the composite microorganism is attached to the microbial filler bed.

[0019] The microbial filler bed is used for providing a growth environment for the composite microorganism, and diffusing the attached composite microorganism to the water body through water flow flushing, and degrading the pollutants in the water body by using the metabolic activity of the composite microorganism.

[0020] The information control system 2 is also used to control the aeration module 4 to transfer oxygen in the air to the water body to supply the oxygen required for the metabolism of the aerobic microorganisms in the complex microorganisms.

[0021] The present application integrates aeration and microorganisms in one device, which is applied to the treatment of micro-polluted lakes, has simple construction, can quickly treat the polluted water body, and has certain application prospect in the treatment and repair of the polluted lakes.

[0022] As an optional implementation, the microbial filler bed comprises a main device 9, an electric device, a plurality of microbial beds 7 and a plurality of fixed supports 8. The main device 9 is hollow on four sides; the microbial bed 7 is a hollow plastic pipe, which is filled with porous materials, and the outer wall of the hollow plastic pipe is a hollow mesh. The plurality of microbial beds 7 are located in the main device 9 and are arranged in an array; each row of microbial beds arranged perpendicular to the water flow direction is connected and fixed by a fixed support 8. Both ends of each fixed support 8 are connected to the electric device; the electric device is used to drive the fixed support 8 to make each row of microbial beds perpendicular or parallel to the water flow direction. For example, when the complex microorganisms are generated initially, the electric device drives the fixed support 8 to make each row of microbial beds perpendicular to the water flow direction, and when the complex microorganisms reproduce for a preset time, the electric device drives the fixed support 8 to make each row of microbial beds parallel to the water flow direction.

[0023] The microbial filler bed can also be called a floating bed. The microbial filler bed mainly serves as a carrier for microbial biofilm formation and provides a growth environment for microorganisms. A single microbial bed 7 is a hollow plastic pipe with a diameter of 8-10 cm, which is filled with porous materials such as volcanic rock and ceramic particles for microbial growth. The outer wall is a hollow mesh, which facilitates the entry of water flow into the pipe. The microbial bed 7 is fixed in the main device 9 (such as the dashed rectangle in Figure 2 ), which is similar in shape to a container but is hollow on four sides. The microbial feeding pipe 10 is located at the bottom of the main device 9, directly below the microbial bed 7, and the microbial feeding pipe 10 can be linked or not linked to the microbial bed 7. The microorganisms are released into the main device through the pipe and diffuse through the water body, and finally adhere to the microbial bed 7.

[0024] As another optional implementation, in order to improve the degree of automation and the effect of complex microorganisms on degrading pollutants in the water body, the microbial filler bed can be further set as a self-adaptive microbial filler bed. The self-adaptive microbial filler bed can automatically adjust the impact angle of the biological bed and the water flow according to the water flow direction and the running time of the microbial bed 7. When the microorganisms are generated initially, the microbial bed 7 will be perpendicular to the water flow direction, please see Figure 2 the first three rows of microbial beds from left to right, which block the water flow impact through the outermost microbial bed 7, reduce the internal water flow speed, and protect the growth of microorganisms; when the microorganisms reproduce for a period of time, the microbial bed 7 will be parallel to the water flow direction, please see Figure 2The fourth row of the microbial bed from left to right is washed by the water flow to flush the dirt attached to the outer surface of the microorganism, and also helps the growing microorganism to diffuse the water body and purify the water body. Generally, the specific surface area of the microbial filler is large, the biofilm is evenly distributed on the filler, and there is no obvious mud accumulation and no agglomeration phenomenon; the porosity is large, the biofilm is not blocked, and the oil in the water is not easy to stick to affect the treatment effect; the compressive strength is high, and it has high salt resistance and corrosion resistance; the hydrophilic performance is good, and the microorganism is easy to attach; the chemical and biological stability is strong, and no harmful substances are dissolved to cause secondary pollution.

[0025] In an exemplary embodiment, in order to keep the posture of the microbial bed 7 stable, each row of microbial beds arranged perpendicular to the water flow direction is also fixed by ropes and air floating pads bound at the top, so that the microbial bed 7 does not move in the water and the posture does not roll over.

[0026] As another optional implementation, the microbial delivery module 3 includes a microbial agent storage tank, a liquid adding system, and a plurality of delivery pipelines 10. The plurality of delivery pipelines 10 are located inside the main body device 9; one delivery pipeline 10 is arranged below one row of microbial beds fixed by a fixed support 8. One end of the liquid adding system is connected to the microbial agent storage tank, and the other end of the liquid adding system is connected to the plurality of delivery pipelines 10 respectively. The liquid adding system is connected to the information control system 2; the liquid adding system is used to deliver the complex microorganism in the microbial agent storage tank to the water body through the plurality of delivery pipelines 10 under the control of the information control system 2, and the complex microorganism is attached to the plurality of microbial beds 7. The microbial delivery is agent delivery.

[0027] Unlike the telescopic microbial bed, in order not to affect the rotation of the microbial bed 7, the delivery pipeline 10 is located at the bottom instead of the middle of the microbial bed 7, and is attached to the microbial bed 7 through the water body.

[0028] Exemplarily, the liquid adding system includes an electronic valve and a delivery pipeline. One end of the delivery pipeline is connected to the microbial agent storage tank, and the other end of the delivery pipeline is connected to the plurality of delivery pipelines 10 respectively; the electronic valve is arranged on the delivery pipeline. The electronic valve is connected to the information control system 2, and the electronic valve is used to open or close under the control of the information control system 2 to control the delivery and stop of the agent.

[0029] The electronic valve can also be networked for online control.

[0030] As another optional implementation, in order to effectively control the total amount of complex microorganism delivery, in the case of fixed delivery power (i.e. fixed value of agent delivery amount per minute), the total amount of delivery can be controlled by the delivery time of the information control system 2, and the specific delivery time can be set on the system interface.

[0031] As an optional embodiment, the water quality monitoring sensor module 1 is a multifunctional integrated sensor for detecting multiple water quality indicators of the water body. The multiple water quality indicators include pH value, ORP value, temperature, conductivity, total dissolved solids, dissolved oxygen content, turbidity, salinity, suspended solids concentration, ammonia nitrogen concentration, total nitrogen concentration, chemical oxygen demand, total organic carbon, oil content in water, cyanobacterial number, and chlorophyll content.

[0032] The water quality monitoring sensor module 1 is used as a surface water multi-parameter water quality detection sensor, which can simultaneously detect 5-10 water quality indicators. The above water quality indicators can be reduced or increased according to actual conditions.

[0033] As an optional embodiment, the aeration module 4 is used to transfer oxygen in the air to the water body to be treated to supply the required amount of oxygen for aerobic metabolism, and to uniformly mix the water body to achieve the purpose of biological treatment.

[0034] As another optional embodiment, in order to improve the aeration effect and save the operation cost of the aeration module 4, a control parameter can be used for a contrast experiment under laboratory conditions. The best coupling point of aeration and microbial action is determined by considering multiple factors such as black and odorous water degradation efficiency, composite microbial agent dosage, hydraulic retention time, and comprehensive operation cost, to determine the key parameters such as aeration time, aeration amount, and bubble diameter.

[0035] The specific process of using the control variable method for a contrast experiment includes: setting different aeration times, different aeration amounts, and different bubble diameters; combining the aeration time, aeration amount, and bubble diameter to obtain multiple combination parameters; using the multiple combination parameters for a contrast experiment, and determining the combination parameter with the best water treatment effect as the best coupling parameter.

[0036] For example, during the trial operation of the equipment, by setting full aeration, aeration-stop aeration cycle for 12 hours, aeration-stop aeration cycle for 8 hours, bubble diameter of 0.8 mm, bubble diameter of 1.2 mm, bubble diameter of 2 mm, aeration amount of 1.5 m 3 / h, aeration amount of 3 m 3 / h, aeration amount of 6 m 3 / h, aeration amount of 10 m 3 / h, etc. (the above variables can be flexibly set according to the actual water body and equipment conditions), the three parameters are combined, for example: full aeration + bubble diameter of 0.8 mm + aeration amount of 1.5 m 3 / h, a total of 24 cases, and the best combination is set as the best coupling parameter (best coupling point) according to the water treatment effect before and after the experiment.

[0037] As an optional embodiment, the information control system 2 is used for monitoring and control of the whole system, including operation conditions of each sub-module, monitoring data collection, operation start control of each sub-module, etc. Meanwhile, system operation data can be uploaded to a cloud platform.

[0038] As an optional embodiment, the composite microorganism high-efficiency integrated sewage treatment device further comprises a power supply guarantee module 5.

[0039] As another optional embodiment, the power supply guarantee module 5 is used for power supply guarantee of the whole system, which is composed of a solar photovoltaic panel power supply system and municipal power supply (power grid). The power supply guarantee module 5 comprises a photovoltaic power generation module and a power grid, both of which are used for power supply of the information control system 2.

[0040] In an example, one power supply mode of the photovoltaic power generation module and the power grid can be that, in the case of strong sunlight, the energy stored by the solar energy is used preferentially, and when the energy stored by the solar energy is insufficient to meet the power demand of the equipment, the municipal power supply is used.

[0041] As an optional embodiment, with reference to Figure 1 , the composite microorganism high-efficiency integrated sewage treatment device further comprises a camera. The camera is used for monitoring the operation environment of the information control system 2, the microorganism feeding module 3 and the aeration module 4, obtaining monitoring video, and connecting the monitoring video to the information control system 2.

[0042] The composite microorganism high-efficiency integrated sewage treatment device further comprises an auxiliary module. The auxiliary module is used for system equipment operation assistance, including system information storage medium, emergency power supply equipment, etc. Data protection in the auxiliary module refers to that, through a hard disk, cloud space or the like, monitoring data and equipment operation state data are backed up in time. Safety protection refers to that, through increasing equipment shell, fixation and lightning protection measures, safety protection is performed on the equipment.

[0043] In the device, the water quality monitoring and sensing module 1 mainly monitors water quality of the water body. When the water quality does not meet the system set requirement, the information control system 2 controls the microorganism feeding device to feed water treatment composite microorganisms in the water body, the aeration module 4 improves microorganism activity through aeration, the microorganisms reproduce in large quantities in the microorganism filler bed, and metabolic activity degrades pollutants, so that water body purification effect is achieved.

[0044] The system of the present application is applied to a water temperature of 15-30℃ and a water area of 600m 2In the water body (water depth 1.2 m), under the condition that the water body has no water exchange with the outside world, the poor V-class water body can achieve the following effects after being treated for 10 days: 1) TP (total phosphorus) removal rate: 60%; 2) COD (chemical oxygen demand) removal rate: 50%; 3) TN (total nitrogen) removal rate: 70%.

[0045] The technical features of the above embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

In conclusion, the content of the present disclosure should not be understood as a limitation of the present application.
