BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Figure 1 It is a schematic diagram of the system flow of the present invention;

[0046] Figure 2 It is a schematic diagram of the process of the present invention. DETAILED DESCRIPTION

[0047] 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.

[0048] In view of the current problems of complicated operation of the relevant systems for reducing sludge in septic tank feces and low sludge treatment efficiency, a treatment optimization system based on septic tank feces sludge reduction is proposed. Figure 1 The system includes a sludge concentration module, a biological treatment module, a physical and chemical treatment module, a sludge dewatering module, a control and monitoring module, and an optimization module, wherein:

[0049] The sludge concentration module concentrates the sludge in the septic tank feces, flows the concentrated sludge into the biological treatment module, and calculates the sludge concentration efficiency Wsxl. The calculation formula is as follows:

[0050]

[0051] The improvement of sludge concentration efficiency means that less organic matter, nitrogen, phosphorus and other substances extracted from sludge remain in the wastewater, which helps to reduce the organic matter content and nutrient concentration in the wastewater and reduce water pollution. In the formula, Wsxl represents the sludge concentration efficiency, Cswn represents the initial sludge solid content, and Nswn represents the sludge solid content after concentration. The above values ​​are obtained through system monitoring. By calculating the sludge concentration efficiency, the efficiency of extracting and concentrating organic matter, nitrogen, phosphorus and other nutrient elements from septic tank sludge can be determined, which is conducive to more effective recycling of these valuable resources for fertilizer production or other purposes, realizing resource reuse and saving natural resources.

[0052] The biological treatment module uses microorganisms to degrade organic matter in the sludge, brings the biologically treated sludge into the physical and chemical treatment module, and calculates the biological treatment sludge efficiency Scxl. The calculation formula is as follows:

[0053]

[0054] An efficient biological sludge treatment system can degrade organic matter more effectively, release more energy, improve the efficiency of energy recovery, reduce dependence on external energy, and reduce the operating cost of the treatment system. In the formula, Scxl represents the efficiency of biological sludge treatment, Csyj represents the initial organic matter concentration, and Clyj represents the organic matter concentration after treatment. The above values ​​are obtained through system monitoring. Calculating the efficiency of biological sludge treatment is not only helpful to improve the treatment capacity and treatment effect of the biological treatment system, but also helps to reduce the negative impact on the environment, protect water resources and ecological environment, and is conducive to sustainable development.

[0055] The physical and chemical treatment module further separates and treats the sludge in the septic tank through flocculation sedimentation and centrifugal separation operations, and calculates the physical and chemical treatment sludge efficiency Whxl. The calculation formula is as follows:

[0056]

[0057] The calculation of the efficiency of physical and chemical treatment of sludge can help optimize the treatment process, guide operators to reasonably adjust the treatment parameters, improve the efficiency and stability of the treatment system, and reduce the treatment cost. In the formula, Whxl represents the efficiency of physical and chemical treatment of sludge, Wcsj represents the sludge treatment time, Wcwd represents the sludge treatment temperature, Hxjl represents the added chemical dosage, Hhsd represents the physical and chemical mixing speed, Cswn represents the initial sludge solid content, Wnsd represents the sludge humidity, and Wntj represents the initial volume of the sludge. The above values ​​are automatically obtained by the system. Improving the efficiency of physical and chemical treatment of sludge means that more organic matter, heavy metals and other pollutants are effectively removed or concentrated, reducing the pollution of waste to the environment and reducing the organic load and pollutant concentration in wastewater.

[0058] The sludge dewatering module dehydrates the concentrated sludge, increases the solid content, reduces the volume, and calculates the sludge dewatering efficiency Wnts. The calculation formula is as follows:

[0059]

[0060] By improving the sludge dewatering efficiency, drier sludge solids can be obtained and the recycling rate of resources can be improved. For example, sludge can be further treated by incineration, composting, etc. to achieve energy recovery and resource utilization of resources. In the formula, Wnts represents the sludge dewatering efficiency, Tssj represents the sludge dewatering time, Tssw represents the temperature of the sludge sewage equipment, Tsjl represents the added dehydration dosage, Cswn represents the initial sludge solid content, Wnsd represents the humidity of the sludge, Shtj represents the sludge volume after dehydration, and Sjtj represents the sludge volume before dehydration. The calculation of sludge dewatering efficiency can help optimize the dehydration process, guide operators to reasonably adjust dehydration parameters, strengthen monitoring of equipment operation, improve dehydration effect, and reduce treatment costs;

[0061] The control and monitoring module is used to monitor the sludge content in the feces of the septic tank after the above treatment, and calculate the maximum sludge content value Zdhl. The calculation formula is as follows:

[0062]

[0063] Calculating the maximum sludge content can help determine the design parameters of the treatment system, such as the volume of the sludge tank, the specifications and capacity of the treatment equipment, etc., to ensure that the system can process and accommodate sludge with the maximum content. In the formula, Zdhl represents the maximum sludge content, Vsts represents the sludge volume, Wnsd represents the humidity of the sludge, and ε represents the loose proportion in the sludge. Indicates the incompressible proportion in sludge. Determining the maximum content of sludge helps optimize treatment efficiency and guide operators to reasonably arrange treatment cycles and operation methods to maximize the throughput of sludge treatment and improve treatment efficiency.

[0064] The control and monitoring module compares the calculated maximum sludge content value Zdhl with the internally set sludge content threshold value Hlyz in the feces of the septic tank to determine whether the sludge in the feces of the septic tank exceeds the standard. The judgment method is as follows:

[0065] When the maximum sludge content value Zdhl exceeds the sludge content threshold value Hlyz in the feces of the septic tank, it shows that the sludge content does not meet the reduction standard. The system will generate a sludge content adjustment optimization signal Tzyh and send it to the optimization module, triggering the system to automatically adjust the treatment process, improve the dehydration efficiency or take other measures to reduce the sludge content to an acceptable level. At the same time, the system will record the sludge content exceeding the standard and the adjustment measures taken for future analysis and optimization of the treatment process. Through this refined monitoring and control method, the deficiencies of the sludge treatment system can be discovered in time, and effective measures can be taken to adjust and optimize, so as to ensure the normal operation of the system, efficient treatment of sludge, and meet the environmental protection requirements of reduction and emission reduction;

[0066] The optimization module calculates the sludge treatment efficiency improvement rate Wctg, and the calculation formula is as follows:

[0067]

[0068] Improving the sludge treatment efficiency can shorten the treatment cycle and time, speed up the sludge treatment, reduce the waiting time during the treatment process, and improve production efficiency. In the formula, Wctg represents the sludge treatment efficiency improvement rate, Xcll represents the new sludge treatment efficiency, and Odxl represents the old sludge treatment efficiency. The above efficiency values ​​are obtained through system record logs. By calculating the sludge treatment efficiency improvement rate, the system's treatment efficiency of the sludge in the septic tank feces can be clearly reflected. When the sludge content adjustment optimization signal Tzyh is received and the sludge treatment efficiency improvement rate does not exceed 60%, it means that the sludge reduction in the septic tank feces is not up to standard. When the treatment efficiency cannot be improved, the system will automatically react and repeat the above-mentioned related operations to re-treat the sludge in the septic tank feces.

[0069] A treatment optimization method based on sludge reduction in feces in a septic tank specifically comprises the following steps:

[0070] S1, the sludge in the septic tank feces is concentrated through the sludge concentration module, the concentrated sludge flows into the biological treatment module, and the sludge concentration efficiency Wsxl is calculated;

[0071] S2, the biological treatment module uses microorganisms to degrade organic matter in the sludge, brings the biologically treated sludge into the physical and chemical treatment module, and calculates the biological treatment sludge efficiency Scxl;

[0072] S3, the physical and chemical treatment module further separates and treats the sludge in the septic tank feces through flocculation sedimentation and centrifugal separation operations, removes solids and organic matter, and discharges the treated sludge into the sludge dewatering module, and calculates the physical and chemical treatment sludge efficiency Whxl;

[0073] S4, sludge dewatering module dewaters the concentrated sludge, increases the solid content, reduces the volume, and calculates the sludge dewatering efficiency Wnts;

[0074] S5, the control and monitoring module is used to monitor the sludge content in the feces of the septic tank after the above treatment, and calculate the maximum sludge content value Zdhl. The control and monitoring module compares the calculated maximum sludge content value Zdhl with the sludge content threshold value Hlyz set in the septic tank feces, determines whether the sludge in the septic tank feces exceeds the standard, and generates a sludge content adjustment optimization signal Tzyh and sends it to the optimization module;

[0075] S6. The optimization module adjusts the optimization signal Tzyh according to the sludge content, and once again cycles through the operations of the above modules. It calculates the sludge treatment efficiency improvement rate Wctg and generates a system optimization parameter report that is sent to the central control screen.

[0076] Through the workflow and related methods of the above system, the sludge in the septic tank feces is reduced by using an automated workflow, which reduces the difficulty of system operation and improves the treatment efficiency of sludge reduction in the septic tank feces.

[0077] 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.
