Description

Technical Field

[0001] The invention relates to the technical field of sewage treatment, and in particular to a pig slaughtering sewage purification monitoring method. Background Art

[0002] In the pig slaughtering industry, sewage treatment is a vital link, which is directly related to environmental protection and public health safety. With the continuous increase in slaughter volume, the amount of sewage generated has also increased significantly. It contains a large amount of organic matter, suspended matter, oil, microorganisms and other pollutants. If it is directly discharged without effective treatment, it will cause serious pollution and ecological damage to the water environment.

[0003] Existing monitoring methods for pig slaughter wastewater purification often monitor the effect of slaughter wastewater purification by analyzing data from a single sampling point and time point. Due to the uneven spatial distribution of pollutants in water bodies and their temporal variation characteristics, data from a single sampling point and time point are difficult to fully reflect the overall effect of slaughter wastewater purification. At the same time, the energy consumption of equipment and the use of chemicals in the slaughter wastewater purification process need to be used to consider the economy and sustainability of slaughter wastewater purification. However, the existing monitoring methods lack consideration of this, resulting in inaccurate monitoring results. Summary of the invention

[0094] S4. Collect the actual sewage treatment volume, sewage treatment equipment specifications and energy consumption, and sewage treatment agent usage;

[0095] The actual sewage treatment volume is used to determine the actual amount of sewage treated in a specific period of time. It is a direct indicator of sewage treatment efficiency and capacity.

[0127] S7. Perform weighted calculation on the water quality improvement evaluation results and the slaughterhouse wastewater treatment energy efficiency evaluation results to obtain a slaughterhouse wastewater purification evaluation index;

[0128] The purpose of step S7 is to comprehensively evaluate the water quality improvement effect and energy efficiency performance of the sewage treatment, so as to obtain a comprehensive evaluation index that fully reflects the performance of the sewage treatment system;

[0129] First, it is necessary to set weights for the water quality improvement evaluation results and the slaughterhouse wastewater treatment energy efficiency evaluation results respectively;

[0130] The water quality improvement evaluation weight reflects the importance of water quality improvement to environmental protection and public health safety; usually, water quality improvement is the primary goal of sewage treatment, so its weight is relatively high;

[0131] The energy efficiency evaluation weight reflects the economy and sustainability of the sewage treatment process; although energy efficiency is not the only criterion, in long-term operation, the level of energy efficiency directly affects the operating costs and environmental impact of the enterprise;

[0132] The calculation formula for the slaughterhouse wastewater purification evaluation index is:

[0133] CPI=w1×QI+w2×EI

[0134] Among them, CPI represents the slaughterhouse wastewater purification evaluation index, QI represents the water quality improvement evaluation result, EI represents the slaughterhouse wastewater treatment energy efficiency evaluation result, w1 and w2 are the weight coefficients of the water quality improvement evaluation result and the energy efficiency evaluation result respectively;

[0135] The factors affecting the setting of the weight coefficients of the water quality improvement evaluation results and the energy efficiency evaluation results include:

[0136] Environmental protection policies and regulations: The state or local government has clear regulations on the water quality standards for sewage discharge, which reflect the importance of water protection. If the water quality standards are very strict, the weight of the water quality improvement evaluation results should be increased accordingly. The government will introduce relevant policies to encourage energy conservation and emission reduction, and the weight of energy efficiency evaluation results will increase at this time to reflect the importance of environmental protection and sustainable development.

[0137] Operational objectives of the sewage treatment plant: If the main objective of the sewage treatment plant is to ensure that the effluent water quality meets high standards, the weight of the water quality improvement evaluation results should be dominant; when setting the weight, the long-term economic and sustainability of the sewage treatment plant should also be considered; efficient sewage treatment processes can not only reduce operating costs, but also reduce negative impacts on the environment;

[0138] Pollutant characteristics and treatment processes: Different types of pollutants have different degrees of harm to the environment and human health, so the weight of the water quality improvement evaluation results needs to be adjusted according to the actual situation; different treatment processes have different effects on energy efficiency; advanced treatment processes have higher energy efficiency, but the initial investment is larger; while traditional processes have lower energy efficiency, but lower operating costs; these factors need to be considered when setting weights;

[0139] Reliability and representativeness of monitoring data: The accuracy and reliability of water quality and energy efficiency monitoring data directly affect the accuracy of the evaluation results; the higher the monitoring frequency and the wider the coverage, the higher the representativeness and reliability of the data; it can be used as a reference factor when setting weights.

[0140] In this step, by weighting the water quality improvement evaluation results and the slaughterhouse wastewater treatment energy efficiency evaluation results, a comprehensive evaluation index that fully reflects the performance of the sewage treatment system can be provided; this comprehensive evaluation not only takes into account the core goal of water quality improvement, but also takes into account the economy and sustainability of the treatment process, making the evaluation results more comprehensive and objective; the setting of the weight coefficient takes into account a variety of influencing factors, including environmental protection policies and regulations, the operating objectives of the sewage treatment plant, the characteristics of pollutants and the treatment process, as well as the reliability and representativeness of the monitoring data; this flexibility allows the weight setting to be adjusted according to the specific conditions of different regions and different sewage treatment plants, thereby ensuring the pertinence and accuracy of the evaluation results; the comprehensive evaluation index provides a scientific basis for managers and decision makers; by comparing the comprehensive evaluation index with the predicted The purification evaluation threshold set can clearly determine whether the slaughterhouse wastewater purification is qualified, and then take corresponding measures to improve or optimize it; this data-based decision support helps to improve the efficiency and effectiveness of sewage treatment, promote environmental protection and public health safety; through comprehensive evaluation, it can timely discover problems and deficiencies in the sewage treatment process, and provide direction for continuous improvement; the continuous improvement mechanism helps to promote the continuous progress and improvement of slaughterhouse wastewater purification technology; the implementation process of step S7 emphasizes the importance of water quality improvement and energy efficiency improvement, which helps to enhance the environmental awareness of enterprises and the public; through open and transparent evaluation process and results, it can encourage enterprises to pay more attention to sewage treatment and take active measures to reduce pollutant emissions; at the same time, it can also guide the public to pay attention to environmental protection issues and jointly promote the construction of ecological civilization.

[0141] S8. Compare the slaughter wastewater purification evaluation index with the preset purification evaluation threshold. If the slaughter wastewater purification evaluation index exceeds the preset purification evaluation threshold, the pig slaughter wastewater purification is qualified. If the slaughter wastewater purification evaluation index does not exceed the preset purification evaluation threshold, the pig slaughter wastewater purification is unqualified.

[0142] The slaughter wastewater purification evaluation index is used as the comparison data input;

[0143] Automatically comparing the slaughterhouse wastewater purification evaluation index with a preset purification evaluation threshold through a preset algorithm or software program;

[0144] According to the comparison results, it is judged whether the slaughter wastewater purification is qualified; if the evaluation index exceeds the preset threshold, it is considered that the purification is qualified; if it is lower than the preset threshold, it is judged that the purification is unqualified;

[0145] Feedback the comparison results to the operation and management personnel of the sewage treatment plant in a timely manner so that they can understand the purification effect in time and take corresponding measures;

[0146] For unqualified purification, the reasons should be analyzed in depth and improvement measures should be proposed based on the specific reasons;

[0147] According to the analysis results, adjust the sewage treatment process parameters, repair or replace equipment, optimize the use of chemicals, etc. to improve the sewage purification effect and ensure that the discharge meets the standards;

[0148] In order to ensure the continuous stability of sewage treatment effects, the slaughterhouse sewage purification effect should be re-inspected regularly, the purification evaluation index should be recalculated and compared with the preset threshold;

[0149] With the update of environmental protection policies, the advancement of treatment technology and the changes in actual operation conditions, the preset purification evaluation thresholds should be adjusted in a timely manner to adapt to new requirements;

[0150] The factors affecting the setting of the preset purification evaluation threshold include:

[0151] Environmental standards: The primary consideration is the national and local environmental standards for sewage discharge, which usually stipulate the maximum allowable concentration limits of various pollutants in sewage; the preset purification evaluation threshold should be strictly lower than or equal to these standard limits to ensure that the discharged sewage will not pollute the water environment;

[0152] Industry best practices: Refer to the best practices of other advanced slaughtering companies in the industry in wastewater purification to understand their purification effects and evaluation criteria; this helps to set a target threshold that is both challenging and achievable;

[0153] Technical feasibility: Consider the current sewage treatment technology and equipment processing capacity, as well as the possible future technology upgrade space; the preset threshold should be based on the best purification effect that can be achieved under current technical conditions, while also leaving some room for technological progress;

[0154] Economic cost: Equipment energy consumption and chemical usage in the sewage treatment process will increase operating costs. The setting of preset thresholds requires a balance between purification effect and operating costs to ensure that economic costs are minimized while meeting environmental protection requirements.

[0155] Sustainability: Consider the long-term operational stability and sustainability of the sewage treatment system; the preset threshold should be conducive to promoting the continuous improvement and innovation of sewage treatment technology, promoting the recycling of resources and energy conservation and emission reduction;

[0156] Risk assessment: Assess possible environmental risks, such as water pollution, ecological damage, etc.; preset thresholds should be able to effectively reduce the probability and impact of these risks.

[0157] In this step, by comparing the slaughterhouse wastewater purification evaluation index with the preset purification evaluation threshold, it can ensure that the sewage treatment effect meets the national and local environmental protection standards, effectively prevent the direct discharge of sewage that has not been fully treated, and thus protect the water environment and ecological safety; the use of three-dimensional mapping data information and multi-time point sampling overcomes the limitations of traditional single sampling point monitoring, comprehensively reflects the spatial and temporal variation characteristics of slaughterhouse wastewater, and improves the accuracy and reliability of monitoring results; when setting the preset purification evaluation threshold, comprehensive consideration is given to factors such as technical feasibility, economic cost and sustainability, ensuring that while meeting environmental protection requirements, the economy of sewage treatment and the stability of long-term operation are also considered, which is conducive to the sustainable development of the enterprise; the comparison results are promptly fed back to the operation and management personnel of the sewage treatment plant so that they can promptly Understand the purification effect, conduct in-depth analysis of the reasons for unqualified situations, and propose and implement improvement measures; this rapid feedback mechanism helps to respond to problems quickly and improve sewage treatment efficiency; by regularly re-inspecting the slaughterhouse sewage purification effect and adjusting the preset purification evaluation threshold in time according to changes in environmental protection policies, technological progress and actual conditions, the timeliness and adaptability of the monitoring method are ensured, and the continuous improvement and innovation of sewage treatment technology are promoted; through risk assessment, the setting of the preset purification evaluation threshold also takes into account possible environmental risks, which helps to reduce the probability and impact of these risks and enhance the ability to prevent and control environmental risks; this step ensures the compliance, accuracy, economy and sustainability of pig slaughterhouse sewage purification through scientific and comprehensive monitoring and evaluation methods, providing strong guarantees for environmental protection and public health safety.
