绍兴印染企业中水回用系统半年度电耗分析数据

中水回用系统吨水耗电量对印染用电企业是一个非常重要的指标。本数据知识产权旨在通过分析绍兴滨海工业园内部分印染企业从1月到6月的中水回用系统电耗数据，提供一种科学的评估方法，以量化系统运行的能效表现。通过将每日吨水电耗分为I、II、III三个等级，并计算各等级占比，再运用加权评分系统综合评估半年度运行情况，最终给出“良好”“中等”“差”三个评价结果，为企业提供改进措施建议。此数据知识产权的应用不仅帮助企业实时掌握中水回用系统的运行状况，还提供了有针对性地改进措施，有助于企业节能减排，提升整体运营效益。同时，通过分析各评级所占比例，可进一步指导前端工艺及设备的运行参数调整，优化运行方案，及时发现并解决系统运行中的问题，对中水回用系统膜产品更新和膜系统设计提供有价值的参考。若结果为“良好”，说明系统运行高效、能耗低，无需对工艺参数优化，建议定期维护设备，保持现有操作参数，持续监测电耗变化；若结果为“中等”，系统运行效率一般，需关注能耗较高的工艺环节，考虑调整中水系统流量、压力参数，增加预处理步骤，以减缓膜污染，提高系统效率；若结果为“差”，系统运行效率低，能耗高，立即进行系统检查，优化工艺。1.数据收集：收集半年内滨海工业园印染企业中水回用系统的日用水量、电耗量等。2数据计算：日吨水电耗=当日用电量/（总水量-外排水量），计算出日吨水电耗W（kW·h/m3）。3.数据分析：对日吨水电耗进行等级评价，当日吨水电耗≤1.75，评价为A级；当1.75＜日吨水电耗≤2.6，评价为B级；当日吨水电耗＞2.6，评价为C级。汇总半年度各评价的总数Sa、Sb、Sc，评价A级占比Pa=Sa/（Sa+Sb+Sc）*100%，评价B级占比Pa=Sb/（Sa+Sb+Sc）*100%，评价C级占比Pc=Sc/（Sa+Sb+Sc）*100%。为A、B、C级分别赋予不同的权重（A级=60，B级=30，C级=10），计算半年度的加权评分，最终评分=60*Pa+30*Pb+10*Pc。4.结果评定：根据得到的最终评分将企业半年度运行情况分为“良好”“中等”“差”，评分≥45为“良好”、45＞评分≥30为“中等”、30＞评分≥10“差”，并据评分提出运行改进建议。若结果为“中等”，系统运行效率一般，需关注能耗较高的工艺环节，考虑调整中水系统流量、压力参数，增加预处理步骤，以减缓膜污染，提高系统效率。

The electricity consumption per ton of water of the reclaimed water reuse system is a critical indicator for printing and dyeing enterprises. This dataset (with its associated intellectual property rights) aims to provide a scientific assessment method for quantifying the energy efficiency performance of reclaimed water reuse systems, by analyzing the electricity consumption data of such systems from some printing and dyeing enterprises in Shaoxing Binhai Industrial Park between January and June. By categorizing the daily electricity consumption per ton of water into three levels (A, B, C), calculating the proportion of each level, and applying a weighted scoring system to comprehensively evaluate the semi-annual operation status, this work finally provides three evaluation results: "Good", "Medium", and "Poor", along with targeted improvement suggestions for enterprises. The application of this dataset not only helps enterprises grasp the real-time operation status of their reclaimed water reuse systems, but also provides targeted improvement measures, which contributes to enterprises' energy conservation and emission reduction and overall operational efficiency improvement. Meanwhile, by analyzing the proportion of each rating, it can further guide the adjustment of operating parameters of front-end processes and equipment, optimize operation plans, timely detect and solve problems in system operation, and provide valuable references for membrane product renewal and membrane system design of reclaimed water reuse systems.

If the result is "Good", it means the system operates efficiently with low energy consumption, and there is no need to optimize process parameters. It is recommended to perform regular equipment maintenance, maintain existing operating parameters, and continuously monitor changes in electricity consumption. If the result is "Medium", the system operates with average efficiency. It is necessary to focus on process links with high energy consumption, consider adjusting the flow and pressure parameters of the reclaimed water system, and add pretreatment steps to slow down membrane fouling and improve system efficiency. If the result is "Poor", the system operates with low efficiency and high energy consumption, and immediate system inspection and process optimization are required.

1. Data Collection: Collect daily water consumption, electricity consumption and other relevant data of the reclaimed water reuse systems of printing and dyeing enterprises in the industrial park within half a year.
2. Data Calculation: Daily electricity consumption per ton of water = daily electricity consumption / (total water volume - external drainage volume), and the daily electricity consumption per ton of water W (kW·h/m³) is calculated.
3. Data Analysis: Conduct rating evaluation on the daily electricity consumption per ton of water:
- When daily electricity consumption per ton of water ≤ 1.75, it is rated as Level A;
- When 1.75 < daily electricity consumption per ton of water ≤ 2.6, it is rated as Level B;
- When daily electricity consumption per ton of water > 2.6, it is rated as Level C.
Summarize the total number of each rating in the half-year period: Sa, Sb, Sc. Calculate the proportion of each rating:
Proportion of Level A Pa = Sa / (Sa + Sb + Sc) * 100%;
Proportion of Level B Pb = Sb / (Sa + Sb + Sc) * 100%;
Proportion of Level C Pc = Sc / (Sa + Sb + Sc) * 100%.
Assign different weights to Levels A, B, and C respectively (Level A = 60, Level B = 30, Level C = 10), and calculate the semi-annual weighted score. The final score = 60*Pa + 30*Pb + 10*Pc.
4. Result Evaluation: Classify the semi-annual operation status of enterprises into "Good", "Medium", and "Poor" based on the final score:
- "Good" when final score ≥ 45;
- "Medium" when 45 > final score ≥ 30;
- "Poor" when 30 > final score ≥ 10.
Put forward operation improvement suggestions based on the score. If the result is "Medium", the system operates with average efficiency. It is necessary to focus on process links with high energy consumption, consider adjusting the flow and pressure parameters of the reclaimed water system, and add pretreatment steps to slow down membrane fouling and improve system efficiency.
