【摘要】：污水处理系统在处理污水达标排放的同时消耗大量能源与资源,为科学评估污水处理系统综合利用效率及对自然-经济系统可持续发展的影响,本文以齐齐哈尔污水处理厂为例,应用能值分析原理和方法,通过选取不同的因子,对模型A(污水处理系统+锅炉取暖系统)、模型B(污水处理系统+锅炉取暖系统+分布式光伏电站系统)、模型C(污水处理系统+水源热泵取暖系统)和模型D(污水处理厂+水源热泵取暖系统+分布式光伏电站系统),进行能值对比,包括四个模型的能值流和三个能值评价指标(能值产出率、环境负载率、能值可持续发展指标),最终建立模型,并在滨海地区进行推广。论文取得如下成果和认识:(1)经过数据比对分析,污水厂在增加水源热泵取暖系统与分布式光伏电站设备后,综合应用系统能值和效率均优于单一的运行系统。因此积极探讨不同产业间的融合,不仅会产生经济收益,还能优化产业结构,提高生态效益。四个模型环境负载率均低于1,对环境压力较小,可持续发展指数均在1到10之间,从生态学角度可以得到推广。(2)从能值流角度分析,单纯考虑不可更新资源,C、D模型表现最优。单纯考虑资金投入C模型表现最优,单纯考虑产出,B、D模型表现最优。A、B模型对不可更新资源依赖程度更高,资源短缺地区适合使用C、D模型。B、D模型更加适合能源短缺,经济发达地区。A、C模型适合资源充足,经济欠发达地区。(3)从能值产出率高出模式、环境负载率、可持续发展指数三个角度对比,D模型最优,其次是模型C,能值产出率基本与模型A持平,环境负载率、可持续发展指数均高于模型A,模型A效率较高,但是对环境压力最大,模型B环境压力角度考虑优于模式A,但是产出率下降,综合可持续发展指数与模型A相比下降,从经济角度和生态角度综合考虑也不推荐选择。
[Abstract]:The sewage treatment system consumes a lot of energy and resources while meeting the discharge standards, in order to scientifically evaluate the comprehensive utilization efficiency of the sewage treatment system and its impact on the sustainable development of the natural-economic system. Taking Qiqihar sewage treatment Plant as an example, this paper applies the principle and method of emergy analysis, and selects different factors to model A (boiler heating system of sewage treatment system). Model B (sewage treatment system Boiler heating system distributed Photovoltaic Power Station system), Model C (water source heat pump heating system of sewage treatment system) and model D (distributed photovoltaic power station system of water source heat pump heating system of sewage treatment plant), and the emergy values are compared. It includes the emergy flow of four models and three emergy evaluation indexes (emergy output rate, environmental load rate, emergy sustainable development index). Finally, the model is established and popularized in coastal areas. The achievements and understandings of this paper are as follows: (1) after data comparison and analysis, after adding water source heat pump heating system and distributed photovoltaic power station equipment, the energy value and efficiency of the integrated application system are better than that of a single operation system. Therefore, actively discussing the integration of different industries will not only produce economic benefits, but also optimize the industrial structure and improve ecological benefits. The environmental load rate of the four models is less than 1, the environmental pressure is small, and the sustainable development index is between 1 and 10, which can be extended from the ecological point of view. (2) from the point of view of emergy flow, only consider the non-renewable resources, C. The D model has the best performance. Considering the optimal performance of capital input C model and output alone, B, D model is the best. A, B model is more dependent on non-renewable resources, and C model is suitable for resource shortage areas. The D model is more suitable for energy shortage and economically developed areas. A, C model is suitable for the areas with sufficient resources and underdeveloped economies. (3) the emergy output rate is higher than that of the model, the environmental load rate and the sustainable development index are compared. D model is the best, followed by model C, the emergy output rate is basically the same as model A, the environmental load rate and sustainable development index are higher than model A, model A is more efficient, but the environmental pressure is the largest. The environmental pressure of model B is better than that of model A, but the output rate is decreased, and the comprehensive sustainable development index is lower than that of model A. from the economic and ecological point of view, the choice is not recommended.
