【摘要】：再生水作为城市的第二水源,能有效缓解水资源短缺危机。价格是再生水市场的核心要素,再生水回用工程的经济性在很大程度上受再生水价格的影响。我国大部分地区,尤其是西部干旱地区,自来水价格及水资源费较低,而再生水的制水成本相对偏高,制定合理的再生水价格是比较困难的。本文通过分析国内外研究现状,并结合我国的实际情况,提出再生水的价格制定,应在合理划分再生水服务市场的前提下,充分发挥阶梯水价的调节作用,通过水价引导用户选择使用再生水。文中通过分析分散式和集中式再生水对市场主体的影响,采用费用效益函数建立集中式和分散式的临界距离模型,进而对集中式再生水回用的服务范围及分散式再生水回用工程的最小经济规模进行研究。采用平均成本价值模型计算再生水的平均制水成本,分析不同回用对象和不同服务市场的定价方案。并基于再生水的制水成本和再生水厂的利润函数,运用边际成本、价格弹性等建立再生水的阶梯递减定价模型,通过模型对再生水的水量、水价划分三个阶梯。最后,结合西安市的实际情况,运用本文建立的模型,对西安市集中式和分散式再生水的服务市场范围进行划分,并确定分散式再生水回用的最小经济规模。同时,基于本文建立的再生水阶梯定价模型,采用MATLAB软件测算再生水的阶梯水量和水价,并比较分析测算结果与实际情况,验证了此定价模型的可操作性,为再生水价格的市场化发展,提供了理论依据。
[Abstract]:Reclaimed water, as the second source of water in the city, can effectively alleviate the crisis of water shortage, and price is the core element of the renewable water market. The economy of the reclaimed water reuse project is largely affected by the reclaimed water price. In most areas of China, especially in the arid areas of the west, the price of tap water and the cost of water resources are relatively low. However, the cost of reclaimed water is relatively high, so it is difficult to set a reasonable price of reclaimed water. This paper puts forward the pricing of reclaimed water by analyzing the domestic and foreign research situation and combining with the actual situation of our country. We should give full play to the regulating function of step water price on the premise of dividing the market of reclaimed water service reasonably. Through the analysis of the influence of decentralized and centralized reclaimed water on the main body of the market, the cost benefit function is used to establish the critical distance model of centralized and decentralized reclaimed water. Then the service scope of centralized reclaimed water reuse and the minimum economic scale of decentralized reclaimed water reuse project were studied. The average cost value model was used to calculate the average water production cost of reclaimed water. The pricing schemes of different reuse objects and different service markets are analyzed. Based on the water production cost of reclaimed water and the profit function of the reclaimed water plant, the stepwise decline pricing model of reclaimed water is established by using marginal cost and price elasticity. Through the model of water volume, water price divided into three steps. Finally, combined with the actual situation of Xi'an, the use of the model established in this paper. The service market scope of centralized and decentralized reclaimed water in Xi'an is divided, and the minimum economic scale of reclaimed water reuse is determined. At the same time, the ladder pricing model of recycled water based on this paper is established. The stepwise water quantity and water price of reclaimed water were calculated by MATLAB software, and the calculation results were compared with the actual situation. The feasibility of the pricing model was verified, which was the market-oriented development of the reclaimed water price. The theoretical basis is provided.
