印染工业废水处理模式的经济学分析

Economic analysis of printing and dyeing industrial wastewater treatment mode

在对印染工业废水处理模式调查分析的基础上,对绍兴市纺织印染工业废水处理模式进行了研究讨论。根据治理的主体差异性,将水污染处理模式分为企业自主处理模式、政府主导处理模式、企业预处理-政府集中处理模式三种类型,从激励机制、成本、监管机制和处理效率等四个方面对这三种治理模式进行经济学比较分析。针对企业预处理-政府集中处理模式存在的企业自建废水厂重复投资,占地面积大、废水处理交易成本较高、适用范围有限,局部区域环境压力增大等问题,提出允许印染企业共享污水预处理厂、推进第三方治理产业化、推进排污权交易市场化的对策建议。

Based on the investigation and analysis of the wastewater treatment modes of printing and dyeing industry,the wastewater treatment modes of textile dyeing and printing industry in Shaoxing were studied and discussed.According to the difference of governance subject,the water pollution treatment mode is divided into three types：enterprise self-processing mode,government-led processing mode,enterprise pretreatment-government centralized processing mode. Then,from the four aspects of incentive mechanism,cost,supervision mechanism and processing efficiency,comparative analysis economically were made on the modes. In response to the repeated investment in enterprises＇ self-constructed wastewater plants,large land area required,high transaction costs for wastewater treatment,limited scope of application,and increasing environmental pressure in local areas,we propose to allow the printing and dyeing enterprises to share the sewage pretreatment factories,promote the industrialization of the thirdparty governance and facilitate the countermeasures and suggestions on market-oriented emission trading.
