| 污水处理工艺选择准则 Selection criteria for wastewater treatment process 1) 城市污水处理工艺应根据处理规模、水质特性、受纳水体的环境功能及当地的实际情况和要求，经全面技术经济比较后优选确定。 1) the urban sewage treatment process should be selected according to the scale of treatment, the characteristics of water quality, the environmental function of the received water body and the local actual conditions and requirements, and after the comprehensive technical and economic comparison. 2) 工艺选择的主要技术经济指标包括：处理单位水量投资、削减单位污染物投资、处理单位水量电耗和成本、削减单位污染物电耗和成本、占地面积、运行性能可靠性、管理维护难易程度、总体环境效益等。 2) the main technical and economic indicators of process selection include: processing unit water investment, reducing unit pollutant investment, handling unit water consumption and cost, reducing the electricity consumption and cost of unit pollutants, covering area, reliability of operation performance, difficulty in management and maintenance, and the environmental benefits of the general body. 3) 应切合实际地确定污水进水水质，优化工艺设计参数。必须对污水的现状水质特性、污染物构成进行详细调查或测定，作出合理的分析预测。在水质构成复杂或特殊时，应进行污水处理工艺的动态试验，必要时应开展中试研究。 3) the quality of sewage influent should be determined and the process design parameters should be optimized. It is necessary to conduct detailed investigation or determination of the present situation of sewage, water quality and composition of pollutants, and make reasonable analysis and prediction. When water quality is complex or special, dynamic test of sewage treatment process should be carried out. Pilot study should be carried out if necessary. 4) 积极审慎地采用高效经济的新工艺。对在国内首次应用的新工艺，必须经过中试和生产性试验，提供可靠设计参数后再进行应用。 4) actively and prudently adopt the new technology of high efficiency and economy. For the first application of new technology in China, pilot and productive tests must be made, and reliable design parameters should be provided before being applied. |
