Process technology parameters of sewage treatment plants. (from 01-01-1981)

This database contains the main process technology parameters of the biological treatment process at sewage treatment plants. The parameters in question are an indication of the load, functioning and energy efficiency of the biological treatment step.

The survey will be conducted on behalf of a number of other bodies, including Rijkswaterstaat, RIVM and the cooperation in the context of the Emission Registration. Mainly electronic survey. Reporters are all 23 regional water quality managers (water and purification boards).These organisations manage about 340 rwzi &s. ### Population Public sewage treatment plants (rwzi &s) at water boards or high-energy councils本数据库收录了污水处理厂生物处理工艺的核心工艺技术参数，此类参数可反映生物处理单元的负荷水平、运行状态与能源利用效率。 有关数据获取的详细信息，请参见： > https://www.cbs.nl/nl-nl/onze-diensten/maatwerk-en-microdata/microdata-zelf-onderzoek-doen ### 调研方法 本数据集基于荷兰水质管理人员综合调研生成。本次调研由荷兰公共工程与水管理总局（Rijkswaterstaat）、荷兰国家公共卫生与环境研究所（RIVM）及排放登记（Emission Registration）框架下的合作机构等多家单位委托实施，主要采用电子调研方式。受访对象为全部23家区域水质管理机构（水务与净化委员会），上述机构共计管理约340座污水处理厂（rwzi）。 ### 调研总体 调研总体为水务委员会或高能级理事会管辖的公立污水处理厂（rwzi）。
