Urban waste water treatment per province and river basin district

This table presents the most significant results of the annual survey Public treatment of urban waste water. The results are presented per province and river basin district (Rijn, Maas, Eems and Schelde) and include:
- number and capacity of the urban waste water treatment plants by type of treatment;
- the volume and concentration of organic matter, nutrients and heavy metals in the waste water running into waste water treatment plants (influent) and the volume of treated waste water (effluent). As of 2017, data on heavy metals are only inventoried for even years.
- the volume and destination of the sludge released, with nutrients and heavy metals. As of 2017, sludge data are only inventoried for even years.
Additional data on urban waste water treatment plants, process technology, energy consumption, generation of energy and sludge dewatering can be accessed on the Dutch version of StatLine.

Data available from: 1981

本表展示了年度调查《公共处理城市废水》的最显著结果。结果按省份和流域区域（莱茵河、马斯河、艾姆斯河和斯凯尔德河）进行展示，并包括以下内容：
- 不同类型废水处理厂的数量和容量；
- 进入废水处理厂的废水（进水）中有机物、营养素和重金属的体积和浓度，以及处理后的废水（出水）体积。自2017年起，重金属数据仅对偶数年进行统计；
- 排放污泥的体积和去向，包括其中的营养素和重金属。自2017年起，污泥数据仅对偶数年进行统计。
有关城市废水处理厂、工艺技术、能源消耗、能源产生和污泥脱水等方面的附加数据，可在StatLine的荷兰语版本中查阅。
