Method and design for the removal of crop protection agents from waste streams of the agricultural sector in general and greenhouse horticulture in particular

摘要

The present invention relates to a method or device for removing crop protection agents from waste streams of the agricultural sector in general and greenhouse horticulture in particular, characterized by a purification process carried out batchwise whereby the liquid to be purified is at least partially pumped through a purification plant, over a buffer vessel. , which is an integral part of the purification process, is recirculated and consequently, at least partly, pumped more than once through the treatment plant. The purification process consists at least of a synergistic combination of oxidation by means of hydrogen peroxide in the presence of iron and / or iron ions and a ultrasound-assisted treatment with UV-C radiation.
