先进的污水处理装置用以去除经过机械处理和生化处理仍然存在于污水中的有害物质。目前,注意力集中于去除悬浮物、磷酸盐和氮化合物。这三种物质中那一种是主要的,视其浓度而定,此外,在一定程度上,决定于地区条件。在瑞士,着重去除悬浮物和磷酸盐;在西德,先进的污水处理旨在去除悬浮物;在英国,首先去除氮化合物。现今,试图将净化处理工艺中的化学系统综合化,以改善出水参数,可以在一定程度
The advanced sewage treatment device is used to remove the harmful substances that still exist in the sewage after mechanical treatment and biochemical treatment. At present, attention is focused on removing suspended matter, phosphates, and nitrogen compounds. Which one of the three substances is the main one, depending on its concentration, and, to a certain extent, on the regional conditions. In Switzerland, emphasis is placed on the removal of suspended solids and phosphates; in West Germany, advanced sewage treatment is designed to remove suspended matter; in the United Kingdom, nitrogen compounds are first removed. Nowadays, trying to integrate the chemical systems in the purification process to improve the effluent parameters can be
