摘要
磷是水体富营养化的一个主要限制因素,控制出水中磷的浓度尤其重要。污水除磷方法有生物除磷、化学除磷及生态除磷,也可将各种方法组合使用,如生物-化学除磷、生物-生态除磷等,实际应用中应根据具体情况选择适宜的除磷方法。
Phosphorus is a limiting factor of eutrophication, so it's very important to control the content of phosphorus remval in (effluent). Methods of phosphorus removal include biological process, chemical process and ecological process. These methods can also be combined, such as bio-chemical phosphorus removal process and bio-ecological phosphorus removal process. In practical application, phosphorus removal process should be selected according to concrete (conditions).
