The dephosphorizing effect by a series filtration, repulping (acidulation) and water washing process in WPA production is studied.
对湿法磷酸生产流程中串联再浆(酸化)水洗的降磷效果进行了实验研究。
The equipment described in this paper as a kind of sewage treatment device possesses the advantages of both hydrolytic acidulation and biological contact oxidation.
本设备集水解酸化和生物接触氧化两者优点于一体,是一种处理生活污水的中小型装置。
In the production of nitrophosphates by the mixed acid process the main components of the acidulation tail gas are nitrogen oxides, and the steam condensate from evaporation contains ammonia.
