Abstract

Способ и установка для извлечения фосфата из материала биомассы, причем материал биомассы может быть отработанным активным илом из расположенного выше по течению процесса очистки сточных вод, включающего биологический способ удаления P. Способ включает стадию анаэробной ферментации и стадии получения независимых потоков с высоким содержанием PO4 и Mg или с высоким содержанием PO4 и NH4, за счет чего увеличивается количество извлеченного P и исключается образование струвита в анаэробном ферментере и вспомогательном оборудовании, таком как трубы.A method and apparatus for recovering phosphate from biomass material, wherein the biomass material may be spent activated sludge from an upstream wastewater treatment process comprising a biological removal method P. The method includes an anaerobic fermentation step and steps for producing independent streams with high PO4 and Mg content or high PO4 and NH4 content, thereby increasing the amount of P recovered and avoiding the formation of struvite in the anaerobic fermenter and auxiliary equipment such as pipes.
