Проведена адаптация модифицированного процесса осаждения струвита к технологии очистки сточных вод сложного состава. Отмечено, что данная технология позволяет устранить существующий недостаток традиционной технологии, связанный с необходимостью использовать при осаждении струвита избыток ионов Mg2+, NH4+ или PO43-. Сделан вывод о том, что за счет использования модифицированной технологии осаждения струвита удалось повысить глубину очистки сточной воды от NH4+ и PO43- без использования их избытка до уровня 95 % и выше и обеспечить выход качественного продукта осаждения до 98–99 %.

Adaptation of the modified struvite precipitation process to wastewater treatment technology of complex composition was carried out. It is noted that this technology eliminates the drawback of the traditional method associated with the need to use an excess of Mg2+, NH4+ or PO43- ions. It is concluded that the use of the modified technology made it possible to increase the degree of wastewater purification from NH4+ and PO43- to 95% and higher without using their excess, and to ensure a yield of high-quality precipitate up to 98–99%.
