Abstract

Сточные воды, содержащие селен в растворимой форме, обрабатывают в биореакторе (14). Микроорганизмы в реакторе восстанавливают селен до элементарного селена, который является нерастворимым. Элементарный селен выгружают из реактора с удаляемым избыточным илом. Удаляемый избыточный ил сгущают и затем обрабатывают реагентом для лизиса клеток, чтобы разрушить или растворить клетки микроорганизмов в иле. После лизиса ил обрабатывают, чтобы физически отделить оставшиеся твердые вещества, которые включают элементарный селен, для повторного использования.
