摘要：

The objectives of the study described in this paper were to study the requirements of potassium magnesium and calcium for enhanced biological phosphorus removal (EBPR) and to determine whether either potassium or magnesium could support EBPR on its own. Batch experiments indicated that phosphorus uptake by the sludge was affected by the availability of potassium magnesium, and calcium. Both potassium and magnesium were simultaneously required and neither was adequate by itself for EBPR. Calcium did not appear to be required for EBPR, and did not seem to be involved in biologically mediated chemical precipitation. (C) 1999 IAWQ Published by Elsevier Science Ltd. All rights reserved.
