摘要：

Granulation of the sludge is an essential requirement for the satisfactory operation of UASB reactors. This study examines the effect that nutritional deficiencies have on the initial performance and granule formation. Ten UASBs were operated for 92 days as five pairs with each pair receiving a different feed. The nutrients examined were phosphorus, magnesium, calcium, and trace elements. The results show that deficiencies in magnesium, calcium, and trace elements appeared to affect the performance of the methanogens and that deficiencies in all the nutrients examined adversely affected granulation. © 1990.
