Stabilization Characteristics of Deposits of Biologic Solids Generated in Aerated Lagoons

摘要

Properly-designed dual-power-level multicellular lagoon systems should discharge effluents low both in suspended solids and biochemical oxygen demand. Solids that settle form deposits in which bio-degradable materials decompose in a benthal environment. The present laboratory study investigated the rates of benthal stabilization, and was unique in that it was conducted on a deposit formed at the bottom of an aerated water column that was primarily organic under conditions in which aerated lagoon solids were added on a semi-continuous basis. Such studies were needed to develop criteria for the sizing of lagoon cells and the specification of aeration equipment.
