• 摘要：本文介绍一座新型氧化塘的研究和设计.该塘污水停留仅一天,表面负荷140g/m²·d.当原污水BOD₅为100mg/L、SS为120mg/L时,经初沉池分别去除30％和50％,至氧化塘出水BOD₅和SS均为30-40mg/L.经过各阶段试验和120m²/d中间试验均达到预期效果.现已用于广州大坦沙15×10m/d污水处理厂设计.

• Abstract：A new design of lagoon was proposed with a one-day retention time and a 140g BOD₅ per square meter surface area per day loading rate. When a wastewater with BOD₅ of 100mg/L, which has been pretreated by a primary settling tank (remove efficiencies for BOD₅ and SS were 30% and 50% respectively) was discharged into the lagoon, both BOD₅ and SS in the effluent of the lagoon were reduced to 30-40mg/L. The design was tested both in laboratory and on a pilot scale and has been adopted for construction of a sewage work with 150,000m3/d capacity in Datansa, Guangzhou.
