In the design of Leachate equalization basin covering technology is introduced and the HDPE antiseepage geomembrane are used as the covering materials.

Simultaneously, it took the sanitary landfill project for example, calculated leachate generation and cubage of leachate equalization basin, and designed the floating cover to meet .

The domestic wastewater in one university is treated by the anaerobic hydrolysis acidification in the adjusting tank -CASS (Cyclic Activated Sludge System) techniques in the underground.

Two methods on design of water regulating tank are introduced and applied to the design of a sanitary landfill in this paper.

In this paper, the hydraulics problems of ship lock with regulating ponds are studied by mathematical model and physical model.

By use of regulating pond to grade the head of super-high-head-lock,the hydraulic head acting onthe culvert valves of lock can be reduced as half and the hydraulic problem on culvert valves can besimplified.
