The settling basin for oncomelania snails is an important project measure in water conservancy project in combination with schistosomiasis control,which is a sort of construction used to sink and collect oncomelania snails.

Study on 1D layered and dispersive model for secondary settling tank simulation;

The simulation and the model of activated sludge process reactor with secondary settling tank;

One-dimensional dynamic models for secondary settling tank: a review;

Simulation and control of sludge blanket height in settling tanks;

Reynolds number of water flow in horizontal flow settling tank is above 3 000,and it is called turbulent flow.

The settling tank cost model is established by using it.

Computational fluid dynamic model for density currents in activated sludge secondary clarifier;

The first strategy is to keep sludge recycle flow unchanged; the second strategy is to have recycle flow increasing in the proportion of the system's influent flow; the third strategy is to control the variation of recycle flow with inflow to secondary clarifier in proportionality.

A novel suspended media clarifier was developed as a substitute for the secondary clarifier of conventional activated sludge process.
