By means of setting up an anaerobic tank in front of DAT-IAT, biological degradation performance and phosphorus removal efficiencies are studied with municipal sewage.

The combined system of anaerobic tank/constructed wetland/biological pond was applied to treat the cows farm wastewater.

The authors verified and revised the kinetic model of the anaerobic filter proposed by Yong & Mccarty (1968).

For improving the processing efficiency of anaerobic filter,natural pumice,natural zeolite, plastic porous hollow ball and magnet blocks were adopted to make three different kinds of biocarriers including spherical pumice biocarrier,magnetic spherical pumice biocarrier and spherical zeolite biocarrier.

Solid phase extraction-LC/MS/MS detection method was applied to study the concentrations and sludge adsorptions of nine estrogenic endocrine disruptors(EEDs) in an upflow anaerobic sludge blanket(UASB) and an anaerobic filter (AF).

The primary processes included: depilating with hydraulic screen,degreasing with pre-grease setting tank,pre-aerating balance tank,anaerobic ABR reactor,bio-contact oxidation reactor and deposit,etc.

Sewage treatment with the combination of an anaerobic fixed film reactor followed by a high rate trickling filter without re circulation was investigated.
