DWA-A 131CN- Activated Sludge Plants (chinese)


Standard DWA-A 131CN - Dimensioning of Single-stage Activated Sludge Plants - June 2016 (Chinese translation August 2022)


Using the dimensioning values recommended in this Standard, the minimum requirements for municipal wastewater with single-stage activated sludge plants can be met or bettered at national level. In contrast to earlier
editions, in which the dimensioning procedure for nitrifying and denitrifying activated sludge plants was based
on the measured BOD5 load, the design is now based exclusively on the COD load.

Standard DWA-A 131 deals not only with the description of the process, the design procedure and the design
bases, but also with the calculation of the mass of the sludge and the design of the secondary treatment and
sludge activation. In addition, planning and operational aspects are dealt with and the possibility of simulation,
e.g. scenario comparisons or the consideration and quantification of the effect of further automation functions
and operational management concepts, are explained.

The Standard is aimed at operators of wastewater treatment plants, planning engineers and approving authorities.
