Computer models for analysis of wastewater treatment

摘要

Modelling is an inherit part of the design andanalysis of wastewater systems. Computur simulation permitsthe examination of performance of large works with a timesaving compared to tradational approaches. The disadvantage ofsimulation programs are that the results are not good asexperimental studies. Realising the benefits to be gained frommathematical modelling, the International Association on WaterPollution Research and Control Group (IAWPRC) proposed toshow the performance of wastewater treatment plants, includingcarbonaceous removal, nitrification and denitrification. Themodel is also useful to use for existing wastewater treatmentplants by modification of plant according to new conceptsrequired by wastewater authorises. IAWQ (formerly IAWPRC)Task Group for mathematical modelling for design andoperation of biological wastewater treatment introduced theActivated Sludge Model 1 has become a major reference forfurther research work and is the basis for many softwarepackages applied to design and operation of treatment plants.This paper deals with the use of existing simulation models forprimarly ammonia nitrogen removal.
