The Discussion of Altitude Influence on the Aeration Rate of Domestic Wastewater Treatment Plant
Our country region is wide,the average altitude's span is large,with the increase of altitude the oxygen and pressure become more lower,it has an obvious influence on the standard oxygen transfer rate and aeration rate of wastewater treatment plant.This article combines with relevant engineer,through calculation and verification the biochemical pool's real oxygen demand、standard oxygen transfer rate and aeration rate of altitude 0,500,1000,1500,2000,2500,3000,3500,4000,4500,5000 m.The result indicate that,with the increase of altitude,the aeration rate increase with the D-value between corrective oxygen pressure and not correct;the altitude has no influence on the real oxygen demand;the standard oxygen transfer rate and aeration rate have exponential relationship with altitude,in high altitude area,the increase of the standard oxygen transfer rate and aeration rate grow multiply,it has marked difference with plain area.This finding also can be helped with the biochemical pool's aeration calculation and equipment selection of the relevant plateau area.
