一道简单的关于污水处理的计算题
A high purity oxygen aeration system,is being considered for treatment of a
combined domestic and industrial wastewater.Since the combined wastewater
is high in soluble BOD and low in suspended solids,primary clarification is
not included in the processing scheme.The design flow is 3000 m-3 /d with an
average BOD of 300 mg/l.From previous experience in the aerobic treatment
of similar wastewater,the design F/M is 0.60g/d of BOD per g of MLSS and
the operating MLSS is 4000 mg/l.The maximum volumetric BOD loading is
2.5 kg/ m-3.d,minimum aeration period is 2.0h and minimum sludge age is 3.0
d.Based on these criteria,determine the volume of the aeration tank.Check
the validity of your answer with all the criteria given.
