无数实践结果表明,曝气池设计中必须抓住主要环节,认真搞好水、气、泥三个方面的平衡。水的平衡:就是要根据污水水质,正确求得污泥负荷和污泥浓度,计算曝气池容积,确定曝气池建设规模;气的平衡:就是要根据污水水质和处理要求,计算供气(供氧)量,确定供气(供氧)设备能力; Numerous practical results show that the aeration tank must be designed to grasp the main links, and do a good job in balancing water, gas, and mud. Water balance: It is necessary to correctly obtain the sludge load and sludge concentration according to the sewage water quality, calculate the aeration tank volume, and determine the aeration tank construction scale; the gas balance is to calculate the gas supply according to the sewage water quality and treatment requirements. (Oxygen supply) quantity, determine the capacity of gas supply (oxygen supply) equipment;
