Sludge: 1L from aeration tank of existing aerobic treatment plant, check SV30 and MLSS, MLVSS.

污泥：1L 取自现有现有好氧污水处理厂曝气池，测定SV30， MLSS和MLVSS。

The MLSS was the rst large-scale study to compare surgical and nonoperative outcomes for lumbar disc herniation.

MLSS 是第一个比较腰椎间盘突出症手术与非手术治疗结果的大样本研究。

DO variation with temperature under the conditions of changing aeration rate, MLSS density and influent COD in the process of the organism degraded.

采用SBR法研究了不同曝气量、初始污泥浓度和进水COD质量浓度等条件下，有机物在降解过程中温度对DO变化的影响。

The relation of MLSS between the endogenous respiration rate and the maximum respiration rate are investigated and compared respectively based on activated sludge process.

以活性污泥为研究对象，分别测定了内源呼吸速率及最大呼吸速率同污泥浓度的关系，并进行了比较。

Compared with the conventional activated sludge process, the aerobic granular sludge has the advantages of high MLSS concentration, high settling velocity, and less land coverage.

与传统的活性污泥法相比，好氧颗粒污泥反应器具有MLSS浓度高、沉降速度快、占地面积小等独特优点。
