摘要：合理确定污水厂污泥产量是设计污泥处理系统的基础,从设计角度对预处理污泥、剩余污泥和化学污泥产量现有计算公式进行讨论,对重要参数如预处理污泥产量公式中系数α、出水SS,剩余污泥产量公式中污泥产率系数Y、污泥转换率f,化学污泥产量公式中药剂转化泥量系数K、进出水溶解性总磷的取值进行了分析。针对剩余污泥计算公式中污泥龄θc取值较宽泛的问题,提出了以磷平衡法进行校核。此外,还提出了当θc>20 d时,Y应以可生物降解COD(BCOD)为计算基础;同时建议《室外排水设计标准》在修订剩余污泥计算公式时,应考虑活性污泥内源呼吸过程中的惰性残余物。建议重力浓缩进泥含水率取99.2%,水力停留时间取12~16 h以免厌氧释磷;进泥管路上投加聚合氯化铝(PAC)或池底曝气以降低上清液TP浓度。常规污泥浓缩、调理及超高压板框压滤脱水工艺能将污泥含水率降至55%左右,进一步降低含水率需在脱水后增加干化环节。

摘要：An optimized compound 9-(9,9-dimethylacridin-10(9 H)-yl)-6 H-benzo[c]ch-romen-6-one(MAB) was designed and synthesized based on our previously reported TADF emitter 6-(9,9-dimethylacridin-10(9 H)-yl)-3-methyl-1 H-isochromen-1-one(MAC) to further improve the performance of thermally activated delayed fluorescence(TADF)emitters. With the additional phenyl in coumarin-contained plane, MAB possesses an extended distribution of the lowest unoccupied molecular orbitals(LUMO), and thus realizes reduced electron exchange between the frontier molecular orbitals and a stretched molecular dipole moment compared with MAC. MAB based organic light-emitting diode(OLED)exhibits a remarkable maximum external quantum efficiency(EQE) of 21.7%, which is much better than the maximum EQE of MAC-based OLED with a value of 12.8%. Our work proves that extending the distribution of LUMO is a simple but effective method to improve the efficiency of TADF emitter.
