This article presented a new fast algorithm of Moore-Penrose inverse for an m×n symmetric Loewner-type matrix with full column rank by forming a special block matrix and studied its inverse. Its computation complexity was O+O(n^2), but it was O(mn^2)+O(n^3) by using L(superscript +)=L(superscript TL^(-1)L.

According to the above study results, especially the steady operation of two-sludge system(2A/O+N 2SBR), it can be proved that denitrification and excess phosphorus uptake are relatively independent and intersectant biological processes. The overlap is that denitrifying phosphorus removing bacteriawhich possesses the two bacterial metabolisms, could utilize nitrate as an electron acceptor for phosphorus uptake. The two-sludge system can not only combined biological phosphorus removal and denitrification processes to form a process in practical wastwater treatment , but also solved the main difficulties of current single-sludge systems:①the sludge age competition between phosphorus removing bacteria and nitrifier;② the substrate competition between denitrification and dephosphatation.

以上的研究结果,尤其是时间序列的双泥生物反硝化除磷脱氮系统工艺(2A/O+N 2SBR法)的稳定运行,不仅证明了生物脱氮与生物除磷是两个既相对独立又相互交叉的生理过程,其交叉点是同时拥有硝酸盐还原性和超量吸磷这两种生化特性的细菌进行的反硝化吸磷脱氮生化反应,而且双泥系统工艺克服了常规单泥生物脱氮除磷工艺的两大问题(①聚磷菌和硝化菌的SRT相互干扰;②反硝化与生物除磷竞争VFA),同时保证了脱氮和除磷效果,排水指标达到污水综合排水标准(GB8978-1996)的一级标准,具有实际工程使用价值。
