The results of continuous experiments with BAF show that: the short nitrification occurs when the Qair/Qinfluent ratio is 4:1 with NO_2~--N accounting for 72% of NOx--N; the suitable recirculation rate is 200%; the ratio of external acetate dose to NH4+-N concentration is 2:1 attributing to the short nitrification; BAF needs being backwashed when the headloss increases to 6 cm every 17~20 days; in the water reuse context, 98.7% water yield can be obtained.Lastly, the long-term operation of SBR-BAF system indicates it can treat the wastewater efficiently.

The essential problem of KBOOA are acquirement and organization of knowledge about the application domain. First of all, we recognize objects according to their outside characteristics and build stable concepts structures. In this way, the attributes and behaviors of any objects are treated as objects as well. The concepts are organized in hierarchies, the concepts' semantics are demostrated in the form of conceptual graphs. As hierarchy structure has inheritance, the system has ability to recognize and reuse concepts, analyze and reason the acquired information according to the existing knowledge, understand the problem space and present the system's functions and characteristics to the analysts and users in the form of scenarios. The main means of transforming informal requirements to formal ones is to recognize objects according to their outside characteristics, recognize attributes according to their functional dependence and describe the semantics of objects, behavior and attribute's relationship's because there is a automatic map from the descriptions of attributes and behaviors to class structures. It is difficult to transfer from OOA to OOD, We disscussed the modularity of Object-Oriented programs according to the principles of software engineering and presented the methods to decrease couplings and increase cohesions, i.
