A method and process for the treatment of wastewater containing phosphorous and nitrogen. The wastewater is first anaerobically treated to produce an anaerobic effluent from which insoluble organic carbon is separated to form a sludge rich in organic carbon that is used as a substrate during anoxic treatment of the wastewater by de-nitrifying phosphorous accumulating organisms (DPAO's) and ordinary de-nitrifying organisms. The separation of insoluble organic carbon is normally conducted using a clarifier located intermediate the anaerobic and anoxic bio-reactors. In one embodiment, the ammonia rich clarifier supernatant is directed to an aerobic reactor for nitrification and the nitrate produced is recycled to the anoxic bio-reactor. The final effluent may be membrane filtered to retain nitrifying biomass within the aerobic bio-reactor. The invention reduces overall hydraulic residence time and sludge volume, which results in a smaller, less expensive wastewater treatment system.

A method for controlling random access is provided, and the method includes that an access network element sets multiple random access backoff values according to the various types of the terminal classification; the access network element transmits a Random Access Response Media Access Control Protocol Data Unit (RAR MAC PDU) to a terminal, and the RAR MAC PDU contains the information of the random access backoff value set according to the classification; and according the type of the terminal itself, the terminal looks up the corresponding random access backoff value in the RAR MAC PDU to perform the random access delay processing. A system for controlling random access is also provided. With the present invention, the access collision probability of the terminal can be decreased enormously.

The invention discloses a MapReduce optimizing method suitable for iterative computations. The MapReduce optimizing method is applied to a Hadoop trunking system. The trunking system comprises a major node and a plurality of secondary nodes. The MapReduce optimizing method comprises the following steps that a plurality of Hadoop jobs submitted by a user are received by the major node; the jobs are placed in a job queue by a job service process of the major node and wait for being scheduled by a job scheduler of the major node; the major node waits for a task request transmitted from the secondary nodes; after the major node receives the task request, localized tasks are scheduled preferentially by the job scheduler of the major node; and if the secondary nodes which transmit the task request do not have localized tasks, prediction scheduling is performed according to task types of the Hadoop jobs. The MapReduce optimizing method can support the traditional data-intensive application, and can also support iterative computations transparently and efficiently; dynamic data and static data can be respectively researched; and data transmission quantity can be reduced.

The heavy oil and residual oil hydrotransforming catalyst has siliceous alumina carrier, relatively strong acidity and especially protonic acid amount higher than that in available residual oil hydrotransforming catalyst. The siliceous alumina carrier is prepared through one colloid forming process, during and after which silicon is added to make alumina possess more strong acid centers and ideal pore structure. The catalyst of the present invention is used in the hydrotransforming treatment of heavy oil, residual oil and other inferior oil material.

The invention relates to a multi-business supporting network switching device and an implementation method therefor. The device employs a multi-level CLOS switching configuration, and an input unit, an output unit and a switching unit are respectively provided with a buffer memory. The device can process a multi-business flow, and can achieve switching according to the business characteristics. The device can generate quick flow control in a congestion scene through the output unit, wherein the quick flow control acts on an input end, thereby reducing the congestion stress on the output end, and reducing the congestion degree of a central level. The device can reduce the input flow of a fault plane in a link fault scene through a load balancing scheme, and alleviates the congestion of the switching unit. An output unit package ordering method is employed, thereby reducing the design complexity of the switching unit. A data package cell load balancing method of the input unit is employed for enabling the time difference among cells to be small, thereby reducing the time delay of a data package, and reducing the size of the ordering and recombination buffer memory of an output end.

In a storage area network (SAN), different tasks may expect different types of commands for commencing execution, such as interactive or offline, and may have different formats for reporting status and completion, such as log files or message based. A framework for defining the business logic enveloped in a particular task, and providing a common manner of deploying, or enabling invocation, of the task provides consistent operator control for scheduling, monitoring, ensuring completion, and tracking errors and other events. Business logic modules are identified as commands corresponding to a task. Transactions including a set of the commands define an ordered sequence for completing the task. The operator requests a particular set of tasks, using a selection tree, and the task manager builds a corresponding execution tree to identify and map the transactions and commands of the task to the execution tree to optimize execution and mitigate redundancies.
