Method for improving activity of nitrification function microbiology in activated sludge through directly feeding Fe ions

The invention provides a method for improving the activity of nitrification function microbiology in activated sludge through directly feeding Fe ions, which comprises a cultivation stage of the nitrification function microbiology and a long-time running activity maintenance stage. In a saprobiont denitrification system, ferric salt chemical agent with Fe <2+> or Fe<3+> is directly fed into an activated sludge mixture of an aerobic pond of a biology denitrification system, and basic compounds are also fed simultaneously; and in the long-time running activity maintenance stage of nitrificationfunction microbiology, the feeding amount of the ferric salt chemical agent with the Fe <2+> or the Fe<3+> is gradually reduced, and the fed ferric salt chemical agent with the Fe <2+> or the Fe<3+> is only used for replenishing loss amount of the Fe<3+> or the Fe <2+>. According to the method, the biochemical reaction metabolic activity of the nitrification function microbiology can be effectively improved, the breeding of the nitrification function microbiology and the secretion of endoenzyme of microbial cell are promoted, the applicability of saprobiont denitrification technology is improved, the bottleneck problems existing in the saprobiont denitrification system are solved, and the low temperature resistant capacity of the system is obviously improved.

Method and device for running control of application programs

The invention provides a method for running control of application programs. The method comprises the steps that an installation package which has the same package name with a host application program and is taken as an attached resource of the host application program is reflected and called, and a target application program implemented by the installation package is loaded, wherein resources required by the target application program have a one-to-one correspondence relationship with resources required by a native application program; a hook function is used to monitor activity processes of the target application program; and when the hook function monitors a calling instruction towards the activity processes of the target application program, the resources which are required by the native application program and have a one-to-one correspondence relationship with the resources required by the target application program can be called. The invention also provides a device for the running control of the application programs. By execution of the relevant resources of the target application program, an execution result which is completely the same with an execution result obtained by execution of the relevant resources of the native application program can be obtained; and the target application program is operated in a sandbox which is established by the host application program, so that installation and running activities are not sensed by a system.
