According to the characters of aerobic-anaerobic coupled reactor (AAC) with effective treatment of wastewater and achievement of sludge reduction in tomato catsup processing,aerobic strains were isolated from the aerobic field of AAC,and 29 bacterial strains were obtained.

In this essay, An MPEG-2 AAC decoder is designed and verified using FPGA.

An FPGA prototype chip design of MPEG-4 AAC audio decoder is implemented.

The integrated MAP reactor was designed and the ammonia-nitrogen operation effect of MAP reactor was studied using MgCl2·6H2O and Na2HPO4·12H2O as precipitants.

At the same time, use FLUENT computational fluid dynamics simulation software to optimize the structure of MAP reactor.

On properties of granular sludge in EGSB reactor under oxygen-limited conditions;

Startup operations of the EGSB reactor;

Performance characteristic of the EGSB reactor in the microaerobic conditions;

Then comes to the MIC reactor for treatment of aldehyde.

The results suggested that COD removal rate could reach above 88 % under the conditions of anaerobic temperature of MIC reactor controlled at 35～39 ℃,pH v.

In the course of the reconstruction,the primary equipment of wastewater treatment was made use of,and MIC reactor was added in the back of the retention basin.
