This paper proposes to establish a CNC machine tool security system using artificial intelligence-based, and discusses the key technologies: the dynamic fuzzy neural network(DFNN), and based on this, describes an established security system of CNC machine tool.

A two-chambered MFC packed with activated carbon and used acrylic fiber wastewater as carbon source was constructed to study the electrical and anolyte change characteristics of the cell, the influence of activated carbon packing materials on electricity generation performance was analysed. The results indicated that microbial fuel cell could be upstart successfully when anaerobic sludge taken from wastewater treatment plants of acrylic fiber companies was used as inoculation; the maximum power density output of MFC was 211W/m3, and the internal resistance was 1311; N-contained aromatic compounds in anolyte was absorbed by activated carbon which made the cell could stably operated for a long time without renewing anolyte; anaerobic metabolism process was occurred in anode chamber, and during which N-contained aromatic compounds was degraded to amide, carboxylic acid, ammonia, etc.

By using the existing research experience and through the in-depth study of the harmonious society theory, this paper sets up a harmonious society index system. Moreover, based on this result and by making use of the method of AHP, this paper carries positive analysis on the construction of harmonious society of Beijing City.
