Abstract
With the development of modern chemical synthesis technology, toxic and harmful compounds increase sharply. In order to improve the removal efficiency of refractory organic matter in waste water, the method of adding powdered activated carbon (PAC) to the system for adsorption was adopted. Through the analysis of organic matter removal rule before and after waste water treatment, it can be found that PAC is easy to adsorb hydrophobic organic matter, while activated sludge is easy to remove hydrophilic and weakly hydrophobic neutral organic matter. Powdered activated carbon-activated sludge SBR system (PAC-AS) system is obviously superior to AS and PAC system in removing organic matter of hydrophilic and hydrophobic components, that is, biodegradation and PAC adsorption are additive. Compared with the control system, the Chemical Oxygen Demand (COD) removal rate of refractory substances increased by 8.36%, and PAC had a good adsorption effect on small molecular weight organic compounds, but with the increase of molecular weight of organic compounds, the adsorption effect of PAC gradually weakened, and it had no adsorption effect on macromolecular organic compounds. Based on the research of fuzzy control theory, an Agent control system for ozone oxidation process of industrial waste water based on Mobile Agent Server (MAS) theory was established, which was realized by fuzzy control method. The simulation results showed strong stability and verified the feasibility and adaptability of the distributed intelligent waste water treatment system based on MAS theory in the actual control process.

In recent years, with the rapid development of economy, a large number of domestic industrial parks have emerged
Dilute the bacterial cake (2) When rice washing water was used as the primary matrix, with distilled water to prepare bacterial suspension with OD of the Chemical Oxygen Demand (COD) removal rate of refractory substances increased by 8.36% compared with the control system, while when glucose was used as the primary matrix, the COD removal rate only increased by 1.87%, indicating that rice washing water was better than glucose in co-metabolism primary matrix
In this paper, aiming at the time-varying and unstable system in the treatment process of toxic and refractory organic waste water, taking the aeration tank of the toxic and refractory organic waste water treatment system as the research object, the architecture of Mobile Agent Server (MAS) distributed intelligent control waste water treatment system is determined from two aspects of hierarchical structure and model structure, and the system is divided into two parts: control decision system and treatment control system
Summary
With the rapid development of economy, a large number of domestic industrial parks have emerged. It can be seen from the figure that the optimized adaptive fuzzy neural network control can achieve the control requirements faster than the traditional control method. The control method is applied to the simplified mathematical model formula (1), that is, when the substrate concentration is high and the growth rate of microorganisms is fast, the simulation experiment is carried out, in which each coefficient in the dynamic parameter value of the state equation is uncertain and
