Mathematical statistical method (MSM) is a very important wastewater treatment plant data processing analysis tool. In this study, MSM had been used to evaluate the efficiency, stability and reliability of the low-strengthen complex wastewater treatment system. Results showed that while LSCWWTs upgrading in the future, each influent parameter could be set as the follows: COD = 738 mg/L, BOD = 300 mg/L, SS = 454 mg/L, TN = 64.3 mg/L, NH3-N = 65.2 mg/L and TP = 7.65 mg/L. For effluent of LSCWWTs, the stabilities of COD, BOD, SS and TN were all A, TP was B, and NH3-N was D. For effluent COD, TN and NH3-N reached the first class discharge standard of A, the reliability probabilities were 83.89%, 80.23% and 99.43%, respectively. And the reliability probabilities of effluent WQPs reached the first class discharge standard of B were all more than 98%.

Mathematical modeling and simulation technology is a very important wastewater treatment plant data processing analysis tools. To analysis the wastewater treatment plant operation process, this study was realized on MATLAB and LIB-SVM tools. Determine the five feed water quality indexes (water inflow, pH, temperature, COD, MLSS) as input variables and the effluent COD concentration as output variable. Within the SVM modeling, through the GA algorithm, PSO algorithm and the grid search method to separately carried on the model parameters optimization. Through the verification results show that SVM model predicted the COD concentration average relative error is 0.0165, which has higher accuracy, which can meet the actual requirements of water quality prediction.

This study investigate the influence of different 7-ACA concentration of pharmaceutical wastewater on microbial activity of activated sludge, the studies show that under the different influent 7-ACA concentrations, the corresponding 7-ACA concentrations of the highest value of urease and SOD activities are 0 mg/L, DHO and nitrate reductase are 50 mg/L, inverting enzyme is 40mg/L, PPO is100 mg/L. the study also show that with the increase of intermediate concentration of pharmaceutical wastewater, microbes product β-lactamase enzyme under the stimulates of 7-ACA and the activity of β-lactamase enzyme increased and then decreased. The activity of β-lactamase enzyme observed of the highest 1212.9U and the best removal effect on 7-ACA when the concentration of 7-ACA is 30mg/L. The optimal pH, temperature and DO of the microorganism product the β-lactamase enzyme were 8, 35 ° C, and 2.5 to 3.5mg/ L.

There is a certain amount of intermediate and other ingredient in pharmaceutical wastewater .These pharmaceutical will have a big effect on microorganism in sewage treatment plant. So this article discussed the study one impact of microbial community structure by the different intermediate concentration of Pharmaceutical waste water .The study shows that Microbial community structure are diversity in the pharmaceutical wastewater treatment plant.With the change of the environment some microbes are reduced or even disappear and some microbes are gradually produce. The microbes which have a big effect by different environment have adapt to 7-ACA, won the resistance and become a part of microbial community in stationary phase.

The polar glass-ceramics of 2.0SrO-1.0TiO2-2.9SiO2 system were prepared by the process of recrystallization with additional applied isothermal and electric field. The results showed that the glass-ceramics piezoelectric constant d33 was 12×10-12 C/N. The study of its oriented crystallization by SEM and XRD indicated that Sr2TiSi2O8 crystal performed oriented growth, which was perpendicular to the glass surface and made it be orientally crystallized with the assisted the isothermal and electric field. The further experimental results showed that the additional electric field reduced the crystallization activation energy, which provided a force for the isothermal orientating crystallization process.
