Coke was modified as adsorbent for advanced treatment of coking wastewater and different factors on the impact of wastewater COD removal have been studied. The results showed that pH and temperature effect little on the COD removal and COD of coke wastewater could be reduced from 93mg/L to 48mg/L in the condition of 60 min adsorption time , 300r/min speed revolve and 13g adsorbent dosage. per 200ml water.

Competitive adsorption of phenol and Cr6+ in organic bentonite was studied in this paper. To solve the problem of multivariate nonlinear model of competition adsorption for Cr6+ and phenol on organic bentonite, MATLAB was used to process data to get parameter equation. The parameter equation fitting could explain competitive adsorption behavior of phenol and Cr6+ on organic bentonite. According to the fitting equation of 3D graphics,the result was deduced that the higher concentration of Cr6+, the lower the concentration of phenol. Phenol adsorption on organic bentonite is influenced by Cr6+.

This paper studied the adsorption of organic bentonite for phenol solution by changing the condition of organic bentonite dosage, phenol concentration temperature, adsorption time. According to the experimental results The system of BP neural network was evaluated by Matlab software to forecasting the complex nonlinear relationship between the amount of phenol solution concentration, adsorption time, solution temperature and remove rate of phenol, Experimental data used for the neural network model is more than 534 times of training. After training, the model achieves an accuracy of 0.0001. Finally, a group of test is forecasted by the data model. The results showed that predictive value and measured value of absolute error is only 0.0032 and0.0016. The predicted results show that in the system, a BP neural network model is evaluated successful..This template explains and demonstrates how to prepare your camera-ready paper forTrans Tech Publications.
