Biosorption of organic pollutants, expressed as COD, by aerobic and anaerobic sludge was conducted to examine equilibrium and kinetic models. Freundlich and Langmuir models were mostly used for mathematical description of the biosorption equilibrium. Freundlich equation was more fit to describe the equilibrium of biosorption process in this study. Under the same experimental condition, biosorptive...
The study evaluated the sorption of Zn(II) ions from aqueous solution by two low-cost materials, waste somatic and dead tea fungus. The rate and extent of accumulation were affected by pH, contact time and initial zinc ion concentration. The initial removal was rapid and equilibrium was established in less than 30 min. Good correlation coefficients were obtained when the pseudo-second-order kinetic...
Mainly containing organic materials, the printing and dyeing wastewater is a kind of industrial pollution with complex composition and high colority, which is difficult to be treated. With the large volume of new auxiliary and slurry applied to the modern textile industry, the biodegradability rate of organic pollution decreased and it is more difficult to be treatment. Comprehensively considered...
The bio-hydrogen producing process has complex interactions; thus, constructing a detailed mechanistic model and proper control architecture is difficult. Artificial neural networks (ANNs) are capable of inferring the complex relationships between input and output process variables without a detailed characterization of the mechanisms governing the process. This work presented a novel ANN that accurately...
Trichloroethene (TCE), usually in the form of dense non-aqueous phase liquid (DNAPL), is a widely used degreasing ingredient causing profound soil and groundwater contamination. While bio-enhanced dechlorination of TCE to harmless Ethene is a promising technique for waste water treatment, the mechanism and related phenomenon have not been thoroughly understood, especially in groundwater. A comprehensive...
At present, activated sludge model has great value and can be used to improve the study, design and optimum operation of wastewater treatment around the world. It has been applied widely in the world. In this paper, the application and calibration of Activated Sludge Model No.l in the practical wastewater treatment plant had been implemented. The characterization and parameter of the outfluent from...
The purpose of this work was to investigate the kinetics of the adsorption and biodegradation process in adsorption-biodegradation anaerobic sequencing batch reactor (AB-ASBR). Using the whole milk powder as substrate, the volume loading rate (VLR) of influent was 7.0kgCOD / (m3 · d) at 35°C. In order to maintain the optimal pH value, NaHCO3 was added into the influent. The experiment indicated that...
Establishment concentrate distributed mathematical model of the whole tower under the condition of continuous foam separation with SDS as active agent , and the effect of the wastewater of Cr (III) to remove in different feeding high. The model has been tested by experiments. The Results indicated that the model is consistent with the data of experiments to a considerable degree.
