The prediction and control for sludge acidogenic fermentation process has a guiding role for the biological treatment of acid mine drainage with SRB to select proper carbon source. Two mathematical models were used to predict sludge acidogenic fermentation process with semi-continuous operation mode. The results showed that quadratic polynomial regression model is superior to multivariate linear regression...
A new method of microorganism acclimation for biological treatment of high-salinity oilfield wastewater was proposed, in which the salinity was increased in logarithmic mode, while in the traditional method the salinity was mainly increased in proportion. A contrast experiments was made between new method and the traditional method. The quality of the influent is as follow: salt content was ranged...
The aim of the investigation was to evaluate the nitrogen removal efficiency by using the combined partial nitrification and anaerobic ammonium oxidation (anammox) process for high-strength ammonium synthetic wastewater. The partial nitrification and anaerobic ammonium oxidation reactors were inoculate with domesticated sludge and operated respectively during the startup period. Subsequently, they...
O-nitrobenzaldehyde (ONBA) manufacturing wastewater not only contains significant amount of oil-like substance, but also high salinity, total nitrogen (TN) content and concentration of dissolved organics resulting in high COD load. Oil-like substance could be removed from the wastewater by physical methods. However, dissolved COD compounds and TN could only be removed by biological or chemical treatments...
The concentration of selected malodorous compounds dissolved in water in different unit processes of actual treatment plant, and in different location of small scale treatment plants (Jokasos) were identified in order to provide sufficient information to undertake proper action to solve the problems of malodor compounds in water environment and in wastewater reuse. Analytic methods to measure as low...
