The Study On The Wastewater With High Level Concentration Of Sulfate By ASBR

The water pollution is very serious in China now, which the sulfate pollution is predominant factor to contribute to it. Then it is urgent to solve the problem of sulfate pollution. The researchers are paying increasingly attention to the technique of the SRB (sulfate reduction bacteria), which is very potential.The Wastewater of sulfate are ready to degradation pH.to the water , acid the soil, and increase the concentration of heavy metal. All of these effect our environment. The influence of pH, temperature, C/S, microelement etc. are studied in the treatment on the waste water of sulfate. In order to achieve the best result of the treatment, the good parameter are found in the experiment. In the same time we make effort to improve the reactor.At the same time we discuss the competent between the SRB and MPB. Anaerobic Sequencing Batch Reactor(SRB) was a high efficient reactor which was designed recently yeas. The character and the development was discussed and Single Chip was used to realization the control system. Then, in the laboratory-scale study two parts of work was done. The different variations of the sulfate concentration under the different parameters of PH, temperature , COD/SO42- are given out and choosed, especially some results by using the TiO2 -producing wastewater were given out. At last the principle of the SRB's behaviors were discussed and a model about it was given out and was also used to solve some problems that sulfate reduction leads to.
