Study On The Treatment Of Rubber Accelerator Wastewater

It is difficult to treat the rubber accelerator wastewater to reach the standard by physical chemistry process, moreover the movement cost is higher; the rubber accelerator wastewater contains much non-degradability organic matter,bad biodegradability, as well as change in water flow and quality, therefore it is not very ideal to treat this wastewater by the bio-chemistry method. This paper has discussed this question and hope found the suitable method to dispose the rubber accelerator wastewater.In the laboratory stage, firstly, process the bacterium ridding, culturing domestication and identification; By the orthogonal experiment, it is determined the best culturing condition of the bacterium and the impact of the inorganic ions on the growth of bacterium; inspected the pH, temperature, salinity, Carbon and nitrogen to the growth of the super hybrid bacteria; study the degradation effect of the single bacterium at different temperatures, pH and the different concentration of rubber plant organic wastewater.Through the projection identify, super hybrid bacterium enhanced the A²/O process is selected to deal with the wastewater. Anaerobic treatment can increase the bad biodegradability of the wastewater. The biodegradability of the wastewater can be increased from 0.25 to 0.56. It is useful to the treatment of the follow-up process.It is simulated the processing treatment of the rubber wastewater in the laboratory. Firstly, it is domesticated the sludge active. Anaerobic reactor inoculated sludge from the treatment reactor of the leachate liquid of the garbage. The super hybrid bacterium added in the anoxic reactor and the aerobic reactor. Accordance with traditional culture methods, the anaerobic sludge is domesticated, and gradually increasing the COD_cr concentration of the wastewater, so that microorganisms can be gradually adapt to the wastewater and can be good at growing. It is taked about two months for domesticating. And the system into the start-up phase. In this phase, it is included water distribution and raw water start-up phase. In the stability operational phase, COD_cr, ammonia nitrogen and aniline average removal rate can be reached at 90.71 percent, 78.31 percent and 86.17 percent, respectively.
