试析制浆造纸工业污水中的硫酸盐对厌氧处理的影响及对策
摘要
When anaerobic treatment of pulp and papermaking industry wastewater, the sulfate contained in it is reduced to hydrogen sulfide, which will have a strong inhibitory effect on methane bacteria and reduce the effect of anaerobic treatment. In order to avoid this situation, effective measures should be taken to reduce the influence of sulfate on anaerobic treatment. Based on the principle of anaerobic treatment of pulp and papermaking industry wastewater, this paper analyzes the harm of sulfate and the influence of reduction in the process of anaerobic treatment, and from the control of sulfate concentration, strengthen sludge acclimation, improve anaerobic process and other aspects, put forward some effective countermeasures, hoping to play a reference role.
