摘要
以柠檬酸废水为研究对象，研究了预酸化度对上旋流厌氧反应器处理性能的影响。研究结果表明，预酸化度对上旋流厌氧反应器系统的COD去除率、出水VFA、污泥增长量、产气量有明显的影响。随着预酸化度的提高，可以提高厌氧系统的COD去除率，降低出水VFA，增加沼气产量，但降低了颗粒污泥增长的速度。在实际工程应用中，控制预酸化度在20％～30％可以保持厌氧系统稳定高效的COD去除效果，同时保证颗粒污泥的快速增长。
Using citric acid wastewater as the research object, the effects of pre-acidification degree on performance of the vortex flow anaerobic reactor were studied. The experimental results showed that pre-acidification degree had obvious effect on COD removal rate, effluent VFA, the growth of sludge, biogas production. As the pre-acidification degrees higher, could improve the COD removal rate, reduce effluent VFA, increase biogas production, but reduce the granular sludge growth rate. Control pre-acidification degrees for 20% -30% in the practical engineering application, COD removal rate of anaerobic system could keep stable and efficient, at the same time ensure that the rapid growth of the granular sludge.
