摘要
为了考察石油进入SBR工艺城市污水厂后对污水厂造成的影响,选择石油产品同城市污水处理常用的SBR工艺为对象,并通过试验验证了利用污水厂强化去除油污染的可行性,从而为运用SBR工艺处理突发性石油污染提供决策参考和科学依据.试验结果表明:SBR工艺可以有效抵抗50mg/L含量的石油污染冲击,有机物、氮和油含量均可实现达标排放;在100mg/L与200mg/L含量的石油污染冲击下,出水COD和石油含量等重要指标出现超出国家标准情况,需结合其他手段进行强化处理.SBR工艺可承受一定程度的石油污染冲击,其除油主要是通过污泥的吸附作用.
In this study, petroleum products and a typical SBR wastewater treatment plant were chosen to investigate the impact of episodic petroleum pollution accident on the performance of wastewater treatment of the plant. The feasibility of using wastewater treatment plant to remove oil pollution was investigated. The experimental results show that SBR wastewater treatment plant can effectively resist the impact of 50 mg/L oil poilu, tion and the effluent water quality reaches the national discharge standards. However, the COD and oil concentrations are over the national discharge standards when the oil impact concentration is higher than 100 mg/L. In such a case, other technical methods combined with SBR are needed to enhance the treatment efficiency. SBR wastewater treatment plant can resist the effect of oil pollution when the petroleum concentration is within a threshold value.
