摘要
在处理炼油废水的SBR装置中加入一种生物促进剂和毒性缓冲剂,在投加量均为7mg/L的条件下,与未投加生物促进剂时相比,出水COD的去除率增加约50%,挥发酚由20mg/L降至4.9mg/L,污泥浓度由3.9g/L提高到4.9g/L,污泥絮体增大,结构紧密。
A biological accelerating agent with toxicity buffering agent was added to a SBR unit handling refinery wastewater.When the dose was7mg / L and compared to the rate obtained without the addition of any biological accelerating agent,the COD removal rate of the outlet water increased by about50%,the content of volatile phenol decreased from20mg / L to4.9mg / L and the concentration of sludge increased from3.9g / L to4.9g / L,while the sludge flocs became bigger with compact structure.
