对邻苯二甲酸二(2-乙基己基)酯(DEHP)对污泥好氧消化的影响进行了研究,以期为污泥的安全资源化和J用提供一定的基础资料。结果表明,对于污泥好氧消化,当进泥中DEHP投加量为20mg/L时,对VSS去除率没有明显影响;当DEHP投加量为100mg/L以上时,随DEHP投加量的增加,VSS去除率下降,同时反应器污泥中DEHP的残留浓度随之增大。
The effect of DEHP on aerobic digestion of sludge was studied in order to provide basic data for safty resources utilization of sludge. The results showed that, it had no effect on removal rate of VSS when the applied dose of DHEP in influent sludge was 20 rag/L, when the applied dose of DEHP was above 100 mg/L, with the increase of DEHP dosage, the removal rate of VSS decreased and the residual concentration of DEHP in the reactor increased.
