高浓度活性污泥法处理化工园区综合废水研究

Study on the treatment of mixed wastewater in the area of Chemical Industrial Park by highly concentrated active sludge process

介绍了高浓度活性污泥法处理化工园区综合废水的现场实验。探讨了高浓度活性污泥法在不同污泥CODCr负荷以及不同进水CODCr下对化工园区综合废水的CODCr的去除率及其污泥性状。实验表明,在0.30～0.40kg/(kg·d)的污泥CODCr负荷区间内,CODCr的去除率可达90%以上;在一定范围内较低的进水CODCr对进一步降低出水CODCr帮助不大,反而会降低系统对污染物的去除率。

The experiments of the treatment of mixed wastewater in the area of Chemical Industrial Park by highly concentrated active sludge process are introduced. The CODCr＇s removal rate of mixed wastewater, which has different CODCr loading of sludge and different CODCr concentration of influent water, being treated by highly concentrated activated sludge process and its sludge charactristics are disussed. When the CODCr loading range of sludge is 0.30-0.40 kg/（kg·d）, the removal rate of CODCr could be over 90%. In a certain CODCr range of influent water, the CODCr of influent water with lower influent concentration does not help much in reducing effluent water concentration. On the contrary, it can reduce the removal rate of the system.
