摘要:利用 IC 厌氧反应器处理废纸造纸废水,经过两个月的时间通过接种颗粒污泥、投加
营养盐、控制 ph 和进水等完成 IC 厌氧反应器的启动。通过进一步的提升负荷并连续运行一
年半后,IC 反应器的运行效果稳定,在进水 COD 浓度为 4000mg/L 左右的正常工况下,出
水 CODcr 浓度维持在 950mg/L 左右,有机负荷为 480kgCOD/d,CODcr 平均去除率稳定在
76%左右,出水 VFA 浓度稳定在 2~4mmol/L,出水的 pH 值稳定在 ~。

Abstract: In this paper it was reseached that the IC reactor was used to treat OCC wastewater,
more than two months was used to inoculating granular sludge, dosing nutrients, controlling ph
and the influent and then the IC reactor was essfully started up. Through the measure of
enhance the load and make it operate continuous for a year and a half, it was founded that the IC
reactor was operating stability, during the normal operating conditions, the concentration of
influent CODcr was 4000mg/L, the concentration of effluent CODcr was maintained at 950mg/L,
anic load was 480kgCOD/d, the removal rate of CODcr was 76%, the concentration of
effluent VFA was stabilized at 2~4mmol/L and the effluent pH was stabilized at ~.
