摘要:

针对焦化废水生化处理过程中好氧阶段的泡沫问题,通过控制进水水质、稳定好氧池温度在30~32℃、保证溶解氧在3~4mg/L、适当增大污泥的回流比例等措施能够有效控制泡沫的产生,改善出水水质。

Abstract:

The formation of foam during aerobic period in the biological treatment process of coking wastewater can be controlled by improving the quality of inlet water,stabilization of temperature in aerobic tank at 30~32℃,keeping the concentration of dissolved oxygen between 3mg/L and 4mg/L,and increasing properly the proportion of returned sludge.
