【 摘 要 】

Pesticide wastewater belongs to typical hardly-degradable ndustrial wastewater. Biochemical system pollutants removal efficiency was in low level because of high salt content and high biological toxicity. Adding biological synergist into biological system to improve the biological system activity, the pilot-scale study results show that: The CODCrand NH3-N removal rate has increased significantly after adding the biological synergist into the biological system. The CODCr average removal rate of experimental group was 91.2%, and the control group was 84.5%; The experimental group of NH3 - N removal rate up to 93.2% on average, higher than 51.4% of control group, and the nitrification efficiency was improved significantly. The specific oxygen uptake rate (SOUR) of the synergistic sludge was higher than that of the control group, indicating that the microbial metabolism rate was improved, the sludge structure of the experimental group was tight, and the metazoa appeared. The biological activity was better than that of the control group.
