Abstract
Based on batch experiment for optimization of dosages of water treatment agents, treatment efficiency of high-density sedimentation tank on raw water with high ammonia nitrogen concentration and high organic pollutants concentration were studied. The results show that: the turbidity of effluent of sedimentation tank and filtration tank can be stably below 0.8 NTU and 0.2 NTU separately. When powdered activated carbon is used, removal efficiency of sedimentation tank on CODMn, increases from 29.3 % to 36.9 %, and reaches 45.4 % totally with filtration tank. For ammonia nitrogen, removal efficiency of sedimentation tank reaches 69.8 % from S7.2 %, and 76.6 % totally with filtration tank. The usage of powdered activated carbon in high-density sedimentation tank improves the removal efficiency of turbidity, ammonia nitrogen and organic pollutants.关键词
