The main function of coagulation is to promote the sedimentation efficiency so as to prolong the washing cycle of rapid sand filter and in the meantime the turbidity of raw water is greatly reduced. Sizes of suspended particles which form turbidity cover a wide range and their properties are diverse too. The treatment efficiencies of processes about the removal of different suspended particles are different. In the study of treatment processes of turbidity removal of raw water, it may be better to classify...

The main function of coagulation is to promote the sedimentation efficiency so as to prolong the washing cycle of rapid sand filter and in the meantime the turbidity of raw water is greatly reduced. Sizes of suspended particles which form turbidity cover a wide range and their properties are diverse too. The treatment efficiencies of processes about the removal of different suspended particles are different. In the study of treatment processes of turbidity removal of raw water, it may be better to classify the turbidity into different classes. It is suggested that the turbidity of raw water may be classified into settleable turbidity, coagulatod-settleable turbidity, unfilterable turbidity and coagulable turbidity. And a draft of their determination methods is proposed for further studies.

混凝的主要作用是提高沉淀效率,借以延长滤池洗砂周期;同时,在降低浑浊度上起了作用.致浊粒子的粗细范围很广,且性质不同.所用处理方法去除不同致浊粒子的效果不同,浑浊度宜分类测定.建议分为自混浊度、混凝浊度、可滤浊度、聚沉浊度,并提出了测定方法草案,供进一步研究.

Experimental research on pretreatment of polluted raw water with higher turbidity and higher ammonia-N concentration by biological contact oxidation process (BCOP) with elastic packing was conducted and compared with conventional water treatment process. Experimental results showed that removal rates of ammonia-N, COD Mn , and UV 254 were 60%~80%, 0.5%~25%, and 1%~15% respectively at raw water turbidity of 50~200 NTU, ammonia-N concentration of 1~10 mg/L and temperature of 18~30 ℃. During the...

Experimental research on pretreatment of polluted raw water with higher turbidity and higher ammonia-N concentration by biological contact oxidation process (BCOP) with elastic packing was conducted and compared with conventional water treatment process. Experimental results showed that removal rates of ammonia-N, COD Mn , and UV 254 were 60%~80%, 0.5%~25%, and 1%~15% respectively at raw water turbidity of 50~200 NTU, ammonia-N concentration of 1~10 mg/L and temperature of 18~30 ℃. During the test, higher turbidity (from 200 NTU to 800 NTU) of raw water had no significant effect on removal efficiency of ammonia-N and COD Mn . Nitrite removal rate was 20%~50%, but nitrite accumulation took place when ammonia-N concentration was rather high. With the BCOP, pollutants removal effects of subsequent sedimentation tank and rapid sand filter could be improved.

采用生物接触氧化技术预处理微污染原水 ,并和水厂常规处理工艺进行了对比。中试结果表明 ,原水浊度为 50~ 2 0 0NTU、氨氮浓度为 1~ 10mg/L、水温为 18~ 30℃时 ,生化池对氨氮的去除率为 6 0 %~ 80 % ,CODMn去除率为 0 .5%~ 2 5% ,UV2 54 的去除率为 1%~ 15% ;正常运行时 ,较高浊度 (2 0 0~ 80 0NTU)的冲击不会明显影响生化池对氨氮和CODMn的去除 ;生化池的亚硝酸盐氮去除率为 2 0 %~ 50 % ,在原水氨氮浓度较高时亚硝酸盐氮积累增多 ;增加生物接触氧化预处理工艺 ,显著提高了后续混凝沉淀池和砂滤池的除污染效果
