摘　　要：城市污水二级出水中含磷量较高,需进一步处理后才能达标排放。利用锅炉煤渣对城市污水二级出水进行处理,研究了pH值,锅炉煤渣加入量,反应时间、静置时间等因素对除磷效果的影响。结果表明,锅炉煤渣在8.0 g/L固液比的加入量、50 min的反应时间,60 min的静置时间下,处理城市污水二级出水可以达到污水综合排放一级标准。Urban sewage secondary effluent is rich in high phosphorus ,and hoped to treat further then drainaged standardly.In this study,boiler coal cinders was used to treat urban sewage secondary effluent,and it studied the effect of phosphorus removal on the effluent pH value,the adition amount of boiler coal cinders,the reaction time and the static placing time. The results showed that when the solid-liquid ratio of the adition amount of boiler coal cinders was 8.0 g/ L,the reaction time was 50 min,the static placing time was 60 min,urban sewage secondary effluent can meet the level lcritial of Integrated wastewater discharge standard.
