| 摘 要： | 在分点进水高效除磷脱氮工艺(ECOSUNIDE)中,以统一动力学为理论基础,对动力学方程进行了分析,并对分点进水高效除磷脱氮工艺进行了工程性试验.研究表明,分点进水高效除磷脱氮系统比另一组未改造的A2/O系统可多处理水量4 500 m3/d,具有明显的水量优势。在低温、低碳源条件下,分点进水高效除磷脱氮系统出水BOD,COD和氨氮质量浓度分别稳定在6,25和1.9 mg/L左右,满足国家城镇污水处理厂污染物排放标准(GB 18918—2002)一级A出水标准,其他指标稳定达到一级B出水标准。通过对分点进水高效除磷脱氮与A2/O系统内的活性污泥进行镜检分析比较,发现分点进水高效除磷脱氮系统内的活性污泥性状较好,生物相更丰富,污泥菌胶团颜色较深,较紧密,絮体边缘较清晰,丝状菌明显.

| Abstract: | Based on the Ecological Superior Nitrification Denitrification(ECOSUNIDE) technique and unified dynamics,the dynamic equation and theory were analyzed,and the engineering experiments on ECOSUNIDE process were conducted.The results show that the treatment capacity of ECOSUNIDE system is 4 500 m3/d more than that of A2/O system in the same conditions.Effluent BOD,COD and NH3-Nare about 6,25 and 1.9 mg/L respectively at low temperature and carbon source.These indexes meet with the Class I-A criteria specified ... |
