摘要
小区中水站长期运营过程中,进水水质普遍存在氨氮、总氮偏高的工况,对原因的分析可为中水站制定相应对策提供参考。文章选择中水站污水收集范围内的21个小区生活污水开展调研、检测,对中水站进行水质监测和数据分析。结果表明:居民的节约用水习惯、洗涤剂的大量使用以及粪尿量的相对集中是中水站进水高氨氮的主要原因;在此条件下,中水站有很强的抗冲击负荷能力,氨氮、化学需氧量、总氮和总磷的去除率分别达到了99.8%、92.5%、91.3%和92.0%;食物链反应器工艺符合未来“新概念污水厂”的理念,对实现污水处理行业走向高效节约的目标具有重要意义。
During the long-term operation of the community water station,the influent water quality is generally high in ammonia nitrogen(NH_(4)-N)and total nitrogen(TN).The investigation on the causes can provide a reference for the development of corresponding countermeasures for the water station.Water quality monitoring and data analysis were carried out in 21 residential areas within the scope of sewage collection in reclaimed water station.The results show that residents'habit of saving water,the extensive use of detergent and the relative concentration of feces and urine are the main reasons for the high ammonia nitrogen in the influent of the reclaimed water station.Under the condition of high influent ammonia nitrogen,the reclaimed water station has a strong impact load resistance,and the removal rates of NH_(4)-N,chemical oxygen demand(COD),TN and total phosphorus(TP)reach 99.8%,92.5%,91.3%and 92.0%,respectively.The food chain reactor process is in line with the concept of'new concept sewage treatment plant'in the future,which is of great significance to realize the goal of efficient and economical sewage treatment industry.
