生物过滤-氧化催化-高速过滤技术处理含垃圾滤液的城市污水研究

分析了垃圾渗滤液的特点、处理方法的异同及难点,并提出了相关的应对措施。在此基础上结合实际,对含有垃圾渗滤液的城市污水研发了包括生物处理和深度处理相结合的技术,采用生物过滤-氧化催化-高速过滤技术3种高效深度水处理工艺,较好地实现了城市污水的处理,达到国家一级排放标准:COD≤60 mg/L,BOD≤20 mg/L,SS≤20 mg/L,可实现再生回用。

Study on Disposals by Biofiltration-Oxidation Catalysis-High Speed Filtration for City Sewage Containing Rubbish Percolate

The disposals of rubbish percolate are analyzed according to its characteristics, different treatments and difficulties, as well as providing some measures. In this paper, a new technology to dispose city sewage is developed by integrating biochemistry and depth treatment,including biofihra- tion, oxidation catalysis and high-speed filtration processes to realize disposal of city sewage success- fully by reaching state primary effluent standard, COD ≤60 mg/L, BOD ≤20 mg/L, SS ≤20 mg./L. Rejuvenated water is available by this technology.
