摘要
城市生活污水污染负荷已超过工业废水污染负荷,处理工艺的优化就成为当今城市污水处理的重要课题。采用生物膜处理工艺对城市污水进行生物处理和化学除磷,通过为期一年的试验表明,考核的主要污染物指标达到GB18918-2002一级排放标准。
Pollution load of city sewage has already exceed the sewage of industry pollution load, so the disposal technology optimizing became an important problem of dealing with city sewage nowadays. Adopting biological membrane method to have biological treatment and chemical dephosphorizing on city sewage, through one year＇s experiment, it indicated the main pollutant reached GB19918-2002 grade I of control standard.
