Abstract

The invention discloses a reactor of integrative combination technique for treating city sewage.The reactor comprises an anaerobic zone (2), a hypoxia zone (5), an aerobic zone (7) and a precipitate zone (11); one of sludge return tube (13) and another sludge return tube (14) which are provided with valves are connected with the anaerobic zone (2) and the hypoxia zone (5) from the precipitate zone (11) respectively; one of mixture return pipe (16) and another mixture return pipe (17) which are provided with valves are connected to front of the hypoxia zone (5) and the anaerobic zone (2) from end of the aerobic zone (7) and end of the hypoxia zone (5) respectively.The invention runs two sewage treatment techniques alternatively in the integrative reactor, by arranging an anaerobic pool, a hypoxia pool and an aerobic pool in the integrative reactor, nitrogen and phosphorus removal can be realized efficiently and economically.And under requirements of different conditions, the two techniques are alternatively run and technology resource is integrated, which can realize high-efficient and economical life sewage treatment function.

Description

technical field [0001] The invention relates to an integrated reactor, in particular to a kind of sewage treatment process by alternately operating two kinds of sewage in the integrated reactor: A 2 / O process and UCT process, so as to efficiently and economically improve the urban sewage integrated combined process treatment reactor for the denitrification and phosphorus removal treatment effect of the integrated reactor on urban domestic sewage. Background technique [0002] A 2 The / O (Anaerobic-Anoxic-Oxic) process is based on the original biological phosphorus removal A / O (Anaerobic-Oxic) process, embedded in an anoxic pool. Sewage undergoes nitrification reaction in the aerobic tank, the mixed liquid in the aerobic tank returns to the anoxic tank for denitrification and denitrification, and the phosphorus-containing sludge in the sedimentation tank returns to the anaerobic tank together with the raw water for anaerobic phosphorus release. Then go to the aerobic pool ...
