Abstract

The invention discloses a sewage treatment plant standard-improving transformation system. The system comprises an in-situ transformation DAT-IAT biochemical pond, an additionally added intermediate water pond, a pipeline mixer, a grid flocculation pond, an oblique tube sedimentation pond, a D-type filtering pond and a clean water pond; a front segment of a DAT pond is arranged as an anoxic zone,a rear segment of the DAT pond is arranged as an aerobic zone, and submersible stirrers are diagonally arranged at the bottom of the anoxic zone; the aerobic zone is internally provided with fillers;the bottom of an IAT pond is provided with a mixed liquid reflux pump which is connected with a tee pipe, and the tee pipe is connected with a reflux main pipe, a remaining sludge discharge pipe and areflux bypass pipe; the standard-improving transformation system further includes a sludge pond, and the sludge pond is communicated with the intermediate water pond. The invention also provides a method for treating sewage by using the standard-improving transformation system. The construction difficulty is low, the period is short, the effect acts fast, the transformation cost is low, and allindexes of treated effluent water after transformation can stably reach first-level A standards of pollutant discharge standards of urban sewage treatment plants.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a sewage treatment plant upgrading system and a sewage treatment method. Background technique [0002] Since the promulgation and implementation of "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002) in 2002, the number of urban sewage plants in my country has continued to increase, but the requirements for discharge standards at that time were relatively low. Tier 1 or Tier 1 B emission standards. [0003] In the face of my country's still severe water environment situation, improving water pollution and improving the quality of living life has become an important task for building a beautiful China and promoting green development. Relevant governance policies have been implemented successively to ensure the advancement of pollution prevention and control work. The "Water Pollution Prevention and Control Action Plan" ("Water Ten ...
