Integrated double-circulation oxidation ditch device for town sewage and treatment method

Abstract

The invention discloses an integrated double-circulation oxidation ditch device for town sewage and a treatment method. The integrated double-circulation oxidation ditch device comprises an anaerobic zone, an anoxic zone, an aerobic zone and a secondary sedimentation tank which are communicated in sequence, the anoxic zone comprises a first anoxic zone and a second anoxic zone; the aerobic zone comprises a first aerobic zone and a second aerobic zone, and a reflux pump is arranged between the anoxic zone and the aerobic zone. The anaerobic zone, the anoxic zone and the aerobic zone are internally provided with submersible stirrers, and the anoxic zone and the aerobic zone are respectively provided with a partition wall and a guide wall to form circulation in each zone; and the synchronous denitrification and phosphorus removal effect of nitrate nitrogen is realized in the anoxic zone, so that the purposes of stably removing organic pollutants COD and removing nitrogen and phosphorus are achieved, the COD removal effect is improved, and the nitrification and denitrification nitrogen removal and phosphorus removal efficiency is improved. The integrated structure of the device has the characteristics of simple structure operation and low cost, and the investment and operation cost can be further reduced.

AI Technical Summary

Benefits of technology

This new technology allows city water pollution control systems to efficiently treat harmful substances from various sources such as domestic wastes or industrial processes without adding more chemicals that are expensive compared with existing methods like biological ones. It also helps reduce costs by reducing the amount of time it takes to process these materials before they can be released into public waters.

Problems solved by technology

The technical problem addressed in this patented text relating to improving the use of recycled or greenhouse gas emissions from household sources like coal burning power generation systems due to their wide range of variation with time varying demands and limited availabilities. Current methods involve expensive treatments involving various types of equipment, leading to increased costs associated with landfill disposal operations. There is thus a strong motivator behind the challenge of finding ways to efficiently remove pollution elements without causing negative effects upon humans and wildlife worldwide.
