Assembled sequencing batch fluidized bed sewage treatment equipment and process

Abstract

The invention discloses assembled sequencing batch fluidized bed sewage treatment equipment. The equipment comprises a shell and is characterized in that the shell is an assembled tank body; an umbrella-shaped inner shell is arranged inside the shell; the interior of the umbrella-shaped inner shell is a reaction zone; a settling zone is arranged between the shell and the umbrella-shaped inner shell; suspended fillers suspend in the reaction zone; an aeration device is arranged at the bottom of the reaction zone; a filler isolating net is arranged between the reaction zone and the settling zone; the reaction zone is connected with a water inlet pipe; a water outlet pipe is arranged at the upper part of the shell; a water decanter is arranged in the settling zone; a water outlet of the water decanter is connected with the water outlet pipe. The invention also comprises a process for treating sewage by adopting the equipment. The sewage treatment equipment and the sewage treatment process have the advantages of short construction cycle, investment saving, low energy consumption, low operating cost, strong impact resistance load capacity, good treatment effect, strong nitrogen and phosphorus removal capacity, convenience in operation management, high degree of automation, no noise, flexible assembly and the like.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an assembled sequence batch fluidized bed sewage treatment equipment and process. Background technique [0002] With the rapid economic development and the continuous improvement of people's living standards, industrial and agricultural production, domestic water consumption and total sewage discharge continue to increase, especially in towns and rural areas, a large amount of sewage is produced every year, and due to scattered water sources, pipeline Due to the difficulty of laying, the low technical level and management level of employees, the sewage treatment rate in towns and rural areas is low, and sewage treatment is difficult. Therefore, it is necessary to adapt measures to local conditions and seek economical, efficient, energy-saving and easy-to-operate sewage treatment solutions. . [0003] Sequencing batch intermittent aeration activated sludge process has attracted ex...

AI Technical Summary

Problems solved by technology

Reinforced concrete pools have complex construction techniques, long periods, cumbersome structural design, and high cost, and are not suitable for small and medium-sized sewage treatment projects; while steel structure welded tanks are welded on site, the construction quality is difficult to guarantee, and the anti-corrosion performance is poor, the service life is short, The pool volume is small, which limits the application of bioreactors
