Abstract

The invention relates to a design calculation method of enlarging volume of the sewage plant. A design calculation method of using A / O type bio-aeration filter to enlarge the volume of said sewage plant, including one-level effluent-handling prime settling pool (2), second-level effluent-handling second settling pool, whose main feature is: set water-intake balancing tank (4) on water-outlet end of said second settling pool (1), connect the tertiary sewage treatment A / O type bio-aeration filter (3) to water-intake balancing tank (4). The invention requires the quality of outlet-water completely after enlarging the volume on the base of present outlet-water quantity of second settling tank and the quality of second settling tank, prime settling tank, calculates some main design parameters such as: outlet-water quantity of said introduced prime settling tank, outlet-water circulating mass, volume of anoxybiotic section, volume of aerobic section, etc. The invention is characterized by: precise calculating method, reliable parameters, A / O type bio-aeration filer applied to the design calculation of enlarging volume of tertiary treatment of present urban sewage plant.

Description

Technical field:

[0001] The invention mainly relates to a design and calculation method for capacity expansion of a sewage treatment plant. Background technique:

[0002] The meaning of urban sewage treatment plant expansion means that the treatment water volume of the existing urban sewage treatment plant has reached the original design water volume, but the water inflow is still increasing, the capacity of the existing treatment equipment can no longer meet the requirements, and technical transformation and expansion are needed ; or due to various reasons, the effluent quality of the existing urban sewage treatment plants does not meet the requirements of the discharge standard, and it is necessary to carry out technical transformation on the existing treatment process or add some treatment equipment to improve the effluent water quality; or both.

[0003] With the development of society, the urban population and industrial production, the corresponding amount of urban sew...
