AHBS® process is an air source powered biological doubling sewage treatment system independently developed by Shuijingyuan Environmental Technology Co., LTD. This process has no underwater mechanical power equipment for secondary biological treatment and advanced treatment, and the number of microorganisms per unit pool capacity, oxygen efficiency and pool capacity utilization rate are tripled.The effluent water quality can meet the Class III and IV standards of surface water quality standards.

The process occupies a small area, low investment, low operating cost, simple maintenance, especially suitable for wastewater plant in situ upgrading and full buried garden wastewater plant. It has been successfully applied in China (Beijing, Hebei, Ningxia, Henan, Zhejiang, Anhui, Shandong, Hainan etc.), Malaysia, Pakistan for more than 10 years.

   New Aeration

ü High oxygen transfer efficiency

ü Maintenance under the upremise of not stopping production, saving time and effort

ü The service life is more than 15 years

ü Single tube and single control

ü Suitable for a variety of pool types, wide application range

   New Sludge return

ü Sludge reflux is carried out with air source as power，

ü All power equipment such as pusher, reflux pump and scraper suction machine are banned

ü Mixed liquid high proportion gas stripping cycle。

   New Sedimentation

ü High solid flux, high surface load and integrated structure design

ü Aeration and precipitation combination, intensive integrated structure design;

ü No power equipment mud scraper, reflux pump, etc

   New Aeration control

ü The aeration of the biochemical system is controlled by PLC, and each functional area can be freely converted, which can give full play to the role of time and space nitrogen removal, minimize the amount of additional carbon sources, and thus reduce the operating cost

   Efficient Microorganism

ü The number of microorganisms in the biological treatment tank is doubled, the flora is diversified, and the degradation is efficient, which is conducive to effectively degrading the organic pollutants that are difficult to degrade in water, and improve the removal efficiency and treatment capacity of microorganisms.

   Efficient sedimentation tank

ü The new efficient coagulation sedimentation tank uses air source as the power, and bans the mixing mixer, flocculation mixer, mud scraper and sludge pump of the traditional coagulation sedimentation tank, saving investment and light maintenance

New Denitrifying biofilter

ü The use of composite filter material, at the same time with filtration, denitrification functions

ü TN removed 5-10mg/L

ü The effluent SS can be stabilized within 5mg/L

ü Flushing volume  ≤ 5%

AHBS is very suitable for single-layer (only one negative layer) fully buried garden wastewater treatment plants
