  SODP Sulfur autotrophic nitrogen removal process system
 
 
Component     Invention patent No.: 201610490033.8

* Thiobacillus autotrophicus
* QCL-SODP Autotrophic Denitrification Biological Carrier
* SODP Autotrophic Denitrification Reactor
Patented product QCL-SODP sulfur autotrophic denitrification biological carrier, the carrier uses a special modification process to remove the necessary nutrient source of Thiobacillus denitrificans, and can load Thiobacillus denitrificans in high density after solidification. Thiobacillus denitrificans is an obligate autotrophic denitrifying bacteria that obtains energy in the process of oxidizing sulfide and has the property of removing nitrate nitrogen, thereby degrading total nitrogen (TN) in polluted water.
  Compared with the heterotrophic denitrification process, the SODP autotrophic denitrification process system does not need to add any organic carbon source when degrading nitrate nitrogen in total nitrogen, ensuring that the total nitrogen (TN) discharge of water quality meets the standard, which is the best at home and abroad Process system to remove total nitrogen (TN)!

Application note

1. Scope of application
(1) Degradation of TN in urban domestic sewage
(2) Degradation of TN in lakes, reservoirs and rivers
(3) Degradation of total nitrogen in various industrial wastewaters, including: Printing,Electroplating, Papermaking, Printing and dyeing, Food, Surface treatment, etc.
2. Design reference
(1) SODP Autotrophic Denitrification Reactor:Adopt the lower inlet and upper outlet to reach the reactor with internal circulation.It is designed according to the best response effect and can be customized.
(2) QCL-SODP Biological carrier addition:Based on the maximum influent concentration, no addition in the first two years.Starting from the third year, approximately 2%~3% will be added each year based on actual loss.                                                        

Features
No need to add organic carbon source
Sewage pH value remains neutral
No need to expand or modify existing sewage treatment equipment
The amount of sludge produced is very small, or even negligible
The carrier has a large specific surface area and can cultivate a high concentration of Thiobacillus denitrificans
Connect to existing sewage treatment equipment without long-term shutdown and short time-consuming
