Food wastewater treatment (removal of animal and vegetable oils)
Created on 05.14
Biological efficiency enhancement project for wastewater treatment of a certain oil processing company
- Project Overview
(1) Company Profile: A Fortune 500 foreign-funded enterprise
(2) Wastewater type: Food wastewater treatment (excluding animal and vegetable oils)
(3) Wastewater treatment capacity: 220m ³ /d
(4) Treatment process: Two-stage oil separation + regulating tank + air flotation machine + aeration tank + secondary sedimentation tank
(5) On-site issues: The wastewater has a high oil content and concentration, and there is no anaerobic process. Frequent high-density shocks are caused to the aerobic tank, resulting in sludge bulking.
- Governance measures
The addition of the Qinggang ® series of highly efficient strains features dual high-efficiency characteristics: short acclimation time, strong pollutant removal ability, and the ability to quickly restore biochemical flora.
Strain name | Specification | Annual consumption (kg/year) | Note |
Qinggang® Oil Removing Bacteria | ≥ 20 billion cfu/g | 720kg | Regular procurement |
Qinggang® COD Removal Bacteria (Aerobic) | ≥ 200 billion cfu/g | 720kg |
- Governance effect
Adding our company's highly efficient oil-removing bacteria and aerobic COD removal bacteria to enhance the cultivation of the biochemical system can effectively reduce the COD removal load of the aerobic tank and minimize the impact of high COD load.
