SEAFOOD WASTEWATER TREATMENT
1. Pollution characteristics and parameter
- Seafood wastewater has a stench and fishy odor due to the decomposition of the residue of marine organisms that heavily and directly affects the human living environment.
- The main component of seafood wastewater is toxic organic substances that are difficult to decompose, mostly bones, caudal fin, internal organs, etc of marine organisms. Due to the difficulty of decomposition, seafood wastewater is considered difficult to handle and very toxic.
2. Wastewater treatment process
- Wastewater from the receiving source will lead to the garbage filter to remove large trash such as bones, fish fins, etc
- Next, wastewater is led by the system into the regulating tank
- Wastewater through Aerotank microbiological treatment tank: Wastewater continues to be aerated to increase dissolved oxygen content in water
- Then, wastewater will flow through the sedimentation tank: The clear water will continue to flow through the disinfection tank before discharging into the environment a large amount of bio-sludge will be pumped back to the biological tank
3. Outstanding advantages
- Type A wastewater after treatment is easy to operate, small construction area, no odor, low cost.
