What are the commonly used Jiangmen sewage treatment agents
Sewage discharge leads to serious pollution of water resources and living environment. In order to prevent the deterioration of this phenomenon, the water treatment industry has developed a number of large-scale water treatment equipment, which are applied in the treatment of production and domestic sewage. There are a lot of refractory substances in the sewage discharged by many enterprises, which can not be removed by a single water treatment equipment. Therefore, it is necessary to add sewage treatment agents reasonably according to the particularity of sewage quality to make the treated sewage meet the national discharge standards.
1. Flocculant: it can separate the stubborn substances from the liquid, and is often used in the process of primary sedimentation tank, secondary sedimentation tank, tertiary treatment or in-depth treatment, mainly using polyacrylamide.
2. Coagulant aid: auxiliary flocculant plays a role to strengthen coagulation effect.
3. Conditioner: conditioning the excess sludge before dewatering.
4. Demulsifier: mainly used in pretreatment of oily wastewater.
5. Defoamer: it is mainly used to eliminate a large number of bubbles produced in the process of aeration or mixing.
6. PH regulator: used to adjust the acidity and alkalinity of sewage.
7. Redox agent: mainly used in the treatment of wastewater containing oxidizing or reducing substances.
8. Disinfectant: used in the disinfection treatment of wastewater before discharge or reuse.
