Dissolved air flotation machine adopts advanced biological treatment process and is currently the most efficient sewage treatment equipment. It is widely used in various sewage treatment sites. The following points should be paid attention to when using it.
1. It is necessary to fully study and discuss the water quality of the water to be treated, and analyze the rationality and applicability of the air flotation process;
2. Under the conditions, the necessary air flotation small experiments or model experiments should be carried out for the wastewater to be treated. According to the experimental results, the appropriate dissolved air pressure and reflux ratio should be selected.
3. According to the type of coagulant, dosage, flocculation time, degree of response, etc. selected in the experiment;
4. To confirm the pool type of the air flotation tank, it should be considered inductively according to the requirements for water quality, the connection between the clean water process and the pre- and post-treatment structures, the coordination of the surrounding terrain and structures, the difficulty of construction and the cost of construction;
5. It is necessary for the touch chamber to provide good touch conditions for air bubbles and flocs, and the width should consider the requirements of installation and maintenance.
