Phosphorus removal sewage treatment equipment dissolved air flotation machine
Dissolved air flotation machine is an effective sewage treatment equipment, which is mainly used to remove various pollutants from sewage, including phosphorus. Here are the specific steps on how a dissolved air flotation machine can effectively remove phosphorus from sewage:
, adsorption and adsorbate transfer:Dissolved air flotation machines separate phosphorus from sewage through the process of adsorption and adsorbate transfer. As the effluent passes through the equipment, particulate matter and organic matter are adsorbed on the bubbles, making it easier to remove phosphorus from the effluent.
, adsorption process: The adsorption materials (such as activated carbon, diatomaceous earth, etc.) in the dissolved air flotation machine can effectively adsorb phosphorus and other harmful substances in sewage.
, adsorbate transfer:The adsorbed effluent mixes with air to form tiny bubbles that bind to phosphorus and other contaminants in the sewage, making it easier to separate from the water.
, pressure change:Dissolved air flotation machines use pressure changes to attach particulate matter from sewage to air bubbles, a process known as floating. By adjusting the pressure inside the equipment, the speed and direction of the particles can be controlled, thereby improving the efficiency of phosphorus removal.
, Filtration & SeparationAfter a pressure change, the particles-attached bubbles pass through the filter and separator, separating the contaminants from the water, thus removing the phosphorus.
1. The mechanical structure of the dissolved air flotation machine
What are the main structures of the dissolved air flotation machine?In fact, this is also the advantage of air flotation machine, on the whole, the structure is simple, the efficiency is high, and it is a cost-effective equipment. Here's what it looks like:
1.High-pressure pump: The high-pressure pump is the basis of the entire dissolved air flotation machine, and its main role is to pressurize the air to the required pressure to provide power for the production of tiny bubbles.
2.Air storage tank: The air storage tank is an important part of the air flotation machine, and its main function is to protect the high-pressure pump from damage to the equipment due to pressure fluctuations. At the same time, the air tank can also be used for the initial mixing and dissolution of the air.
3.Gas supply line: The gas supply line is a pipeline system that connects the high-pressure pump and the flotation unit, which includes control valves and venting valves, etc., which are used to regulate and control the air flotation process.
4.Inclined plate sedimentation device: The inclined plate sedimentation device is located at the bottom of the dissolved air flotation machine and is used to remove suspended solids from flotation. The device has high sedimentation efficiency and good hydraulic properties, which can effectively improve the phosphorus removal effect.
Second, the application of dissolved air flotation machine in various industries
Dissolved air flotation machines are widely used in many industries, not only for phosphorus removal, but also for the following industries:
1.Industrial wastewater treatment: Dissolved air flotation machine can effectively remove harmful substances such as suspended solids and phosphorus in industrial wastewater, and improve the efficiency and quality of wastewater treatment.
2.Domestic sewage treatment: dissolved air flotation machine is also widely used in domestic sewage treatment, which can effectively remove suspended solids and organic matter in domestic sewage and improve the efficiency and quality of sewage treatment.
3.Food processing wastewater treatment: dissolved air flotation machine also has a good application effect in the treatment of food processing wastewater, which can effectively remove suspended solids and pollutants and ensure the safe discharge of food processing wastewater.
4.Textile printing and dyeing wastewater treatment: dissolved air flotation machine also plays an important role in the treatment of textile printing and dyeing wastewater, which can effectively remove suspended solids and pollutants and improve the efficiency and quality of wastewater treatment.
In general, as an efficient phosphorus removal sewage treatment equipment, dissolved air flotation machine has been widely used in many industries, and its working principle and mechanical structure are relatively mature and perfect. Through the rational use of dissolved air flotation machine, the effect and quality of sewage treatment can be effectively improved, and environmental safety and ecological health can be guaranteed.
