Introduction to aerator manufacturers: How to choose environmentally friendly equipment aerators?
Aeration technology is a commonly used environmental protection technology in enterprise wastewater treatment. Aeration device is a necessary environmental protection equipment for water supply and drainage aeration and oxygenation. Aeration is a means of promoting the exchange of gas-liquid substances, with the aim of dissolving oxygen in water or expelling unnecessary gases and volatile substances from water into the air.
There are various types of environmental protection equipment aerators. Today we will introduce how to choose an aerator? According to the usage method, environmental protection equipment aerators can be divided into surface aerators and underwater aerators. Underwater aerators mainly include microporous aerators and jet aerators. Through continuous updates and development, its structure and performance are constantly evolving.
There are generally two types of aeration: one is blast aeration, and the other is mechanical aeration. Among them, aeration heads, aeration tubes, and suspended chain aerators are commonly used for air blowing aeration. They all have high oxygen utilization efficiency and power efficiency, with better energy-saving effects. The aeration tube not only provides uniform aeration, but also can only meet the requirements when the ventilation volume is high, resulting in low cost. The structure of the aeration head and aeration tube is simple, easy to install, and the engineering and equipment costs are low.
Hanging chain aerators and elevating aerators are easy to troubleshoot, maintain, and manage. When these two aerators malfunction, the water surface can be raised for maintenance. After other bottom aerators malfunction, they need to be removed. The drainage pool greatly increases investment. So how to distinguish the advantages of these two types of aerators? Although suspended chain aerators are also easy to troubleshoot, maintain, and manage, due to their swinging back and forth on the water surface, the aeration is relatively uneven, and the layout cannot be too dense. If it is dense, additional weights must be added. Just need to increase the aerator. Uniform aeration can achieve the same or even better effect as aeration pipes, but the cost is high.
In fact, the selection of aerators mainly considers the following factors:
1. The air diffusion device should have high oxygen utilization efficiency and power effect, and good energy-saving effect; 2. Not easy to block, easy to troubleshoot, and convenient for maintenance and management; 3. Simple structure, easy installation, low engineering cost, and low equipment cost itself; 4. In addition, the water quality of the sewage, regional conditions, and type of aeration tank should also be considered. Water depth. Ventilation, etc.
