印染、造纸、食品、农药、煤气等行业及城市生活污水的处理，在活性污泥法处理工 艺中被普遍采用，通过对污水和污泥进行混合及充氧，活跃和繁殖好氧菌，对污水进 Self-priming submersible aerator is a high-efficiency and novel underwater aerator equipment. It is mainly used for the treatment of domestic sewage in the petroleum, chemical, tanning, printing and dyeing, papermaking, food, pesticide, and gas industries. It is widely used in the sludge treatment process . By mixing and aerating the sewage and sludge, aerobic bacteria are activated and multiplied, and the sewage is introduced into the sewage.
Biochemical effect, so as to achieve rapid and efficient purification of sewage. This machine occupies a small area, no odor overflow, no water splash, no noise interference, especially suitable for environmental requirements.
High-level places (such as hotels, restaurants and high-end living quarters, etc.) sewage purification treatment, and can be buried underground for use.
Structure and characteristics
1. This machine is composed of submersible motor, impeller, suction cover, diversion tank seat, filter seat and so on. There are also accessories, muffler, lifting chain, electrical control cabinet (suction pipe and air valve are standard parts, user-made).
2. The machine is simple in structure, light in weight, and does not require a blower. The whole machine is immersed in water. The motor directly drives the impeller to rotate, sucks water and sucks air, and sprays ultra-fine air bubbles into the sewage through the gas-liquid impact effect to obtain the best. Oxygen dissolution efficiency.
3. Although the whole machine is running in water, the motor is safe and reliable because it is equipped with alarm protection devices such as water immersion, overload, and overheating.
4. The air valve of the suction pipe can adjust the air supply volume, and a silencer is installed at the air inlet to reduce the noise of the suction pipe.
5. Since the whole machine is immersed in water, it has no noise and no foam splash. The well can be capped to eliminate odor and have good heat insulation, especially in cold areas. In addition, the sewage in some industries generates a large amount of foam after being stirred, so that surface exposure treatment cannot be adopted, and the use of this machine can make up for its shortcomings.
6. The whole machine adopts acid-proof and alkali-resistant asphalt paint for anti-corrosion, which can meet the requirements of corrosive environment.
