What are the precautions for microporous aerators?

Functions of aeration equipment: 1Increases dissolved oxygen in water and provides oxygen to water treatment microorganisms.

2.Increases dissolved oxygen in water and provides oxidant oxygen for deironing. 3.

Increase the air content in the water, and during the decompression process, air bubbles are formed on the surface of oil impurities, etc., which float them up for separation and removal. 4.Pretreatment, increase the oxygen content in the water, prevent the water from being rancid, form a certain stirring effect on the water, and prevent the deposition of substances in the water.

1. The air inlet of the fan must have an air filtration device, and it is best to use electrostatic precipitator and other methods to minimize the content of suspended particles in the air.

2. To prevent oil mist from entering the air supply system and avoid using air sources with oil mist, it is best to use centrifugal fans for fans.

3. When the gas pipeline is made of steel pipe, the inner wall should be strictly anti-corrosion, and the gas distribution pipe and pipe fittings in the aeration tank should be made of high-strength plastic pipes such as ABS or UPVC, and the connection between the steel pipe and the plastic pipe should be provided with expansion joints.

4. The microporous aerator is generally distributed at the bottom of the pool, the distance from the pool wall should be greater than 200mm, the spacing between the distribution pipes is 300 750mm, and the length and width ratio of the aeration tank using the microporous aerator is (8 16): 1.

5. The height difference of the surface of the microporous aerator in the whole pool shall not exceed 5iilln, and clean water shall be poured into it for verification after installation. When the gas is stopped during operation, it should not be more than 4 hours, otherwise the sewage in the tank should be emptied, filled with clean water with a depth of 1 m or the water from the secondary sedimentation tank, and continuous aeration with a small air volume.

Aerator series: disc diaphragm aerator, microporous aerator, aeration head, rubber tube aerator, diffuser aerator, dynamic aerator, spin-mixed nylon aerator, aeration hose, double spiral aerator, etc.

The pro-microporous aerator is a type of aerator. These are the microporous aerators.

The selection of aeration equipment not only affects the effect of sewage biochemical treatment, but also affects the land occupation, investment and operation costs of sewage treatment plants. Microporous aerators mainly include: hanging chain aerator, diaphragm microporous aerator, rotary cut aerator, tubular aerator, disc aerator, microporous ceramic aerator, hose aerator, etc.

1. The suspension chain aerator is a new type of energy-saving aeration equipment in petrochemical, textile, oil refining, coking, papermaking, printing and dyeing, slaughtering, brewing, pharmaceutical, tanning and other industrial wastewater and urban domestic sewage and forest water biochemical treatment projects.

2. When the efficiency of the running aerator is low or the blockage is frequent and the maintenance is not done, the suspension chain aerator can be used to transform it to improve the aeration capacity and stirring effect.

3. It is used for pre-aeration of sewage regulating tank to prevent the deposition of large particles of sediment and remove part of the organic matter.

Petrochemical, textile, oil refining, coking, papermaking, printing and dyeing, slaughtering, brewing, pharmaceutical, tanning and other industrial wastewater.

The product is suitable for new construction and expansion of municipal sewage and large-scale factories and the renovation of old aeration tanks, and the aeration tanks can be operated intermittently.
