Biological treatment process and main features of Wastewater Air Diffuser

- Jun 09, 2018 -

Wastewater Air Diffuser is to a certain extent an efficient sewage treatment aerator, which effectively includes a base, a primary ejector, a secondary ejector, a tertiary ejector, and A four-stage water ejector, in which the water ejectors at all levels are detachably mounted on the base, the ejector includes a throat pipe, and the throat pipes in the ejectors at all levels are horizontally connected by welding.

In the first-stage water injector of the Wastewater Air Diffuser, an inlet is provided, an inlet is provided in the second stage injector, and a nozzle is provided at the unconnected end of the four-stage emitter. To a certain extent, the new type of highly efficient sewage treatment aerator is provided. The strong flow of water and air are mixed and sprayed to make the mixing even and complete. The bubbles produced are numerous and exquisite, and the dissolved oxygen efficiency is high. It can be carried out under high volume load conditions. The operation has higher dissolution efficiency than the aeration tube method, stable operation, uniform DO distribution in the aeration tank, higher purification efficiency, and lower operating cost.

Wastewater Air Diffuser is a necessary equipment for aeration and oxygenation of water supply and drainage to a certain extent. In operation, it can be effectively divided into surface aerator and underwater aerator according to its use method. Underwater aeration There are mainly microporous aerators and jet aerators. In the sewage treatment process, the biological treatment method can be divided into aerobic and anaerobic methods according to the aerobic conditions of the participating microorganisms.

In the process of biological treatment, the Wastewater Air Diffuser is generally effective in using an aerator to supplement the air in the treatment tank, so that the oxygen content in the treatment tank can be increased to a certain extent. Makes the microorganisms more fully act on the sewage. In the aeration tank of the sewage treatment biochemical system, the oxygenation efficiency is highly correlated with the growth of aerobic microorganisms. The amount of dissolved oxygen supply depends on the number of aerobic microorganisms, biological characteristics, Concentration, etc. to decide. Only in this way can a good degradation of organic matter be achieved.

Main features of Wastewater Air Diffuser


1. Oxygen utilization rate: During the operation process, each aerator has about 50,000 micropores of 1-3mm, and the aeration expands along the radial direction of the imported aeration tube, resulting in a large number of uniform and fine particles. Uniform bubbles greatly increase the gas-liquid contact area, and the oxygen utilization rate is as high as 40% or more.

2. High oxygenation efficiency: The film sleeve is small in thickness, high in elasticity and low in pressure loss. In the process of operation, the number of micro helium L on the film sleeve is large and dense, and the theoretical oxygenation power efficiency is as high as 9.0 or more. Shallow aeration effect (submerged depth 0.2m).

3. The Wastewater Air Diffuser has advantages of low investment, low energy consumption, low operating cost, and high cost performance, and is used in operation due to its high oxygen utilization rate and high oxygenation efficiency of ventilation of the product. Compared to mechanical aeration equipment. Save investment by up to 40%, reduce energy consumption and operating costs by more than 50%; Compared with disc-type variable microporous aerator, save investment by up to 30% and reduce energy consumption and operating costs by more than 20%. Significantly reduce project investment, effectively save operating costs and improve performance to price ratio.
