Water pollution is an environmental problem all over the world, whether it is in developing or developed countries, this problem has attracted more and more attention. Due to the diversity of industrial wastewater components, a treatment system composed of several methods is often required to achieve the required discharge standards. It can be divided into four types: physical method, chemical method, physical chemical method and biological method. Biological method is a method that uses the metabolism of microorganisms in wastewater to decompose degradable organic matter in water. Because of its large processing capacity, low investment, and economical reliability, it is the most common water treatment method in the world today.
In the aeration tank of the sewage treatment biochemical system, the oxygenation efficiency is positively correlated with the growth of aerobic microorganisms. The supply of dissolved oxygen should be comprehensively considered according to the number of aerobic microorganisms, physiological characteristics, substrate properties and concentration. In this way, activated sludge can be in a state of degrading organic matter well. According to experiments, it is advisable to maintain the dissolved oxygen in the aeration tank at 3 to 4 mg/L. If the oxygen supply is insufficient, the performance of activated sludge will be poor, resulting in a decrease in wastewater treatment effect. In order to ensure sufficient oxygen supply, it must be done by a device, such as an aerator.
Tubular aerators are mainly used for oxygenation of urban sewage and organic industrial wastewater treatment systems. Tubular aerators have simple structure, high oxygen utilization, reliable performance, stomata are not easy to be blocked, sewage does not backflow, and are subjected to circumferential forces. The characteristics of uniformity, long life, convenient installation and maintenance, and low system price. It has good chemical stability, does not contain plasticizers, can maintain elasticity for a long time, is acid and alkali resistant, does not harden, does not embrittle, and does not age. The bubble diameter of the product is small, which can not only maintain a high oxygen conversion rate, but also achieve the effect of mixing and stirring. With self-closing pore structure, the micropores are not blocked. Easy to install and disassemble. Reduce energy consumption.
