Description
技术领域 technical field
本实用新型属于曝气装置技术领域，具体涉及注气自吸双向可调式高效低耗射流曝气系统。 The utility model belongs to the technical field of aeration devices, in particular to an air-injection self-absorption bidirectional adjustable high-efficiency and low-consumption jet aeration system.
背景技术 Background technique
按照供气方式的不同，射流曝气器可分为压力供气和自吸供气两大类。 According to the different air supply methods, jet aerators can be divided into two categories: pressure air supply and self-priming air supply.
压力供气方式采用鼓风机供气，曝气效果较强，且空气量的控制比较方便。但是压力供气能耗较大，仅适合作为高浓度废水的曝气充氧系统，且普遍淹没在水中，安装与维修十分不方便。 The pressure air supply method adopts the blower to supply air, which has a strong aeration effect and is more convenient to control the air volume. However, pressure air supply consumes a lot of energy and is only suitable as an aeration and oxygenation system for high-concentration wastewater, and it is generally submerged in water, making installation and maintenance very inconvenient.
自吸供气利用负压作用将空气吸入曝气器内腔从而达到水汽混合的作用。优点是无需鼓风机，减少了投资和动力费用，缺点是曝气效果较差，仅适合作为低浓度废水的曝气充氧系统，且只能安装在水面以上，使得曝气器的成本较高。 Self-priming air supply uses negative pressure to suck air into the inner cavity of the aerator to achieve the effect of water vapor mixing. The advantage is that no blower is needed, which reduces investment and power costs. The disadvantage is that the aeration effect is poor, and it is only suitable as an aeration and oxygenation system for low-concentration wastewater, and can only be installed above the water surface, which makes the cost of the aerator higher.
射流曝气活性污泥法在印染废水预处理领域被广泛应用。但是当前市场上应用的单一射流曝气器在废水水质、水量变化幅度大的情况在，压力供气和自吸工艺两类射流曝气器在实际应用中均有各自的局限性，无法达到处理效果和处理成本的最佳平衡。 Jet aeration activated sludge method is widely used in the field of printing and dyeing wastewater pretreatment. However, the single jet aerators currently used in the market have their own limitations in practical application when the water quality and water volume of wastewater vary greatly. The best balance of effects and processing costs.
