Description
Technical Field
The invention belongs to the field of sewage treatment, relates to an aeration technology, and particularly relates to a control device and a control method suitable for a river and lake jet aerator.
Background
Jet aerator as an aeration and oxygenation method is applied to wastewater treatment from the 40 th age of 20 th century, and has a history of more than 60 years. When the jet aerator works, water is discharged from the water pump and flows into a nozzle of the jet aerator, the liquid is sprayed out from the nozzle at a very high speed along with the reduction of the diameter of the nozzle, the liquid flowing at a high speed passes through the air suction chamber and enters the mixing pipe (throat pipe), local vacuum is formed in the mixing pipe (throat pipe) and the air suction chamber, and a large amount of small bubbles and water are divided into a mixture under the action of water pressure after a large amount of air sucked through the air inlet enters the mixing pipe (throat pipe). The gas-liquid mixture is discharged outwards through the diffusion pipe, the speed of the gas-liquid mixture is reduced, the pressure is enhanced to form a powerful jet flow, and the wastewater is stirred and oxygenated. After being disturbed by cutting and jetting for many times, the bubbles are changed into countless fine bubbles, the surface area of the fine bubbles is very large, and oxygen in the air is more easily and quickly dissolved in water. Because the bubbles have small diameter and slow rising speed, the time that oxygen in the atmosphere is dissolved in water is prolonged, the wastewater and the oxygen are promoted to be fully mixed and contacted, reducing substances in the wastewater are oxidized, most of reducing bacteria and other anaerobic bacteria are killed, and the aim of treating the wastewater is fulfilled.
However, the structural parameters of the conventional jet aerator in the current market are generally designed according to the application of large-scale sewage treatment facilities, and have larger air inlets and larger air suction amount, while the general large-scale sewage aeration tank has higher submerged water depth, generally more than 5m to 7m, and the main reason is that the water depth of the aeration tank is increased, and when the effective power is similar, the mixed liquid bubbles sprayed by the jet aerator can obtain larger space utilization rate. The oxygen transfer rate can be improved, and the oxygen absorption is in a certain proportion to the submerged depth. Meanwhile, under the same air suction structure parameters, the jet aerator has large air suction amount under the working condition of small submerged water depth, and the air suction amount becomes small along with deepening of the working condition water depth, so that a larger air suction amount structure is generally designed. Therefore, the conventional jet aerator in the market is directly applied to urban river and lake water body treatment, and ideal working conditions are difficult to obtain. The water depth of the urban river and lake water is generally shallow, and the water depth is greatly influenced by the rising tide and the falling tide, and the water quality of the urban river and lake water also greatly changes.
