Embodiment Construction
[0021] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0022] Such as figure 1 As shown, an air flotation structure for the wall of a low-energy automatic cleaning device is arranged in an ozone flotation reactor, including an annular water collecting pan 6 and a medium and micro-bubble cutting ring 7 sleeved on the inner column 1, and the annular water collecting The disc 6 is located below the medium and micro-bubble cutting ring 7, and is connected with the inverted U-shaped tube 4 with the solenoid valve 5 arranged outside the ozone flotation reactor. The top of the inverted U-shaped tube 4 has a vacuum breaking hole. The top of the ozone air flotation reactor is the slagging inlet 3, the slagging inlet 3 is connected to the slagging pipe 2, and the slagging outlet 10 of the slagging pipe 2 is downward and lower than the bottom 9 of the ozone air flotation reactor, and the height difference Mor...

An air flotation structure with low energy consumption to automatically clean the wall of the device. The invention aims at the phenomenon that the scum adheres to the top of the reactor and the surrounding wall during the slag discharge process of the vertical flow air flotation device, and realizes the automatic cleaning of the adhered scum by using the impact bubbles ;By setting the siphon conditions, the combination of the annular water collection tray with one-way opening and the medium and micro-bubble cutting ring, on the premise of ensuring the effect of air flotation treatment, the timely cleaning of the sticky residue on the wall of the device is realized; the invention adopts a low-energy automatic cleaning The air flotation method of the wall can clean the sticky residue on the wall in time, which is highly efficient and energy-saving.
Description
technical field [0001] The invention belongs to the technical field of advanced sewage treatment, and in particular relates to an air flotation structure for the wall of a low-energy automatic cleaning device. Background technique [0002] The air flotation process is an advanced treatment process for urban sewage. The micro-bubbles generated by the air flotation carry the pollutants in the water to form air floc particles, and the particles float and gather to form scum. Air flotation achieves the purpose of water purification by discharging scum to achieve solid-liquid separation. The top of the vertical flow air flotation process device is sealed with a slag discharge pipe, relying on the rise of the water level during the operation cycle to squeeze the scum into the slag discharge pipe for discharge, and then the liquid level drops to the normal height to continue working. During this process, frequent slag extrusion tends to cause a large amount of scum to adhere to th...
