Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as Figure 1~Figure 6 As shown, an oxidation ditch scum removal device is composed of a slag cleaning tank 1, two tank bases 2, an overturning system 3, a spraying system 4, a slag discharge system 5 and a slag bucket trolley 6.
[0027] The slag cleaning tank 1 is composed of a U-shaped groove 11 , an end plate 12 , a trunnion 13 , a rib plate 14 , a spray hole 15 , a slag outlet 16 and a gusset plate 17 . The end of the trunnion 13 is spherical or cylindrical, and is welded to the end plates 12 on both sides; the ribs 14 are radially spaced along the length of the U-shaped groove 11, and the slag outlet 16 is arranged on one side of the U-shaped groove 11. In the lower part, the gusset plate 17 is welded to the upper corner of the end plate 12 on one side.
[0028] The tank seat 2 is composed of a bottom plate 21 , a b...

The invention relates to a dross removal device for an oxidation ditch. The dross removal device comprises a dross removal tank, a tank body seat, an overturning system, a dross discharging system and a dross hopper car, wherein the tank body seat is fixed on the wall of the oxidation ditch, the dross removal tank is a U-shaped long tank on the tank body seat, a connecting rod of the overturning system is hinged with a gusset plate on a U-shaped end plate of the dross removal tank, and a taphole is formed in the lower bottom of the dross removal tank, is connected with a hose of the dross discharging system and extends to the dross hopper car. The dross removal tank can freely float to block dross along the height of the water level of the oxidation ditch, the U-shaped opening of the dross removal tank is immersed under water through the overturning system, the mobility or defoaming of the dross is enhanced by a sprinkling system, and eventually, dross liquid is discharged to the dross hopper car outside the oxidation ditch. The dross in the oxidation ditch is timely treated according to actual situations, the treatment method is simple and convenient, the device is reliable, the manual removal and fishing are not needed, the wastewater treatment cost can be effectively saved, the labor intensity of workers is reduced, the adverse consequences of an oxidation ditch treatment process is avoided, and the application value is high.
Description
technical field [0001] The invention relates to auxiliary equipment in a sewage treatment process, in particular to an oxidation ditch scum removal device. Background technique [0002] Sewage treatment oxidation ditch process technology Oxidation ditch (Qxidation Ditch) is called Continuous Loop Reactor, which was first built and put into use in 1954 by Dr. A. Psaveer in Washoben, the Netherlands. Oxidation ditch process is currently the most practical process for urban sewage treatment. It has been used for many years and lasts for a long time. In recent years, about half of the newly built urban sewage treatment plants in China have adopted oxidation ditch process. The reason is that the strength of the development of oxidation ditch technology lies in the circulation of the oxidation ditch. The process is simple, easy to manage, the sludge output is small and stable, impact load resistant, the treatment effect is good and stable, and it has good nitrogen and phosphorus r...
