Preferably, the sewage catalytic oxidation agent 213 is a liquid-solid catalytic oxidation agent, and the support frame 29 is provided with blind holes therein, so that the second water pump 22 can be conveniently conveyed.
The working principle is as follows: an operator opens the first water pump 111 on one side of the decomposition tower 2, the first water pump 111 sucks original sewage through the water inlet 18, and the original sewage is sent to the filter tower 1; the first filter plate 11 in the filter tower 1 can carry out primary treatment on the sewage which is just led into the equipment, and screen out larger blocks and partial small floating garbage in the original sewage, and because the second filter plate 12 in the filter tower 1 has smaller aperture, the smaller blocks of garbage are blocked when the original sewage passes through the second filter plate 12, thereby completing the primary treatment on the original sewage; because the first filter plate 11 and the second filter plate 12 all have an angle for water tower 41, consequently, when rubbish filters excessively, because rubbish self gravity makes rubbish slide mutually along the inclination of first filter plate 11 and No. two filter plates 12, slides to a drain 15 and No. two drains 16 to the problem of the unable work of sewage treatment device because rubbish piles up the cause has been solved.
The sewage after primary treatment is sucked by a first water pump 111 and sent to a decomposition tower 2; a first diversion plate 25 is arranged above the decomposition tower 2, and the sewage and the conveying pipe 24 after primary treatment are both arranged above the first diversion plate 25, so that the first diversion plate 25 can limit the discharge of the sewage and the conveying pipe 24 after primary treatment, the sewage and the conveying pipe 24 after primary treatment stably fall through a first diversion hole 27, and the stability of the flow speed is ensured; because the fan blades 212, the rotating shaft 211 and the bearing 210 are arranged below the first water distribution plate 25, the fan blades 212 are driven to rotate after the falling mixed liquid drops on the fan blades 212, so that the mixed liquid is fully stirred and mixed, and the contact rate of the sewage catalytic oxidant 213 and the sewage is improved.
The sewage after the secondary treatment is sucked by the water pump 111 and sent to the ozone disinfection and sterilization tower 3, and because the sewage is led in from top to bottom and the ozone is led in from bottom to top, the impact of water flow and bubbles is increased, thereby achieving the effect of full contact disinfection and sterilization; because the air holes 35 of the nanometer air dissolver 33 are smaller, the ozone is cut into small bubbles, so the contact area of the ozone and the water is larger, the mixing effect is better, and the disinfection and sterilization effect is better; because the ozone decomposition mechanism 5 is arranged above the ozone catalytic oxidation tower, the ozone which is processed in the ozone disinfection and sterilization tower 3 needs to be discharged thin ozone to be subjected to catalytic oxidation degradation treatment, the natural environment is protected, and the pollution of the ozone to the environment is reduced.
The sewage after the third treatment is sucked by the first water pump 111 and sent to the precipitation tower 4, and the wastewater after the third treatment can be precipitated and stored by utilizing the storage space in the precipitation tower 4, so that the treatment efficiency of the sewage catalytic oxidizer 213 and ozone on the sewage is improved, and the pollution to the environment caused by directly discharging part of the unvolated ozone in the wastewater is reduced.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
