<p>PURPOSE:To prevent accumulation or corrosion of sludge and accelerate decomposition of organic substances generated by microbes by diffusing air from diffusion tubes revolving and moving in a treatment tank. CONSTITUTION:Hollow shafts 23 and 16 disposed at vertical angle to a central section 12 in a treatment tank 10 are revolved by a motor 15 through a reduction gear. The hollow shaft 23 is connected with an air feeding tube 25 by a revolving joint 22. Also, diffusion tubes 31, 32, 33 and 34 are branched radially in the horizontal direction along an inner bottom surface 10C of the treatment tank 10 from the hollow shaft 16. When the diffusion tubes 31, 32, 33 and 34 of said constitution are revolved and moved to agitate soil water in the treatment tank 10, and at the same time, foams of air diffused by the diffusion tubes 31, 32, 33 and 34 are dispersed uniformly in the treatment tank to prevent sludge from accumulating or corroding and accelerate proliferation of microbes to enhance decomposition of organic substances.</p> |
