<p>PURPOSE:To perform completely the biological treatment of high-concentration polluted water by the procedure in which the inside of outer tank is divided into a separation chamber, a mixing chamber, and a aeration chamber by partition plates, the aeration chamber is provided with a flow guide plate and also its bottom is provided with a sedimentation chamber, and sludge is flowed toward the upper and lower parts of a contact oxidation plate provided at the cental part. CONSTITUTION:The inside of the outer tank 1 is provided with the partition plates 2 and 3 at intervals to divide it into the separation chamber 4, the mixing chamber 5, and the aeration chamber 6. The aeratin chamber 6 is also provided with the flow guide plate 6 at right angle to the partition plate 3, inclined toward the outer tank 1 side, and concaved on the partition plate 3 side at the water surface portion, and also its bottom is provided with the sedimentation chamber 9 leading to the aeration chamber 6. And, the central part of the aeration chamber 6 is provided with the contact oxidation plate 10, the upper and lower parts of or before and after which polluted water is flowed by an air jet from the diffuser pipe 11 on the opposite side of the flow guide plate 7 in order to completely treat high-concentration polluted water biologically. Also, the partition plate 3 is given the through holes 12 and 13 to circulate the polluted water to the aeration chamber 6 and the mixing chamber 5, thus keeping the concentration of polluted water constant and also preventing troubles with blocking, etc.</p> |
