<p>PURPOSE:To treat living waste water easily and efficiently with extremely slight, and in some cases, no energy consumption in the stage of treating the same by a biological membrane method by forming the biological membranes of anaerobic bacteria. CONSTITUTION:After waste water is immediately treated with an anaerobic treatment tank, it is treated, if necessary, with an aerobic treatment tank, and is released. More specifically, anaerobic bacteria stick and propagate on the filter meida in the 1st-3rd anaerobic filter bed chambers 1-3, and while the waste water flows through an inlet (a) to the arrow directions, the waste water is brought into thorough contact with sludge. Then, it can be released out from the chamber 3 in a fully satisfactory state in terms of control stndard. However, in places where the control standard is severer, it is equally well to discharge purified water through an outlet (d) by providing an aerobic filter bed chamber 4 in the final. The excess sludge is transferred with a pipe (c) and is discharged through a pipe (d).</p> |
