PURPOSE: A processing method for waste water and a sewage and waste water treatment system are provided to have high aggregate efficiency and quickly condensate suspended solids in processed water by providing an effective total removing process that does not exist in previous water processing systems using conventional activated sludge. CONSTITUTION: A processing method for waste water comprises the following steps: condensing a mixture in a tubular reactor(100); precipitating the same in a precipitating tank(200) and withdrawing the precipitated sludge; and filtering processed water through a filtering device(400). In the third step, the filtering device is back washed, and the back washed water is returned to the water storage tank or the tubular reactor. In the precipitating step an inclined board is used. The filtering device may be formed with a rotary microdisc filter method or an up and down stream filtering method. The sewage and waste water treatment system consecutively comprises the tubular reactor, the precipitating tank, and the filtering device.
