APPARATUS AND METHOD FOR WASTE WATER TREATMENT

摘要

Sewage and waste water inflow through a inlet pipe(18), earthy componants and large floating materials are eliminated in a sedimentaion tank(1) and on a bar screen(6) and sent to a balancing tank(4). Inflowed sewage and waste water are reacted with a sludge contg. soil micro- organisms which is recycled from a cultivation tank(11) and sent to the aeration tank(7) through a drum screen(6) by a motor(5). lnflowed sewage and waste water in an aeration tank(7) are reacted with a solid-liquid separated sludge in a sedimentation tank(8) with a sludge cultivated in a cultivation tank(11) by the compressed air of diffuser(13) to make the activation of soil micro-organisms. Metabolic product from micro-organisms and dissolved contaminant are coagulated, condensed and sent to a sedimentation tank(8) to separate water from a solid.
