COMPLEX TREATMENT EQUIPMENT OF ORGANIC AND INORGANIC WASTEWATER OF HIGH CONCENTRATION

摘要

PURPOSE: A complex treatment equipment of organic and inorganic wastewater of high concentration is provided, which convert the high concentration to low concentration by removing coarse impurities by more than 95 % and solid inorganic matter by more than 60 % at pretreatment stage. The organic matter of low molecular weight is removed at microorganism producing tank(3-10) thus activating microorganism. Foam generated from decomposing step of high molecules is separated and organic and inorganic matter are recovered and treated. Coloring matter is further removed by ozone treatment. CONSTITUTION: The system comprises four treatment equipments of first step, second step, third step and fourth step. At the first step, coarse impurities are removed and screw pressed to dewater before incinerate and separated liquid is fed to centrifuge to separate solid from liquid. At the second step, a secondary pretreatment centrifuge(2-4) is performed to separate microorganism and coagulate dissolved solid matter, the caked matter being moved to composting fermentation process. At the third step, digestion(3-3), microorganism production(3-10), filtering settlement are conducted. At the fourth step, centrifugal concentration(4-5), decomposing aggregation separation(4-3), and down ward filtration are conducted.
