SEWAGE, WASTE WATER AND HEAVY WATER TREATMENT SYSTEM USING BIOREACTOR SYSTEM FOR MICROORGANISM

摘要

PURPOSE: Provided are a system and a method for treating sewage, wastewater and reuse water, which are capable of greatly increasing biological decomposition efficiency of organic materials using a microorganism cultivator. CONSTITUTION: The method comprises the steps of (a) settling foreign matters and deleterious particles in a sedimentation tank, (b) screening the outflow of the sedimentation tank for removing large deleterious particles, (c) equalizing water flow rate by an equalization basin for adjusting load fluctuation of wastewater, (d) aerating the wastewater for decomposing organic materials by microorganisms, (e) introducing a portion of the aerated wastewater to a microorganism cultivator, culturing microorganisms in the cultivator and transferring the cultured microorganisms to the equalization step and aeration step, and (f) settling sludge of the outflow of the aeration step.
