PROBLEM TO BE SOLVED: To solve the problem that a method by microorganism-decomposition is necessary for treating wastewater without generating sludge, it is difficult for a conventional method to keep an average decomposition capacity throughout the year, and there are many methods by external microorganisms, in which a decomposition capacity is unstable and which increase costs and may cause environmental pollution. SOLUTION: The flow of wastewater is divided into a raw water channel having a decomposition channel and a microorganism channel having a culture channel, each channel has an ORP controller, seawater is mixed in the culture channel, microorganism groups are cultured without being affected by the variations in raw water quality, temperature, and weather, and the microorganisms are supplied continuously to the decomposition channel, so that the generation sludge is controlled, and polluted water can be cleaned independently of external microorganisms. |
