Domestic sewage cleaning system

摘要: The present invention provides treatment of domestic sewage containing oil. resulting products will be purified water, dry fertilizer, and fuel (gas liquid) no contaminants that could pollute the environment. After initial settling process, two parallel flows are created: one liquid plus crude sediment (0.2 mm greater) other fine particles (less than 0.2 mm), latter termed "settled sewage". treated separately. settled after in a low-pressure separator separate out fuel, followed by aeration, ultrafiltration, finally sterilization ozone or chlorine, results pure water. biochemical sediments production gas mainly methane solid product drying disinfecting is converted into fertilizer. system comprised fire chamber recuperator which allow for utilization to reduce energy expenditures cleaning process.
