摘要
A method and apparatus for treating sanitary wastewater using membrane filtration are disclosed. Designed principally for complete on-site sewage treatment and disposal, the system separates wastewater into liquid and concentrated solid components by membrane separation; then dries, disinfects, and deodorizes the solid component by a variety of methods to render it reusable or more easily stored and disposed. The liquid component is discharged or reused as is, or is further treated to render it disposable or reusable for particular applications. Alternatives for treating the solids component include mixing with alkaline admixtures and composting with other cellulose-based wastes. Alternatives for treating the liquid component include deodorization and biological stabilization by ultraviolet radiation and ozonation. Preferred and particularly advantageous embodiments of a membrane filtration system, a liquid treatment subsystem, a solids treatment subsystem, and a flushing subsystem are described.
