Abstract

The invention discloses a system and method for recycling urban sewage. The system includes a sewage collection and sand settling unit, a water source heat pump, an anaerobic membrane bioreactor, a carbon resource recovery unit, a filter membrane combination unit, a nitrogen resource recovery unit and a phosphorus resource recovery unit. The resource recovery part, the sewage collection grit setting part is connected to the water source heat pump, the water source heat pump is respectively connected to the anaerobic membrane bioreactor and the filter membrane assembly part, and the anaerobic membrane bioreactor is connected to the The carbon resource recovery unit is connected to the phosphorus resource recovery unit, and the filter membrane assembly unit is connected to the nitrogen resource recovery unit and the phosphorus resource recovery unit respectively. The invention effectively recycles water resources, carbon resources, nitrogen resources, phosphorus resources and thermal energy resources in urban sewage, and greatly improves the resource utilization rate of urban wastewater.

Description

technical field [0001] The invention relates to the technical field of waste water recycling, in particular to a system and method for recycling urban sewage. Background technique [0002] In the context of the global advocacy of sustainable development, as far as sewage treatment is concerned, it is in line with the concept of sustainable development to reduce the waste of resources and energy, reduce the impact on the global environment, and realize the recycling and reuse of resources while achieving sewage treatment standards. Most of the sewage is water resources, followed by carbon resources, nitrogen, phosphorus and heat resources. [0003] Anaerobic membrane bioreactor (AnMBR) has many advantages such as completely intercepting sludge, good effluent quality, low sludge yield, small footprint, and recyclable carbon resource production capacity in sewage. It has shown great promise in urban sewage treatment. It has a good application prospect. However, at ambient tem...
