摘要

[Objective] The aim was to address the difficulty of long pipe for centralized sewage treatment in campus life and difficulty in use.[Method] Though the four integrated approach of fermentation tank,coal ash slag filters,chemical and biological membrane reactor and separation of heavy metals in electromagnetic fields,the green wastewater treatment system in campus life was designed to realize the recycle use of sewage in campus life.[Result] The processed sewage can flush the restroom.The sludge in the processed sewage can feed earthworms,while earthworms(material or production servers) were food for chickens and ducks and the compost of earthworms was fertilizer,which brought promising economic and social benefits.Tests showed that using the green treatment system to process campus sewage can achieve or pass national second emission standard.Process charge was 50% lower than the centralized sewage processed company and the treatment process was completely greenized and recycling rate was high.
