摘要

[Objective] The aim was to address the difficulty of long pipe for centralized sewage treatment in campus life and its difficulty inrnuse. [Method] Though the four integrated approach of fermentation tank,coal ash slag filters,chemical and biological membrane reactor andrnseparation of heavy metals in electromagnetic fields,the green wastewater treatment system in campus life was designed to realize the recyclernuse of sewage in campus life. [ Result] The processed sewage can flush the restroom. The sludge in the processed sewage can feed earthworms,rnwhile earthworms ( material or production servers) were food for chickens and ducks and the compost of earthworms was fertilizer, whichrnbrought promising economic and social benefits. Tests showed that using the green treatment system to process campus sewage can achieve orrnpass national second emission standard. Process charge was 50% lower than the centralized sewage processed company and the treatmentrnprocess was completely greenized and recycling rate was high.%[目的]解决校园生活污水集中处理管道铺设过长和不方便再利用的困难.[方法]通过发酵池发酵、煤灰高炉渣过滤器、生化膜反应器和电磁场重金属分离器4级综合处理,设计该校园生活污水的绿色处理系统,以实现校园生活污水的循环利用.[结果]经处理后的校园生活污水可以用来绿化、冲厕所;用污水处理中的污泥养殖蚯蚓,蚯蚓用来养鸡鸭(或生产伺料),蚓粪作为肥料,可带来较好的经济和社会效益.试验表明,采用该生活污水绿色处理系统对校园生活污水进行处理,处理后的水质完全可以达到或超过国家二级排放标准,处理费用比以往集中污水处理厂处理降低50%,而且处理过程完全绿色化和污水再利用率高.[结论]该生活污水绿色处理系统用于校园生活污水的处理是可行的,且有较好的经济效益,值得推广应用.
