The Feasibility Study Of Municipal Domestic Refuse's Integrated Disposal Project In Baotou

Nowadays, the urban area of Baotou produces domestic refuse about 1200t/d, all the refuses are disposed with the way of sanitary landfill , but the disposal method has some defects ,for example, the floor space is very huge, the method of refuse disposal can't realize resource recycle, some wastes which can be reused are buried, the disease germ may be spread because of the harmful germ that can't be disposed in time, the surrounding environment and groundwater of dumping site may be polluted potentially. The present status of Baotou's domestic refuse disposal that has influenced seriously the city sustainable development of society, economic, ecological environment and the impression of the civilized city. So, the city government of Baotou propounds that they will adopt integrated disposal method to solve the problem of Baotou's municipal domestic refuse disposal, and Baotou's municipal domestic refuse disposal that will realize the total requirements of the innoxiousness, reduction, resource recycle.This subject analyzes the present status and development trend of domestic and international municipal domestic refuse disposal , according to the characteristic of municipal domestic refuse in Baotou and through analysing and screening all kinds of domestic refuse disposal craft, the subject puts forward a craft technical scheme to dispose Baotou's municipal domestic refuse synthetically through adopting introduced Enhanced Autogenous Thermopile Aerobic Digestion (EATAD) craft of Canada and supporting sorting disposal neck and producing fertilizer disposal neck to produce high-efficient and biological organic fertilizer . The paper has confirmed some relevant craft design parameters through a semi-industrial test to proof and optimize the EATAD craft that is used to dispose municipal domestic refuse. According to the producing situation and composition characteristic of municipal domestic refuse in Baotou., to utilize semi-industrial test result of the EATAD craft, and to synthesize national mature refuse sorting disposal and producing fertilizer disposal craft technic, the paper has finished an engineering feasibility study of municipal domestic refuse's integrated disposal production line in Baotou ,the project scale is 500t/d, the paper proofs the process rationality of the refuse's integrated disposal production line and calculates the process material balance through analyzing, and according to the engineering feasibility study's scope and the degree of depth ,the paper provides the craft equipment list, process chart, material flow ,layout and profile chart, and completes investment estimation and cost analysis of the project.The research of this subject will offer a detailed and feasible craft scheme for the implementation of municipal domestic refuse's integrated disposal project in the city of Baotou, the subject will offer a design reference for the related departments who decide to implement this project in the future, the subject will create some conditions for the constructing and implementing of the project, the subject will also opened up a new path for the municipal domestic refuse's resource recycle in our country, the research of this subject will meet the requirements of the nation develops recycle economy and implements sustainable development strategy, the research findings of this subject will have some promotion meanings.
