Introduction
Purpose :For garbage recycling, the status quo at home and abroad, due to different start, the maturity of garbage disposal capacity and system is also different. Overseas countries have accumulated rich experience, while Chinas recycling technology is currently only piloted in a few cities, with few application examples. The author summarized and sorted out the references at home and abroad, analyzed the representative articles at home and abroad respectively, and elaborated the viewpoint and development trend of garbage recycling in this kind of articles, and then found the way to realize garbage recycling in our country.
Measure:Using SCI and CNKI databases, our team searched relevant journals with garbage recycling as the key word, classified and summarized the relevant journals, and carried out a literature survey on the topic of garbage recycling under the reasonable division of labor and coordination, and summarized the literature survey.
1. At present, the old ways of municipal solid waste treatment in China are mainly landfill, compost and incineration.
2. Residents individual factors, including the lack of knowledge of garbage classification, lack of corresponding knowledge of garbage classification. At present, the knowledge of garbage classification of most residents in China is relatively simple or even one-sided. Few people can consciously and actively classify garbage.
3. Garbage collection facilities classification confusion
4. There are also problems in the implementation of garbage classification system. Although the garbage classification Department has made the garbage bin classification system in the district beforehand, the municipal sanitation department will merge the garbage in order to save labor during the recycling process. This 'even pot end' method has seriously affected residents confidence in independent garbage classification, but also greatly offset the effect of pre-resident garbage classification, resulting in a certain malignant effect.
4.Some matching systems of garbage classification are not perfect. Such as rewards and punishment mechanism, propaganda and education system and other defects.
5. The cost of garbage collection is higher.
6. The results are not obvious: since the original Ministry of Construction announced the list of the first pilot cities for sorting and collecting domestic waste in 2000, nearly 20 years have passed. Although cities have been exploring new models for garbage control, it is undeniable that the results are not obvious. The average annual garbage output per city is 440 kilograms. 600 cities in the country generate 80 million tons of garbage.

Necessity of garbage collection
1.Harmfulness of the old methods of Disposing Municipal Solid waste: At present, the old methods of landfill, composting and incineration are still the main ways of Disposing Municipal Solid Waste in China. Most of these traditional methods have some disadvantages, such as waste of land resources, high technical requirements of composting, secondary pollution caused by incineration, etc.
2.High proportion of recyclable resources: Due to the characteristics of campus environment, waste generated by college students life mainly includes:Paper products, plastic products, a small amount of metal products and kitchen waste. Covered in teaching, living, dormitory, outdoorSite area. There are 2763 institutions of higher learning in China and about thirty million of college students.Nearly 20,000 tons, of which the proportion of recoverable resources is very high, should be well classified recovery.
3. garbage accumulation seriously affects urban development.
4. human happiness index and national significance
5. The significance of garbage classification and garbage treatment lies not only in solving the dilemma of garbage siege, but also in solving it.
It lies in the environmental protection itself, and its significance also includes advocating and forming a healthy lifestyle and promoting the livelihood of the people.Quality of Life and Subjective Well-being, Promoting Governing Ability and Public Credit of the Government, Improving National Quality and Public MoralityRecognize and improve Chinas international image in order to realize the 'strive to build a beautiful China and realize it' put forward by the Eighteenth National Congress of the Communist Party of ChinaThe goal of sustainable development of the Chinese nation.
Technical means
1.Intelligent System for Garbage collection: IOT technology with Ultrasonic sensor and Arduino Mega . To avoid the piles of rubbish , a project called IOT Based Smart Garbage System I will be implemented, which can be generate warning message to the municipality via SMS when the garbage bin is full or almost full, so the garbage can be collected immediately.
2. Fully implementing the dichotomy of dry and wet
3. Smart garbage monitoring system for waste management 。The proposed system is consisted by the ultrasonic sensor to measure the waste level, the GSM module to send the SMS, and an Arduino Uno which controls the system operation. It supposes to generate and send the warning messages to the municipality via SMS when the waste bin is full or almost full, so the garbage can be collected immediately. Furthermore, it is expected to contribute to improving the efficiency of the solid waste disposal management.
4. Validation of Microtox as a first screening tool for waste classification
Garbage biodegradation, also known as garbage digestion, refers to the destruction or mineralization of organic matter in garbage under the metabolism of microorganisms, so as to stabilize and achieve harmless g
